Solar Pumping Systems:

Solar pumping systems produced by Shenzhen Solartech Renewable Energy Company 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. The 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 storage battery in the system. The PV array, an aggregation of many PV modules connected in series and in parallel, absorbs sunlight radiation and converts it into electrical energy, providing dynamical power for the whole system. The pumping inverter controls and adjusts the system operation and converts the DC produced by the PV array into AC to drive the pump, and adjusts the output frequency in real-time according to the variation of sunlight intensity to realize the maximum power point tracking (MPPT). The pump, driven by PV array Pumping inverter Pump DC voltage 3-phase AC voltage Solartech Products Introduction 2 3-phase AC motor, can draw water from the deep wells or rivers and lakes to pour into the storage tank or reservoir, or directly connect to the irrigation system, fountain system, etc. According to the actual system demand and installation condition, different types of pumps such as centrifugal pump, axial flow pump, mixed flow pump or deep well pump can be used. 1.2 Product Features Based on many years of development and experiment, the self-developed pumping inverter by our company has the following features: Features: Adopting the proposed dynamic VI maximum power point tracking (MPPT) control method which has independent intellectual property; Fast response speed and stable operation; Better than the conventional methods which may lead to the problems including poor tracking performances, unstable operation or even damaging water hammer effects when the irradiation on the array changes rapidly.  Digital control with full automatic running, data storage and complete protective function  Intelligent power module (IPM) for the main circuit with high reliability.  New design of aluminum alloy case, LED display operating panel, in-line blocks; user friendly; convenient for operating; perfect cooling and shielding.  Option of up and down water level detection and control circuit is available.  Protection level IP52;  Ambient temperature for using
