FoxESS Modbus templates

FoxESS builds hybrid inverters and battery storage for residential and small-commercial solar installations. The templates in this library cover the H1 single-phase hybrid range, the three-phase H3-Pro/Smart series, the Avocado hybrid platform, and the MQ2200 product line — each split into PV, grid, and battery register groups so you get the measurements that belong together. Whether you install FoxESS on new-build rooftops or retrofit them onto existing PV arrays, these templates match the real register layouts the devices expose.

ModbusCloud reads your FoxESS inverter over Modbus RTU via the MCG-1 gateway on the RS485 bus and forwards PV generation per string, grid import/export, battery state of charge, charge/discharge power, and inverter status to the cloud portal. You get historical graphs, alerts on fault codes, and a remote console — useful when a customer calls about yield drop and the inverter sits an hour away. Because the FoxESS templates ship with correct scaling factors, installers skip the register hunt and focus on commissioning.

All 15 FoxESS templates are free to browse. Import the one that matches your model into your ModbusCloud portal and read live data within minutes — no register mapping, no manufacturer PDFs.
