Sunsynk Micro inverter (pv)
Sunsynk
Overview
The Sunsynk Micro inverter is a single-phase, grid-tied PV inverter designed for straightforward residential solar installations, supporting up to four solar panels per unit. This ModbusCloud template communicates via Modbus RTU over an RS485 serial connection and reads two core registers from the Micro inverter: instantaneous output power and cumulative energy generation. With these values flowing into your ModbusCloud portal, you can track real-time PV yield and total production history across one or more units from a single interface.
Use cases
- Monitor instantaneous output power to verify the Micro inverter is producing during daylight hours.
- Track cumulative energy generation daily to confirm expected PV yield against forecast irradiance data.
- Alert on zero power readings during daytime to detect a tripped or disconnected Micro inverter promptly.
- Compare energy totals across multiple Micro inverter units on the same site to spot underperforming strings.
