GK200 Solar Pump Inverter in Water Supply SystemIntroduction
Energy and water saving irrigation is an important symbol of modern agricultural development, lack of electricity, less electricity in, no electricity, the power supply is not normal region, automatic water irrigation has been a very big headache problem. Even if the power supply can ensure the region's electricity supply facilities (including high voltage lines, transformers, power switches, etc.) are also large investment, high efficiency damage (including theft), the utilization of low infrastructure investment, especially in agriculture irrigation power facilities.
After the water supply system using photovoltaic solar cells directly convert solar energy into direct current energy, through a series of microelectronics and power electronics to convert DC to work after a three-phase AC drive pump. It is nearly 10 years to budding mechatronics worldwide high-tech products, which embodies the energy conversion, new motor, MPPT, frequency converter and a series of micro-electronics technology and software applications, and many other high-tech technology.
The principle of solar photovoltaic water systems
1) The system consists of solar arrays, solar pump inverter, transfer pumps and plumbing systems, water and reservoir water level detection devices;
- Solar cell array: convert solar energy into direct current;
- Solar energy converter: DC solar cells will be converted to a three-phase alternating current supplied to drive the pump work;
- Transmission system pumps and pipes: by pumps, pipes and ditches and other water sources of water will be delivered to the water or water storage areas;
- Water level detection device: detect water sources and reservoirs of water, protect the motor in the water supply to meet the requirements of the premise.

6) Solar water system works
Solar photovoltaic cell array through series or parallel, solar pump inverter, batteries meet the requirements of the DC power supply, inverter-driven water pump working again, pumping water from the reservoir, or other container, for life, livestock, agricultural irrigation, industrial production such as water. Water sources and reservoirs mounted liquid level detection sensor to detect water level changes. When the water level reaches the lower water level limit of the detection, or reservoir water level reaches the upper limit of the detection level, solar pump inverter promptly shut down can protect the motor and avoid wasting water.
7) The application principle of solar pump inverter
MPPT is the Maximum Power Point Tracking for short, MPPT controller can detect the real-time voltage of the solar panel power generation, and track the maximum voltage and current values (VI), the system with the highest efficiency of the battery, inverter capacitor charging. Solar pump inverter in photovoltaic system plays an important role in coordinating solar panels, batteries, workload, is an integral component of the PV system. Software unique MPPT algorithm to detect in real time via the controller solar panel power voltage regulator output frequency, fast dynamic response, the motor is always working at peak efficiency, so that the solar photovoltaic panels to maximize economic efficiency.
Solar photovoltaic energy conversion efficiency is impacted by the supply characteristics, factors such as light intensity and angle of the output voltage fluctuations, GK200 solar pump inverter wide voltage design is enable to ensure the inverter can still work normally under low voltage.
