Solar Inverter Drive Water Pump Pumping Water

SETEC Power solar pumping system consists of solar pumping inverter, pump and PV array. Consider that storing water is more efficient than storing electricity, the system is designed to directly drive the pump without battery

Solar pumping inverter can implement the control of the whole system operation, which drives the pump
By converting DC power produced by the PV array to AC power. This inverter can adjust the output frequency according to the solar irradiation intensity in real time to implement the MPPT
(maximum power point tracking).


Setec inverter consisits of stainless steel shell, big aluminum heatsink for cooling, water proof fan, IPM from Mitsubishi ( intelligent power module ), so efficiency is 98%, very reliable.
Main board, LCD board, control board. All components we use good quality. Also we design a button for power on/power off.

Stainless steel shell, you can install our inverter outdoor directly. You can save money water proof box
We design a button for power on/power off. You can save money for AC breaker and DC breaker

Solar Pump Inverter functions:

1. Compatible with 3-phase induction motor Water pump is driven by a 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 and good stability; (Its MPPT controlling technology can adjust pump speed according to changes in sunlight intensity. In the peak of sunshine, the pump is running at rated speed, and the output power close to the PV array maximum power. When sunshine is insufficient, it will automatically stop working. );

3. The shell use stainless steel material, so it can be installed outside without water-proof box;

4. Full automatic operation: According to the actual conditions, it can freely set the range of pump speed;

5. The main circuit uses intelligent power module(IPM) with high reliability and high conversion efficiency (above 98%);

6. Have complete protective functions (overload, over/under voltage, over heat, reverse polarity, thunder, over flow and dry running, short-circuit);

7. Protection degree IP65, working environment temperature: -10° C ~ 50° C;

8. LCD display(43*29mm), simple operation. Setting parameters and fault detection;


9. Solar pump inverter can connect to city power when there is no sunshine to keep system pumping water;
This optional function is only for inverter whose power is less than 3.7kw.

10. Soft start and variable-frequency function. (Go up from 0Hz to 50Hz);

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

12. SETEC solar pump inverter has two main series:

SETEC solar pump inverter from 0.37kw to 100kw for 3phase AC 380v/415v pumps from 0.37kw(0.5HP) to 75kw( 100HP).
