Grid-Tied Solar Microinverter 600W with MPPT

Small, grid-tied DIY solar.

This 600 W grid-tied microinverter converts DC power from one or two solar panels directly into AC power synchronized with the utility grid. It is commonly used by experienced DIYers, engineers, educators, and solar hobbyists for testing, demonstrations, and limited plug-in solar projects.

Not suitable for off grid or backup system unless you already have a battery inverter. This device requires an active utility grid and will automatically shut down during a power outage.
