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.

•

Insulation: reinforced between accessible parts (front panel) and all other terminals

• Type of actions: 1B

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
