Too much solar?

Hello all. I have lived off grid for a little while and am upgrading my system. I just want to make sure my set up is right and my panels are okay. I plan on using the AIO MPP PIP1012LV-MK. It's 12 volt. I also am getting (2) 12 volt 200AH lifepo4 batteries. My current panels are (2) 280 watts. Spec below
Pmax. 280
Vmp 31.7
Imp 8.8
Voc 38.4
Isc 9.42

I am also getting (2) 320 watt panels
Pmax 320
Vmp 34.1
Imp 9.37
Voc 40.5
Isc 10.2
The all in one is max 1000 watts solar and if wired series parallel it will be about 1150 watts I believe nit %100 because of mismatched panels. Will this still work for AIO? Is my math off? Thank you all
 
2S 280W in parallel with 2S 320W will work fine.

Due to the mismatch in Vmp, they both will suffer a little, but I wouldn't expect more than a 5-10% hit - still well worth adding the mismatched panels.
 
Energy guide says 339kWh/year. That's 0.93kWh/day

~1000W+ of solar is more than enough for that in typical solar conditions. The 1000W inverter should handle any surge, but I would confirm that if possible. You might have to lay hands on one and look at the ratings on the compressor.
 
There are some 120V fridges in that size class which do not have the frost free function… less power needed and white not stainless- but half the price.

Can you link me to some. With the AIO work with a frige that has the surge vs inverter compressor?
 
I haven’t looked in a while but there is one on the same page with your link that’s a bit smaller but NOT frost free (advantage on solar)

This one is 10cf but is frost free and half the cost. But the frostfree costs a lot of wattage
