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

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 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.		optional
`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.		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
