# SMA Smart Energy Hybrid Inverter

Source: https://docs.evcc.io/en/meters/sma-smart-energy-hybrid-inverter

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

## Parameters
