Why switch to a Residential Refrig, thinking out loud !!

Mosheh,
A 1000 watt inverter is fine if that is your only ac toy. Run anything else and you will come up short. If you turn your frig off and on like a light to enable running other acc toys you will shorten its life. A residential frig needs a steady, 24 hour supply of ac power and since your warranty is probably void it is something to consider.If you are an AC- aholic maybe non hookups isn't the best way to go.
