Fronius Smart Meter TS 65A-3 Energy Meter Three-Phase 65 A Modbus RTU
The Fronius Smart Meter TS 65A-3 is a bidirectional three-phase direct-measurement meter for up to 65 A per phase, designed for Fronius inverters (Symo, Primo, GEN24 Plus). It is installed on a 35 mm DIN rail in the distribution board, close to the grid connection point, and takes up 3 modules according to DIN 43880.
It measures energy flows to and from the grid in real time and transmits them to the inverter via 3-wire RS485 with Modbus RTU protocol. This information feeds the consumption display in Fronius Solar.web, the dynamic self-consumption and load management, and the dynamic export limitation required by many grid operators. The enclosure has an IP51 protection rating, with IP20 terminals.
Key features
Direct measurement up to 65 ADirect connection on three phases and neutral, without current transformers, up to 65 A per phase.
Bidirectional meterRecords separately the energy drawn from the grid and the energy fed in by the photovoltaic system.
Modbus RTU over RS4853-wire serial connection to the Fronius inverter, 9600 bit/s, addresses from 1 to 255.
Data for Solar.webSupplies the inverter with the data needed to display generation, consumption and self-consumption in the Fronius portal.
Export managementEnables dynamic limitation of the power fed into the grid and intelligent load management.
3-module DIN formatSnap-on mounting on a 35 mm DIN rail, 3 modules wide according to DIN 43880, IP51 protection rating.
