SAJ Inverter R5_V1
SAJ
Monitors a single-phase SAJ solar inverter via Modbus RTU
Overview
This template connects to a SAJ R5 single-phase solar inverter via Modbus RTU at 2400 baud. It reads PV string voltages, currents and power for up to three strings, AC output parameters, energy totals, inverter temperature, fault messages and insulation resistance values.
Key readings
- PV1 to PV3 voltage, current, power
- AC L1 to L3 voltage, current, power
- Total and daily energy
- Inverter temperature
- Fault message and error count
- Insulation resistance ISO1 to ISO4
