First, does the refrigerator
even need and inverter
to run or is it an AC/DC refrigerator
that runs on shore power
if available and 12 volts DC if not? Personally, I think this is a better solution for most of us rather than some sort of "home" or "dorm" refrigerator for better efficiency.
Get out the
But really, your entire question cannot be answered without a lot more information. Information such as the current
draw of the appliances
including any startup or surge current
, the maximum and continuous power
capability of the inverter and the capacity of the batteries
in Amp Hours.
You certainly need to run the genset (or plug
into shorepower) to operate an air conditioner, range and/or oven
. You may or may not be able to run a microwave over on inverter/battery power. It can be done on my boat
but I planned and sized my equipment
for this operation.
