Université de Tlemcen. Cependant l accès à l électricité est devenu primordial pour un développement équilibré et constitue un facteur important de l exode rural. C est donc un défi de mettre d une part à la disposition des populations rurale et désertique une source d énergie capable de stimuler l activité économique et de conduire des améliorations dans leurs besoins quotidiens. Ainsi, il est temps de semer la culture des énergies renouvelables dans notre pays. Le travail est réalisé à la station de : Algérienne des Energies Renouvelables située à Chlef. Il consiste à dimensionner un système de pompage photovoltaïque sur le site en utilisant deux méthodes : une analytique et l autre graphique lissée par la méthode numérique des moindres carrés.

Before you begin: All pump systems are equipped with nameplates, which contain all important data. Check the model numbers of all the components of your system, verify that they are the items that you ordered and ensure that the packaging is undamaged and complete. To allow best system performance and to avoid damage read and follow the installation instructions carefully. How to use this guide: This manual is for system installation only, follow it closely for a safe and durable installation.

The system layout must be planned beforehand. SITES provides an easy overview of all installed pump systems, including serial numbers and installation details. This will be essential information should problems occur and will simplify trouble shooting and warranty topics to great extent.

PumpScanner will also assist in the day to day operation of the PS2 controller and add value to your customers. If you do not have access to a Play store in your country, please download the app from Important information about use of PumpScanner can be found on page Further information on use of PumpScanner including detailed functions and installation are available in the PumpScanner manual on partnernet.

Installation Overview This installation overview is provided to familiarize you with the typical steps that are taken when installing a solar water pumping system.

Your particular installation may require the steps to be done in a different order. You should read the whole manual before making your first installation. This information is provided in the manual included in the container this device was packaged in.

It should be retained with this device at all times. A hard copy of this information may be ordered at where the manufacturer s phone number is provided. Read and follow the manual carefully to ensure reliable operation and long life of the product and to avoid danger to health and life. Every PV installation must be equipped with a PV disconnect switch.

Install the controller close to the PV array in a shaded location to minimize cable length on the input side. For detailed information refer to 7. Observe rotation direction. Accessories wiring: Connect a source low protector to terminals 1 and 2 required. Remote control switches must be connected to terminals 3 and 4, water meters to terminals 5 and 6, 4 20 ma sensors to terminals 7 and 8 or 9 and 10, water sensors to 13, 14 and 15 and the SunSensor module to terminals 16 and Terminals 11 and 12 are an output relay switch.

Observe max. If the controller is connected to a battery then battery mode must be activated in PumpScanner. Grounding: A protective earth connection must be wired to the earth connector below the pcb. For detailed information refer to Pump Wiring on page For detailed information refer to Pump Accessories Wiring on page For detailed information refer to Input Wiring for Solar-direct Systems on page For detailed information refer to Grounding on page Pump Installation Submersible pumps: Lower the pump into the water source with caution, use a safety rope.

Surface pumps: Install the surface pump on an adequate foundation with sufficient pipe sizing to ensure efficient operation. Fill the pump with clean water prior to starting it.

For detailed information refer to 8. Depending on your pump system, refer to 8. If any abnormity is found, contact your supplier. LORENTZ pumps are supplied from the factory in proper packing in which they should remain until they are to be installed at the site. Handle the pump with care and avoid unnecessary impacts and shocks. Prolonged intermediate storage in an environment of high humidity and fluctuating temperatures must be avoided.

Moisture condensation may damage metal parts. Non-compliance can void the warranty. It is recommended storing the parts in a closed and dry room. The components should not be exposed to direct sunlight. They are typically used in irrigation projects and for wide area drinking water applications where they reliably meet the most demanding requirements, economically, without pollution and without a grid connection or diesel generator.

A typical solar pumping system is composed of a PV generator array, a pump and a solar pump controller. Based on the design philosophy that it is more efficient to store water rather than electricity, there is no energy storing device such as a storage battery in a typical solar pumping system.

The PV generator, an aggregation of PV modules connected in series and in parallel, absorbs solar irradiation and converts it into electrical energy, providing power for the whole system. The pump controller controls and adjusts the system operation and adjusts the output frequency in real-time according to the variation of sunlight intensity to realize the maximum power point tracking MPPT.

This modular concept keeps all electronics above ground even for submersible pumps, simplifying servicing and lowering cost of ownership. Versions and approvals requirements will vary from country to country. Please see the actual controller labelling to confirm exact version and approvals marking. Full approvals certificates can be found on partnernet. When the temperature reaches the limit the power will be reduced automatically.

The PS2 controller is designed for use in environments classified as pollution degree 3 in accordance with IEC Conductive pollution occurs, or dry non-conductive pollution, which becomes conductive due to condensation, is to be expected. The max. Defects due to pumping other liquids are not covered by the warranty. When used in salt and sea water pools, the pump must be inspected and cleaned regularly.

The water must not contain any abrasive particles. It is highly recommended to install an intake strainer to protect the pump from any dirt ingress.

Please refer to Filtering on page 54 for further information. PS2 helical rotor HR submersible - Designing and building helical rotor pumps for a narrow range of fluid temperature is important to ensure the best possible efficiency. The temperature class is part of the pump units name tag, please refer to chapter 3. The pump system shall only be operated within the temperature range specified upon ordering. These recommendations are based on prior experience of local water impurities and particulates within the water.

Indicates that the marked item may be hot and should not be touched. Refer to the operating instructions When installing and using this electrical equipment, basic safety precautions should always be followed, including the following: WARNING To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.

Pressure losses - Loss of water pressure due to pipe length and friction caused by pipe material and additional pipe line elements like elbows, valves. For solar water pumping additionally local irradiation levels are necessary to calculate the available power during each day and the effect on water output. It is based on NASA weather data and uses precise algorithms for even the most complex calculations.
