1 - Introduction
To obtain the maximum level of service and sa-
tisfaction of our Solar Biocooler, please read this
manual carefully before installation.
2 - Warnings
Please read the warnings. They are listed for the
protection of people and the product. Neglecting or
ignoring these warnings can result in death or serious
injury and ends with the warranty. The system must be
installed by people with knowledge of electricity.
• The system must be installed and operated only by quali-
fied personnel. Make sure all power sources are turned off
when handling the installation wires.
• Prevent the control equipment from being exposed to di-
rect sunlight or other sources of heat.
• Install a ground system suitable for safety and protection
against lightning. A well-sized ground system can reduce
the chances of severe damage.
• Follow the recommendations for power cables. Undersized
cables may cause fan malfunction or even cable melting.
• To test, avoid joining wires to create spark. Use a multime-
ter to check the voltages.
• There are potential hazards when handling any heavy me-
chanical assembly. If you have questions about your ability
to perform manual installation safely, hire an installer. Do
not use a winch or a vehicle.
• In case of fire, notify the fire department of the existence of
photovoltaic installations.
3 - System
The Solar Biocooler is an air cooling unit, which
uses photovoltaic solar energy or mains electrici-
ty. For this purpose it uses 4 photovoltaic panels
(PV) and a monobloc frame with the necessary
elements.
Figure 1 - Solar Biocooler system scheme.
The photovoltaic panels provide energy for the Biocoo-
ler to function, however on cloudy days or during night
time, when there is less light, the power relay from the
mains can be activated.
If you do not wish to supply the mains power, you
must switch the cut-off switch on the switchboard off.
It should be noted that the supply of support must
be activated during the day, as the switching system
requires the 24VDC provided by the photovoltaic sys-
tem.
3.1 Technical characteristics
The Biocooler is an evaporative cooling unit that
allows to lower the temperature of the air by increasing
its humidity.
The model used can reach a pressure up to 194 pa
and an air flow up to 18000 m³ / h.
3.2 Monoblock with electrical equipment
The monobloc contains the essential equipment for
the operation of the system. This can be divided into
two subsystems depending on the power source, the
photovoltaic subsystem and the supportive supply
subsystem.
In the photovoltaic subsystem two equipments are pre-
sent; a voltage booster (DC BOOSTER) and a pho-
tovoltaic inverter (INV SOLAR1). It should be noted
that the voltage lift will provide a voltage of 440 VDC
to the inverter. This generates a three-phase voltage of
380V / 50 Hz and will power a second inverter (SO-
LAR INV. 2).
A power cut-off switch (BT) and a protective circuit
breaker (D) are present in the network support subsys-
tem.
Two contactors (K1, K2) are present for switching
between the two supply subsystems. There is an elec-
trical interlock to ensure that only one contactor is
actuated.

A transformer (TRAN) converts the 380 VAC (supplied
by the mains or the first inverter) to 230 VAC, needed
to power the control board, water pump and discharge
valve.
A second inverter (INV SOLAR2) is used to power the
“Biocooler” fan motor. This will receive two signals,
from the control board, to control the speed of rota-
tion.
Figure 2 - monoblock with electrical equipment.
Warning: On the outside of the electrical board door
should contain a warning signal about the existence of
two sources of energy, one of which is photovoltaic.
This signal is important for whoever installs and main-
tains the equipment.
To activate the photovoltaic system there is a se-
lector (S1) that starts the solar inverter.
Figure 3 - control selector of solar photovoltaic system.
• Turning the selector to “ON”, the solar inverter 1 is activa-
ted, powering the Biocooler with photovoltaic energy.
• When turning the selector switch to “OFF”, the
solar inverter 1 is deactivated, if it has power from
the network, the Biocooler will be powered by it.
Placed on the side of the electric panel is a cut-off
panel, which controls the mains supply.
Figure 4 - general network power cut-off panel.
Further information is given in annexes A and B, the
electrical diagrams are presented and a description of
the operation of the solar inverter is made.
It is also recommended to consult the operating ma-
nual of the Biocooler.
4 - Installation
To produce maximum energy, photovoltaic panels
should be properly aligned with the sun and clean (wi-
thout accumulation of litter or dust).
Panel performance improves with colder temperatures.
4.1 Location of photovoltaic panels
The photovoltaic panels should be installed in order
to maximize exposure to the sun. If necessary, the fan
panels can be separated.

5
However, the greater the distance, the greater the sec-
tion of electrical cables.
Caution: if there is shade on the PV panels there will
be a reduction in fan speed or even a stop. Any cell
that is shaded works as a resistor and reduces the
power of the entire PV array.
4.2 Solar Orientation
For better performance, care must be taken to ensure
the orientation of the photovoltaic panels.
In the installation one must look to orient the photo-
voltaic panels in relation to the equator line. (Northern
hemisphere - South direction), (Southern hemisphere
- North direction).
Small adjustments in the EAST or WEST direction do
not significantly affect system performance.
4.3 Inclination of the panels
Attention should also be given to the angle of inclina-
tion of the panels. In each season of the year, there
is a variation in the angle of solar incidence, which
affects the energy production.
In a simple way it can be considered that the inclina-
tion angle of the photovoltaic panels is related to the
latitude of the installation site. An adjustment can also
be made at the incline angle in order to maximize the
yield depending on the season:
• Ideal slope in summer: latitude -15º
• Ideal slope in winter: latitude + 15º
• Ideal year-round slope: latitude -5º
4.4 Distance between rows of panels
When placing the photovoltaic panels in rows; must
take into account the distance between rows to avoid
shading and consequent yield losses.
4.5 Support structure of photovoltaic panels
Caution: A structure designed to withstand wind, easy
to assemble, and most important, safe must be used.
You should follow good practices and defined care for
support structure.
Where roofs do not provide the sun exposure or incli-
nation necessary for the effectiveness of the system,
it may be assumed that it is installed at ground level.
Always consider minimum ground clearance, avoid
shading elements, observe safety conditions.
If you have questions about the structure of support
and display, consult a civil engineer with knowledge of
the site or companies dedicated to the installation of
photovoltaic panels. For better quality and economy,
factory racks are recommended.
5 - System Connections
All connections must be made by qualified personnel
in accordance with local laws, regulations and good
practice.
In order to make the connections, it is recommended
to consult chapter 6 (maintenance) and follow the pro-
cedures indicated therein.

Make sure that the cables are not in tension when
making connections.
Warning: Make sure you connect the cables of each
element to their terminals. Follow the signs.
Caution: Check the connections in the diagram shown
in this manual. Connecting the cables incorrectly can
damage the system. Use a multimeter to check polarity
and voltage.
5.1.1 Network connection
You must make sure that all phases and ground are
correctly connected. (It is not necessary to connect the
neutral conductor)
Figure 6 - Network cable indication.
5.1.2 Connection of photovoltaic panels
Warning: Photovoltaic panels can generate dangerous
voltages. A 48 V panel can generate close to 100 V
when it is disconnected from the load.
To avoid the risk of electric shock or damage to equip-
ment while working on the installation, cover the photo-
voltaic panels with opaque material (eg card) and leave
a cable off in order to interrupt the electrical circuit.

Figure 7 - Connection diagram of photovoltaic panels
The photovoltaic panels used to power the
Biocooler have a nominal power of 250Wp at
270Wp. They are connected in a parallel of two
series (positive terminal with negative) and can
produce about 76 VDC, open.
It is recommended to use MC4 type connectors
and suitable cable for photovoltaic installations
with UV protection, with a minimum cross-section
of 4 mm2. The greater the distance between the
fan and the photovoltaic panels the greater the
section should be, to avoid large voltage drops.
5.1.3. Biocooler links
In order for Biocooler to work in the right direction, you
must make sure to connect:
• The motor power cable to the respective motor terminals,
in the frame of the Biocooler (U, V, W), please check the
direction of rotation, if necessary change a phase;
• The power cable of the control board to the terminals of
the board, in the frame of the Biocooler (F, N, T);
• The motor speed signal cable to the signal terminals on the
Biocooler board (AV, BV, COM), together with the interfa-
ce relays.
Figure 8 - Identification of cables and terminals to be connected in the Biocooler.
5.2 Earth connection, lightning protection
Due to their exposure PV systems are subject to the
effect of direct atmospheric discharges or surges due
to indirect discharges in the vicinity of the installation.
Precautions should be taken to prevent or limit the da-
mage caused by them.
Caution: Local laws, regulations and good practices
for protection against direct and indirect atmospheric
discharges should be followed.
To mitigate the effects of indirect lightning strikes:
• Connect all metallic structural elements of the photovol-
taic panels to each other and the ground bus, in order to
create an equipotential bond between all the elements.
Proper grounding is important, allowing static electricity
to discharge to the earth - preventing lightning.
• It is recommended to use connecting conductors with a
minimum cross-section of 10 mm2 (copper).
• It is recommended that the conductive wires of the pho-
tovoltaic panels be put together in order to avoid inducti-
ve phenomena of indirect discharges.
• It is recommended that the elements of the photovoltaic
panels be separated from the atmospheric discharge
systems.
• It is recommended to use shielded cables in exposed
locations and / or over long cable distances.
If the building does not have a lightning protection
system, the support structure of the photovoltaic
generator must be connected to the ground bus
and incorporated in the equipotential bonding.
If there is a protection system against direct at-
mospheric discharges already implemented in
the building, all metallic structural elements of the
photovoltaic panels must be connected to it and
by the shortest possible path. The goal is to pre-
vent the beam from being able to directly reach
the photovoltaic module. The distance between
the photovoltaic generator and the shaft should
be greater than 2 meters in order to avoid lateral
discharge to the generator.
6 - Maintenance
Caution: All maintenance must be carried out by qua-
lified personnel in accordance with local laws, regula-
tions and good practice.
Each photovoltaic panel produces a voltage greater
than 35V, even without load. Care must be exercised
when handling all elements that are in contact with
their terminals.
On the electric panel will be a DC Booster that will
raise the photovoltaic voltage to about 440 Vdc. There
is danger of serious injury, even death. There is a war-
ning sign on the equipment.

7
Figure 10 - Hazard sign, voltage on photovoltaic panels.
Whenever maintenance work is required, all power
sources (photovoltaic panels, mains, etc.) must be
switched off or disconnected to avoid risk of electric
shock.
Make sure that:
• Turns off the equipment at the control;
• Turn off the disconnecting switches, the photovoltaic pa-
nels, the electricity grid, the equipment present;
• Cover the photovoltaic panels with opaque material (eg
card) and disconnect one of the power cables to ensure
that the circuit is interrupted.
