Hi there I have these 16 12V CONCORDE AGM Batteries, and not much else including not a lot of money - though I have to go OFFGrid in about a month. Any Help, or references would help me tremendously
I have No Solar Panels or Large Inverter yet, I do have a 1500Watt 12 V Samlex Pure Sine Wave Inverter, and also do have a 120 V 33amp Cummins Onan 4000 watt 120v (only) Microquiet RV Generator and a 4200 Watt, ( 5200 Surge ) 120/240 V Portable Generac Generator to Recharge
them with three 120 V 12 Car Battery chargers with AGM as one Setting.
I am trying to figure out the Best way to:
0) How to best physically Interconnect them all -and allow for their maintenance: Just huge honking wires directly connected to each other, Junction Boxes, Massive Current Switches ( the 1500 Watt Inverter alone on 12v could draw over 125Amps ! ) , Home built electronics, Store bought electronics ???
1) How to best electrically Interconnect them: All 16 X 12 V batteries in Parallel, All in Series = 16 X 12v = 192V, 4 Parallel banks of 4 X 12 V =48V in parallel, Separate Banks of 4 X 12 -48V with no Parallel banking ??
same for 24V .... Others
2) As I vary Interconnects in 1) , How to best Invert the Final Dc Battery Voltage to 120 VAC, or even 240 VAC, how to also best Charge the Batteries Obviously the 12 V charger rapidly falls away as we move beyond 12V systems replaced by ??
3) Any other Ideas ??
