Power Reducer

Free hot water from solar PV energy

Product Description

How it works

The Power Reducer is a control device which, when combined with Elios4you, provides the facility of producing hot water by maximizing the use of surplus photovoltaic energy generated on site, without ever drawing power from the grid.

It is suitable for hot water storage tanks / electric immersion heaters rated up to 3.0 kW. Connected to the Elios4you controller by a cable, the Power Reducer allows the system to divert and route surplus PV power automatically to the immersion heater, without drawing electricity from the grid, even when no more than a few hundred Watts may be available.

Main features

  • Modulates power absorbed by the load, exploiting available PV energy without drawing power from the grid
  • Easy to install: no plumbing skills required
  • Safe: compliance with CE and EMC regulations for residential and commercial use
  • Configuration and control provided directly by “Elios4you” free App
  • Max rated power of electric heater 3kW @ 230V
  • Connection with cable to Elios4you controller
