off-brand T-105s in six strings of 4) with nice new set of AGMs (3 strings of
4). It has a solar array and Whisperer 200 turbine charging the bank and
no generator. Customer says the old batteries which are pretty worn, were
always boiling and losing water. I tested all the cells with a hydrometer
on my last visit and found no obviously dead cells but all of them seemed week
with some visual sulfation. I am thinking the bad batteries are
most likely the culprit, but I would like some ideas on what and how to test
both the C40 and Whisper controller to make sure they were not causing the
overcharging. Any ideas on what tests to perform? <o:p></o:p></span></font></p>

Give her sealed batteries for this application. We like Concorde SunXtender,
both because the few sets that have been in operation off grid have shown
exceptional life (we have one series pair of PVX-2580Ts going into its 13th
year still in good shape) and are available in sizes that easily replace
standard flooded sizes. Contact me off list for a good distributor referral.<br>
<br>
If indeed they have "abused the batteries to death" then the
batteries are indeed dead. I'd suggest that you sell her replacement sealed
batteries. They'll arrive charged. Thus during daytime you can use the array
itself and the full batteries to test the C-40, and set proper regulation
voltage at the same time. Save the customer a second service call, make you a
decent sale, worth the trip.<br>

Just my $.02001 <br>

style='font-size:11.0pt'>A client has an old school 12VDC remote cabin,
(SunDanzer fridge, Sureflo pump, 12VDC lights and fans) which she visits
perhaps every three months. It isn’t her interest to clean terminals,
much less run the generator through one of her two days of country quiet to
equalize the battery bank. The consequence is that she (and guests who borrowed
the cabin) have abused the batteries to death. The first suggestion will be a
maintenance agreement…yes. First I need to test the Trace C-40 charge
control and would appreciate suggestions on choosing a portable 0-16V variable
voltage power supply to check its function and set points etc. It should be as
easy as a couple batteries in series, multimeter and a potentiometer. Thanks
for your thoughts.<o:p></o:p></span></font><u1:p></u1:p></p>
