High Performance Mppt Hybrid Solar Pump Inverter Single Phase 750w 1.5kw 2.2kw 4kw

Short Description:

A complete solar pump system consist of solar array, pump and solar pump inverter. The solar pump 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.

Solar pump 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

Solar water pump inverter known as solar variable frequency(VFD) is used to control the operation of solar water pump system. It allows you to adjust output frequency as per intensity of the sunlight to achieve the maximum power point tracking(mppt). It is an off-grid type inverter. The solar water pump inverter does not depend on the power grid. It works with a water level control system. Solar water pump inverter can help save ample energy, with improve control, and require less maintenance due to nearly no wear and tear, offering reliable protection to the motor, and reducing stress on valves, pipework and other related systems.

With the maximum power point tracking, you get the best output power possible from solar panel, which increases the performance of the pump while auto start/stop can save your investment.

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 design.
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.
9. Widely used in agriculture and forestry irrigation, desert control, solar pasture irrigation, grassland animal husbandry, urban water supply and other landscapes.
