We recommend the installer/user to carefully read the instructions and information included in this manual before starting to use the product, so as to avoid damage, improper use of the appliance or cancellation of the provided warranty. The manufacturer declines whatsoever responsibility in the event of accidents or damage due to negligence or failure to follow the instructions contained in this manual or to use in conditions other than those indicated by the rating plate. It also declines whatsoever responsibility for damage caused by improper use of the electric pump. Do not subject to weights or other packages when packing.
DESCRIPTION OF THE SYSTEM
The FLUID SOLAR pumping system has been devised to pump clean water from a
well making use of energy produced by photovoltaic panels to fill a tank.
The electronic control integrated in the brushless motor converts the output
voltage from the panels and regulates the motor rotation speed so as to
exploit the energy delivered by the panels to the maximum: on a sunny day the
rotation speed will be elevated with high pump performance, while on a cloudy
day the speed will be reduced. The motor has an integrated control logic that
stops the pump from switching on when the solar radiation is too low for it to
operate correctly. The panels are connected in series forming strings. Each
string is connected to the control panel through a suitable connection cable.
The pump is connected to the control panel through a connection cable put
together with the pump power cable by means of the resin joint. The whole
plant is connected to ground.
(Fig. 1 FLUID SOLAR with P1=750 W) or (Fig. 2 FLUID SOLAR with P1=1500
W).
SAFETY
Before carrying out any control or maintenance activities, switch off the
plant power supply.
Avoid contact between the electric power supply and the liquid to be pumped.
The FLUID SOLAR electric pumps are not suitable for pumping flammable liquids
or for operating in areas subject to explosion hazard.
Do not modify the electric pump components. Never support or transport the
electric pump by its power supply cable. The FLUID SOLAR electric pumps must
not be used by children or people with reduced physical, sensorial or mental
capacities, or lacking experience and knowledge, unless they have been
instructed and supervised correctly. Children should be kept under control to
avoid them playing with the appliance.

faults in question.
CONDITIONS OF USE
The electric pump must be used respecting the following conditions:
- Maximum liquid temperature: +35 °C
- Maximum liquid density: 1 kg/dm3
- Liquid Ph: 6÷8
- Maximum sand content in the pumped liquid: 150 g/m3
- Maximum submersion depth: 40 m
INSTALLING THE ELECTRIC PUMP
The appliance must be installed by a competent and qualified installer.
When installing the electric pump apply all safety regulations issued by the
competent authorities and dictated by common sense, do not underestimate the
drowning hazard if the pump has to be installed in a well with a considerable
depth.
Ensure that:
- there is no hazard of toxic exhalations or poisonous gases in the working environment;
- in case of welding all necessary precautions to avoid explosions are taken;
- the well dimensions are suitable for containing the pump and that the characteristics of the water to be pumped are compatible with the data described in the conditions of use;
- the well capacity is adequate to the hydraulic performance of the pump;
- the pump installation depth is sufficient to ensure that it is submerged during operation, the pump running dry will be subject to serious damage;
- the pump is always supported by an adequate stainless steel cord fixed at one end to the holes provided on the fluid delivery body and at the other end on the well lid;
- the pump power supply cables are fixed with plastic cable ties every 2 – 3 metres along the fluid outlet piping.
INSTALLING THE PHOTOVOLTAIC PANELS
To select the photovoltaic panels follow the indications below:
- the no-load voltage of each string must range between 70 and 100 VDC and can be obtained by connecting more panels in series, a high no-load voltage (but always lower than 100 VDC) guarantees better pump performance;
- the current on each module should be lower than 6A : In case of more modules installed in series and in parallel, total current towards the board should never exceed 25A;
- to guarantee optimal electric pump operation, the overall power delivered by the installed photovoltaic modules must be at least 960 Wp for FLUID SOLAR with P1=750 W and 1920 Wp for FLUID SOLAR with P1=1500 W;
- installing photovoltaic modules with an overall power above 960 Wp for P1=750 W or 1920 Wp for P1=1500 W guarantees maximum pump performance for a longer period throughout the day. The increase in power must be obtained by adding more panel strings in parallel. The no-load voltage delivered to the control panel and motor must not be above 100 VDC.
When installing the photovoltaic panels apply all safety regulations issued by
the competent authorities and dictated by common sense; do not underestimate
the fall hazard if the panels have to be installed on a building roof.
The panels can be installed both on the ground or on a building roof. It is
the responsibility of the installer to install the photo-voltaic panels in
compliance with the regulations in force in the country in question. The
panels must be adequately fixed to a metal structure protected against
corrosion. This structure must be adequately anchored to the ground or to the
building where the installation is being carried out. For maximum performance
the panels must point SOUTH and be inclined with respect to the horizon by an
angle depending on the latitude of the installation location. An installation
pointing SOUTH with a 30° angle allows good performance in most applications
(for installations in the SOUTHERN hemisphere we request the positioning of
the photovoltaic panels towards NORTH). Ensure that the panel surface is not
obstructed during the day or as seasons change by shade caused by trees or
other buildings in the vicinity of the installation.
To guarantee the efficiency of the panels in time regularly check their
surface conditions and if necessary clean them.
ELECTRICAL CONNECTIONS
The various system components must be positioned so as to reduce the length of
connections to the minimum. For the electrical connections between the
photovoltaic panels, the control panel and the electric pump use cables with a
4 mm 2 section with an overall length up to a maximum of 40 m, or 6 mm²
section cables with a length up to 80 m, or 10 mm2 section cables with a
length up to 180 m.
The connection cables going from the panels to the control panel must be
prepared with the special insulated and watertight connectors supplied (Fig.
6), or with other connectors compatible with those on the photovoltaic panels
used. The cables employed connect the various system components and must be
resistant to UV rays. Otherwise a specific protection must be fitted.
The panels can deliver a voltage up to 100 VDC, before carrying out any
operation on the plant, cover the panel surface with a cloth to protect the
panel surface from direct sunlight, then disconnect the panels from the rest
of the plant.
Pay maximum attention when making the connections linking the panels and the
electric pump to the control panel: a connection that does not respect the
correct +/- polarity can damage the control panel or the electric pump.
Joint the pump cable with the connection cable to the control panel using the
resin joint.
While carrying out the junction conform to the instructions included in the
resin joint.
The maximum no-load voltage delivered by the strings of the photovoltaic
modules (<120 VDC) allows the system to be classified as a low-voltage safety
plant (SELV type).
Connect the pump protection conductor and the ground conductor coming from the
ground plate to the control panel terminal (Fig. 8). Where there is no ground
plate, make it by planting a galvanized steel stake in the ground (Fig. 1 e
Fig. 2).
INSTALLING AND USING THE CONTROL PANEL
Install the control panel so that it is not directly exposed to the elements
(rain or direct sunlight). If it is installed in a closed area this must be
suitably ventilated and with an ambient temperature ranging between +40 °C and
-5 °C (Fig. 7).
The control panel is arranged to receive the power supply from 2 strings of
panels, that are connected in parallel inside the control panel, powering 1
electric pump. It is fitted with a programmable NO or NC input for controlling
the electric pump by means of a free contact (for instance a float) (Fig. 8).
To start the pump select by means of buttons and “START” and press ,
confirm by selecting “YES” with and press. After 10 seconds the pump
starts.
To switch off the pump select by means of buttons and “STOP” and press ,
confirm by selecting “YES” with and press .
To visualise the voltage trend in time select by means of buttons and
“WIEW” and press . By pressing again you visualise the absorbed current
and power. Use buttons and to modify the visualised time interval and
buttons and to modify the visualised scale dimension.
To set up the protections and other panel operating options select by means of
buttons and “MENÙ” and press .
Setting up the maximum current and the minimum and maximum voltage
protections: by means of the buttons and and select “GENERAL SETUP” and
press .
If PANASONIC mod VBHN240SJ25 photovoltaic modules are employed carrying out
settings is not required as the correct values have been pre-set in the
factory. Otherwise the following settings must be made:
- MIN VOLTAGE OFF: this is the minimum no-load voltage delivered by the modules, below which the control panel does not power the pump (we advise a value equivalent to 90% of the no-load voltage powering the control panel).
- MIN VOLTAGE ON: this is the minimum voltage delivered by the modules with the pump running, below which the control panel cuts off power to the pump (we advise a value equivalent to 75% of the no-load voltage powering the control panel).
- MAX VOLTAGE: this is the maximum voltage delivered by the modules above which the control panel cuts off power to the pump (we advise to set a value equivalent to 105% of the no-load voltage powering the control panel).
- MAX CURRENT: this is the maximum value of the current absorbed by the pump (we advise to set the value indicated by the pump rating plate).
- MAX CURRENT TIME: this is the maximum time a current above the MAX CURRENT value is tolerated; when this time is up the control panel shuts down the pump.
Set up the abovementioned parameters with the buttons and select the item to
be modified and press accordingly. The current value is shown; press the
buttons and to modify the value and then the button to confirm and view
another item.
Setting up the input contact: by means of the buttons and select “EXTERNAL
SETUP” and press .
-
LEVEL 1 INPUT: set on ON if you wish to use a float to start or stop the pump, set on OFF if you wish to control the pump manually.
-
LEVEL 1 TYPE: set on N.O., if, with the contact enabled, you wish to start the pump when the contact closes or set on N.C. if you wish to start the pump when the contact opens.
-
LEVEL 2 INPUT: set on ON if you wish to use a float to start or stop the pump, set on OFF if you wish to control the pump manually.
-
LEVEL 2 TYPE: set on N.O., if, with the contact enabled, you wish to start the pump when the contact closes or set on N.C. if you wish to start the pump when the contact opens.
Please note that when LEVEL 1 INPUT and LEVEL 2 INPUT are both enabled in ON, both contacts must be enabled to start the pump (mode of operation in AND). -
STOP DUE TO DRY RUNNING: setting of the pump stop mode due to dry running.
• To set the required mode of operation in the control unit select “MENU” using the and buttons and press . Then select “EXTERNAL SETUP” using the and buttons and press .
• Select “NO WATER AUTO” using the and buttons and then select “ON” using the and buttons and press (this function is normally “OFF”).
– If the above illustrated function is enabled, when the pump enters dry running, it evaluates the circumstances for 30 seconds (“Dry” will flash on the display), after which the pump enters the stop phase.
– The pump tries to re-start after 300 seconds. If it is still in dry running, it will try again after 600 seconds. It will then try again after 1200 seconds, after 2400 seconds, after 3600 seconds and so on every 3600 seconds if the circumstances are the same, until the end of the day when the pump switches off together with the solar panels.
– The following morning it will repeat everything.
– If during one of the attempts to re-start, the pump resumes operating with water (not anymore dry with air) for a time longer than 30 seconds, the cyclical re-start contactor is re-programmed with the initial value of 300 seconds.
MAINTENANCE
Before carrying out any maintenance work, ensure that the voltage is
disconnected and that there is no risk of accidental connection.
Having the pump repaired by personnel that has not been authorised by the
Manufacturing Company causes the cancellation of the provided warranty besides
operating unsecure and potentially dangerous equipment.
ATTENTION: any form of tampering may lead to a reduction in performance and danger for persons and/or things.
