Is this an accurate assumption disregarding all derations
10 amp load at 120 volts is 1200 watts. Powered by a 12 volt battery supplying an inverter. The battery must supply the same 1200 watts of power so at 12 volts the load is 100 amps. This would mean that the wires connecting the battery to the inverter must have an ampacity of at leas 100 amps. Is this accurate. I have an engineer type telling me no this is not accurate, but the math seems simple to me. What am I missing. Thanks
