0.75KW 1.5Kw2.2Kw 4Kw Single Phase Output Mppt Solar Water Pump
Inverter For Ac Pump
Solar Pumping System description
The system is composed of a PV generator, a pump and a solar pump
inverter. Based on the design philosophy that it is more efficient
to store water rather than electricity, there is no energy storing
device such as storage battery in the system. The system is
prepared to be combined with a elevated water storage, e.g. water
tower or an uphill tank installation. The PV generator, an
aggregation of PV modules connected in series and in parallel,
absorbs solar irradiation and converts it into electrical energy,
providing power for the whole system. The pump drive controls and
adjusts the system operation and converts the DC produced by the PV
module into AC to drive the pump, and adjusts the output frequency
in real-time according to the variation of sunlight intensity to
realize the maximum power point tracking (MPPT).
Solar Pump Inverter Features
1. Input voltage from 150V DC to 450V DC drive single phase or
three phase 220V AC water pump.
2.Protection for overcurrent, overvoltage, overload, anti-lightning
etc.
3.Smart operation, water level detection and operation panel to
prevent overflow, dry pumping (optional).
4.Could drive both pmsm and im motor.
5.Start and stop automatically function.
6.Solar pump system includes solar panels arrays, solar pump
inverter and AC pumps.
7.Embedded pump-specific features such as dry run detection,
minimum power input protection, maximum current protection, stop
frequency running protection.
8.The drives can be equipped with remote monitoring options,
reducing maintenance trips to the site

Installation Environment Requirements:
1. Ambient temperature, the surrounding environment temperature
take great effect for service life span of solar pump inverter,
don’t allow surrounding temperature over than allowable temperature
above (-10°C to +50°C)
2. Heat dissipation, Install the solar drive on the surface of an
incombustible object, and ensure that there is sufficient space
around for heat dissipation. Install the solar pump inverter
vertically on the support using screws.
3. vibration, it should be less than 0.6G, far away from the
punching machine or the like.
4. Free from direct sunlight, high humidity and condensation
5. Free from corrosive, explosive and combustible gas
6. Free from oil dirt, dust and metal powder
