Yes, I've had a 48 v system survive a dead cell (Outback inverter),
but 24
or 12 v systems are done. So I guess the Sunnyboy can go down to 42 V?

I believe the Sunny Island 5048 can be configured to remain "online" with up to
three cell failures. (Page 90, Sunny Island Manual). Of course, it is a 48 volt
inverter.

I used to think that one string was optimal; until I had a single cell failure
take out an entire system for weeks. (try operating a 24 v system at 22v! )
I now think that 2 parallel strings is optimum, 3 is OK, and 4 is max.
At 4 parallel strings, we start spending more time looking to make sur
ng buss bars as parallel connections and
the inverter connection point and leaving the series strings physically
isolated from one another.

Conrad,
We have sold many Concord (Lifeline, Sun Xtender...) batteries over the
years. They are the best and half of our battery sale
Reposting from mid-October, in response, Todd:
We have one off-grid customer who is well into his seventies. He has an
old/upgraded 12V system, originally installed by Windy in the late 1980s. (He’s
the only customer we care for who is still using his original basic Trace 1512

Hello Todd,
Since your strong opinion is a completely negative one, I suggest you
study the installations you have had trouble with. I have seen many
poorly designed systems that cause to the demise of the battery. Far
too many parallel strings and undersized charge systems are the worst

Conrad,
We have sold many Concord (Lifeline, Sun Xtender...) batteries over
the years. They are the best and half of our battery sales are Deka
and Concord AGM's.
When our mobile customers abuse their AGM batteries, I use an
equalization process that has a constant current and no voltage
As someone who has been doing off grid systems since 1985 I can say from
experience, ALL sealed batteries are CRAP... especially in off grid
applications. They are too fragile and do not last.

Hi Conrad,
1. Not usually a good idea to EQ sealed small batteries. This will hasten
their death.
2. Best bet at this point is charge them individually or at least parallel at
12v
3. If possible put them on a long long charge to see if they actually charge up.
4. what are the charge set poin
