Product Introduction

ØThe JFY SPRING series solar pumping inverter is designed by the engineers who have been working in the solar inverter field
for many years, which has been studied for a long time and improved many times. Too many tests and verifications demonstrate
the SPRING solar pumping inverter’s outstanding performance. Now we are proud for this product and willing to promote it to you.

ØThe solar pumping inverter is mainly used in the areas where are lack of electricity or when the long distance power transmission
cost is too high; which is widely applied in 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 center squares, parks, tourist sites,
resorts and hotels, the landscapes and fountain systems in the residential areas.

ØSPRING solar pumping inverter is the core part in the solar pumping system. It can convert the DC power input into AC power
output, and supply necessary power to drive the solar pump to work. SPRING solar pumping inverter has many distinctive characteristics,
please refer to the following items.
