Re: [RE-wrenches] Anyone heard of Tesup?
With a 7.38 square foot swept area you can assume that they forgot the decimal point. At best, this is a 900 watt wind turbine, probably at 28 mph or higher. Looks like they are using the old Whisper 900 (h40) blade set as well so yeah, 900 watts. Install more solar instead!

Re: [RE-wrenches] Water system with Grundfos SQFlex

I'd think that with a positive displacement pump it would not, except very slowly or if it turned the motor backwards which I think would be very unlikely. There is about 100 psi head on the pump. I think it's most likely I have a leak somewhere in the plumbing, and of course another failed check valve farther up in the plumbing. It's possible to get failures even with redundant protection if you have two concurrent failures, which I must have here.

Re: [RE-wrenches] Electrolyte level measurement
And to add to Steve's good advice, make sure the sprayer has a plastic wand. Some are made with brass wands and that can add a degree of excitement that I can live without. I also only fill when the batteries are mostly charged. That lessens the chance of the cell being overfilled as the state of charge increases. Oh...and a headlamp helps to see the fluid level, just cock you head and you'll find just the right angle to see the fluid.

For example, the Rolls L16's fill tube is 1 inch so I would make the mark 1.5 inches.

Of course it's a 4-hour drive from my office. During winter snowstorms (when they need the AGS the most of course) the generator had only about 50:50 chance of starting. So I'd travel to the site (sometimes just the client would do it and I'd guide him by phone), pull up the Gen menu on the Mate 3S, hit ON and it wouldn't start. No bueno. Walk up to the generator (propane with Honda engine) and verify it's on Auto. Start it with the main switch to ON, starts right up, so not a gen battery problem. Run it for an hour or so, stop it with the switch on the gen, put it back to Auto, and everything works perfectly from Mate 3S AGS for 1-2 days, including remote start from OpticsRE. Then the problem (sometimes) comes up again when nobody is there. I just happened to hit the site at exactly the right time last week right as a big snowstorm was moving in, and was finally able to figure it out with really good raingear and a multimeter: The Outback Flexware remote gen start relay OBR-16-DIN was icing up internally, I had added it in the gen compartment when we upgraded the client from an old Trace SW to an Outback (SW had a big AGS relay, Outback sent a 12VDC signal to trigger the external relay we added). DIAG - new Outback OBR-16-DIN relay would get frosty internally when high humidity snowstorms would move in, that's why it sometimes didn't work from the Mate 3S or OpticsRE. Run the gen for an hour, the internal gen compartment warms up, the frost melts off of the relay, then all the AGS from Mate 3S and OpticsRE works fine. Have any of all y'all run into this problem, and is there a more reliable relay to use that won't ice up? not outside exposed to weather, but inside the outside gen enclosure. I have zero space available in the VFX MNDC enclosure in the house to put in the Flexware AGS relay, it would need a separate enclosure. The easiest solution I can see is just find a relay to fit into the gen compartment that does the same as the Outback version, but doesn't ice up. Thanks in advance for any and all suggestions.

Dave, You're not far from me, so I know that the temperature at the site has been well below freezing at night. After running a series of cheap generators here for many years I can tell you that there's likely water built up at the bottom of the fuel tank. This freezes and constricts fuel flow which of course affects generator rpm and thus voltage and frequency. So check for that but as everyone else has said so well, it's the generator.

Re: [RE-wrenches] Mate3 verses Mate3S
Tump, I have a system exactly like this one and had similar AGS issues. Once we ruled out conflicts between the internal Aux commands and the AGS menu in the Mate, we eventually figured out it was heat related. We were using the top inverter on one of the quad stacks for AGS and that inverter ran hotter than the others. The genset would start as expected but the shutdown was extremely erratic, sometimes running for 10-15 hours if someone didn't catch it right away. The problems stopped when we moved the AGS function to the bottom inverter. Such a simple solution that took far too long to figure out. I hope the solution to your issue turns out to be as simple (and cheap!) as mine.

Most problems have been blades, brushes and a few tower failures mostly due to customer neglect or violent storms. I installed a Pika 1.6 kw at my home about 4 years ago and fell in love with that machine. Pika solved the Blade root attachment weakness found on the Bergey as well as sound issues and performance. Unfortunately they stopped production due to low sales. I ran mine for a year and a half and almost eliminated my generator in a low wind speed site but att he same time saw it perform flawlessly in high winds putting out well over 2500 watts and regulating my batteries at float with no dump loads needed. I got my first order for one and called Pika to order one but they had already stopped production and were not going to make any more. I had sold a customer a complete upgrade of his system which included upgrading from a Xantrex SW Plus to dual Outback inverters, going from 24v to 48v, and directly replacing his Bergey with a Pika, and new Aquion batteries. Sine we had already done the rest of the system, I ended up selling mine to him to keep him happy. I dearly miss that machine. Since Pika sold out to Generac, I’m hanging on a glimmer of hope that the turbine production could be resurrected. Otherwise, the only new turbine I have installed is a 1 kw SuperWind, made in Germany. It is on a 40’ tilt up guyed tower on a mountaintop transmitter site. It has performed as expected with the only problem being susceptible to icing and the blade hub freezing to the nacelle. It is all white so the sun can’t help defrost it. Very nice workmanship but it also has a controller and dump load In addition to pitching blades. Similar cost as the Pika. I don’t have any data on how much the dump load has interacted with the controller. This is a high wind site. I’m not sure how it would perform in low winds. We put it up in November and it survived the winter. If you could find a used Pika, that would be my choice but I haven’t found one yet myself. Let me know If you find anything else.

Re: [RE-wrenches] Bergey XL.1 HummmBuzzz
Matt, What you are hearing is alternator noise. It's caused by the vibration from the permanent magnets passing by the alternator coils. All turbines produce some alternator sound, some more than others and the tower itself can act as a resonator, amplifying the sound. The reason you don't hear it when the turbine is unloaded is because no current is being induced in the alternator coils, so there's no resistance pushing against the rotor magnets. Unfortunately, there's nothing much to be done about it.

I have a customer with an older XL.1 on a tilt-up tower. The machine has been in place since 2007. I've done some work to it over the years including blades, yaw bearings, painting, slip rings, brushes, rectifier. The machine/property has a new owner who finds the noise of the machine to be objectionable. The original owner also noted the noise, but was not as dogged about resolving it. The noise is best described as a "hummbuzzz" and it happens when the machine rpms have slackened and then begin to accelerate again. The transition causes some kind of electrical harmonic that is not noticeable once the rpms increase. So, if the machine furls out of a high wind and the rpms drop then the noise begins as soon as it un-furls and the blades begin to accelerate. The noise disappears as it comes up to speed. This noise does not happen if the machine is allowed to run unloaded (with the breaker in the off position). Anyway, I'd sure appreciate any thoughts.

Re: [RE-wrenches] Battery Transport
In the early 90s and for 2 years, I drove for an expedited freight company. I had my radmat, hazmat and secret service endorsements. We had to know when to placard when under a hazmat load, where and when we could and could not travel, safe haven locations, etc. It's the RQ amount of the hazardous substance that dictates the procedure. The RQ tables can be found here: https://www.phmsa.dot.gov/staticfiles/PHMSA/DownloadableFiles/Files/172_101_appa.pdf When I started my RE company 21 years ago, the first thing I did was look into the potential issue of transporting batteries. The RQ amount for sulfuric acid or sodium hydroxide is 1000 pounds.that's not battery weight, it's the electrolyte weight. And that's a LOT of battery! Of course, Lithium is likely a different story so all I can suggest is research it. So, as others have stated, proper securing of the load, obeying traffic laws, etc. is sufficient.

"Selling to grid" is not enabled for complicated reasons, so here's the problem. Each day at sunup, the Midnite charge controls implement a new 3 stage charge cycle including a lengthy absorption interval. The batteries require frequent water additions and there may be other deleterious effects from running a complete bulk/absorb charge every day on a battery that's already highly charged. Possible solutions: (1) We could tweak the Midnite settings for a short absorption interval with less gassing...but if a prolonged grid outage should develop we would wish the absorption interval had not been shortened. (2) Your suggestions here, please. The client would be willing to update and/or reconfigure their Midnite software if that would help or the client would even consider hardware revisions. We chose the Midnite controllers in 2011 largely because of their 250 volt input ceiling, btw. Thinking ahead to my future but similar projects: Does any DC charge controller know that a new absorb cycle is not needed each day provided that the battery never dropped below Float the night before? A full cycle would still be wanted every 30 days or so just to stir things up, so that's almost like a 30 day equalization trigger only it would be a bulk trigger instead. OR: would "selling to grid" avert this problem since the "battery backup with grid tie" type inverter is aware that the battery never left the Float stage? OR: would AC coupling also avert this problem even if "sell to grid" is not enabled, for the same reason cited above? OR: Your suggestions here, please. Thanks Jolliness, Mechanix.

Well, pond, spring box? How many gallons per day (GPD) do you need delivered, on average? GPD is a much more useful figure for sizing PV-direct pumps. Is that 600 ft of head measured from the standing water level to the top of the storage tank, as just elevation change and not distance? A 600 foot-deep well might actually have a standing water level at 300-400 ft. Even if the pump is set at 600 ft, it only takes energy to lift water from its standing level, so your head figure would be inaccurate if that is the case. If it's a well, what is the diameter of the well casing? What are the peak sun-hours at the site during the darkest time of year that the water is needed?

Re: [RE-wrenches] 72-cell modules
Allan, We just finished replacing a BP SX170 pole top array under warranty and BP provided us with the Ameresco 4190J modules. We had to install cords with the MC4 connectors on the J-boxes but other than that, they bolted right in. The dimensions are almost identical to the SX-170 and the bolt holes line up nicelyand they are a 72 cell module.

Now we really need some. We have a good customer for whom we put in an off grid system in 2006. 48V, 27 BP SX170 modules on three Wattsun trackers. Each tracker holds nne modules, wired as three 72V strings of three modules each. Yes, the notorious SX170s. Four with burn spots were replaced in 2008, 6 more in 2010, and now ten more failed or are showing discoloration. BP's warranty contractor has agreed to replace the wattage equivalent of 23 of them at $2.00/W. They will either ship us replacement modules or send a check for purchase of replacements elsewhere. The problem is that their only offerings are 60-cell modules, which won't fit the trackers. BP got out of the solar business before the standard configuration went to the larger 156 mm cells. I would have appreciated a serious corporate effort to procure warranty stock of modules that were most like the ones manufactured by BP, so that they would more readily replace their warranty failures. That apparently is not to be. The SX170s are 31.1" (790mm) by 62.8" (1593 mm). I need to locate some 72-cell modules in this standard dimension range. We'd probably buy 27 of them, once we determine that the replacements can be fit to the racks. Can anyone suggest a brand/model/supplier etc.?

Re: [RE-wrenches] Replacement for Whisper 500
Nathan, Unfortunately, this is a common failure mode for that turbine. A 2 bladed turbine is an unbalanced turbine and the vibration is not kind to welds, blades, etc. Although the Bergey XL.1 1kW turbine is a decent machine, it's not a replacement for a 3kW turbine. Bergey does have a 6kW unit but that's a spendy unit and likely not appropriate for this client. I'm with Chris on this.check out the Kestrel from Eveready.

Re: [RE-wrenches] CU 200 error
Hi Bill,
The dreaded F3..with over 40 Grundfos
systems out there, I've seen several of these.
The most likely cause is a bad connection and
the most common of those are the splices
underwater.
I hate to say it but it can also be a bad
CU200. I've seen the internal modems go bad.
First test is to jumper the power
directly to the pumpif it runs, it's likely
the CU200.
If not, it's either wiring or
the pump.
If this is PV direct and the
weather looks iffy, bring a 36 or 48 volt power source with you.
We have a standard deep
cycle battery box with 3- 21 AH sealed
batteries in series that we use.
And when
all else fails, pull the pump, cut the wires on the
pump side of the splice and test the pump.
You will need a
4-6" piece of PVC pipe, capped
on one end and filled with
water for this test because
of the dry
run sensor built into the
pump wiring.
This is my experienceI'm
curious to see what others say.
Good luck!

Wrenches,
I have been asked to repair a Grundfos SQ
installation for our area Land Trust. Pump is not pumping and
the controller (CU200) is throwing a code of: F3. The manual
says loose wires, bad connection, failed CU200or failed pump.
I'm looking for more experience than mine in these matters
before I drive the 3 hour round trip out there for the repair
for: most likely issues, tests to conduct, tools, spare parts
(controller??)..
Thanks in advance,

Re: [RE-wrenches] outback fx series inverters
Sounds an awful lot
like "Wind Turbine Syndrome'
And for that, tests are now showing that WTS is
a "communicated" disease.
The power of suggestion.
Perhaps this is also a communicated
disease.unfortunately, with psychosomatic symptoms manifesting in
those affected.

As you can imagine, existing in our current society is

propane 'fridges since they use no electricity and don't
cause them to have that 'pins needles' feeling they
get when they are near electrical fields. I try not to

me, "I can't stand to be near anything electrical". So
perhaps there needs to be some sort of independent test to

Re: [RE-wrenches] BZ Products Charge Controllers
Nathan and Dan, We've used the BZ 250 and 500 MPPT controllers here in our shop. They worked well until we used them on our 2 meter amateur radio repeater solar/ battery power supply system. For some reason, they were overly sensitive to RF from the transmitter and the front ends blew in both units. In the interest of full disclosure, this was several years ago when these units first came out and they may be much more robust now. And you are correct, they do fill a current and price niche!

Re: [RE-wrenches] Bergey XL1 and the Classic controller
Hi Chris,
Other than the increased cost for the additional
equipment, I like the new high voltage XL.1.
I have one in the field, running for almost
one year now. Took about 1 hour to work
through
the Classic/ Clipper programming but
then everything worked perfectly. And
no call backs!!!
The customer is
thrilled with it.
We saved a bunch of money on the
smaller wire run and the turbine produces more
energy
for the client than any of the 14
standard issue XL.1s I have out thereand it's not in as good of a wind
resource as some of the
others.
So, other than the learning
curve on the part of the installer, I see
no glitches. And the customer
service at Midnite is second to none (hi Ryan!) so
even the learning curve is painless.
FYI- I have the
Classic/ Clipper at my place now. It's now controlling my
legacy Whisper H1500.
(The
old World Power Tech. unit with
the big alternator, not the 1kW
SWWP unit)
It sure beats
the good old "EZ-Fire" controller.so
far, so good!

I would be willing to bet that Edison was really close with his 100 year estimate.on his batteries. I would not want to make that same claim with batteries from other sources.

Message-ID: e1fd9211d08550b141810da0059d2...@mail.gmail.com Content-Type: text/plain; charset=iso-8859-1 Hi Eric, We've used TTi, EcoFasten, and Quick Mount. I like Quick Mount the best but they are a bit pricy so we've been using Eco Fasten for the majority of our work over the last year. If anything, I've found that TTi requires more labor and is more likely to require shingle cutting plus I'm gun-shy about their material quality. That said, the majority of our standard comp shingle mounts require no shingle cutting (although you might have to remove a nail or two) with Quick Mount or Eco Fasten. You just slide them up under the shingles as pictured in this video: http://www.quickmountpv.com/training/videos/classic-comp-install.html Maybe you have a different kind of comp in your neck of the woods? If you're really worried about it you can always take a sample out and see if you can slide it under the shingles without any cutting. It just might work. Good luck.

Thanks guys. Talked with TTi and mentioned Mr. Miller's experience with rust. They said they got a lot of feedback about this problem on their 1st generation line and have since corrected the issue. I'll remain cautious...thanks Willy. TTi, DPW, EcoFasten, and Quick-mount all seem to have the same issue of lacking versatility in height adjustment. Anyway, going to check out a sample from TTi. DPW and EcoFasten look like they still require cutting of both flash base and comp courses. I'm trying to avoid cutting anything as I want to avoid disturbing original flashing and original roofing material. Thanks for all your input!!

Re: [RE-wrenches] Kohler 8.5 RMY question - and Generac
Allan,
Thanks for the positive feedback on Generac.maybe this old dog
really can learn new tricks.
But in the mean time, I'll live vicariously through you and others
who purchase these gensets.
Thanks for testing these for the rest of us! ;-)
I have one Kohler 8.5 RMY in the field, still running from 1997 with
4,210 hours on it.
It's the air cooled, 3600 rpm unit, so I was surprised at the
longevity. It has been serviced
regularly by the homeowner and had a couple of minor parts replaced.
I would not consider that 8.5 RMY to be at the end of it's service
life at 2,000 hours IF it has
had regular service. Are there service records on site?

Roy and all,
While I appreciate the dialogue that my request has generated, not
a single post has addressed my question. So I'll give it one more
try: What kind of runtime hours have you seen with the Kohler 8.5
RMY?
Also, in a recent Home Power "Ask the Experts" column, I spoke
positively about the new Generac "EcoGen" 6 kW model as a
well-designed and well-engineered unit specifically for off-grid
residential applications. It's quite different from their
mainstream models, designed specifically to hold up under off-grid
usage. Having been involved with this list since about 2000, you
can bet I have read plenty negative about Generac over the years.
So both the Home Power recommendation and a previous post speaking
positively about it were carefully considered before they went out
(my wording in Home Power was "it
has caused me to favorably reconsider Generac for your type of
application"). I have had one of these units in my own
off grid home for about a year, and am quite favorably impressed
with it. It has to date performed without flaw, has very good
built-in diagnostics and a record of usage history, and runs cool
and quiet. So I am encouraging those who have had bad experiences
with Generac to take another look at this particular model. We
have needed this on the market for several years now, ever since
the generator manufacturers began focusing on "home standby" as
the next growth market.

Hi Drake, The Air 403/ Air-X/ Air Breeze/ whatever it's name is now, is fairly dependable. In most wind regimes it's the equivalent of a 10 or 20 watt solar module but seems to work just fine. FYI- it's ~ 200 watts or so. It's not the quietest thing though, being a fairly high rpm turbine. But the Sunforce 600 is not a 600. The rotor diameter tells the truth, making it somewhere around a 200 - 250 watt machine. Perhaps they have the bugs worked out but when they first came out, there were many reliability and performance issues. What's the application for this?

Hi Dick, Kestrel is going through certification at this time. This is good news, as this will help them enter the US market with some established credibility. It has the potential to be a good turbine. And with the Eveready battery company behind them, they should have the capital needed to be a solid company. Last I knew, they do not have a US distributor. Too bad because I want to test one here! FYI- I had the opportunity to dismantle and reassemble one in a course I taught in 2010.

Re: [RE-wrenches] battery venting
I agree with Michael. I would try to avoid pressurized battery boxes. I also want to add that I have always followed the 360 degree limit for vent pipe bends. I have also learned that even though the Zephyr vents can be replaced, most of them run so quietly that most end users don't notice when they fail. Yes, that's another great argument for regular inspections. I have been using 3 vent pipe with a minimum 60 cfm, brushless, sealed motor vent fan, mounted so that it pulls the gases from the box and up the pipe.

Other than the quirkiness of their need for fine (10 micron) filtration on the intake side, and the relative unreliability of the optional dry run protection thermal snap switch, the pumps are exceptionally well-made and long-lasting, in my experience. Early (before around 1998) pumps were sold under the "Flowlight" name; then under "Dankoff Solar Pumps" name until Conergy bought Dankoff around 2004. The pumps had Conergy's name on them until around two years ago, when Conergy closed its sales and distribution of water pumping, solar thermal, and wind products. Innovative Solar bought the water pumping line and restored the "Dankoff Pumps" name. Innovative Solar became Argand, and changed their distribution model in order to not compete with their dealers (attaboy!); Dankoff Pumps, while owned by Argand, is wholesale only; new dealers must place a minimum stocking order. The pumps continue to be manufactured here in Santa Fe by the same folks that have made and serviced them for years, and quality and support remain high. Dankoff Pumps website is currently www.Dankoff-Pumps.com. Note the hyphen; www.Dankoffpumps.com takes you to a (currently closed) online store, with referral links to Dankoff Pumps for dealers who want to become dealers. Dankoff Pumps will soon be either moving to or adding www.DankoffSolarPumps.com as well, I understand, but this hasn't happened yet. Contact Dankoff Pumps at m...@dankoff-pumps.com. The Procon heads wear out. New replacement heads are available through Dankoff Pumps (and probably other sources as well). However, the heads are rebuildable, and the cost is much less than new. We always ask customers for their old pump heads in exchange for new or rebuilt ones. The rebuilder is Edco Service Center, 8220 Belvedere Ave., Suite F, Sacramento, CA 95826; 916-454-1445. The contact person there is Sandie, san...@edcodistributing.com. Recently we learned some critical information related to pump rebuilding: the heads may rebuilt in many configurations, and it's essential to specify that the pump heads must be for potable water applications. This has to do with the amount of lead in various internal components. According to Sandie at Edco, you must specify a 114E head. According to Matt at Dankoff Pumps, the full designation is 114E240F11XX for the Booster Pump head and this should be specified in full. All original Booster Pump and Slowpump heads were acceptable for potable water; however, due to a mixup of indeterminable cause, we were recently sent a set of 104 rebuilt heads, which aren't (according to the State of California) suitable for potable applications due to lead content. To their credit, Edco will re-rebuild these heads to potable standards at no cost to us save shipping, but this seemed to me to be a good opportunity to share this information widely with other water pumping Wrenches.

I looked around on the NERC www site without finding the report mentioned. Any other wrenches seen anything about this experiment? Jim Duncan By Seth Borenstein The Associated Press WASHINGTON -- A yearlong experiment with the nation's electric grid could mess up traffic lights, security systems and some computers -- and make plug-in clocks and appliances like programmable coffee makers run up to 20 minutes fast. "A lot of people are going to have things break, and they're not going to know why," said Demetrios Matsakis, head of the time service department at the U.S. Naval Observatory, one of two official timekeeping agencies in the federal government. Since 1930, electric clocks have kept time based on the rate of the electrical current that powers them. If the current slips off its usual rate, clocks run a little fast or slow. Power companies now take steps to correct it, keeping the frequency of the current as precise as possible. The North American Electric Reliability Corp., which oversees the U.S. power grid, is proposing an experiment that would allow more frequency variation without corrections, according to a June 14 company presentation obtained by The Associated Press. The test is tentatively set to start in mid-July. Tweaking the power grid's frequency is expensive and takes a lot of effort, said Joe McClelland, head of electric reliability for the Federal Energy Regulatory Commission. "Is anyone using the grid to keep track of time?" McClelland said. "Let's see if anyone complains if we eliminate it." No one is quite sure what will be affected. This won't change the clocks in cellphones, GPS or even on computers. But wall clocks and those on ovens and coffee makers -- anything that flashes "12:00" when it loses power -- may be a bit off every second, and that error can grow with time. VCRs or DVRs that get their time from cable systems or the Internet probably won't be affected, but those with clocks tied to the electric current will be off a bit, Matsakis said. According to the June presentation, East Coast clocks may run up to 20 minutes fast over a year, but West Coast clocks are only likely to be off by eight minutes. In Texas, it's only an expected speedup of two minutes.

Re: [RE-wrenches] Air conditioning for batteries in high temperature climate
Bob is correct, I do have an off grid client that uses an AC unit to
keep the batteries cool.
Although we're not in a high temp climate, it does get into the 80's
and low 90's here
in the summer.
By my calculations, he was losing an 'average' of 10% storage
capacity during the 5 month
period from late spring to early fall. In July and August it was
closer to 18%, but for calculation
purposes, 10% is close enough. His bank capacity is 4800AH @ 48 VDC.
That's 230,400 watt hours
and 10% of that rounds out to 23,000 watt hours lost to heat.
I showed up one day to check something in the power shed and was
dismayed to see a window
AC unit installed there. An interesting customer discussion ensued
and I had to admit he was
correct in his calculations.
The Energy Star rated AC unit consumes no more than 3,000 watt hours
per day, even in the
highest heat. Essentially, he's 'spending" 3 kilowatt hours to 'buy
back' 20 kilowatt hours of
storage. He got me on that one!
That reasoning didn't work on the 6 other AC units that appeared on
his house the following
week. But that's another story altogether!

Re: [RE-wrenches] Air conditioning for batteries in high temperature climate
Hugh,
Correct to a point. But if we added 10% capacity, we would need to
add a bit more
charging capacity (PV/wind) and it begins to spiral up in cost. Much
as I hated to see
that AC unit there, it was still the more cost-effective solution
for that specific system.
FYI- with the AC unit, we also eliminated a heat issue that we'd
been dealing with on the
upper Outback inverters on his dual quad stack setup. Yes, we had
active ventilation, 4 levels
to be exact but the fans themselves became part of the problem with
the increased power
consumption.
So bottom line, because we killed 2 birds with one AC unit, I think
it was a good move.
And I've worked (successfully) to avoid ever having to use one
again. I really do prefer simple,
passive methods for solving problems like these.

Kirpal, Although I can't answer your IO101 question, I can tell you that the SQ Flex operates nicely for us when used with a pressure tank/ pressure switch. As long as the pump and PV power source are sized to accommodate the additional vertical lift caused by the tank pressure, all is good. As for the 2 current carrying conductors, that still fascinates me. When using 240 AC, the 2 phase wires from the grid are attached to the blue and brown wires from the pump. When switched over to the array, the DC positive and negative are attached to the same brown and blue wires but the polarity doesn't matter. It's all taken care of by the electronics in the pump. Takes a while to get used to that. And have you seen the documentation that comes with the pump and CU200?

From Russ: We just had a situation involving Quick Cote on battery terminals that has made us question its use for coating battery terminals and cable lugs. We just installed a bank of HUPs on Monday using Quick Cote. First we lost power with just the Trimetric and MX60 powered up -- using an ohmmeter I found the problem to be a single jumper -- I got 7 megohms across two battery terminals connected by a jumper -- so I replaced the jumper and got the Trimet and MX60 powered up again. Then, when I powered up the OutBack inverters, there were sparks on the battery terminals, and the power cut out again. At that point I guessed that the problem must lie with the Quick Cote, since ours has tiny crystals in it (it feels gritty), and I thought those crystals must be holding the cable lugs off the battery terminals a tiny bit. Sure enough, Mark and I took the cables off, wiped off the Quick Cote from the contact surfaces and applied vaseline, and when we powered up the system, no sparks. (So, the jumper I removed probably wasn't to blame for the first loss of power.) Our container of Quick Cote stayed on the truck (which stays parked outside) during the seriously cold weather we got this winter, so it probably froze. I'm guessing that's when the crystals formed. Nowhere on the Quick Cote label does it say to keep it from freezing though. We're going to go back out to another job to wipe off the Quick Cote from the contact surfaces of the battery terminals and cable lugs, since we just installed four new batteries there and used Quick Cote, and I remember it being gritty at that time as well. Is your Quick Cote gritty? Russ I told Russ that it always has been gritty. When it's dried out in the can (they often leak), I have added an oil-based carrier to thin it - usually WD40, as it's on the truck - and it's always mixed easily. So it's definitely solvent-based and shouldn't be affected by freezing. I haven't had this problem before. I have found terminal bolts too loose and that has caused failures, but never the coating.

Re: [RE-wrenches] 100 Foot Skystream tower
Dana, Could you tell me a bit more about that 100' tower? The last I knew, SWWP only offered a 70' tower. So this would be a 3rd party tower? Xzeres (formerly ARE)? Or LMWS? And is that schedule 40 pipe or schedule 10? Did you install the concrete foundations? Since you've installed some tilt towers before, I would imagine you understand the importance of having the foundations line up correctly. For this reason, I hate finishing a tower installation someone else started! I've seen as much as a 6 foot difference in elevation between the two side anchors on owner installed foundations. Under ideal circumstances and on that mythical frictionless plane, I'd allot 1 day with 3 people for assembly and another day with 4 people during the initial raising of the empty tower and the final raising with the cherry on top. Having a side spotter on these towers is invaluable!

Joel, I would be very interested in further updates on your Envi experience. I bought one to use in my PV installer workshops and used it for the first time back in May.

The SunnyBoyinverter is next to the electric service panel. Grid powerwiring intothe service panelis behind the clamped and sealed utility meter. I did not want tobreak the utility sealto open that section of the panel so I am not monitoring the grid.Besides, monitoring the grid with anet meteredPV systemonlytells whatthe utility kWh meter measures.

Re: [RE-wrenches] TED MONITORING

One small office was completely unable to transmit MTU-gateway signals. TED tech support just blamed it on interference from fluorescent lights and UPS systems. I would say their tech support leaves a lot to be desired, although it is easy to get them on the line. I just think the product is inherently problematic, and there is not much they can do to assist. We were unable to isolate any circuits that were causing the interference. The same unit worked perfectly at another location. On a larger home, it took hours of trial and error to find a suitable gateway location (especially given that it needs to be close to a LAN connection). It's really hard to sell a product when you have to tell customers that it may or may not work in their home/business. And wasting time trying it, only to fail is time/money spent. We have been evaluating the Envi as an alternative. It is completely wireless and can monitor up to 9 circuits with the same base. The web interface is not as robust, and the MTUs are insanely huge, but it does have many advantages (and it costs less). The Google Powermeter is pretty lame. It does not provide the granularity that we need to make useful analyses. Hopefully they update and improve the product. Finally, I am not convinced about the accuracy of any of these devices. Under normal conditions, the Envi seems to read low, the TED seems to read high. At very low current, the opposite is true. Each one seems to have a sweet spot for accuracy.

Re: [RE-wrenches] Thermal isolation (and liner) for battery bank
I use the same technique as Dana just mentioned and it does work very well. The blue rigid insulation we call Dow board has a very high compression strength. It's used under concrete pads and between house foundation walls and the backfill with great success. Good enough for batteries. What I haven't seen mentioned here is the material I've touted several times on this list since '99 called Structoglas. This is a very heavy duty fiberglass sheeting that is used in kitchens, restrooms, dairy milk parlors, etc. We've been using it since '98 to line the interior of our plywood battery enclosures. We make the bottom liner out of a single piece, no seams. We install an 8" high vertical "base trim" strip on all 4 sides and seal it with a high quality, 50 year silicon caulk. 12 years now, with several acid "incidents" caused by a few of our less maintenance conscious customers, have proven to us that the fiberglass and the caulking hold up perfectly. I'm off grid here and have been able to observe my Structoglas liner for 14 years. No degradation whatsoever. Don't tell anybody but I've done some acid testing here myself ;-) The nice thing is that this is available at most Lowes and Home Despot stores. A 4 x 8 sheet is usually around $34.00. One sheet will easily do an enclosure that holds 12- L16s. It cuts easily on the table saw and can be scored and snapped as well.

Re: [RE-wrenches] Lorentz Sub Pump
I've had the worst time with those CU200 controllers as well. The only reason I use them at all is for the float switch function. Many of our agricultural installations have long wire runs between the tank/float and the controller, so we really have no other choice than to use the CU200. Out of the last 32 SQ Flex installations we've only had one bad pump and thankfully, that was an infant mortality case and covered under warranty. And yes, customer service at Grundfos is horrible. About as bad as their documentation! Like many of you, I was burned horribly with the Regretta pump linemany bad pumps and even more bad controllers. I dropped them like a hot potato and have used the Grundfos SQ ever since. It's definitely not perfect but it's better than the old versions of the Eta/ Regretta. Like Allan said, it was a tough decision to drop that pump line because I like Windy Dankoff and wanted to support Dankoff Solar. His company had a heart when he was running it and I really miss that old fashioned quality customer service! I figure he was stuck in the middle of the Eta debacle like I was, so no hard feelings. We still love ya Windy! I'm following this thread with great interest. If the Lorentz pump has indeed improved, I want to know all about it. Thanks for all the great info!

Re: [RE-wrenches] Lorentz Sub Pump
Hi Jeff, I probably should mentioned that many of our float switch wire runs exceed 3,000 feet from tank to Cu200. We use shielded, direct burial rated 18/2 cable, bury the wire and ground the drain wire at the controller. So with those long distance systems, do you think a relay would work? It just doesn't seem feasible to run coil voltage that far. That's why we've been relying on the CU-200 microprocessor to do the job. Also, I don't like to run anything but the pump off a PV direct system. As for the pressure tank/ switch option, we do have a few of those out there and I agree, they work fine. But on some of our systems the vertical rise between the pump and storage tank is over 300 feet. That's about 130 psi and those pressure tanks wouldn't like that too much. And for various design reasons, a check valve on the main feed line isn't feasible, so we ruled out the pressure switch option on these long distance systems. I also like to keep things as simple as possible where livestock water is concerned. Farmers have so many maintenance items on their list now, I hate to add more. So at first look, the Cu200 seemed to be the ticket. Thanks for the info!

This works at any distance w/o control wires and is fully hydraulic and highly reliable plus this valve does not throttle as it reaches full.

Re: [RE-wrenches] Pump choice - Grundfos or Lorentz; distributers of Lorentz
I have 11 Lorentz systems in the field. The biggest problems I had were with the controller. Infant mortality, failure within the first 3 months and the float switch circuit failing were some of the issues. I also ran into the rubber problem that Windy mentioned. So I switched to Grundfos. 16 of those in the field now. I've had a lot of trouble with the CU200 controller. The dreaded F4 fault is the worst. The controller loses communication with the pump. I had a bad batch of CU200s that had faulty modems but got those replaced under warranty. I've had 2 pumps with bad modems as well. Sometimes the pump won't run at all with an F4 fault, but most times it will. But the pump is stuck on the setting it was in when the comm failed and performance isn't usually very good. Even with these problems, I still prefer the Grundfos system. I love the flexible input voltage. It gave me the flexibility to adapt the array when module availability was hit or miss. As for customer supportwhen Dankoff Solar was handling their version of the Lorentz pump known as the ETA pump (aka the Regretta pump!) the customer service was phenomenal. With Conergy, not so good. I'm still underwhelmed by the Grundfos factory support. They would rather have the pump distributors handle all the warranty issues. When I need to contact Grundfos directly, I get the distinct feeling that I'm inconveniencing them. I'm installing 5 more Grundfos systems this spring. Maybe all will be goodness and light this time ;-) And Windy.really glad to see you back in the game for a bit. I've missed you my friend!

Re: [RE-wrenches] Battery Automatic Watering
Joel, I was waiting to see if others use my method but I didn't see anyone post it. I've been off grid and having to maintain my batteries since 1997. I grew to hate the battery watering jugs for several reasons and finally came up with something that works for me.your results may vary! I now use a pump up type garden sprayer. I use a 1.5 gallon version with a plastic wand, spray tip removed. I pump it up 6-8 times and that pressure allows me to fill 3 to 4 cells, depending on the volume of water needed. What I like about this is that the wand reaches anywhere in the bank and most important, I can watch the cells fill. I put a piece of electrical tape around the wand and insert the wand into the cell to the tape level. This is my water level and it's really easy to tell when the electrolyte reaches the end of the wand. About 1/2 of my customers are off grid and most use the sprayer method with good results.

Given the ratio of PV vs battery capacity, I would suspect that their batteries have been chronically undercharged for ages. We usually recommend around 1 watt of pvper AH for a 12 volt system, 2 watts for 24 volt etc. A generator is not usually the answer, because it may have to run for hours to get that final 5-15% of charge into the batteries.

Re: [RE-wrenches] Helix Wind
Keith, Feedback on these and other VAWTS? Oh, you bet! Bottom linethere are no commercially viable VAWTS on the market today. Only lots of spinny things we call kinetic lawn art. To be more precisemost will generate power but almost none are able to generate energy in an efficient, cost effective manner. Especially on a rooftop or near the ground where the VAWT marketing promotes their installation. And if you read further about Helix, they just agreed to acquire all assets of Abundant Renewable Energy...the makers of the ARE 110 and 442. It appears that the VAWT people have caught on to the fact that HAWTS are where the money is. That's not to say that there's not a lot of crappy HAWTS out there... but that's a story for another time ;-) I'm not against VAWTS, just deceptive marketing and scams.

We have installed 6, the oldest one being in operation for about 14 months. One is part of a battery based grid-tie system, and operated well when tested. One of the turbines is in world-class wind in Southeast Wyoming. I just checked with the owner and it produced about 480 kWh in the last month on a short tower (with a hundred miles of sagebrush to the windward side) at almost 6000 ft elevation. Unfortunately this turbine doesnt have an anemometer/data logger, so we dont know if it is performing as expected. My guess is that it spends a lot of time self-regulating. One of the turbines was in the recent batch of recalls and was dealt with by a SWWP-hired contractor. This involved a potential leak in a seal of the electronics compartment in the nacelle (although for some reason they are replacing the whole turbine). While reaching somebody at SWWP tech support has been nearly impossible, this turbine swap was handled fairly swiftly. From the others experience, sounds like we should keep our fingers crossed. P.
