Fenecon Modbus templates

Fenecon builds energy management and battery storage systems for homes and commercial sites, built around the open-source OpenEMS platform. The templates here cover Fenecon Home, Fenecon Mini Ess, Fenecon Dess (including its grid meter and PV meter modules), Fenecon Commercial and Commercial40 (including the CHARGER and MasterBox2V0 Relay), plus the generic OpenEMS interface. That range reflects how Fenecon appears in the field: residential energy storage, commercial multi-cabinet installations, and integrator builds on top of OpenEMS.

ModbusCloud reads your Fenecon system over Modbus TCP and surfaces the energy data OpenEMS exposes — grid power, PV meter readings, battery state of charge, charge and discharge power, and relay states on the MasterBox2V0. For installers running multiple sites, the portal consolidates them into one overview with alerts on grid import spikes, battery stuck at low SOC, or PV meter dropouts. Because each Fenecon variant has its own template with the correct register addresses, you skip the OpenEMS register-channel translation that usually eats a commissioning afternoon.

All 14 Fenecon templates are free to browse. Import the one that matches your system into your ModbusCloud portal and read live data within minutes — no register mapping, no manufacturer PDFs.
