Product details
Introduction: Solar pumping system consists of solar pumping inverter, pump and PV array. Consider that storing water is more efficient than storing electricity, the system is designed to directly drive the pump without battery which can reduce the construction and operating cost and routine maintenance effectively. The PV array consists of multiple solar panels connected in series/parallel, which can supply the whole system as power source by converting the absorbed solar radiation energy to the electrical energy. Solar pumping inverter can implement the control of the whole system operation, which drives the pump by converting DC power produced by the PV array to AC power. This inverter can adjust the output frequency according to the solar irradiation intensity in real time to implement the MPPT (maximum power point tracking). The pump driven by a 3-phase AC motor draws water from deep-well or river. The pumped water is then fed into reservoir or water tank, or connected to the irrigation system or fountain system directly. All of centrifugal pump, axial-flow pump, mixed-flow pump and deep-well pump can be utilized. Features: 1. Compatible with 3-phase induction motor Water pump is driven by a three-phase AC motor; 2. It adopts dynamic VI maximum power point tracking(MPPT) and optimizes pure sine wave PWM control with fast response speed and good stability 3. Use stainless steel as protection material, so it can be installed outside without water-proof box; 4. Full automatic operation: according to the actual conditions, it can freely set the range of pump speed; 5. The main circuit uses intelligent power module(IPM) with high reliability and high conversion efficiency (above 98%); 6. Have complete protective functions (overload, over/under voltage, over heat, reverse polarity, thunder, over flow and dry running, short-circuit); 7. Protection degree IP65, working environment temperature: -10°C ~ 50°C; 8. LCD display(43*29mm), simple operation. setting parameters and fault detection ; 9. Solar pump inverter can connect to city power when there is no sunshine to keep system pumping water; This optional function is only for inverter whose power is less than 3.7kw. 10. Soft start and variable-frequency function.(Go up from 0Hz to 50Hz); 11.AC drive function.(When sunshine is not enough, AC city power is switched to work manually). 12. solar pump inverter has two main series: 1.solar pump inverter from 0.37kw to 5.5kw for 3-phase AC 220v pumps from 0.37kw(0.5HP) to 4.5kw(6HP); 2.solar pump inverter from 0.37kw to 75kw for 3-phase AC 380v/415v pumps from 0.37kw(0.5HP) to 65kw( 86HP). Application: 1) residents living water 2) irrigation 3) desert control 4) animal husbandry 5) water apply for sea island 6) livestock watering 7) water treatment projects,etc.
