Now that I’m here, I’m looking for some tips on an off grid solar+battery system for my cabin in the Sierra foothills. Power cut offs are frequent enough to just give up and go off grid. I have a number of the components identified, but I have some questions to resolve. Initially involving realistic battery power availability.
Number one, help me with the arithmetic, if I have four 12 volt, 100 Ah batteries, in series for 48volts, do I have: 12x100, 1200Ah x 4 = 4.8 kwhr, or 48x400 = 9.2kwhr?
Next, since the power band for a 48 volt system has an effective range down to 40-42 volts, what kwhr can I expect to draw when operating on only batteries?
Cheers!
