I. Introduction
The Solar pumps allow you to extract water in areas, where aren't mains supplies, but with directly
transformation of solar energy into electricity.
Please read and apply herewith given instructions, so you can use the Cranes' solar pumps full
capacity. In case you don't observe them, this might result in personal injuries and product damages.
The present instructions are giving information about the safety measures, which should be undertaken
during the time of delivery and installation of the solar pumps, together with the technical instructions,
which should be followed while installing, mounting, wiring and maintaining.
Please keep these instructions during the whole service life of the solar pump. Read and observe very
carefully herewith given instructions.
The product warranty will be invalid if the written instructions for mounting and solar pump exploitation
are not complied with.
II. Important safety instructions
1. Strict observance of the installation instruction and solar pump exploitation are obligatory!
2. Do not use a part from the equipment or whole equipment set for activities which are not subject
of the exploitation instructions. Otherwise Crane Ltd or/and its representatives will not be held
under liability for damages, loss or injuries caused from the product to persons or movable and
non-movable property caused because of non-observation of the exploitation instructions
3. The right maintenance and exploitation ensure optimum result and long service life of the solar
pump.
4. Never instal the solar pomp on places in near vicinity of children or animals.
5. Do not use abrasive chemicals for cleaning of any part of this product.

Centrifugal pump
Screw pump

1. There is a three-phases brushless motor built in the pump, who directly drives a screw (for a
screw pump) or a turbine (for centrifugal pump) and has passed a special control test.
2. The motor is with simple and reliable construction, small volume and small weight.
3. The special double-plastic technology for motor encapsulating makes it suitable to be used
under water, as its insulation resistance exceeds 500 MegaOhms. The motors' bearings are
water-lubricated, which excludes a need of other lubricating materials (such as oils and
greases), which might be thrown in the water. This protects the environment.
4. The controller is especially designed to work with this type pumps, supplied trough photovoltaic
modules as it has built in МРРТ (maximum power point tracker), which moves the pannels
working point and as this extracts the maximal possible power. The built in protections from
short-cut, over-voltage and overheat protects the controller as well as the pump from damages.

IV. Guidelines for installation and exploitation of solar pumps
Photovoltaic module (PV) selection
1. Operating principle:
The photovoltaic module converts the solar energy into electric energy (DC) → DC electric
energy enters into the controller → the controller stabilize the voltage, charges the accumulator
(option only for model 3TSS1,38) and produces voltage that conforms the pumps motor → the
pump extracts water
2. Solar pump system's advantages:
a. Much easier and more widely used than any other electrically driven pumps
b. Economic and environment friendly, because of renewable energy source usage.
3. Photovoltaic module(s) and accumulator selection
a. The PV module power is necessary to be selected in a way of being 30% or more than the
power consumed by the pump. The PV voltage must comply with the pumps' operating voltage
and the maximal voltage of the controllers' inlet.
b. The number of the accumulators used depends from the selection that we made about the
accumulators' voltage and the voltage of the pump. The voltage needed for a certain pump is
formed trough serial connection of the accumulators. The accumulators capacity should be
selected in accordance with the pumps' power and the time during which the accumulator can
supply the pump without being discharged under the threshold. It is not recommended to
connect accumulators in parallel connection to increase the total capacity, especially in
the cases when the accumulators are with different capacity!!!

Serial
* if 2 or more PV modules are to be connected –please pay attention about the way of the connection
A. If you connect 2 or more PV modules in series, the voltage in the 2 ends of the circuit will be equal to
the voltage of one module multiplied with the panels number, and the current will be equal to the current
of one module.
B. If you connect 2 or more PV modules in parallel, the current of the whole circuit will be equal to the
current of one module multiplied with the modules number, and the voltage will be equal to the voltage
of one module.
C. The connection of photovoltaic modules with different parameters is not recommended!!!

Cable terminal scheme
Mode selection
I: Mode photovoltaic panel
0: Switched off
II: Mode accumulator
Scheme and connection sequence
a). Open the package and check the controller for transport damages
b). Please set the switch in mode “switched off” position “0” before connection
c). Connect the controller as it is shown on picture 1
1. Connect the pump (be careful for the polarity U,V,W)
2. Connect the photovoltaic modules in series scheme to X+ and X-
3. Connect the accumulator to Y+ and Y-
4. Connect the level sensors to TC, TH, WC, WL, WH

WARNING
1. After the first pump start, it will work about 2 minutes, then the controller will provide self-test for
about 30 seconds and will restart the pump.
2. If you wish full accumulator charge, please select mode “accumulator” position “II” and stop the
pumps' work (there are 2 possibilities of doing it:: 1> outer reservoir (if there is such) to be full'
2> to switch off the sensor of terminal WC.
3. Limit voltage values of open loop for photovoltaic modules:
