I'll post a page outlining my solar electrical installation, now ready for state inspection.

Earth ground bonds include solar negative, disconnect switch enclosure chassis, main panel chassis, solar controller chassis with both negative potentials, battery negative, inverter chassis, as well as the inverter AC neutral output (bonded to Earth potential by the standard green bonding screw.)

Inspectors here rarely encounter an off-grid solar inspection, needed for insurance purposes.

A few pictures disclosing the bonding techniques may be informative.

The only thing I may need to do is enclose the 24-volt solar power conductors in conduit. There is conduit for these lines from the controller to the basement, as well as for the inverter AC lines. The Morningstar 60A controller is mounted next to the main panel immediately behind my entry door. It is a nice-looking, neat installation. Solar connections use pre-made MC4 to the exterior disconnect switch. It is temporarily a 650-watt, 2-panel array with for 180 ah, 12-volt batteries configured for 24-volts. It performs well, charging batteries even on cloudy days. The AIMS 5000-watt inverter pumps water from my 4-inch deep well with no problem. It also runs my compressor on the 15-amp, ground fault circuit which includes outlets in my small kitchen and bathroom as well as the outdoor, weatherized outlet.
