How to Wire an Enphase Micro-Inverter for an AC

Enphase Micro-Inverters are used to power solar panels on modern, energy-efficient homes. The proper wiring of these inverters is critical to ensure that the panels provide the home with the most energy in the safest way possible. The inverters convert solar energy collected from the adjacent panels into usable electricity for the homeowner.
