Hi Teronuc,
How long was the extension cord between the inverter and fridge,
and what gauge?
With an electrical supply at its limits, you want short, heavy-gauge extensions to get
maximum voltage to the fridge.
Here's one of many voltage drop calculators:
https://www.calculator.net/voltage-drop ... &x=49&y=18For a 120V, 13A load and a distance of 100', voltage at the end of a 14ga cord would be about 113V,
and for a 10 ga cord it would be 117V.
Our Dewalt DXAEP1000 1000w inverter is rated for a 2000w surge.
It will start and run a fifteen year old fridge, and I can then plug in our chest freezer as well.
Very handy when the outer bands of hurricane winds knock out power in our rural area.
Power vehicle is a 1982 Toyota Diesel pickup with two 12V AGM batteries.
Our fifteen year old fridge pulls a steady 550w running, and
was around 1150w at startup, according to the meter on the inverter.
(Many meters don't read short-term surges well.)

That could be enough to run our well pump.
Thanks and good health, Weogo
