Electronic instrument for the control of active power self-produced by your
photovoltaic system.
If the power entered on the network (surplus of power, that is to say produced
power – consumed power) is higher than a programmed threshold (setpoint)
the SOLAR 3 provides for the connection of some loads that you can stop in
order to maximize the own consumption of the produced power. It’s possible
to control until 3 loads (or groups of loads) through the command of as many
relays, to whom is assigned a priority which sets the order with whom the loads
are connected.

SAFETY WARNINGS
During the installation and the operation of the instrument it’s necessary to
observe the following instructions:
1) The instrument must be installed by a qualified person by observing
scrupulously the connection diagrams
2) The instrument must be installed and activated in compliance with current
electric systems standards.
3) After installation, inaccessibility to the connection terminals without appropriate
tools must be granted
4) Do not use the instrument for other purposes different from the one specified
5) The instrument must be installed in a closed electrical panel adequately
protected
6) In the power supply network a bipolar disconnection must be present
7) A protection device against over-currents should be installed in the electrical
system, upstream of the device.
8) Before accessing the connection terminals, verify that the leads are not live
9) Do not power on or connect the instrument if any part of it is damaged
10) In case of malfunction do not perform repairs and contact immediately the
technical support
11) The instrument can be used in environments with category of measurement III
and pollution degree 2, as per standards CEI EN 61010-1.

The positioning of the current transformer is essential for the correct operation of the
instrument.
• The correct position of the current transformer within the electrical system is
shown in the picture 1
• The direction of the produced current (i) is shown in the picture 2 (incoming
current in the current transformer form the side indicated on the label)
• The current transformer must be connected to the terminals 8 and 9 of SOLAR-3:
- terminal 8: white thread
- terminal 9: black thread
Four loads or groups of loads must be located:
not disconnectable loads, that is to say the loads which are always connected
to the electrical line and which will not disconnect by SOLAR-3 if the production
of energy is lower than necessary (their consumption must be counted anyway by
SOLAR-3 to determine the total consumption)
connectable loads with priority 1, which will be connected for first if the surplus
of power is higher than the setpoint
connectable loads with priority 2
connectable loads with priority 3
The SOLAR-3 switches on with the disconnected loads; every seconds Delay On
one load is connected (if the surplus of power is higher than the setpoint).
During the normal operation the instrument shows the
surplus of produced power (expressed with two decimals)
and relays status (segment on fixed if disconnected load,
flashing segment if connected load)
The programmed setpoint can be showed for three
seconds by pressing the key .
Configuration relays (normally
open or normally closed) can be
showed by pressing the key
and then relays priority. Each
display is visible for 3 seconds.
The device reset can be performed by pressing simultaneously the keys
and : the loads are disconnected and then reconnected according to the set
priority.
DEFINITION AND MODIFICATION OF OPERATION PARAMETERS
• [kW] represents the activation threshold that is to say the minimum value of surplus of power so that the instrument provides for the connection of the loads Setpoint
according to the priority.
• Hysteresis (or differential) (kW) represents the value to subtract from the setpoint to determine the disconnection zone (that is to say the zone where the loads are
disconnected).
For example, if the setpoint = 3 Kw and differential = 0.5 kW the loads eventually connected are disconnected if the value of measured absorbed power is lower than 2.5 kW.
• Delay On [seconds] represents the minimum time which must elapse from the last connection (or disconnection) of one load before connecting another one. This time is
valid also at start-up that is to say , even if the surplus of power allowed, no load is connected before Delay seconds elapse from the switch on.
• Delay Off
[seconds] represents the delay of disconnection, that is to say how long the surplus of power must result lower than the
setpoint – hysteresis before the instrument
disconnects one load.
To access the modification or the operation parameters display press the key .

FW Versione Relays priority
Logic of relays operation Backlighting
To access the advanced programming press the key for at least3 seconds
This menu allows: the firmware version display, the modification of the logic of relays operation, the modification of relays priority, the setting of the instrument backlighting.
The output from the menu of advanced programming restarts the microcontroller. This means that the loads eventually connected are disconnected and then reconnected one at time every seconds (only if the power production allow this).Delay.On
It displays the firmware
version of the instrument.
Not modifiable field.
Normally closed (N.C.) (default setting)
deenergized relay,
disconnected load (used contacts: C, NA)
excited relay,
connected load (used contacts: C, NA)
Normally open (N.O.)
excited relay,
disconnected load (used contacts: C, NC)
deenergized relay,
connected load (used contacts: C, NC)
It allows to change the priority of relays outputs, that is to say the order with whom the loads are connected
and disconnected in case of surplus of power.
If not modified the priority is the following:
• OUT1 = P1 (the most priority output , that is to say the one which will be connected for first if the surplus of
produced power is higher than the Setpoint).
• OUT2 = P2
• OUT3 = P3
Attention: if by pressing the keys or you can’t go to the next menu (backlighting) or to the previous
menu (relays logic) it’s probable that the same priority P has been assigned to two different outputs OUT.
Correct by assigning different priorities to the three outputs.
It allows to set the backlighting:
• TIME = backlighting on
for 60 seconds
from the pressure
of one key
• NO = backlighting
always off
• YES = backlighting
always on
