Ferroamp EnergyHub

← PV, Battery, Grid, Meter

Modbus TCP has to be enabled for the EnergyHub by the installer or Ferroamp support. The interface is only reachable via the EnergyHub's Ethernet interface. Grid values are measured by the external current transformers (CTs) at the grid connection point.

Supported features

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

Usage areas

Grid meter
Solar production
Battery

Parameters

Name	Description	Value	Level
`id`	Modbus ID Default: `1`	int	required
`host`	IP address or hostname Example: `192.0.2.2`		required
`port`	Port Default: `502`	int	required
`maxchargepower` [W]	Maximum charge power For forced charging of the battery.		optional
`maxdischargepower` [W]	Maximum discharge power Maximum discharge power of the storage.		optional
`minsoc` [%]	Minimum charge Lower limit when discharging the battery in normal operation Example: `25`		optional
`maxsoc` [%]	Maximum charge Upper limit when charging the battery from the grid Example: `95`		optional
