200 Amp Whole House Transfer Switch
I am looking for advice on automatic 200 Amp transfer switches for Solar/battery main using grid power as the backup. I am in Hawaii with highest utility costs in USA where typical electric bills are $700-$1000 without AC. I want to use my solar system of 13Kw array, multiple-linked 5Kw inverter/chargers and battery farm of 9 parallel 200Ah 48v lifepo4 as the main power with grid(not generator) backup power. Which transfer switch would work in this setup? Originally, I used a simple, manual interlock switch on 200A breakers in my service entrance load center(fed from the solar system power subpanel) but now all non-grid-feedback systems must have a transfer switch. I have spent days reading through the manufacturers docs on ATS but can't find anything on using solar inverter/battery systems as primary or backup. Any help?
