PROS AND CONS OF MICRO INVERTERS VS STRING

Micro grid-connected inverter anti-reverse flow

For household low-power grid-connected inverters, the output current is small, generally less than 80A current models (within 50KW), you can directly use a DC anti-reverse current meter, the inverter AC output terminal wiring is directly introduced into the meter, and then connected to the grid point after coming out of the meter to achieve anti-reverse current.
