Deye Modbus templates

Deye builds PV inverters across the residential and small-commercial range, including the SUN 12 hybrid, the three-phase hybrid inverter line, the storage (hybrid) inverter range, plus string and micro inverters. The templates here cover each product family and split them into PV, grid, and battery register groups where applicable. Installers find Deye on rooftop solar jobs both as a greenfield choice and as a hybrid retrofit where storage is added to an existing PV array on a single platform.

ModbusCloud reads your Deye inverter over Modbus RTU through the MCG-1 gateway on the RS485 bus and surfaces the operational data: PV generation per string, grid import and export, battery state of charge, charge and discharge power on hybrid and storage models, and inverter status. The Deye SUN 12 template also supports control registers, so you can not only monitor but send basic commands through the portal. Alerts flag grid export loss, SOC stuck at the low-limit, and reported inverter fault codes across the Deye fleet.

All 9 Deye templates are free to browse. Import the one that matches your inverter into your ModbusCloud portal and read live data within minutes — no register mapping, no manufacturer PDFs.
