LOADS CONTROL 1 RELAY FOR ENERGY PRODUCTION

Read all the instructions carefully

Insertable

load

Electronic instrument for controlling the self-produced active power of

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 set threshold (setpoint) for a settable period of time (Ton), the SOLAR-1

Micro switches on the load connected to the relay, in order to maximize the

selfconsumption of the power produced.

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) The instrument can be used in environments with overvoltage category III

and pollution degree 2, according to the CEI EN 61010-1 standard.

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 5 and 6 of SOLAR-1 Micro (respect the polarity):

- terminal 5: white thread (+)

- terminal 6: black thread

Two loads or groups of loads must be identified as follows:

• not disconnectable load, that is the load which is always connected to the power line and which will not be released by the SOLAR-1 Micro

if the energy production is lower than necessary (its consumption must in any case be counted by the device to determine the total consumption).

• insertable load, which will be connected if the power surplus is higher than the setpoint.

information to users pursuant to art. 14 of the directive

2012/19 / EU of the european parliament and of the council

of 4 july 2012 on waste electrical and electronic equipment (WEEE)

If the crossed-out bin symbol appears on the equipment or packaging,

this means the product must not be included with other general

waste at the end of its working life.

The user must take the worn product to a sorted waste center,

or return it to the retailer when purchasing a new one.

Products for disposal can be consigned free of charge (without any new purchase obligation)

to retailers with a sales area of at least 400 m

2, if they measure less than 25 cm.

An efﬁ cient sorted waste collection for the environmentally friendly disposal of the used device

or its subsequent recycling, helps avoid the potential negative effects on the environment

and people’s health, and encourages the re-use and/or

recycling of the construction materials.

DEACTIVATION OF THE CONTROL

It is possible to disable relay switching which normally occurs

when the intervention threshold is exceeded.

• To enable this function, regulate the

Ton trimmer to the maximum value and

verify that the green LED flashes.

• To restore normal operation, reset the

Ton trimmer to the desired value

(and in any case lower than the maximum value)

and checking that the green LED is steady on.

DEFINITION AND MODIFICATION OF OPERATION PARAMETERS

• [kW] represents the activation threshold that is to say the minimum Setpoint

value of surplus of power necessary for connect the load

• (or differential) (kW) represents the value to subtract from the setpointHysteresis

to determine the disconnection zone (that is to say the zone where the load is

disconnected). This value can be set higher than the setpoint value.

This setting of SOLAR-1 Micro allows the use of all self-produced power and the use

of the remaining power from the low voltage grid.

• Ton [seconds] represents the period of time in which the power must be above

the setpoint before the load is actually switched on.

During this phase the red LED flashes.

Example 1: if the setpoint = 3 kW and differential = 0.5 kW the load eventually

connected is disconnected if the value of measured absorbed power is lower than 2.5 kW.

Example 2: if the setpoint = 3 kW and differential = 4 kW the load eventually connected

is disconnected if the value of measured absorbed power is lower than“-1 kW”

(1kW taken from the low voltage network). In this way the load will use all the

self-produced power and the power of 1 kW from the low voltage grid.

1 Terminals for load connection

2 Trimmer for setting the threshold (Set)

3 Trimmer for setting the release threshold of the load (Hyst)

4 Trimmer for setting the delay before inserting the load (Ton)

5 Terminals for voltage and current inputs

6 Signaling LEDs:

- green for power supply

- red for exceeded threshold indication

7 Toroid for the measurement of the current produced by

the system of generation net of the one absorbed by the load
