Control Parameters (Power Reducer E4U ONLY)
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.
Set point:
Level of energy exchanged with the GRID acting on the controlled device
Valid values: - 30000 up to + 30000 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
- 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
+ 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

Advanced settings (Power Reducer E4U ONLY)
!
WARNING: Advanced parameters must be accessed for extra-ordinary and specific debugging operations ONLY.
The final user MUST NOT alterate these parameters for any reasons, since they control the algorithm operations
and can cause system crashes.
On the "Power Reducer Settings" page, it is possible to set the "Load" and "Set Point" values. It is also possible to tick the
option "Advanced settings", enabling the access to the following regulations:
Integration time:
Integration time of the regulation algorithm
Proportional constant:
Proportional parameter of the regulation algorithm
Integral constant:
Integral parameter of the regulation algorithm
Derivative constant:
Derivative parameter of the regulation algorithm

Default value: 1000 W
Default value: 0 W
The system amends the power aiming at "0" exchanged energy
The system adjusts the immersion power so that the system purchases 200 W
The system adjusts the immersion power so that the system sells 100 W
