Batteries

So I just received my new solar panels. I bought 2 Bi-facial 220 watt panels, that should provide about 500 watts of power, in direct sunlight. I also am replacing my 10 amp PWM controller, with a 40 amp Mppt controller. That and the 2 new lifepo4 batteries will be awesome. I should be pretty much energy self sufficient, barring several cloudy days in a row. Even at that, if I shut off the DC fridge, i'd be fine. Can't wait till spring to get it all installed. I'll have 180 watts of solar for sale at that point. I am removing my pre exsisting panels so my system can work as efficiently as possible. I have to start researching an inverter now. I know nothing about it. I'm hoping to run the t.v. , maybe a nice fan, and a keurig coffee pot. I figure at least a thousand watt would be needed? Don't really know. If anyone has good inverter knowledge, I'd like to hear. 

Congratulations! I'm looking forward to reading about the results when you get a chance to use them.

I have a now 3 year old Trojan T-1275 battery that puts out 165AH, pretty good for a 12v LA battery but also a heavy weight at 85 lbs.  Between that and our 12+ year old Interstate we go 7 days off grid when night temps are in the 40's with the furnace running a lot.  But you present a new challenge with running a fridge that is NOT propane.  Hopefully, by the time ours quits functioning there will be some good alternatives to the current Dometic 8501.
