The 1000w inverter will run the fridge, but needs more battery plus about 300w of solar to stay running a few days. Four batteries instead of one might do it, depending on how long.
The 1000w inverter will not run even a small "700w" microwave, which would need 1100w. A 1500w inverter would with the four batteries.
The issue is how to keep those batteries from running down while running the fridge. 300w of solar would do it if the sun shines every day he is out there. Or use the generator every day for a few hours. That generator will run a 35 amp charger, which isn't much for four batteries, so it will take a long time each day. Needs lots of fuel for the generator.
Expect some sunny days and some not with using the generator a lot.
He will need to be able to tell how the batteries are doing, so he can tell whether the generator has to be used. This is vital!!
All because of that fridge! It will go through batteries in no time even though it is small. BTDT.
So use the little fridge as an ice box, or else spend lots of money to get the TT set up for off-grid, or get one of those small fridges that can work off a propane bottle (not cheap either).
