1 40071 L 68 uint16 1 R Y Model Length Model length
2 40072 VAMax uint16 1 P_SF VA R Y Maximum apparent power Maximum apparent power
3 40073 WChaMax int16 1 P_SF W R Y Max Charging Power Maximum instantaneous active charging power considering battery, inverter and site limits. A negative value means the battery should discharge with at minimum this value to respect e.g. the site limits.
4 40074 WDisChaMax int16 1 P_SF W R Y Max Discharging Power Maximum instantaneous active discharging power considering battery, inverter and site limits. A negative value means the battery should charge with at minimum this value to respect e.g. the site limits.
5 40075 WMeas int16 1 P_SF W R Y AC active power AC active power measured by the inverter
6 40076 VAMeas int16 1 P_SF VA R Y AC apparent power AC apparent power measured by the inverter
7 40077 VARMeas int16 1 P_SF VAR R Y AC reactive power AC reactive power measured by the inverter
8 40078 PFMeas int16 1 PF_SF Pct R Y AC power factor AC power factor measured by the inverter. IEEE convention: positive is leading (capacitive), negative is lagging (inductive).

Default control 1 Default battery power control.
External power setpoint control 90 System will listen to external power setpoints Wset and VARSet.
External reactive setpoint control 91 System will listen to external reactive power setpoints VARSet, but use its internal controller for the active power setpoint. The reactive power setpoint will have priority and if needed limit the active power.
24 40094 WSet int16 1 P_SF W RW Y Active power setpoint Active power setpoint. Positive is charging, negative is discharging.
25 40095 VARSet int16 1 P_SF VAR RW Y Reactive power setpoint Reactive power setpoint. Positive is capacitive. Negative is inductive.
