How to boost self-consumption with thermal storage

Electric water heaters for hydro-sanitary purpose can be easily employed to store the surplus energy produced by the solar PV system: this is extremely convenient to consistently improve self-consumption, thus reducing environmental footprint and energy bills.

Whi choose Power Reducer?

With Power Reducer the immersion heater used for water heating can be controlled in real time modulating the power absorbed, independently from the nominal power: this allows to use only the energy available produced by the solar PV system, without purchasing any energy from the grid.

How it works

Knowing the amount of surplus energy available from the solar PV system, Power Reducer modulates the electrical input, independently of the nominal power rating. Therefore, the user can exploit even only 100 Watt of surplus power, without purchasing any energy from the grid.

Thus, the energy consumption trend to heat water stays within the production curve of self-produced energy, without generating consumption peaks which are typical of other household appliances.
