Deye Micro inverter (pv)
Deye
Overview
The Deye Micro inverter is a grid-tie PV micro inverter designed for rooftop and small-scale solar installations, converting DC power from individual panels into AC for the grid. This ModbusCloud template communicates via Modbus RTU over RS485 and reads two core registers: instantaneous AC output power and cumulative energy yield. With these values in your portal, you can track live generation and long-term production totals per inverter unit without relying on Deye's cloud service.
Use cases
- Monitor live AC output power to verify each Deye Micro inverter is producing as expected under current irradiance conditions.
- Track cumulative energy yield over weeks and months to detect gradual performance degradation in individual panels.
- Compare power readings across multiple Deye Micro inverter units on the same roof to spot shading or fault outliers.
- Alert on zero-power readings during daylight hours to catch grid-disconnect events or inverter faults quickly.
