Start request - Word
provided no error is
currently present
Stop request - Word
prevent if from restarting as soon
as the error has disappeared
Reset fault - Word

Set P kW Float Active power (kW) to be
injected into the grid (when in
current source mode). Positive
target means discharging
Set Q kvar Float Reactive power (kvar) to be
injected into the grid
(when positive, inverter
behaves like a capacitor)
Heart beat
timeout
- Word Heart beat signal: Once modbus
client has set it to non-zero value,
at least otherwise the inverter
will stop and generate a
