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 ef 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.

4OPERATION
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
