A licensed electrician who probably didn't know that much about solar (not that I do!) told me I needed a line side tap. My residential service is single phase, 125A busbar with 100A overcurrent protection. The mains are underground and the transformer is not that clo$e. :>( I would prefer not to derate.
I am installing an Outback Radian 4048A rated at 4000W, with 16.7 Aac output @ 240 volts.
Seems to me I have 50 Amps of excess overcurrent protection available and the highest amperage backfeed would be 16.7 X 2 X 125% = 41.7 amps. So they could put a 50 amp breaker in the main panel for the critical loads subpanel and I am on my way.
My service panel cannot be easily tapped because it has a mechanical link from the meter to the busbar, and not a wired one....
I asked another solar electrician who is "looking into it." Maybe I am oversimplifying this?
I would be very grateful for an insight you can give me.
