Re: What are the best batteries for the money?
From a energy view point, a 12 volt @ 110 AH battery is identical (in stored energy) to a 6 volt @ 220 AH battery: * Energy (Watt*Hours) = Volts * Amp*Hours = 12 volts * 110 AH = 1,320 Watt*Hours * E…2 · -
Re: LiFePO4 batteries...Rule of thumb changer?
100 AH per 1 kW of inverter capacity is @ 48 volts. At 24 volts that would be 500 Watts of inverter per 100 AH, and at 12 volts would be 250 Watts per 100 AH.... (this is also suggested as the nomina…1 · -
