Brief introduction:
Solar pumping system is composed of a solar array,a pump and a solar pumping inverter. Based on the design philosophy that it is better to store water than electricity , there is no energy storing device such as storebattery in the system. The solar array,an aggregation of many solar modules connected in series and parallel , absorbs sunlight radiation and converts it into electrical energy , providing dynamical water for the whole system. The pumping inverter controls and adjusts the system operation and converts the DC produced by solar array into AC to drive the pump , and adjust the output frequency intensity to realize the maximumpower point tracking (MPPT) . The pump, drive by 3-phase AC motor,can draw water fromthe deep wells or rivers and lakes to pour into the storage tank or reservoir , or directly connect to the irrigation system ,fountain system,ect. According to the actual systemdemand and installation conditions,different types of pump such as centrifugal pump, axial flow pump,mixed-flow pump or deep-well pump can be used.
Main feature:
•Adopting the proposed dynamic VI maximum power point tracking (MPPT) control method ; Fast response speed and stable operation; Better than the conventional methods which may lead to the problems including poor tracking performance,unstable operation or even damaging water hammer effects when the irradiation on the array change rapidly.
•Digital control with full automatic running, data storage and complete protective functions (overload, over voltage,under voltage,over heat, reverse polarity, thunder, over flow and dry running).
•The main circuit adopts intelligent power module (IPM), with high reliability and high efficiency 98%.
•Unique design of aluminum alloy with good cooling and shielding , LCD display (43*29mm) and keys , easy operation , good view through LCD when setting parameter, feel comfortable.
•Protection degree IP41,working temperature: -10～+50℃
•Inverter connects to city power when there is no sunshine to keep system pumping water is available (optional).
•Low voltage drive device is our patent right product, can be used in small solar pumping system to save the quantity of solar panels.
