# Sungrow SH Series Hybrid Inverter

Source: https://docs.evcc.io/en/meters/sungrow-sh-series-hybrid-inverter

Connections via the WiNet-S dongle (WiFi or LAN) only work with the latest firmware. Older versions do not provide all required data (power, state of charge).

Supported features: battery-control

## Known limitations

- For correct operation, maximum charge and discharge power must not be set too high.
