I have 3 Lipo4 12V 100Ah batteries that I am going to setup in Parallel which would be roughly 3600watts, What size inverter should I use? I currently have a 2200/4400 watt inverter should I get a bigger one? I have 6 ea 100watt solar panels that I will utilize.
Correct Inverter size?

Size the inverter for the loads you plan to apply. If you need to pull more than 2200 watts continuous then you'll need a larger inverter and you may need to add more to your battery bank.
Do the math, otherwise you'll be spending money to replace parts that weren't sized right.

They are Ampere Time 12V 100Ah Lifepo4 batteries

3 in parallel can deliver ~300 amps.
Lets de-retate to 80% to cover any mismatch in path resistance.
Thats a realistic 240 amps.
Your inverter can draw
2200 ac watts / .85 inverter efficiency / 10 volts low cutoff = 258.823529412 service amps.
Your batteries can just about cover the inverter that you have.
Thank you I was never good at math
