SETEC Power solar pump inverter system is designed to directly drive the pump without battery but can reduce th econstruction and operating cost and routine maintenance effectively.

This inverter can adjust the output frenquency according to the solar irradiaion intensity in real time to implement the MPPT (maximum power point tracking).

This device widely used in domestic water, irrigation water, control of desert, animal husbandry, water supply for Sea Island, water treatment projects, etc. Water storage replaces battery and directly drives pumping, with high reliability, at the same time, it can reduce system cost and maintenance costs. Water pump is driven by three phase AC inverter. Pumping water from the deep well or rivers and lakes is poured into the water tank/pool, or directly connect irrigation system and fountain systems. According to actual demands and installation conditions, there are various water pumps to choose, such as centrifugal pump, mixed-flow pump, deep-well pump.

Instead of generating electricity to turn a motor, sunlight can be concentrated on the heat exchanger of a Stirling engine and used to drive a pump mechanically. This dispenses with the cost of solar panels and electric equipment. In some cases the Stirling engine may be suitable for local fabrication, eliminating the difficulty of importing equipment. One form of Stirling engine is the fluidyne engine which operates directly on the pumped fluid as a piston. Fluidyne solar pumps have been studied since 1987 ^[5] At least one manufacturer has conducted tests with a Stirling solar powered pump.

 

Product feature:

1. Water pump is driven by three-phase AC motor;

2. It adopts dynamic VI maximum power point tracking(MPPT) and optimizes pure sine wave PWM control ,with fast response speed, good stability;

3. Full automatic operation, according to the actual conditions,it can freely set the range of pump speed ;

4. The main circuit uses digital power module,with high reliability, high conversion efficiency of 98%;

5. Have complete electrical protective function, it can choose water level detection and control circuit, to prevent overflow and dry well;

6.Protection grade IP65, working environment temperature: -10°C ~ + 50°C.

7.No need bettery(water storage replaces battery power storage)

8.Starting box is not required

9. LCD display, simple operation. setting parameters and fault detection

10.Low voltage drive function( LV40-70 special DC - DC converter converts 39V-100V to 280V-420V to drive solar pump system,which reduce the cost of solar panels and danger of DC high voltage)

11.AC drive fuction.(when sunshine is not enough ,AC city power is switched to work manually)

Product Advantages
