Fairly new to using solar. I have been reading up on volts vs. amps in terms of what makes the most efficient system. I am considering a 24v battery bank with 4 12v batteries connected together. These are the Kirkland 115a starting/marine batteries. I am also considering a Victron 100/50 MPPT charger. This is the math I have so far.
Mobil RA 220-8B solar panels 1991
rated at: 230w. 10.55volts. 30.48 amps.
kirkland batteries= 115 amp hours * 4 quantity * 24 volts = 11,040 watt hours to charge %100
6 ra-220 panels in parallel = 54v * 30a Isc = 1620w
11040w / 1620w = ~7 hours of full sun to charge from 0% to 100% *keeping in mind partial current from shade
is this math correct? Will this charger work well with this setup? Do you see a better way to set it up?
