Huawei SUN2000 Hybrid Inverter
Modbus TCP requires activation within the communication settings of the inverter using an "installer account", see Modbus TCP Activation Guide.
Grid and Battery require the Huawei Smart Power Sensor (DDSU/DTSU666 or SmartPS).
Multiple LUNA2000 towers connected to the same SUN2000 inverter are configured as a single logical battery.
Curtailment will limit the export power to the desired percentage of the maximum AC power. The inverter will automatically limit the PV power to achieve this.

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. | volitelné | |
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. | volitelné | |
capacity [kWh] | Battery capacity | volitelné | |
minsoc [%] | Minimum charge Lower limit as configured on the battery system. Used by optimizer. | volitelné | |
maxsoc [%] | Maximum charge Upper limit as configured on the battery system. Used by optimizer and, on some devices, for grid charging. | volitelné | |
maxacpower [W] | Maximum AC power of the hybrid inverter | pokročilé | |
forceaccharging | Inverter cascade Keep AC charging active (except for when being dimmed) to charge the storage from other inverters via AC. May prevent standby with older firmware versions. | pokročilé |
