Battery to inverter cable question

[aliarogahn]

I am installing an EG4 6500ex, 8 455 watt Solarever panels and 2 Lifepower batteries, 48 volt - 5.12 kwh - 100ah.
I am only planning on running a small freezer and fridge . 100% off grid.
1 awg battery cables came with the system. Should I go larger than that between the batteries and inverter?
Is a 200 watt T class fuse be ok for the positive lead?

1 AWG cable can handle 119 amps. With a 48 volt battery bank that's 5,712 watts going to the inverter.
Modified sine wave inverters have an efficiency between 75%-85%, and high quality pure sine wave inverters have an efficiency between 90%-95%. Taking the worst case scenario, an inverter with an efficiency of 75%, you have a maximum of 4,284 watts output using the 1 AWG battery cables.
Since a full sized refrigerator only uses 700-1000 watts, you could run a full sized freezer and fridge, so you'll have no problem running a small refrigerator and freezer.

If you are going completely off grid, go with thermoelectric/propane units. The fridge/freezer in our camper runs on the 12v system when not using gas. The inverter represents unnecessary loss.
