System Introduction
Solar pumping system is composed of a solar array, a pump and a solar pumping inverter.The system is dispensed with energy storing devices, and stores water instead of electricity. It improves the reliability of the device, at the same time, it lowers the construction and maintenance costs of the system dramatically.
The solar array, an aggregation of many solar modules connected in series and in parallel, absorbs sunlight radiation, and converts it into electrical energy.
The inverter converts DC voltage from the solar array into AC voltage to drive the pump. With the function of MPPT(Maximum power point tracking), it regulates the output frequency according to irradiation in real time to achieve the maximum power.
The pump, driven by a 3-phase induction motor, draws water from wells or rivers, then pours water into the reservoir or storage tank, or directly to irrigation systems and fountain system. Based on the requirements and installation conditions, different types of pumps can be used.
Features of Solar Pumping Inverter:
1. To drive pumps equipped with 3-phase induction motors.
2. Optimized SPWM.
3. Various operation modes and MPPT algorithms are available.
4. Adjustable speed range of pump based on the actual situation of the system.
5. Available option of water-level detecting and control circuit.
6. Protection functions: lightning, over/low input voltage, over current and over load protection, etc.
7. Enclosure class: IP41 (Rated power below 18.5kW).
8. Ambient temperature-10~+50C.
Applied
Solar pumping systems can be applied to daily use (underground water), agricultural irrigation, forestry irrigation, desert control, pasture animal husbandry, water supply for islands, wastewater treatment engineering, and so on. In recent years, with the promotion of the utilization of new energy resources, solar pumping systems are more and more used in municipal engineering, city centre squares, parks, tourist sites, resorts and hotels, the landscapes and fountain systems in the residential areas.
