2 Introduction Congratulations on the purchase of your Solar Pool Pump from North American Solar Solutions. Solar powered products are environmentally friendly, self-sufficient as well financial benefit to reduce rising electrical cost. Our product range is designed with durability and reliability in mind to provide trouble free service throughout the life of the product. Our Solar Dc Pumps can be used for: Agriculture Pool applications Water pumping needs Water Fountains Care and disclaimer It is recommended that you familiarise yourself with these important instructions. Read the complete manual before commencing the installation. Although the solar panel connections are considered low voltage, there is still a possibility of electrical shock. During the connection stage of the solar panels, it is recommended that the panels be covered with dark cloth or cardboard until connections are complete and you are ready to carry out voltage tests. Do not switch the power on unless all connections and voltage readings are correct. The pump leaf basket must be filled with water before attempting to start the system. Failure to comply will void warranty Page 2

3 Installation Details Solar photovoltaic panels convert sunlight to electrical energy which is fed to the solar controller. Using MPPT (Maximum Power Point Tracking) technology, the solar controller maintains constant voltage and converts the single phase DC to 3 phase DC to power the pumps 3 phase DC motor. Sizing the solar panel array to suit the system If you have not purchased a complete system from your Certified Distributer the following formula will be useful. Your certified distributer will be able to help you with panel selection. The optimum loaded DC voltage (Vmp) for the solar controller is between 35VDC to 80VDC. The maximum open circuit voltage (Voc) is 100VDC. CONNECTION OF SOLAR PANELS WITH TOTAL OPEN CIRCUIT VOLTAGE GREATER THAN 100VDC WILL VOID WARRANTY. FOR: NASS 500, NASS 750, NASS 1000 TOTAL OPEN CIRCUIT VOLTAGE GREATER THAN 400VDC WILL VOID WARRANTY. FOR: NASS 2200 &NASS 2200X Page 3

4 Solar Panel Requirements: Recommended Power of PV panels (watts) = Rated power of pump (watts) x 1. 3 ~ 2.0 Example: One Nass 500 pump Power = 500 watt pump needs a minimum of 500 watts multiplied by 1.3 to maximum 2.0 to drive the DC motor (500w x 1.3 = Minimum Panel wattage required 650w) Optimum 1,000 Watt You may need combinations of series and parallel connections of panels, especially for the larger pumps. The required voltage is achieved by connecting the solar panels in series (series string). The total power requirement (watts) is achieved by connecting further series strings in parallel. Panels in series; add the voltage and the wattage of the panels. Example 2 x 36 volt, 8 Amp 200 watt panels in series becomes a 72 volt 8 Amp 400 watt system. Panels in parallel; add the current and the wattage of the panels. Example 2 x 36 volt, 8 Amp 200 watt panels in parallel becomes a 36 volt 16 Amp 400 watt system Page 4

6 Solar Controller Function and display of the solar pump controller: Low-voltage protection (automatic) Over current protection (automatic) Control of motor running speed (speed regulator) MPPT function (Maximum Power Point Tracking) The row of LED s at the top of the controller have the following meanings L.E.D. Operation Explanation Power Solar Power Green Power is within specification Pump Running Green - Pump Running condition starts 6 seconds after Power L.E.D status is Green MPPT Maximum Power Point Tracking Green The Controller is calculating the MPPT Well Water available When using for water pumping to reservoir use sensor to sensor if water is available. If using for pool pumping connect bridge between WC & WH. Led must be lid else pump doesn t start. TANK Identifies if reservoir is full When pumping to reservoir and level sensing is required connect sensor to TC & TH. Light will lid when reservoir is full. Page 6

8 Testing the pump Once all connections to controller and the pump are complete, and voltages and polarity have been confirmed, FILL LEAF BASKET reservoir with water then the pump can be started: 1. Switch Internal controller switch ON The pump has a soft start function and will start slowly after 6 seconds and then spin up to full speed within the next 6 seconds. NOTE: Looking at the motor from the back (fan) the motor should spin clockwise. If not, turn power off, swap the wires on U and V, turn power on and check again. Do not allow the pump to rotate anticlockwise or the pump and / or motor will be damaged and warranty will be void. If the motor continues to spin backwards, turn everything off and call for service advice. NOTE: Once installation is complete the internal ON/OFF switch will remain ON and the isolator will be used as the main ON/OFF switch. Do s and don ts Do be careful with wiring Do put your solar PV panels in a sunny position facing true north (southern hemisphere) or true south (northern hemisphere). For best results tilt the panels at an angle equal to your latitude. Don t run the pump dry, even momentarily, as warranty will be void. Don t use the pump in dirty and or contaminated water. Premature wear will not be covered by warranty. Don t disassemble the controller. There are no user parts inside. Do s Strainer basket to be cleaned to prevent the pump from water starvation Do s Install spark arrestor for high voltage spike Do s Install appropriate AC breakers for panels & battery bank Page 8

It is during 30mins delay after water level sensor protection from low water level in well. Please restart the switch on/off on controller. Water level in tower is lower than TH sensor, but the indicator light of TANK_F lights on. 1. Disconnect TH wiring terminal and TC wiring terminal. Then if TANK_F lights off, it means the problem may be caused by short circuit of the water level sensors. Please change the water level sensors. 2. Please check if there is any other metal material in tank that is lower than TH sensor. If yes, remove the metal material. 3. If TANK_F still lights on, please contact with your supplier. Water level in well is higher than WH sensor, but the indicator light of WELL_L lights off. 1. Connect WH wiring terminal and WC wiring terminal directly with a piece of wire to get a short circuit. Then if WELL_L lights on, it means the problem may be caused by open circuit of the water level sensors. Please change the water level sensors. 2. If WELL_L still lights off, please contact with your supplier. The indicator lights flicker continuously, and water pump does not run normally It may be caused by the low input voltage. 2. Please increase the input voltage. 3. If the lights still flicker, please contact with your supplier. Page 13
