So after running into a roadblock with my 18kpv and backup plans with my utility (they require a separate production meter) Ive decided to go net metering only for now. Im gonna try to find two sunny boy 7.0 inverters (unfortunately just discontinued). They said I could keep my old plan and add a couple of inverters before the 18kpv and do ac coupled but thats just not in my budget so Im deleting the 18kpv and battery.
Please check my diagram. I think Ive got the DC side sorted here. What I need help with is combining AC after the inverters. Whats the best way to AC combine? A couple of 40a breakers going in and a 100a going out to the production meter? A bus bar coming in and a breaker going out?
also, please check my disconnect to line tap. What OCP do I need between the disconnect and tap, or should I just do a fused disconnect?
I know my meter/main breaker and main house panel is funky with the two neutral bonds. I can always run a ground from the outside meter and delete the neutral bond inside if the utility doesn't like it. No city/county inspections here. This is how they installed it 20 years ago.
I decided to go line tap because my panel bus bar is (I think)225a and ive got a 200a breaker in it. #30ax2x1.25 is 75a. I could only do max 70a backfeed breaker.
also, anyone with sunny boy experience, If i went with the 7.7kw model, could I limit them to be under 15kw together? My net metering agreement is for 15kw and under.
Thanks so much. This forum is wonderful.
will be limited to 15kw and below.
