Ricevs,
Makes sense, thanks. If the inverter is on all the time, but all the electronics plugged into it are off, then there is no current draw from the inverter. So the batteries won't get drained. But if the low power electronics like preamp and sources are on all the time, then the batteries will drain at a slow but significant rate. If you want to keep the low level electronics on all the time, then it seems that the most economical procedure is to keep the inverter off when not listening, then turn it on first, and then the power amp. Does the battery charger get warm/hot when running the majority of the time?
Correct?
