What is solar pump controller? How does solar pump controller work?

Solar pump controller also named solar pump inverter, solar pump drive, solar water pump controller, or solar water pump inverter, it is one of the key components in the solar pumping system. The function of the solar pump controller for the solar pumping system is like a “heart” for humans.

Solar pump controller can run water pump with solar. When there is enough sunshine, it can convert DC from solar panels to AC to drive the water pump to get the water, from water sources to the places where need water.

It is built based on MPPT Maximum Power Point Tracking (MPPT) technology, which can maximize the output efficiency of solar panels, and make full use of solar energy to create AC electricity.

What features does solar pump controller have?

  • No need batteries or other power staters, it is cost effective choice in long term
  • It can work in a lowest cost way both in day time and dark time
  • Solar pump inverter is durable and reliable for end users, can be widely accepted by many markets and clients

  • It needs much less cost compare with traditional diesel generator pump system
  • Friendly to environment with zero emission of greenhouse gases
  • No need for human to maintain, it can automatically start to run when there is sunshine, and stop to run when there is no sunshine, or when sunshine is weak

What is solar pumping system? How does solar pumping system work?

Solar pumping systems mainly consists of solar panels, solar pump controller, solar water pump and cables.

The function of solar pump system is when sunshine is strong enough, this system can get energy from the sunshine by solar panels, then it drives the pump to get the water from the water sources (like well, river, and so on).

Solar pumping systems can be widely used in many different areas, like drinking water for humans or animals, agricultural irrigation, desert control, forestry irrigation, pond management, and industrial use such as wastewater treatment, etc.

Solar pump system is friendly to the environment and human, it also has good ROI (Return On Investment), widely accepted by worldwide markets.

What kinds of solar pump controllers there are in the most of worldwide market?

There are two main kinds solar pump inverters.

The first one is solar dc pump inverter, it is used with dc pump. It is mainly for small power of solar pump, most are less than 0.75kw.

The second one is solar ac pump inverter, it is used with ac pump, including surfaced pump and submersible pump, mainly for large pumps which power is over 1.5kw. The popular power of solar ac pump inverters in the market are from 2.2 to 110kw.

By the way, both the surface pump and submersible pump can work with solar pump controller.

What kind of solar pump controller is more popular in most markets? Solar DC pump controller or solar ac pump controller?

Compare with solar dc pump system and solar ac pump system, the solar ac pump system has larger demand in most the markets, because it is more stable and have a longer lifetime. What’s more, solar ac pump system can be used in more different situations, especially for larger projects which need more water flower.

Which kind of solar pump controller is better? Solar ac pump inverter or solar dc pump inverter is better?

It depends on your project demands, if your need a small water flower at a certain time, especially if the pump power in your solar pumping system is less than 0.75kw, then solar dc pump inverter is more suitable for you. Because it can help you reduce less cost. But if your need more water and need to use large power pump in your project, then solar ac pump inverter and solar ac pump system is the better choice for you.

Can I use solar ac pump inverter to connect and work with solar dc pump?

No, solar ac pump inverter can only work with solar ac pump, solar dc pump inverter can only work with solar dc pump.

Besides, the specification of output from inverter should be same as input of pump. For example, three phase 380vac output solar ac pump inverter, only can work with three phase 380vac input solar ac pump.

What kinds of solar ac pump inverter are popular in most markets?

There are mainly three types of solar ac pump inverters in most markets, they are:

  • Solar pump inverter with single phase 220-240vac output
  • Solar pump inverter with three phase 220-240vac output
  • Solar pump inverter with three phase 380-460vac output

What is single phase solar pump controller?

Normally, when we call single phase solar pump controller, it is with single phase,220vac output, it can be used for single phase pump, which need single phase 220vac input.

What is 3 phase solar pump controller?

Normally, when we mention 3 phase solar pump controllers, they consist of two types of 3 phase solar pump controllers. One is 3 phase 220vac output, the other is 3 phase 380vac output.

These 2 different types of 3 phase solar pump controllers have to work with different types of ac input solar pumps, 3 phases, 220vac output solar pump controller must work with 3 phase 220vac input pump, 3 phase 380/460vac solar pump controller must work with 3 phase 380/460vac input pump.

Most of large solar pump system request using 3 phase 380vac output solar pump controllers in the word to get large water flower from the solar pumps.

Whether solar pump controller only can work with solar energy? Can it work with AC grid power? Or generator?

Take VOKEK VOK200 Series Solar pump controller as an example, it can work with AC grid (single phase 220vac input/ three phase 220vac input/ three phase 380vac or 460vac input), Generator, and solar arrays.

When sunshine is strong enough, it works with solar panels only. When sunshine is not strong enough, it can get power from AC grid or generator.

Besides, it also has hybrid function, when the sunshine is not strong enough (there still having sunshine), it can connect with both solar arrays and AC grid power at the same time, and get the power from AC grid power and solar arrays at the same time. Very convenient for end-users and save cost intelligently.

How can I make solar pump system perform well? What affects the performance of solar pump system?

Solar pump system consists of solar panels, solar pump, solar pump inverter solar cables, relative switches, solar bracket.

For most solar pump system project cases, the performance of solar pump system many related with the following three aspects:

  • The quality of solar panels
  • The quality of pump
  • The quality and adjustment (or installation skill) of solar pumping inverter
  • Whether the cable type and quality are good and suitable for your solar pump system

How many solar panels does it take to power a water pump? How many solar panels do I need to run a water pump?

Different brands of solar pump controllers have different answers to this question. Normally, If you are using VOKEK solar water pumping controller, we suggest the input of total power from the solar panels should be total power of solar arrays input should be large than 1.3 to 1.5 times of rated power of pumps, and the rated power of inverter should be same or larger than the rated power of pumps.

What is a good solar water pumping controller?

A good solar water pumping controller has to be high quality with good long term stable and high-efficiency performance.

What’s more, this kind of product need to do some setting during installation, and it has 12/18 months warranty normally, you’d better buy from reliable solar water pumping controller supplier.
