Solplanet Hybrid inverter (Modbus TCP)

← PV, Battery, Grid, Meter

Only for inverters with a dedicated Modbus TCP ethernet port (e.g. ASW-TH series, KACO Blueplanet Hybrid NH3, port eth 5&6), protocol AISWEI "MB001_ASW GEN-Modbus" V2.1.7. Older devices without that port need the solplanet-ai-dongle template instead. The grid meter import/export energy counters (46443/46445) are not exposed over Modbus TCP by this firmware. With two battery packs (BMS1 + BMS2) add one battery meter each, using battery number 1 and 2.

Supported features

Battery control: External control of home battery charging and discharging via evcc.
Curtailable: Inverter production can be reduced (e.g. § 9 EEG). See External Limit.
