EC620 SERIES FOR PV/SOLAR WATER PUMP
EC620 SERIES FOR PV/SOLAR WATER PUMP
EC620 is a special inverter for solar / photovoltaic water supply which is developed based on EC6000 series. It has a rich and comprehensive application functions to meet the needs of various applications of photovoltaic water supply system.This EC620 solar pump drive product is widely used in Middle East countries, India, Turkey, African countries and regions. Because the local water conservancy system is not developed, it is necessary to pump water from the ground and store water in tank (water pool) to achieve the purpose of farmland irrigation. At the same time, the dry land with abundant solar energy just meet the application environment requirements of our EC620 product.
