NameDescriptionValueLevel
idModbus ID
Default: 1
intrequired
deviceDevice name

USB-RS485 adapter

Example: /dev/ttyUSB0
required
baudrateBaudrate
Default: 9600
required
comsetComSet

Communication parameter for the adapter

Default: 8N1
required
hostIP address or hostname
Example: 192.0.2.2
required
portPort
Default: 502
intrequired
minsoc [%]Minimum charge

Lower limit as configured on the battery system. Used by optimizer.

Default: 10
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.

Default: 1200
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.

Default: 800
optional
capacity [kWh]Battery capacity
Default: 2.11
Example: 50
optional
maxacpower [W]Maximum AC power of the hybrid inverter
Default: 800
Example: 5000
