SAJ H1 Series Hybrid Solar Inverter (pv)
SAJ
Overview
The SAJ H1 Series is a single-phase hybrid solar inverter for residential energy storage, covering 3 to 6 kW with dual MPPT inputs and a 48 V battery port. This Modbus TCP template reads two core PV registers: instantaneous generation power and cumulative energy yield. Connecting the SAJ H1 Series to ModbusCloud via the ModbusCloud Gateway gives installers and building owners a continuous, cloud-accessible record of solar production, enabling performance tracking and yield verification without manual data collection.
Use cases
- Monitor real-time PV generation power to verify the inverter is producing at expected levels during daylight hours.
- Track cumulative energy yield over weeks and months to detect gradual output degradation or soiling losses.
- Compare daily energy totals against forecast irradiation data to flag underperforming strings or shading events.
- Alert on sustained zero-power readings during daylight to catch tripped protection or communication faults quickly.
