2. Features of Three phase AC solar pump inverter
1), Wide MPPT range,tracking the max. power point to improve the efficiency of the Whole system.
efficiency is more than 99%.
2), With IP65 design, It can be installed outside with good waterproof.
3), Matching for any ordinary three phase 50Hz/60Hz pumps.
3), Full protection function can keep the system always in safe operation.
4), No need derate the power capacity for pump matching. The matching power with pump is 1:1.
5), Support Utility grid or generator work as pass by or complementary, working time 24hours per day
6), Three years warranty time.
7), Modular design,easy to install,operate and maintain.

4. Introduction of JNTECH AC Power Pack
AC Power Pack worked as power supplement during the whole Solar Water Pumping System, which allows the pump
to be powered by an AC generator or commercial utility power, besides of solar energy. Powerpack can keep the system
working 24 hours per day, and produce a great flow rate than you will see with only solar power.
The solar array remains connected. If the sun comes out again, less power is drawn from the AC source.
A common application is for diesel generator or unstable regions of utility grid. When the sun irradiation is insufficient,
just switch on the AC power source, which will work as supplement; And even at night, AC power source can work as pass by.
