Oops
Just remembered that you don't have grid.
Just remembered that you don't have grid.
Let's say a battery is sitting at 12.0v. If a charger set's itself to 12.0v, then no current will flow and the the battery cannot be charged 'higher' than 12.0v. To get current to flow, a charger has to raise the voltage higher at the battery.. say 12.5v... and then the current will flow into the 12.0v battery. Once the battery get's to 12.5v, then current will stop flowing and no further charge will happen.Can you please elaborate more on this point? I didn't get what do you mean by it.
How are these wired? Are they wired in a balanced manner or ?? Any pics?220AH/12v set in 3 parallel banks of 4 batteries each.
Problem is that there is no always grid power where I liveJust set the "back to utility " at 48v.
basically go darkIs it setup to start a generator?
Or just go dark?
an electric technician took care of the wiring. I just called him, he said that they are wired as 2 banks of 6 batteries each with 2 batteries set as stand by in each bank (I'm not sure how this is possible), and the batteries are connected to an optimizer.How are these wired?

Yes I believe this is the best approach, I will do it once I reach home. thanks for your help.Maybe switch to user defined battery settings.
And change low cutoff to 48v.
Not badYes I believe this is the best approach, I will do it once I reach home. thanks for your help.
Now after 8 hours of battery mode, battery voltage is at 49v (load is stable at 800w), is this considered good so far?
Now i am REALLY curious... would love to see a pic.an electric technician took care of the wiring.

pic will not really help as most wires will not be clear, but from what I described, is this an efficient setup?Now i am REALLY curious... would love to see a pic.

As described it sounds wrong to me. To get 48V from 12V batteries, 4 need to be in series. If you have 8 batteries, then the 2 sets of 4 in series are paralleled (preferably balanced with the wiring to/from the + of one bank and the - of the other bank).from what I described, is this an efficient setup?

Not sure how to do that with 6 batteries and have no idea what 2 as stand by could mean.
I'm still game for a pic or 2.
