I have a project where I am combing 6 inverters for a grid-tie system:
(4) SMA SB8000TL's
(2) SMA SB6000TL-22's
The Grid is 208Y 3-phase, 225A
I am planning on using an Eaton load center (3-phase), using 2-pole breakers for the inverters. 50A breakers for the 8's and 40A for the 6's. Output for the 8's is 38.5A and 25A for the 6's, which gives me a total of 204A, upped to 255A (125%). The panel I am looking at is a 225A rated CH series, which would allow me 270A (120%).
Does this seem feasible?
Oh, regarding existing loads on the utility, there is only an old 225A panel that has a pump attached (was all to be removed / demolished before the client decided they wanted to have solar). So we are going to simply tap at the meter (or splice box) and leave the existing alone.
