DC input, wide voltageworking voltage: (10v-22V). Built-in MPPT which can make the best use of the solar energy. The pump can be directly connected to solar panels in sunshine without controller.
Over-voltage protection / Under-voltage protection: The pump will stop working automatically when the voltage is too high or too low; Then it will detect the voltage every 10 minutes, and it will start to work automatically when the voltage is between the working voltage range of the pump. Environmental protection, achieve zero carbon dioxide emissions. Solved the water shortage problems of the area without electricity. Village or family water supply.Water supply for bivouac or camping car. Do not mix the positive (+) and negative (-) connection. Do not operate for long time when there is no water in the pump.
The pump is submersible pump, it must be full submerged in the water. PS: 6 mm² or 10 mm² copper wire is required when the cable length is too long. Package Weight: 4.000kg 8.82lb.Package Size: 12cm x 12cm x 48cm (4.72in x 4.72in x 18.90in). Note that the voltage of each pump and the maximum maximum flow of the head - assuming that the pump at the ideal voltage (12v pump for 18v, 24v pump for 36v) head when the maximum flow of 0, with the increase in the flow will gradually become smaller, The head is the maximum head when the head is 0 (in fact, our pump's maximum head and maximum flow are slightly larger than we announced). S screw pump features: power, low flow is relatively stable, the flow will not change with the head of a larger change and the head is higher, small size. M centrifugal pump Features: relatively more costly, low head when the flow is enough, but the head increases the flow will be significantly reduced, the higher the pump, the greater the size. 12v pump operating voltage range is 10v-22v, the best working voltage of about 18v; 24v of the pump voltage range is 18v-45v, the best working voltage of about 36v.
The performance of the DC pump is proportional to the input voltage of the pump (within the operating voltage range), but if the operating voltage is very close to the highest value of the voltage range, the life of the internal motor is reduced. Pressure drop: when the solar panel normal power generation, 12v board at no load when the output voltage of about 20v; 24v solar panel no-load voltage of about 40v, after the load (then the pump) voltage will be reduced, the degree of reduction according to the load pump The power of the change. Under normal circumstances it is recommended that customers use the pump power 1.5-2 times the corresponding (12v pump then 12v board, 24v pump then 24v board) solar panels.Note: This 1.5-2 is not fixed, according to the actual situation (work head, flow, light intensity) appropriate increase or decrease. The pump does not work. Check the positive and negative pump is reversed; the actual input voltage is how much to see whether the voltage in the normal range. In the use of the actual head is how much. (Actual head calculation as shown below). The length of the cable connecting the pump and the board (red line in the above figure), if the length is less than 40m, it is recommended to use standard 4mm2 pure copper wire, such as the length of more than 40m, the proposed use of standard 6mm2 or 10mm2 pure copper cable. Reason: the longer the wire, the more detailed, the cable itself consumes more voltage, resulting in pump input voltage is too low. Increase the input voltage or reduce the actual pump head. Check the pump inlet and outlet to see if there are dirt jam blockage (our pumps are currently water pump, if the long-term use of impurities in the water will cause impurities in the outlet outlet, and even the motor hold burning Bad). If the customer in the use of more impurities in the water can be recommended in the pump into the mouth of a layer of cloth to filter impurities. The pump beeps and stops after a few seconds. The actual reason: the board power is too small or the light intensity is insufficient, then the water pump, the board output voltage that the pump input voltage drops sharply (pump buzzer), down to the pump below the working voltage range when the pump automatically shut down after the pump stops To detect the voltage actually get the board no-load voltage, and the pump in the self-stop protection stage (5 minutes). Solution: Increase the power of the solar panel. Solar water pump system variables a lot of factors, such as problems should be fully considered. (Whether there are a lot of false cable), water pipe material, pipe resistance, horizontal distance, the water pump, the quality of the solar panels is stable, the specifications are standard (non-standard board is much cheaper than the national standard board), whether the virtual standard power; The quality of the actual performance of the pump have an impact.
