We are completing the wiring on all our backyard solar arrays. Together, they total 12.6kw of solar PV. We are wiring these in large series strings to make high voltage DC. This will feed into our garage through an underground conduit. The solar MPPT charge controllers are built into the Growatt inverters, model SPF 5000 ES. Each 5kw inverter can accept up to 6000 watts of solar PV input, and up to 450 volts DC. Using high voltage PV helps lower the cost of wires and combiner boxes.
