Huawei builds PV inverters, battery storage, and site controllers for residential and commercial solar. The templates here cover the SUN2000 hybrid inverter (both standalone and in combination with a LUNA2000 battery and DTSU666-H smart meter), the EMMA home energy manager, and the SmartLogger site controller, each split into PV, grid, and battery register groups. That mirrors how Huawei systems are usually commissioned: a SUN2000 with LUNA2000 at home, or a SmartLogger aggregating multiple inverters on a commercial roof.
ModbusCloud reads your Huawei system over Modbus TCP — direct to the inverter, to the EMMA, or to the SmartLogger — and surfaces the data installers actually need: PV generation per string, grid import and export via the Smart Power Sensor, LUNA2000 state of charge, charge and discharge power, and inverter status. Because the template for SUN2000 plus LUNA2000 plus DTSU666-H is pre-wired with the correct register offsets, you avoid the classic trap of reading the wrong device slot on the Huawei bus. Alert rules flag grid export loss and battery faults reported in the status registers.
All 12 Huawei templates are free to browse. Import the one that matches your installation into your ModbusCloud portal and read live data within minutes — no register mapping, no manufacturer PDFs.
