Re: [RE-wrenches] Magnum System - Discharged Battery Bank

[RE-wrenches] LBX with Magnum?
Greetings, I'm trying to set up a magnum inverter to reconnect after a low battery cut out condition at a higher voltage than is presently set. Basically like the old SW inverters LBX mode. Magnum tech-support thought using the advanced remote control can work but I'm not seeing that adjustable setting in any of the menus. I would call it low battery cut in. There is no AC input to this inverter so we want the batteries to recharge with the PV system until it gets to a higher voltage, say 55 V before the inverter turns back on. We also have a midnight charge controller on board but I'm trying to use the inverter features first.

Since the inverter output OCPD is required to be 60A we are looking at a supply side connection, and I have two questions: 1. Before the point of interconnection the inverter output circuit will first pass through the XW Power Distribution Panel and inverter bypass, which is essentially a 60A breaker. The service disconnect for the supply side connection will also be fused at 60A. Does the 120% rule apply to the conductor between these two OCPDs?

Jeremy All Solar - Original Message - From: Allan Sindelar To: RE-wrenches Sent: Thursday, January 24, 2013 12:35 PM Subject: [RE-wrenches] 24V Module Query Wrenches, We have years of installing 36-cell (12V) and 72-cell (24V) modules for battery-based customers. Most of our systems are 24V or 48V nominal. Over the last few years, sources of conventionally-sized 72-cell modules have dried up - as cells have increased in size, most modules and most newer factory production lines have either gone to 60-cell (20V) modules, or 72 cells in 300+ watt ranges. It seems that the formerly common 72 cell, 24V modules in the 150-190 watt range, which are well-suited to integrating into existing systems, are no longer available. 60-cell modules in the common 220-250 watt range can't be added to an existing system unless run through a dedicated MPPT charge controller that can convert voltage, such as an FM, XW60, Classic or TriStar; the added cost of any of these controllers cancels out the low prices of the modules. Who continues to manufacture 72-cell modules? Which distributors carry them? I am aware of three options - are there more? - Sunpower makes one module in the 245 watt range that can be used negative ground, but it's very high efficiency (and with high Voc/Vmp as well) and very pricey; - Sanyo/Panasonic has 225-240 watt modules, but also quite premium and pricey; - Ameresco bought the rights to manufacture many former BP modules, and I think they make some. But we had to replace lots of failed BP modules in that size range, and are hesitant to use their technology, fearing that the problems may persist in the continued line.

[RE-wrenches] Trace Parts - colorado
Hello Does anyone know if the One Stop Cop shop in Colorado Springs still repairs inverters? I just spoke with a client who may need an AC board for an SW. Maybe best to just upgrade him to an OB! The SW will start the genny automatically, but he must stop it manually. (AC board has the relays correct?). He has an Onan genset, which sounds like it may be 3 Or 4 wire start. Also thought of maybe a Solar Converters auto gen start module or equivelant so he could still use the inverter, as is. Any recommendations would be helpful.

Re: [RE-wrenches] Magnum MS 4448 AE issues
We have installed 3 Systreams in off grid settings with the Whisper 500 DC dump load (from SWWP) with good results. Used 2 Morningstar TS 60's, one set a little lower, as a secondary diversion (per code) in case the other fails. I have an SW Plus set up this way at our office, and the others use VFX inverters. All with OB transformers and the Skystream AC coupled of course. DC dumping with the Tristar is modulated and does not affect the AC at all. My Skystream has been modified by SWWP to reduce the 5 min. delay to about 30 seconds, but they do not want to change the others. This is ok if you have PV as well.

I would preface the following with the information that he is a very knowledgeable/hands on physicist (chair of the Physics department at Dalhousie U. in Halifax, as well as an intrepid sailor having sailed all over the world in 2 different sailboats he built himself). I mention this to explain that he is very capable and understands the inner workings of his equipment much better than most wrenches I know (and certainly me). About a year ago he installed a SkyStream 3.7 to add to the roughly 3 kW of solar on an FM80, and then a short time later disconnected himself from the grid. He immediately started having problems with the Skystream regularly disconnecting from his system and shutting down, then reconnecting and cycling off again, were as there hadn't been a problem while grid-tied. After much investigation and conversation with SW WindPower tech support and some software patches from them, things improved somewhat. But the regular disconnections continued. Since then he has spent a great deal of time on the phone with Magnum's tech support but they have not been able to answer his more technical questions. The best they've offered is to have him send the inverter in, but of course that is now not practical. The basic problem seems to be the voltage regulation during loading and unloading of the inverter (even with medium sized loads). He tried to get an internal wiring diagram and/or service manual from Magnum with no luck. He has not been able to get through to any engineers that would be able to answer his more technical questions. He is trying to figure out if there are any internal set points that he can adjust or components that can use tweaking. He has looked at the wave form with a scope and would like to see if there are changes that he can make to the electronics to allow for better regulation. Here is what he has written me: "Here is my report on the Magnum MS4448AE observing the AC output with a Fluke 189, measuring the max and min values in slow mode (not it's fast mode which would look at spikes for short times): I have checked several water heater elements running on 240 V (they are between 2000 and 2500 Watts - immersion heaters). When switching any one of them on, the voltage drops from around 240V to 197 V on average, sometimes going as low as 170 V. These are serious drops, the lights dim drastically and the radio may cut out for .5 s or so! Switching the thermal heaters off again raise the output voltage to 271 V sometimes reaching 282 V. The battery bank during those test were at 53 V at the DC input side of the inverter, measured at the inverter. The voltage drop for the DC was around 1 V DC. The battery bank is a 800 AH (Rolls S530) with 2/0 copper cables 5 - 6 ft inverter cables. We had great wind yesterday and I had to switch to the hock up the diversion load to 240 V so it would draw 2.5 kW. Needless to say it stalled the windmill each time my outback kicked on the diversion load. I had to leave the windmill off during the day. When I run the heating element on 120 V (and therefore 625 W) it works beautiful if the wind isn't too strong. Obviously the inverter handles 625 W quite well!" He is also thinking about replacing the inverter with a newer split phase inverter (an XW or a Radian). If anyone has an opinion about which might work for him, I'd appreciate any feedback. I am not a fan of Xantrex, although I know some on the list really like the XW. If anyone has any ideas of either a fix or someone we can get through to at Magnum, that would be a great help.

[RE-wrenches] 48 VDC timer
Anyone know of a reliable 48vdc timer to control a well pump? Pump will be a Grundfos SQ 240VAC. The idea is to limit the run time to prevent over discharge of the battery bank. The only charging source for now will be wind power, and the wind gen requires AC voltage to connect. I'm concerned that the batteries may discharge, inverter (VFX 3648) shut down, and we loose input from the turbine. May be something else that works too. Right ??

This may be the more informal interpretation of the term, but you will find many examples where people consider C/20 to be 5% of the capacity (wrong or right). For example, look at the most frequently accessed deep cycle charging FAQ on the Internet: http://www.windsun.com/Batteries/Battery_FAQ.htm To be clear perhaps we should just use plain English and say “the recommended charging rate is 10-15% of the capacity of the battery at the 20 hour discharge rate.” Jason Szumlanski Fafco Solar From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Allan Sindelar Sent: Monday, April 02, 2012 1:46 PM To: re-wrenches@lists.re-wrenches.org Subject: Re: [RE-wrenches] Hot Trojan Batteries Wrenches, I attended John DeBoever's Friday afternoon presentation on battery technology and care at the NABCEP Continuing Education conference this past weekend.

The first thing John told us was that English is not his native language; he's a Belgian raised in South Africa (and more that I didn't catch). He was bursting with knowledge and good information, but occasionally we in his class would back him up to better explain a point. In short, I think he will be a real asset to the Wrenches list as a manufacturer's representative. And occasionally there will be something confusing, such as what just happened here.

You could almost run a 22 v nominal system, if you used 2 v cells. Charge
controllers like the FM60 and the Classic have enough adjustment in the bulk/
float settings to make it work, and that would be closer to the 20 - 28 v dc
window you're looking for. (20 v would be comparable to 10.9 on a 12 v system
or complete discharge, while 28v would be 15.3 v on a 12v system, plenty of
room to EQ)
However there are a lot of comm systems that have been running off grid for
decades, so I really think you just need to take another look at the required
specs. Solar Converters in Canada make a voltage regulator that will stabilize
a battery voltage, as well as up and down DC to DC converters.
Also, I'm up in Denver, and don't mind driving (buy my gas) if you ever need
any help.

Re: [RE-wrenches] Kohler Generator Issues
Jeff, check out Gillette Generators. Prime power warranty. and 'ok with inverter' Jeremy - Original Message - From: "Jeff Yago" To: "RE-wrenches" Sent: Monday, March 29, 2010 8:53 AM Subject: Re: [RE-wrenches] Kohler Generator Issues Although we have specified and included Kohler RES models in all our off-grid and battery based solar projects for over 15 years, we have seen a real decline in the suitability of the Kohler line in the past few years for use in solar/battery/generator applications. First they killed off the 1800 RPM units under 15 kW. We had many older systems that would not work when we replaced an aging 1800 RPM unit with their same kW size new 3600 RPM units, which made inverters go nuts with under-voltage and over-current errors. Then several years ago they got rid of the battery charging alternator or whatever that re-charged the battery when the generator was running as a way to reduce costs, so now the only way to keep the battery charged was to plug in a full time float charger. This 24/7 electrical load is not a good idea for smaller off-grid systems and requires another set of wires out to the generator to supply this outlet. Finally, Kohler added a diagnostic electronics panel that adds another 24/7 electrical load. We "kill" this off during installation on any off-grid application as we cannot justify this 24/7 standby load. There is a software switch to do this, but its not easy to find in the instructions. Funny thing was the other day I received a call from the main Kohler factory about some marketing issues and I finally let loose with the above rant. I really complained that so far they have done everything they could NOT to serve this very large and growing off-grid market, and I pointed out that most of their recent design "improvements" made their generators LESS suitable for this market, not better. This guy was absolutely dumb-struck, and it appears to me that they have made no effort to understand this market. Their more recent efforts to void warranties is just another reason to look for a different generator supplier. Has anyone on this list had any contact from Kohler central office about finding out what features this industry needs? The guy I talked with may be just blowing smoke, but he promised to have a followup call in next few weeks to learn more about what they can do. According to him, he thinks they can add a software "switch" in the programming for little or no cost like "on/grid - off/grid" that we could access during setup that would adjust generator parameters and standby losses when used in an inverter-battery application. In case he really does followup, are there any other rants I could include from you guys that have been a problem for you when using Kohler generators. I will assume we are limiting this to their non-water cooled units under 15 kW. While ranting on generators, the main reason we liked to use Kohler was the easy 2-wire start/stop connections you can connect to the aux relay in most inverters, while many other generator brands were not easy to remote start from an inverter or required multi-step starting relays. Has this changed, and are there now other brands of generators in the 8 to 15 kW range that work well for backup of solar/battery charging applications and the manufacturer does not have warranty issues when used in off-grid applications?

If you have 120/208 you have WYE. How much power do you have to put into
the grid? The question if you need back up power what is it for? if it
is simple plug loads or lighting you might serve the customer well with
single phase backup. If you need 3-phase back-up I find it hard to accept
that they need it in one box. The Xantrex is three seperate inverters on
one board that looks like 1 box. The three 120 volt units make 120/208
three phase. If you have 120/240 three phase you have Delta, high leg.
Other combinations of three phase are possible, but more rare.
I am old and I have never seen a problem of 3 phase imbalance if I stay
within 20% of the panel rating. In fact I have seen single phase loads
that will imbalance more than 20% not cause a problem. The problem of
imbalance is similar to what occurs with single phase and changed inverter
rules to requireing a ground reference on 240 volt inverters. This
problem is that the neutral will get pushed off center voltage wise, I
usually demonstrate this in my class. YOu can not cause significat
imbalance with three 120 volt inverters, but you could woty the old 208 no
neutral inverters.

Could you not just use one 120V inverter? I've
connected single 120 volt
inverters (albeit not outback but I don't see why
not) to a 120/208 wye
without problems. You have to make sure the wires are

Use 3 of their 120 volt

3 phase. Each
inverter is only a single phase, and you connect each
inverter to the
neutral and one phase, you program one to be the
Master, and the others to
be slaves on phase B and Phase C. When you lose
the grid, the Master
inverter starts its sine wave and it generates the
usual 60 Hz square wave
on the Outback Bus and the following slave units delays
the start of their
sin waves by the appropriate 120 degrees to generate 3
phases. Each
inverter picks up and makes 60 hz 3 phase.
One thing, besure to get
a rotation meter and check that you are generating
3-phase the same rotation
as the grid. Else you will have big problems. (motors

[RE-wrenches] 3 Phase Grid Tie with Battery Backup
Anyone know of a system for Battery Backup that can also be grid tied for 3 phase? Our local Utilitly Co. wants system voltage to match service voltage. Thanks in advance!

WOW. That a lot of info. I couldn't even read it all. :) - Original Message - From: Antony Tersol To: gilliga...@gmail.com ; RE Marketing for home scale RE industry Cc: RE-wrenches Sent: Thursday, February 11, 2010 2:47 PM Subject: Re: [RE-wrenches] [RE Marketing] sales commissions Every once in a while, there's a posting that's worth saving. This one goes in the "Organizing your business" folder. Thanks Matt. With this much wisdom available for free, what could I get if I bought you lunch and a beer? On Thu, Feb 11, 2010 at 1:11 PM, Matt Lafferty wrote: Is it OK to be chicken sh#$ with salespeople who are full of bull sh#$ ? I don't know if this qualifies as the "wisdom" you were asking for, Marco, but here's my take on the topic: I am in favor of being fair and supportive with employees. To a fault. Outside salespeople are different animals and may need to be treated differently than other employees. More often than not, in my experience, outside salespeople with commission-based compensation are the biggest "Me First" SOBs in the business... Regardless of whatever business or industry it is. If they are a Pure Salesperson, they came from another industry where they had the same attitudes and practices. They do whatever it takes to get their commissions and they snake around in any manner possible to ensure somebody else deals with all the headaches they cause. A commissioned salesperson is a hired gun by nature. Quite often they have little to no loyalty to the employer or the customer. If things get slow or they're not making the $$$ they thought they would, or they simply get bored, they move on. But not before they get everything they can from you. If you (the employer) are paying for their cell phone, 3G wireless, car, laptop, etc., they will use all of them in their quest to find their next job. Seen it happen more than once. I can think of precious few individuals who are the exception. That being said, I still believe in treating them fairly and honestly. After all, these are the folks who get your company in the door with your customers. They would tell you that you don't have a business if not for them. Depending on your business model, this may be true to some extent. It may also be completely untrue and, if it is, you need to adjust their attitude. In answer to Marco's question about commission payments for expansion projects, I believe several factors come into play... Some of which have been mentioned by others and some have not. For the edification of Mainlanders, I think it is important to understand that Hawaii's current incentive structure favors expansion of PV systems over multiple years. Year One plus Year Two systems equal a total project. Asking the question of how best to deal with commissions in this environment is fundamentally different from asking it in other regions. Keep that in the back of your head. For the purpose of general evaluation, regardless of the region, I would first address the question by asking if this is an infrequent situation vs. one which is common or expected to be common? In the case of the Aloha state, I would check the "common" box. This creates the need for a company policy on the matter vs. dealing with it on a case-by-case basis. In areas where actual future expansion is rare, I'd say the salesperson's compensation should be what it always is. If your company did the original installation, I might even recommend an extra spiff. Times are tight. Going back and mining your existing customer base is good business. So Let's make a Company Policy. Since it appears that commission-based-on-actual-project-profitability is not what we're doing, we need to address three scenarios: Scenario 1: Your company did not do the original install. Scenario 2: Your company did the original install and this salesperson is the orginal salesperson. Scenario 3: Your company did the original install and this salesperson was not the original salesperson. Scenario 1 is easy. They deserve full pop. Pay them like it was a stand-alone job at whatever kW you're selling. Doesn't matter if they were the original salesperson or not. If they were the original salesperson, buy 'em a beer, too. Then tell them to get back out there and keep bringing in their old boss' customers! (Note of caution: In Scenario 1, pay close attention to the job costs and adjust your prices upward if needed. When calculating job costs, be sure to include a number that covers warranty and service reserves. Following others onto a jobsite has potential downsides!) The other two scenarios require a look at the actual compensation structure and what the salesperson actually does for their paycheck. If less than 50%
