Product Overview
Power Reducer is a load diverter designed to automatically divert the excess energy produced from a PV system to a
resistive load, such as an immersion tank, rather than exporting to the GRID.
There are 2 different versions of Power Reducer, which provide 2 distinct modes of controlling the diversion of the
surplus generated energy.
Stand Alone
The Stand Alone version comprises of the Power Reducer SA and a Current Transformer (CT). The CT detects the en-
ergy exchange with the GRID and in particular the energy ow directions. Thus it distinguishes when the household is
drawing energy to satisfy consumption or exporting when the PV system is generating surplus to requirement.
Elios4you
This second version of the Power Reducer provides the measurements and commands that are managed through Eli-
os4you and its mobile application interface with dedicated graphics.
Elios4you features 2 Current Transformers (CT), one to detect the energy exchanged with the GRID and the other to
monitor the energy generated by the PV installation. The mobile application interface allows detailed understanding of
the PV system and a more rened control over the generated power by means of the Power Reducer (E4U)
Both versions of the Power Reducer perform the same basic functionality, which is to divert surplus generated power to
a resistive load such as the immersion tank even when this surplus power is less than the rated power required by the
resistive load. The Power Reducer accomplishes this feat by modulating the load to force it to operate at the lower rating
in a continuous manner over time, thus avoiding the need to import energy for this load from the GRID.
Example: Supplying a 1700W resistive load with say a 400W surplus from the PV system. In this case the Power Re-
ducer will warm the resistive load with just 400W avoiding any drawing of the 1300W of power from the GRID which
would normally take place without the Power Reducer.

System Requirements
The electrical load (immersion) connected to a Power Reducer has to be a pure resistive load that does not exceed the
related power of Power Reducer itself (3kW).
(E4U ONLY) The rmware version installed on the Elios4you TOP must be V1054 build 72 or higher. The
system can not work properly with older rmware versions. Check the version from the App in the “Update” menu. If
necessary, update the App by clicking “Update App via 4-Cloud”. It is then suggested to select “Install Firmware” to
update the device with the latest rmware version from App.
(E4U ONLY) It is necessary that the installation of Elios4you is completed correctly before proceeding with
the installation of Power Reducer. Verify the orientation of CTs (Current Transformer) and the correct wiring of Elios4you.
Make sure that the App shows the proper values of the system energy ows, making sure that the Elios4you LEDs diagno-
sis conrms the ows of energy represented by the graphics. For further information, check the Elios4you documentation.

Installation4
Warning: The wiring MUST be carried out by a qualied technician.
Warning: Connect the device to a line adequately protected against short circuits and heat overloads in excess of
the applicable maximum rated power.
Warning: Connect the device as set out by local regulations.
Warning: Do not perform any wiring while the device is powered up.
4.1 General instructions
4.2 Positioning
When choosing where to install Power Reducer, you must consider the following factors:
a) location of the power cable of the immersion
b) recirculating air
c) (E4U ONLY) distance between Power Reducer and Elios4you
The length of the 0-10V connection cables between Power Reducer and Elios4you must not exceed 10 meters.
0-10 V max 10m
230 V ~ 230 V ~
Power Reducer shares the same power source as the resistive load. Install the Power Reducer along the path
followed by the cable of the immersion.
Power Reducer must be positioned in an area with adequate ventialtion, in order to have a an efcient cooling
system. As far as possible, choose open areas with windows, avoiding closets or narrow spaces.

4.3 Ventilation
It is very important to provide good ventilation to the
Power Reducer to facilitate effective control of the
operating temperature of the device. To do this, it is
necessary to install Power Reducer vertically, posi-
tioning the cable downwards.
Ensure that there is adequate spacing around the
Power Reducer (minimum of 7cm) in particular the
top and bottom for adequate ow of air.
MIN 7 cm
MIN 7 cm
4.4 Mounting
Power Reducer can be mounted xing it to the wall with 4 screws (not supplied). The size and type of screws have
to be suited to the weight of the Power Reducer and the type of wall.
WARNING: Do NOT use the Power Reducer directly as a template for the holes. This use may damage the device
beyond repair. Utilise the template attached at the end of this document.

User operation (Power Reducer E4U ONLY)8
When the “Power Reducer” mode is activated, you can select between 3 different modes of operation through the Eli-
os4you App ( Menu / System Settings / Peripherals - DAC Mode - Power Reducer ).
Find below a brief description of the modes:
Automatic (recommended):
Power Reducer activates after passing the “Set Point” value
Off:
The immersion connected to the Power Reducer is turned off.
Boost:
The load connected to Power Reducer is forced to operate according to the parameters set (% of power and
duration) without considering the actual energy generated from the PV system and the energy exchanged
with the GRID.

Press the “Ok” button and
then the house-shaped button

Power Reducer widget.
Click the button to open

Select among the 3 available
modes the option that ts bet-
ter the end-user needs.
now the widget displays the
power that is diverted to the
Power Reducer.
When the “Boost” mode is

tinue.
There are some differences in
what is shown by the widget
according to the mode selected:
1. Value that shows the energy diverted to the Power Reducer
2. The colour of the bar is now yellow (Boost Mode) instead

Control Parameters (Power Reducer E4U ONLY)9
Accessing the Power Reducer Menu settings, from Eios4you App it is possible to set the following Control Parameters:
Immersion:
Load power controlled through the Power Reducer
Valid values: 0 - 3000 W. Default value: 1000 W
Set point:
Level of energy exchanged with the GRID acting on the controlled device
Valid values: - 30000 up to + 30000 W. Default value: 0 W
0 W: setting this value, the system tries to use only the energy generated from the PV system by varying the
power supplied to the immersion. This is the solution where self consumption is optimized.
E.g.: Set Point = 0 The system amends the power aiming at “0” exchanged energy
- xxxx W: setting a negative value, the system is forced to consume more energy than the amount of energy
generated. In this way, the lack of energy is compensated by energy purchased from the GRID and the im-
mersion operates at higher regimes.
E.g.: Set Point = - 200 The system adjusts the immersion power so that the system purchases 200 W
+ xxxx W: setting a positive value, the system reduces the energy consumed, so that is lower than the energy
generated. The excess energy is sold to the GRID and the immersion operates at lower regimes.
E.g.: Set Point = 100 The system adjusts the immersion power so that the system sells 100 W
!WARNING: Advanced parameters must be accessed for extra-ordinary and specic debugging operations ONLY.
The nal user MUST NOT alterate these parameters for any reasons, since they control the algorithm operations
