I now have two 5.32kw batteries in parallel. I had hoped this would result in my inverter now suppling a peak power of 3.6kw, but I'm still only seeing approx. 2.6kw. Is there something I need to change in the settings?

I've set the battery size to 200 from 100, and max charge/discharge to 90A. (Won't accept 100a as suggested).
