Efficiency Losses So far in my posts, I've not really talked much about efficiency loss - it's ever present but quite hard to accurately measure. When the inverter charges the battery, resistance within the circuitry means that some of the energy is lost as heat. In my graphing, we can see that the inverter temperature starts rising in the middle of the night, dropping...
