Small cabin solar/battery and Inverter setup

[FredMac]

Good afternoon, I really enjoyed your videos. I wish I had seen them sooner.

Here is my current setup and would like your feedback on this 12V system.

I have a 400sqft cabin and I have wired it with 12/2 wire from the breaker panel out.

The breaker panel has a main 30amp breaker that feeds two 20amp circuits within the cabin one for the right side and one for the left side to power receptacles with or without USB ports, lights, and switches.

The 30-amp main breaker is connected to a Renogy 3000-watt inverter with ATS/Charging capabilities that allows me to go DC or AC.

The inverter is connected to two 12V 100 AMP HR Lithium Battleborn batteries in parallel for DC power and the AC input to the inverter is connected to a 30-amp generator for AC power.

I have two Solarworld Sun modules SW 230 Poly solar panels connected to a Renogy 40amp MPPT controller and my batteries.

Do you see any concerns with how I am approaching this?

Thank you,

Sounds pretty good for a basic system, I don't really see any issues with the plan. About the only thing I could think of would be to add some sort of shunt to keep an eye on your batteries capacity so you know when to fire up the generator BEFORE the lights go out.
