Do you realize what 2000 watts does to your battery? If you were to run close to 2000 Watts you'd be drawing almost 170 amps. If you only run 1000 Watts you'd still be close to 80 amps. It either case the battery would only last a couple hours and wiring between the inverter and the batter would have to be able to carry that full 170 Amps.

I think folks with a 2k inverter only run it for a couple minutes at high loads. What's a coffee take to nuke, 2 min? How about dry your hair, 5 min? Still a lot of amps but not as bad as it sounds.

I installed a 1k inverter, biggest hassle is finding a spot big enough for it close enough to the batteries to make the cable size required manageable. Need to find big enough fuses and a holder that will accept the wire gauge and mount them somewhere too. Did you look at the dimensions of the inverter?

Basic plan is to maintain a 1.3 amp 120v ac frig. 24/7, anything above that will be nice to have. Will be using 3 trojan #31 batteies with 531 amps rc. Renogy 2000w of pure sine wave for $420 usd with 4 #4 x 24" cables is well priced. Unit is 18"x8x3", total package will fit in 24"x24" space below side seat of 1989 16' cassie.

It appears the 531 amps RC you mention for the AGM-31 are listed as only 300 using the normally referenced 20 hour rate. I don't know how much power the inverter uses just by itself, but the 156 watt fridge will be drawing as much as 13 amps at 12 volts when running. Do you have enough solar power to recharge the batteries at that rate, or are you just looking for something to cover you for a couple of days between hookups? (I am not an electric expert so my numbers may be way off)

Basic rule-- Anything that runs on 120 VAC with require 10x that to run on 12 DC. your 1.3 amp 120VAC fridge will require in excess 13 Amps from the battery. Most inverters are only about 95% efficient near max rating. Gets worse at lower areas.

The Renogy spec says 85% efficient.
