[RE-wrenches] Hawker versusu MK

2013-08-13 Thread William Miller
Friends:
 
We are shopping for industrial, flooded, lead acid batteries.  We are
considering 12 volt packages in the 1800 AH range.  Under consideration are:
 
Hawker 12-25W-23S at 1705 AH or MK 106M1033STB at 1896 AH.
 
Have any of you had experience with either, or recommend another option?
 
As always, I am extremely grateful to all of you for the limitless wisdom
offered.
 
Sinceerly,

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

[RE-wrenches] Hawker versusu MK

2013-08-13 Thread 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 
variety of reasons.  It's a big investment, do your homework.


there's 2 more cents worth.

Re: [RE-wrenches] Hawker versusu MK

2013-08-13 Thread 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: [RE-wrenches] Hawker versusu MK

2013-08-13 Thread Richard L Ratico
I've got two Hawker installs out here, a 48 Volt and a 24 Volt system. Both are
going on 6 years or so. Clients are happy, I'm happy. It does resemble work to
move and place them. We typically use Egyptian techniques when heavy equipment
isn't available or appropriate. Inclined plane, big pry bars, rollers, come
along, block  tackle. It's kind of fun to try to outsmart the mass. It's
interesting to experience gravity's effect on lead, atomic weight 207.2. Glad
it's not Uranium at 238. Thankfully, we've not had to replace a cell. That
always sucks, regardless.

If I remember correctly, the steel cans had welded seams. The cans make the use
of insulated tools even more important. Should you ground the cans???

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-wrenches] Question re Midnite surge arrestors

2013-08-13 Thread Allan Sindelar

  
  
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)?

Thank you,
Allan

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

2013-08-13 Thread 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

  That is not expected behavior. Which model of SPD are you using?

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)?

Thank you,
Allan

Re: [RE-wrenches] Hawker versusu MK

2013-08-13 Thread jay peltz
Hi Dick,

Best trick I ever learned for these metal cased is to build  a 
wheeled base with steel wheels.  
Yea, still have to get them onto the base, but then its easy.

Also when I  use metal cased batteries I like to have them with removable 
series interconnects
not the welded type. 

Interesting to hear the comments on the Rolls shipping.  I've seen that problem 
myself, but 
didn't realize that it was so common.

 I've got two Hawker installs out here, a 48 Volt and a 24 Volt system. Both 
 are
 going on 6 years or so. Clients are happy, I'm happy. It does resemble work to
 move and place them. We typically use Egyptian techniques when heavy 
 equipment
 isn't available or appropriate. Inclined plane, big pry bars, rollers, come
 along, block  tackle. It's kind of fun to try to outsmart the mass. It's
 interesting to experience gravity's effect on lead, atomic weight 207.2. Glad
 it's not Uranium at 238. Thankfully, we've not had to replace a cell. That
 always sucks, regardless.
 
 If I remember correctly, the steel cans had welded seams. The cans make the 
 use
 of insulated tools even more important. Should you ground the cans???
 
 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.
