4-noks Power Reducer SA: stand-alone control device to maximize self-consumption, storing hot water with hot water tank or heat pump.

4-noks Power Reducer control unit uses the solar PV system to produce hot water for sanitary use and heating, thus significantly reducing gas bills.
 
When water is heated using an electric element (such as in a water heater or a storage cylinder), it can happen that the supply of energy effectively needed to operate the heater at full power may not always be available.
Thanks to Power Reducer technology, this is not a problem, since the device is able to divert only the energy available from the PV system to the heating element, exploiting even as little as a few hundred watts, without EVER drawing power from the grid.
 
It is suitable for hot water storage tank/electric immersion heaters rated up to 3.0kW; Power Reducer allows a significant improvement in self-consumption.
Power Reducer SA is equipped with a built-in energy meter that provides the facility of producing hot water without ever drawing power from the grid. Connected to a water heater / storage tank with an electric immersion element rated up 3.0kW, Power Reducer SA can deliver immediate savings.

Main functions

• Modulates power absorbed by the heating element
• Maximum load: 3.0 kW @ 230Vac 50Hz
• Boost function: 100% activation of load, irrespective of how much power is available from PV energy production. This function can be used to force the production of hot water (with a weekly timer if so desired), for example to meet an increased requirement, or during a particularly rainy winter period.

• Easy to install: no plumbing skills required
• Safe: compliance with EC and EMC regulations for residential and commercial use

• 70A current transformer included for calculation of available energy

Available versions

There are three models of Power Reducer available, to meet different installation and operating needs:

• Power Reducer / Power Reducer RC to be combined to the Elios4you system, for a complete management from the App
• Power Reducer SA stand-alone version, for solar PV systems without monitoring system

Power Reducer can be connected to:

• Water heater to produce hot sanitary water
• Storage tank for thermal storage
• Heat pump to heat water activating only the integrated heating element
