My residential fridge spikes over 900w surge, when starting the compressor, that's about 80 amps, that's why it takes a large inverter to power the fridge , start up surge, with out batteries where will the inverter get the amps for the startup ?
How big is your converter, will it do that ?
I suggest you leave the batteries connected
I have a residential refer with four 6V batteries. Thanks for any advice!
if the fridge is on, leave the battery switch on
if the fridge is OFF you should be able to safely disconnect for several weeks, but again it depends on the converter
but WHY be plugged in, if storing the coach and NOT charging the batteries ?
more batteries die from neglect than over charging
