Solax Hybrid X1/X3 G3/G4 (pv)
Solax
Overview
The Solax Hybrid X1/X3 G3/G4 is a hybrid solar inverter series covering single-phase (X1) and three-phase (X3) residential and light-commercial installations. This ModbusCloud template connects via Modbus RTU over RS-485 and reads the two PV string power outputs (power_a and power_b) plus the cumulative total energy register. With these three values in your portal, you can track live solar generation per MPPT string and log long-term yield, giving installers and asset managers a clear picture of array performance without additional metering hardware.
Use cases
- Monitor real-time DC output from each PV string separately to detect shading or soiling on one array.
- Compare power_a and power_b over a day to verify that both MPPT channels are performing equally.
- Track cumulative energy yield to validate against forecast models and report to building owners monthly.
- Alert on sustained low combined PV output during daylight hours to flag potential inverter or string faults.
