You might want to look at the owner's manual on your inverter. 200ah of lithium is only enough to support a 2,000w inverter. 200ah x 12v = 2,400w. For the inverter you have you need a minimum of 300ah of capacity. 300ah x 12v = 3,600w. Otherwise, you can damage your two batteries pulling too much current from them.
