Modbus RTU
Deye String inverter (pv)
Deye
Overview
The Deye String inverter (pv) is a grid-connected photovoltaic string inverter used in residential and commercial solar installations. This ModbusCloud template reads the two core production registers over Modbus RTU: instantaneous output power at address 86 and cumulative generated energy at address 63. Connecting the ModbusCloud Gateway to the inverter's RS485 port delivers live and historical PV yield data directly to your portal, giving installers and site owners a reliable baseline for yield verification and fault detection.
Use cases
- Monitor instantaneous PV output power to verify the inverter is producing within its rated range.
- Track cumulative energy generation daily and monthly to produce yield reports for building owners.
- Alert on a sustained drop in output power during daylight hours to detect shading or string faults early.
- Compare energy totals across multiple Deye string inverters on the same site to identify underperforming units.
