Am I thinking correctly?
I have a 18kpv, critical load panel and 1 indoor wall battery. I recently installed solar panels and was playing with the settings. At one point, I was backfeeding and I panicked a little bit. I have no agreement to do so and I don't want to raise any red flags. But I think I was ok and might implement backfeed up to 500w.
My CTs are on the feeder line (from feeder breaker) going into the inverter. The system sees me over producing solar and back-feed the grid, but really since my mains still are pulling 1kw constant, I am really not back-feeding the grid but really just powering the loads on the mains. Is this theory correct?
Is there a way to maybe implement 2 CT sensors and use the house as a solar dump? Example, have CT on the main wires and then CT on the grid tie line and use the difference? If you have an extra 2kw of solar (after battery is full and critical loads are powered) have the MAIN CT read that you are pulling 1.2kw of power on the main panel and allow the inverter "back-feed" house/feeder breaker that extra solar but don't go over. I'm sure you want a buffer incase a big load turns off, you have room to absorb the difference for a second.
