Buy you a 24 volt 40 to 60 amp Battery Charger and a 24 volt 1000 to 2000 watt Inverter and forget all about solar. But if you insist on throwing away money on solar, just based on the 4 batteries you have now will require a 1000 watt Solar Panel ($1500 to $2000) plus a 40-Amp MPPT Charge Controller ($400).
Solar panels output more than their nominal voltage. For example, a 12v solar panel might put out up to 19 volts. While a 12v battery can take up to 14 or 15 volts when charging, 19 volts is simply too much and could lead to damage from overcharging. Solar charge controllers aren''t an optional component that delivers increased efficiency.
