If you are seeking for photovoltaic inverter for solar powered water pumping system, then you are already arrived to the right store. Our SI20 series solar powered pump inverter is definitely the appropriate choice for you.

Veichi SI20, released to the global market at the end of 2015, is the updated version of SI10 PV pumping inverter. Comparing with SI10, the SI20 series are of enhanced working performance such as in stability, efficiency and other functions. Since the announcement, SI20 has gained more than 1000 successful application examples in various fields like agricultural irrigation, desertification control, stock farming, solar energy powered fountains and so forth. Below are the main features of SI20:

photovoltaic pump system

1. Convert DC to AC power

SI20 can convert the direct current generated by solar panels into alternating current to drive photovoltaic pumps.

2. Adjustable output frequency

It is capable of adjusting the output frequency automatically in line with the irradiation intensity.

3. Maximum Power Point Tracking function

Built-in with the MPPT (maximum power point tracking) function, so the photovoltaic pumping system can produce better power outputs to improve the working efficiency of pumps.

4. Store water, instead of storing power

The energy storing devices such as battery have been eliminated from the system, so all the AC power can be directly used to drive pumps with the lowest energy loss.

5. Asynchronous and synchronous motors are available

While our SI10 can only work with asynchronous 3 phase induction motors, the SI20 series can work perfectly with both asynchronous and synchronous 3 phase induction motors.

6. Support various kinds of pumps

Both the surface mount and submersible pumps are compatible with the photovoltaic pumping system.

7. Remote monitor function

SI20 has inbuilt S200-GPRS that users can monitor the whole photovoltaic pumping system online at home or other place via our PC remote monitoring system. On the basis of user-defined curve, SI20 can automatically calculate the present flow speed, flow per day, present power, total generation and more status parameters of the solar pumping system.

8. USB data recorder

As SI20 has developed with the USB data recorder, so users can duplicate the data excel to monitor the PV pumping system offline at any time.

9. Complete protections

SI20 has designed with a wide range of protection functions such as water fulfill, dry run, low frequency, high voltage, short circuit, over heat, phase missing and more.

10. User-friendly

SI20 is designed with an intuitive operation panel along with detailed instructions, so it is convenient in installation, operation and maintenance. Additionally, the cooling and shielding effect is great.

Besides, Veichi Electric also provides other solar energy products such as PV inverter at wholesale price.
