Wattmeter smart meter TS 63A for Fronius Three-Phase

The Fronius Three Phase Wattmeter, model Smart Meter TS, is a device used to measure the energy at the main entrance to the house, in order to know the consumption of electricity that can supply the photovoltaic installation. Thus, the wattmeter communicates with the Fronius single-phase, grid-connected and hybrid inverter, so that it can adequately adapt the output energy to the battery charge if any and / or consumption.

With the measurement of instantaneous electricity consumption and communication via MODBUS RTU, the logic of the Fronius inverter can limit the power output to the maximum of the actual consumption of the house at that moment.

It is an element that allows us, if we so wish, not to discharge surplus solar electricity production to the grid to which we are connected. It is also useful to measure the need for electricity we have, so that, added to the fact that the inverter knows the amount of power we produce, we can have a comparison between energy generated and energy required.
