Company introduction: 

KEWO ELECTRIC TECHNOLOGY CO., LTD. ( hereinafter called KEWO ) is a professional manufacturer of kinds of AC drives, variable frequency inverter, soft start, and solar pump inverter, etc. We are not only focus on designing, manufacturing, sales and after sales service for above mentioned products, but also providing custom made automation solution and renewable energy technologies.

There are more than **0 staffs working in our factor, *0% of them are engineers. Thanks to KEWO R&D team hardworking and continue innovating, we master core and leading vector control technology for PMSM and IM controlling. We also introducing latest servo motor technology from Italy and Japan that help us keep top competition in China. We have established 2 modernization production lines, digital quality control system, code bar tracking system and ERP management system, etc. And every piece of KEWO products have been tested with full load to ensure **0% good quality. Quality begins and ends with each person in our company. 

KEWO products is comprised of high level AC drives, variable speed drive, frequency inverter, solar pump drive with DC and AC , etc. These products are widely using in industrial automation, cement, textile, metallurgy, HVAC, oil &gas, water treatment, chemical , machine tools, hoisting, agriculture, farming, irrigation…



Fully automatic system using variable speed drive compatible with AC, *-phase, submersible and surface mount pumps, and high efficiency PMSM Pumps. The system is composed of a PV generator, a pump and a solar pump drive. Based on the design philosophy that it is more efficient to store water rather than electricity, there is no energy storing device such as storage battery in the system. The system is prepared to be combined with a elevated water storage, e.g. water tower or an uphill tank installation.



KEWO Solar Water Pumping Solution is a fully automatic system designed to provide water at affordable cost for people with limited or no access to electricity. It uses the most advanced S**0/***0 variable speed drive to regulate the speed of a *-phase AC motor depending upon the solar energy available from the solar panel.



How does it work ?

An arrays of solar panels generates the power and voltage required for the SG**0/***0 Solar inverter to drive the motor. The solar drive converts the DC voltage to a *-phase AC output with variable voltage and frequency. The MPPT algorithm of solar drive extracts maximum power available from the solar panels during the day and operates the motor at variable speed based on the power to the drive. The frequency range in which the drive operates depends upon the motor speed, hydraulic system and the power available from the solar panel. As the sunshine varies during the day, power to the drive varies and the Solar drive generates variable V/F ratio thus controlling the speed of the motor, which in turn regulates the pump impeller speed. Water Level Sensor is used only when the water is pumped to overhead tank. 



Benefits

• Pumping of water in for irrigation for drinking water supply in off grid areas, easy installation. 

• Farmer can cultivate multiple crops through out the year in off grid areas 

• Farmer can save their time spent in collecting and transporting water.

• Lower operation expense compared to diesel pumps 

• Zero emission of green house gases.

• Reduced load on national grid. 

 



Applications

Irrigation of land, domestic water supply, fish farming, livestock, swimming pool, fountain, drip irrigation & sprinkler, industrial application, swimming pool…
