Solar pumping system Overview
Solar pumping system is a water pumping system running on electricity generated by PV modules or backup by grid electricity. It is a stand-alone system without battery bank. The operation of solar powered pumps enjoys lower operation and maintenance costs and has less environmental impact when comparing with pumps powered by others. The key of the pumping system is pumping inverter, which had combiner function of MPPT controller, three phase inverter and AC driver(VFD), thus we'd like to call it solar VFD.
A solar pumping system is mainly composed of three parts: solar panels/the controller (or pumping inverter)/pump.
Some small pump is dived by DC power directly after modify, people call them DC pump.
Applications of solar pumping system: Such as garden fountains, landscaping, drinking water for livestock, or irrigation projects.

Detail of solar pump inverter
The key of the system is solar pumping inverter. Ours combined MPPT/VFD/three phase inverter function. It drives max. self same power three phase pump.
Solar pumping inverter also called solar VFD, which is the key of the solar pumping system. It combined MPPT controller/inverter/ VFD function, and the system with it can be battery-less. Solar pumping systems are suitable for applications such as garden fountains, landscaping, drinking water for livestock, or small irrigation projects.
Features of Solar pump inverter

FAQ
1. Q: Must buy the whole system? And which type pump is suitable for the system.
A: You can just choose inverter from us, but the whole system should make sure all parts in good quality. Frankly pump is not our strong point, you may have pump yet or purchase it in local store, of course we can find for you too. Various pumps are available for our inverter.
2. Q: What's your strengths ?
A:The power ratio of panel: inverter: pump, our min. can be 1.5:1:1, our competitor ask 2:1.5:1 at least. That is your pump is 1KW, thus you can set our 1KW inverter and 1.5KW panel. But should make sure the input voltage of inverter should in the range required.
In other word, our system is really high cost performance.
3. Q:What's the benefits of the system?
A:1st You no need pay electric charge, all power from solar. 2nd the system is green and environmental, we will help in the working of protect our beautiful home.
4. Q:Is it easy install?
A:Yes, you can find a electrician to install the whole system. From panel to inverter, we just need fixed them and connect them together.
5. Q:About the transportation
A: We recommend sea shipping due to panels are heavy and big size usually. But if you just purchase inverter from us and others buy from local market, thus can consider the express. Usually our smaller power inverter is compact.
6. Q:About the warranty
A:The warranty of inverter is 2 years, and the life span is 10-15 years;
For panels, we can guarantee 5 years with 100% performance guarantee, 10 years 90% rated power output,25 years 80% rated power output. Of course you should choose our good quality one which recommened.
Bracket is 1 year, we recommend C type steel one usually.
All parts we will choose good quality for you to make sure the whole system can used in long time and wish you can introduce us to your friends/ neighbors/ neighbor. We devote ourselves to solar system and looking for long business relation with you always.
