Photovoltaic water lifting system (also known as photovoltaic water pump) is mainly composed of inverter, water pump and solar panel. It is the most powerful way of water supply in remote areas where there is a lack of electricity. By using the solar energy available everywhere and inexhaustible, the system automatically works at sunrise and stops at sunset. It does not need personnel to take care of it and has low maintenance workload. It is an ideal green energy water lifting system integrating economy, reliability and environmental protection benefits.
2、 Product principle
Photovoltaic array absorbs solar radiation energy and converts it into electric energy to provide power for the whole system. Photovoltaic water pump inverter converts the output DC of photovoltaic array into AC and drives the water pump, and adjusts the output voltage and frequency in real time according to the change of sunlight intensity to achieve maximum power point tracking. When the sunlight intensity becomes weak, the photovoltaic water pump system can realize the switching function of the city power, and the city power acts as the supplementary energy of the photovoltaic water pump system.
1. Full automatic operation: the photovoltaic water pump system is fully automatic operation without manual duty. The system is mainly composed of photovoltaic water lifting inverter, photovoltaic array and water pump.
2. No energy storage device: the system saves energy storage devices such as batteries, and uses water storage instead of electricity storage to directly drive the water pump to lift water.
3. Maximum power point tracking: photovoltaic water lifting inverter controls and regulates the operation of the system to achieve maximum power point tracking.
4. Full application of solar cell power: when the sunlight is sufficient, ensure the rated operation of the system; when the sunlight is insufficient, set the minimum operation frequency to meet the requirements, so as to ensure the full application of solar cell power.
5. Off grid work: without power supply from the grid, the solar array directly provides power for the whole system.
6. Different pumps can be used: the pumps can lift water from deep wells, rivers and lakes, inject water into water tanks / pools, or directly connect to irrigation or fountain systems. Centrifugal pump, axial flow pump, mixed flow pump, deep well pump, sewage pump and aeration pump can be used.
Photovoltaic water pumping system can be widely used in the fields of economic crops and farmland irrigation, barren mountain control, soil erosion protection, desertification and desertification land control, livestock and Grassland Irrigation, domestic water supply, infiltration and drip irrigation, sewage treatment, landscape fountain and so on.
Due to the off grid and convenient characteristics of photovoltaic water lifting system, it can play an irreplaceable role in the national implementation of "storing grain in technology" and extend the construction of high standard farmland from Pingchuan to mountainous areas.
Photovoltaic water lifting system also has strategic emergency function. When the State Grid is damaged by external forces and oil is cut off, photovoltaic water lifting system will be an indispensable emergency measure for people's life and all water industries.
