Sunsynk 3p hybrid inverter (battery)
Sunsynk
Overview
The Sunsynk 3p hybrid inverter is a three-phase solar hybrid inverter that manages power flow between PV, battery storage, the grid, and loads in commercial and residential installations. This ModbusCloud template connects via Modbus RTU over RS-485 and reads battery power, cumulative energy, and state of charge, while also exposing the full set of battery-mode program registers for remote charge and discharge scheduling. For installers and facility managers, it enables continuous battery monitoring and automated schedule control from a single cloud portal.
Use cases
- Monitor battery state of charge continuously to detect degradation or unexpected overnight discharge events.
- Track cumulative battery energy throughput over months to verify actual cycle use against design assumptions.
- Alert on battery power readings that exceed expected charge or discharge thresholds during off-peak periods.
- Compare live power register values against scheduled program setpoints to verify time-of-use control is active.
