Can anyone explain this?
We have 48/5000 Multiplus. We have been using it off grid with two homes which include two fridges etc. We run the usual items including computers, washing machine, dishwasher and other appliances.
A visitor in a RV with fridge plugged in to a 15 Amp outlet and was only able to achieve a fridge temperature of 6 degrees C. When unplugged from our power it rose to 11 degrees. He then relocated to an ongrid power supply and was able to achieve -2 degrees in the fridge.
Our fridges run at 4 degrees Fridge and - 18 degrees Freezer.
Any help explaining this is appreciated.
