Solplanet AI-Dongle LAN (local HTTP API)

← PV, Battery, Grid, Meter

Uses the AI-Dongle local HTTP API (e.g. BA121T-30) instead of Modbus TCP. The inverter serial number (isn) can be read via http://<host>:8484/getdev.cgi?device=2. Battery control charge power is fixed at 5000 W.

Supported features

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

Usage areas

Grid meter
Solar production

Parameters

Name	Description	Level
`host`	IP address or hostname Example: `192.0.2.2`	optional
`serial`	Inverter serial number (isn)	optional
`capacity` [kWh]	Battery capacity Example: `50`	optional
`minsoc` [%]	Minimum charge Lower limit as configured on the battery system. Used by optimizer. Default: `0` Example: `25`	optional
`maxsoc` [%]	Maximum charge Upper limit as configured on the battery system. Used by optimizer and, on some devices, for grid charging. Default: `100` Example: `95`	optional
`maxchargepower` [W]	Maximum charge power Highest power the battery system can charge with. The optimizer plans with charging up to this power. Some devices also use it as grid charging power.	advanced
`maxdischargepower` [W]	Maximum discharge power Highest power the battery system can discharge with. The optimizer plans with discharging up to this power. Smart mode assumes the battery supplies at most this power to vehicle charging.	advanced
