Hello everyone :-)
I have a 7.3kW Genny (AC) and two chargers (60A and 45A).
One is working on service
bank (6x120Ah AGM) , other on 2x200Ah engine
bank (serving also winches, bow-thrust and windlass).
I want to make best use of AGM
high recharge rate, using the TWO CHARGERS all at once on AGMs
I understand that an AGM charger
can be 20/25% of nominal Ampp, so 60+45Amp does look just on the low side, and 60A really underscoring...
Thus, shall I:
- apply both chargers on same terminals as one bank
- divide the banks (3+3, or 3+2) and keep the 2 chargers independent. ??
Well, I know that prudence and common sense do suggest 'BETTER NOT .. well, really??, and WHY??
batteries are seen by chargers as a utility absorbing current
I hardly figure out current
entering the other charger
... (if OFF, maybe...)
The two-bank solution implies double Battery Monitor
, and a rotating switch to put them together when in use (not under charge)... so I'd rather go on a single
bank fed by 2 chargers...
is just 25A, thus, as smaller (fractional ) bank could be better, in that regard (that A equal to 3% of the bank capacity being just good for floating the big bank)....
Comments welcome :-) (I don't want to burn, neither in hell nor afloat....)
