Hello,
I am learning a bit about solar panel interconnection with the grid but i am just having trouble at one location.
Lets say you have two strings of panels connected to two inverters. From the inverters they go to a combiner which will have one output which gets connected to a meter and then a disconnect. Everything looks good until here.After this it feeds a panel which is main lugs only. Now my question is there are already wires terminated onto those lugs from utility side. Where would the cables from the disconnect terminate onto cause they are already used by the normal feed?
Second question is lets say you end up with a main backfeed breaker even then how is the termination done on the breaker with two sources of power supply? I was thinking of having an ATS at this point where one source lands to normal side and the other lands to solar side and the load side is connected to the panel.Am i missing something with this idea or is it just not right?
