Fully automatic system using variable speed drive compatible with AC, 1 /3-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.
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 S300/3200 variable speed drive to regulate the speed of a 3-phase AC motor depending upon the solar energy available from the solar panel.
Descriptions and Features 1. Maximum power point tracking (MPPT) with fast response speed and stable operation efficiency> 99.6% 2. Suits for most 3 phase AC pumps and AC PMSM high efficiency pumps 3. The working voltage of solar panel can set by manual or MPPT automatically tracking 4. Compatible with dual power input, AC grid and DC power supply input 5. Built in automatic sleep-wake up function 6. The PQ (power/flow) performance curve enables calculating the flow output from the pump 7. Digital control for fully automatic operation, data storage and protective functions 8. Intelligent power module (IPM) for the main circuit 9. LED display operating panel and support remote control,LCD display coming soon. 10. Low water probe sensor, and water level control function
