Monitors and controls Huawei SUN2000 inverter with Luna2000 battery and DTSU666-H smart meter.
Overview
This ModbusCloud template monitors and controls a Huawei SUN2000 inverter paired with a Luna2000 battery and a DTSU666-H smart meter over Modbus TCP. It reads production power, energy yields, battery state of charge, grid import and export energy, inverter and battery temperatures, and system efficiency, and lets you write storage working mode, AC charging status, and max charge and discharge power setpoints.
Key readings
- Production power and total energy
- Daily energy yield
- Battery state of charge
- Grid import and export energy
- Inverter and battery temperatures
