I'm looking to install a small solar system on my garage. Current main panel is a 100A service, with what i believe to be an Eaton/Westinghouse/Cutler Hammer/whatever brand they are now 643532 BR 100A panel. Unfortunately, there is no label-plate/sticker in existence on the panel (circa 1994), so I have no definite way of knowing if it has a 100A bus, or 125A bus. Either way, the way I understand the NEC regarding multiple feeders, I should be able to run 120% of the bus in total feeders into the panel, so that would allow a 20A solar feeder, which would provide for up to 16A of 240V inverted power. With this in mind, I'm scheming on building a system using
16 - SolarWorld 275 Plus Black
16 - Enphase M250 MicroInverters
The M250's max out at 1.0A a piece, which brings my array to a max of 16A, feeding through a 20A breaker, into my main panel (I may opt to install a 50A subpanel closer to the array, to break out a couple breakers from the main, which is pretty congested, and leave some room for expansion for some landscaping lights and general outlet use).
Anyone see any problems with this setup, from a practicality, and/or code side?
