Re: [RE-wrenches] Hawker versusu MK

[Ray Walters]

We use a high lift jack to lift the case up onto a carrier we've made. 
Roll them right into the room. We then use the high lift to push them 
exactly into place, with a wood brace against the wall. I'm still a HUP 
fan fro the cycle life (2100 cycle to 80% DOD) but if the 1500 cycle 
batteries are 30% cheaper, then they're the better deal ( not counting 
the cost of  moving batteries sooner)
I will third the Rolls problems; we had a reversed cell that we were 
shipped new.  A guy with a multimeter at the loading dock could prevent 
these dead ducks from flying.  The customer was out of power for 6 weeks 
waiting for the replacement,  while we paid $200 shipping.  For the 
money vs. cycle life vs. warranty, we just weren't loving the Rolls.  
They are easier to move, which is a good thing, but HUP pays shipping 
and for your time for the first year.

Interesting to hear the comments on the Rolls shipping.  I've seen that problem

If I remember correctly, the steel cans had welded seams. The cans make the use

Speaking of replacing cells. I looked at a 5 year old bank of 8 Rolls L16s this
weekend. Two of the batteries had a dead cell. This in a bank that had a single
battery replaced at 6 months or less because of a bad cell.

I've also got a 7 year old bank of 12 Surrette / Rolls 2 Volt units installed.
The only problem so far was on day one when they arrived. They were shipped on a
single, narrow, beat up pallet. Some had obviously tipped over in transit and
had lost a considerable amount of electrolyte. Northern Arizona Wind & Sun
user's forum has posts reporting similar experiences.

I dread receiving expensive pallets of batteries and modules from shippers. High
percentage of damage. Steel cans instead of plastic wrap is worth thinking
about.
Hope this doesn't just muddy the water.

Re: [RE-wrenches] Question re Midnite surge arrestors

[Allan Sindelar]

  
  
Ryan,
  I may have found the answer to my original post, but it raises
  more questions. 
  
  I wrote that these were MV units (MNSPD300), but I checked with my
  lead tech and learned that in both cases he used LV units
  (MNSPD115). Could this be the reason? He told me that he has used
  the LV with 120V inverters and the MV with 120/240V inverters. The
  instruction manual states that the LV units are designed to be
  used on nominal 90VAC and 115VDC circuits, and have a Maximum
  Continuous Operating Voltage of 180V. The manual states: "The
  MidNite Solar SPD voltage rating should be chosen according to the
  nominal voltage of the system. Do not install an SPD with Maximum
  Continuous Operating Voltage (MCOV) below the nominal voltage of
  the system; this will deteriorate the SPD and making it
  unavailable when you most need it." If this is true, then the LV
  (with its 180 MCOV) should be fine at 120VAC. The instructions are
  confusing: should we use an MNSPD115 or an MNSPD300 with 120VAC
  output? And in this case, could this be the cause of the
  failure-to-sleep problem?
  
  If we should be using the MNSPD300 with 120VAC inverter output,
  then the description on the Midnite website is confusing at best.
  It states that the MNSPD115 "is designed for both AC and DC
  systems and provides protection to service panels, load centers or
  where the SPD is directly connected to the electronic device
  requiring protection." But service panels and load centers seldom
  if ever carry AC at less than 90VAC, the nominal rating of the
  MNSPD115. Please clarify all of this!
  
  Thanks, Allan

Wrenches,
Very seldom do inverters in off grid systems ever go to sleep
anymore, given the increase in phantom electronic loads and
greater customer expectations. Coupled with lower module prices,
we usually size larger arrays and inverters remain on
continuously. However, we also service and upgrade many existing
systems, and some customers still want their inverters to go
into search mode. They typically either have gotten used to a
more energy frugal lifestyle over many years, or (to their
credit) choose to buck the system and live with a lighter energy
and resource footprint. 

Twice in recent months we have added Midnite MNSPD MV surge
arrestors to the AC output of smaller systems and discovered
that the inverters will no longer go into search mode. It
doesn't appear to make any difference where the search watts
threshhold is set. One system used a 24V Outback FX2524T (with
current boards following a nearby lightning strike) and the
other used a Magnum MS2812. In the former case, we defeated the
search (against the customer's preference, as she liked the
total silence once her day was done). In the latter, the
customer rejected and we removed the surge arrestor once it
became clear that the inverter wouldn't sleep.

Has anyone else experienced this? Is there a fix for it? Robin,
can you chime in here (off list if necessary; I'll carefully
post your response)?

Re: [RE-wrenches] Hawker versusu MK

[Kirpal Khalsa]

William.we have used a set of industrial flooded lead acid batteries
made by a company called Storage Battery Systems (www.sbs*battery*.com)The
batteries are 2V batteries with 3200Ah capacityThey come with a variety
of warranty options. Our client decided on the 20 year option (5 years
full, 15years prorated)  They have a clear case so you can easily with just
a glance see the level of the electrolyte.They have tubular plates and
came with all the interconnects which cover any exposed metal at the
terminals once they are hooked up.. except a small hole to insert your
voltmeter leadsThey have 4 terminals on each battery so if you need to
run multiple homerun cables you have plenty of plenty of options with out
having to double lug your battery cables on a single terminal. They have
been in operation for almost 4years now without so much as showing any hint
of wear.While they are expensive they also offer extras such as seismic
racking, spill containment systems, and hydrogen gas level alarms.  The
feeling that i got from this company is that they are more in the
industrial battery market and not so much the renewable energy
marketThey are worth a look.we are really happy with their
product

More frequently though we use the Rolls Surrette series 5000
batteries...They also have been reliablewe once had a reverse polarity
from the factory so check polarity of each battery before hooking them
up.These are our main go to batteries when a larger than 800ish Ah
battery bank is called for.  Trojan also has their newer line of industrial
batteriesWe have used them a couple timeswarranty is not as good as
the Rollsbut they have the dual cases like the rolls and seemed like
good batteriesBoth the Trojan and Rolls are supplied with string
interconnects(make sure to remind your distributor)
We have had to train our distributor to supply good quality stainless bolts
(with sufficient length) with lock washers and washers with all battery
purchases
Good luck...

[RE-wrenches] Hawker versusu MK

[frenergy]

Here's a third for 2V Surrette's... However you should discuss details 
with this list or someone at Surrette regarding your application.  For an 
example, Solar Power source? C/rate? Are you replacing a set of golf cart 
batts or batteries with similar charging needs as these large cells?  The 2V 
1766AH cells seem to prefer being charged longer and slower than say a T-105 
or an L-16 to ensure proper SG's (others please chime in hear with 
similar/different experiences).


   Yes, being easier to move is great...a handtruck or 2 bodies works 
perfect.  Dual container simplifies your battery box AND keeping the tops 
clean. The large/tall area above the plates means less watering.


   One warning though is insist on getting all the cells from one 
batch.  If your supplier has to wait for cells from some other distributor 
to make up your pack, ask to wait for all cells to come from one production 
batch.


   I know a lot of folks have and love metal cased 12V "packs" (I'm 
still working one myself) but I won't be going that route again for a

I install large battery banks ALL the time. We DO NOT use any battery 
that

is incased in a metal enclosure.
REAL pain to move, cells DO go bad & when they do its a real pain to 
bring

the engine hoist to remove them. Hard to keep the cases from leaking &
rusting.
We DO use the Surrette 2 volt cells in the dual container exclusively.
These are rated as a "containment vessel", & much easier to move. In the
event when a cell does go bad, use a jumper to bypass the bad cell,
operate w/ a lower LBCO setting leave the CC settings the same, while
waiting for replacement.
1700 AH -2400 AH.
By the time you have the tractor/back hoe on site, my 2 volt cells are up
n running! E mail me off list and I can give you a few tricks to move
them.

[jay peltz]

I agree with Daryl and Tump

And would add Trojan IND as an option to the Rolls and made in SoCal

Also most of the industrial battery folks make 2v cells.
