It seems to me that the inverter need not run all the time, especially if stored or parked for long periods. I must keep a close eye on the battery fluid level because of this. I have often thought of putting a manual switch on the inverter and turning it off for a few days at a time when parked and not in use. I know all the lights run off the battery but when stored little battery used items are in use. I have manually unplugged the inverter for a week at a time with no ill effect so why not a switch? Comments?
