Vfd solar inverter pump drive

2.2 KW solar water pump inverter

Solar Pumping System overview

The solar pumping 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). The pump, driven by 1/3-phase AC motor, can draw water from deep wells, rivers and lakes and pour it into storage tanks or reservoirs, or be connected directly to the irrigation system, fountain system, etc. According to the actual system demand and installation condition, different types of pumps such as centrifugal pump, axial flow pump, mixed flow pump or deep well pump can be used.

Solar pump system constitution. It includes solar panels arrays, solar pump inverter and AC pumps. Dual supply mode - Dolar DC and Grid AC Compatiable input.

Main Features of solar pump inverter

Maximum power point tracking (MPPT) with fast response speed and stable operation efficiency> 99%; Suits for most 1 phase AC pumps and AC PMSM high efficiency pumps. The working voltage of solar panel can set by manual or MPPT automatically tracking Compatible with dual power input, AC grid and DC power supply input. Built in automatic sleep-wake up function, Dry run (under load ) protection Motor maximum current protection Low input power protection Lowest stop frequency protection The PQ (power/flow) performance curve enables calculating the flow output from the pump Digital control for fully automatic operation, data storage and protective functions Intelligent power module (IPM) for the main circuit LED display operating panel and support remote control Low water probe sensor, and water level control function Strong lightning protection
