My experiance is limited, but I saw results of paralled AGMs cataching fire, It
was several years ago, I think is was only 4 parallel strings (maybe 6). It
happened during the day with a high charge rate. AGMs have a higher
temperature voltage temperature curve. The temperature got higher on

I'm looking for experiences/recommendations for a 15-20kW propane
generator. It would be going in an off-grid system with dual Outback
3600W inverter/chargers. The excess capacity would power larger loads
than the inverters can handle. Fuel economy and harsh environment
performance are the top prio
Can you say something more about the system? Is there a PV component? What
is the size and type of the battery bank?
The thing I am beginning to understand about propane generators is that
there is a problem with Outback charging re: partial load efficiency. If
the generator/chargers are sized
The propane and gasoline generators both ar premixed combustion and have a low
efficiency at part throttle/ part load. The Diesel does the best job of
maintaining efficency at low load. The outback can control its charging
current to the load limit of the generator. If the AC loads need more

Allen,
Can I infer that if you are shutting off the gen before charge rates drop in
absorption that you are running only briefly in the absorb phase? Or do your
charge currents remain high through out an extended absortion phase?
Perhaps you have plenty of PV which you rely upon to bring the ba
Mark,
Yeah, the gennie is set to come on automatically through the Mate,
but the homeowner pays attention.
There's about 5kW of array for this off-grid home as well, so it's a
gennie-backed PV system. Also, all modules are on trackers (long
boring story) so ther
As the % of full charge is related to the of degree
absorption & gravity [the denser & more charged acid
descending, and lighter acid rising] @ what point in the
absorption would be prudent to stop charging?
I used to cut off the charge on the Trace SW series at 12

Hello Wrenches,
After a busy 1.5 months, I'm finally getting back to setting up the software
for PowerSave Envi (aka Current Cost)monitoring system on our home/office PV
systems. What software do you recommend? As always, thank you for sharing what
you have learned.
Best regards,
Joel Davidson
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.
I'm really hoping that future software, theirs or 3rd party, can fix

That is a good question, I have not an answer, but of course it should be based
on the amp hour of the battery bank, absorb charging voltage, and of course the
charging source in the case of generators. Following Ron's advise start at C/5
for SOC less than 50% then C/10 till about 70% SOC and t

Wrenches,
I am looking for an Evergreen EC-120-GL to replace the one dinged by
the rock flung by my client "weeding" aroung the ground mounted array with a
lawn mower. It may take me a couple days to respond as I'm on the road.
Thanks in advance for any responses off-list.
