Solar AC Pumping System

ÿ¯Solartechÿ?solar pumping system is composed of:


A solar array, a solar pumping dedicated integrated inverter&controller, and a 3phase AC pump at different power up to 45KW.



How does works:

The solar array is composed of many solar cells panels in series and in parallel, and absorbs irradiation from Sunlight, and converts into electrical energy (DC). Inverter controls and regulates pumping operation system and converts DC voltage from PV modules to AC to drive the AC pump, with the function of MPPT and it regulates the output frequency according to irradiation in actual time to achieve the maximum power. The AC pump driven by a 3 phase induction motor, draws water from well or rivers and lakes, then water reserved on tank/ponds for irrigation systems or other applications. Based on the requirements and installation conditions, different types of pumps will be required.



System features:



ÿ¯Solartechÿ?Solar pumping system adopts the proposed dynamic VI maximum power point tracking (MPPT) control method; Fast response and stable operation; Better than the conventional methods which may lead to the problems including poor tracking performances, unstable or even cause water hammer damaging when the irradiation on the array changes rapidly. Based on the concept of developing environmental and economic products, 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:


1. Optimized SPWM. 98% conversion rate from the panel to the pump.
2. Various operation modes and MPPT algorithms are available.
3. Adjustable speed range of pump based on the actual situation of the system.
4. Available option of water-level detecting and control circuit, auto running.
5. Full protection functions: thunder protection, over/low input voltage protection, over current and over load protection, dry running and blocking protection etc.
