Carlo Gavazzi Modbus templates
All 5 available Carlo Gavazzi templates for ModbusCloud.
Monitor Carlo Gavazzi EM-series single-phase and three-phase energy meters via Modbus RTU and Modbus TCP.
Carlo Gavazzi is an Italian-Swiss automation vendor whose EM-series energy meters are installed across PV self-consumption sites, commercial sub-metering, and industrial MCCs. The 5 Carlo Gavazzi Modbus templates in our library cover the EM111 single-phase meter, the EM24 three-phase energy analyzer with Modbus TCP, two revisions of the three-phase EM340, and the EM540 three-phase meter, mixing Modbus RTU and Modbus TCP connectivity.
With ModbusCloud and Carlo Gavazzi templates you read per-phase voltage, current, active/reactive power, power factor, frequency and imported/exported active and reactive energy. The EM340 template exposes reset registers for partial and total energy counters and a configurable demand-integration time window. The EM540 supports phase-to-neutral and phase-to-phase voltage readings, useful for PV inverters that require both line configurations.
All 5 Carlo Gavazzi templates are free to browse. Import one into your ModbusCloud portal to meter the grid side of a PV installation or bill tenants based on sub-metered active energy.
