SMA Smart Energy Hybrid Inverter

← PV, Battery, Grid, Meter

When using active battery control by evcc, the 'Forecast-based Charging' function in the SMA portal must not be active. Otherwise, conflicts may arise when controlling the battery.

Supported features

Battery control: External control of home battery charging and discharging via evcc.

Usage areas

Grid meter
Solar production
Battery
