SofarSolar
Overview
The SofarSolar SOFAR 5…24KTL-G3 is a three-phase on-grid PV inverter covering 5 to 24 kW, used in residential and small commercial solar installations. This ModbusCloud template connects via Modbus RTU over RS485 and reads the inverter's grid interface: total active power, per-phase currents and active power for phases A, B, and C, and the cumulative energy export counter. With per-phase visibility and a running energy total, installers and building owners can verify grid balance, detect phase asymmetry, and track long-term generation performance directly from the ModbusCloud portal.
Use cases
- Monitor total active grid power in real time to verify the inverter is delivering its rated output.
- Track per-phase active power on phases A, B, and C to detect load imbalances across the three-phase supply.
- Alert on unexpected sign changes in the power register to catch unplanned import events during daylight hours.
- Compare cumulative energy export readings over weeks and months to identify capacity degradation trends.
