SAJ H1 Series Hybrid Solar Inverter (grid)
SAJ
Overview
The SAJ H1 Series is a single-phase hybrid solar inverter designed for residential and small-commercial energy storage systems, combining PV generation, battery management, and grid interaction in one unit. This Modbus TCP template reads two key grid-side registers from the SAJ H1 Series: instantaneous active grid power and a cumulative energy counter. Connecting via the ModbusCloud Gateway, these readings give installers and building owners a live and historical view of grid exchange, supporting energy reporting and anomaly detection without requiring cloud access through SAJ's own portal.
Use cases
- Monitor instantaneous grid power to verify whether the SAJ H1 Series inverter is importing or exporting at any given moment.
- Track cumulative energy totals over time to generate monthly or annual grid-exchange reports for building owners.
- Alert on sustained grid import during daylight hours to detect possible PV underperformance or inverter faults.
