Product Description
A complete solar Pump system consist of solar array, pump and solar Pump inverter. The inverter can convert DC power from solar PV array to AC power to run pump motors.

Solar array, an aggregation of many solar modules connected in series and parallel, absorbs sunlight radiation and converts it into electrical energy, providing dynamical water for the whole system.

Inverter controls the system operation and adjust the output frequency in real-time according to the variation of sunlight intensity to realize the maximum power point tracking (MPPT).

Pump, drive by 3-phase or single phase AC motor, can draw water from the deep wells or rivers and lakes to pour into the storage tank or reservoir, or directly connect to the irrigation system, fountain system, etc.
Features:
1.Apply to all kinds of single phase and 3 phase AC induction motor.
2.Equipped with TI DSP digital control technique and Infineon IGBT power integration module desion. 
3.Maximum power point tracking(MPPT) algorithm for dynamic VI.MPPT efficiency can be 99%.
4.Fast response speed and good stability.
5.AC and DC input available, but do not use DC and AC at the same time.
6.Remote control, support RS485 protocol.
7.Automatic sleep&awake function:
   1) auto sleep and awake according to the high and low water level in the tank respectively.
   2) auto sleep and awake according to the weak and strong sunlight respectively.
8. Full protections:Overload, over-current, over-voltage,under-voltage, short circuit, dry pumping, PV reversed connection protection.
