Fronius Smart Meter TS 65A-3 – 42.0411.0345

The Fronius Smart Meter TS 65A-3 is a three-phase, bidirectional meter with direct measurement, designed to accurately measure the energy consumed, generated and fed into the grid. It is the key component for turning any Fronius installation into a truly smart system: it allows you to optimise self-consumption, monitor loads and apply dynamic power limitation in real time via Modbus RTU (RS485).

Features of the Fronius Smart Meter TS 65A-3 – 42,0411,0345

• Real-time bidirectional measurement: controls energy import and export with complete transparency.
• Optimised self-consumption: the inverter adjusts production/battery according to actual consumption.
• Dynamic zero discharge: faster and more precise regulation than S0 systems thanks to Modbus RTU.
• Detailed load curves: ideal for detecting consumption peaks and sizing batteries or loads.
• Visualisation in Fronius Solar.web: comprehensive monitoring via the Fronius Solar.web app.
