12-Volt to 110-Volt Conversion
Okay, I'm trying to figure out how much power my house batteries can supply iif I used a 12-to-110 Volt Inverter. I have two AGM Batteries that are rated at 210 Amp-Hours. From what I understand, you're not supposed to take them below a 50% charge. Does this mean I have 105 amps to use (I don't believe this is the case)? Is there a calculator or equation that can tell me how many watts are available at 110 Volts before the batteries get to 50% capacity? Let's say I have a 3000 watt Inverter and plan to load it at half it's rated capacity (1500 watts). How long would my batteries last (assuming the inverter uses a minor amount of power on its own)? I don't understand the relationship between the 12-volt side and the 110 volt side. Anyone have a better understanding of all this, that can explain it in layman's terms? :-)
