It is possible to run the pump directly off of a battery bank. You will need to make sure that the voltage of the battery bank falls within the input range of the controller.

The Solar pumps we use work on low voltage so extending the cable too far will affect the performance and thicker cables need to be used to counter the volt drop.We would not recommend extending the cable more than 100-120m depending on the size and voltage of the pump. It's best to increase the cable between the controller and pump and keep the cables between the controller and panels as short as...

The motors that we use are AC low voltage motors which means that they do not work with brushes at all. The only wearable parts on the motors are the bearings and mechanical seals like normal AC motors.

The controller does not have the input for mains or generator power but the pump can be powered by means of a DC power supply that can supply the controller the correct voltage and amperage for the pump to operate efficiently.

You can increase the power to the controller, however, you will need to make sure that the voltage input to the controller remains within the limits. The additional power will not increase the peak flow rate; however, the additional power will allow the pump to run more efficiently during the early mornings, late afternoons as well as during cloudy days.

You do not need to add batteries in order for this pump to work, however, the 3rd gen controllers have the battery function built in so adding batteries at a later stage is also possible.

Head is the maximum vertical height above the pump that the water needs to be pushed and this also includes the losses over the distance that needs to be pumped.

Solar pump is as the new technology product powered by solar energy

A solar water pump is used for extracting water from ponds, rivers, borewells or other sources of water which are then used to meet the water requirements for irrigation, community water supply, livestock and other purposes.

Solar pumps operate on solar energy available free with nature, and thus save expenditure on diesel or electricity.The cost of operation and maintenance of solar pumps is negligibleUseful for water pumping in remote areas without grid power.

The different types of pumps are :(a) D.C. surface centrifugal pumpset(b) D.C. submersible pumpset(c) D.C. swimming pool pumpset(d) A.C. submersible pumpset

We have patent for our DC permanent magnet synchronous motor. Besides, we will use the best material for the spare parts. 1. 304 stainless steel impeller and pump body 2. 321 stainless steel shaft 3. NSK bearing 4. Alloy mechanical seal 5.MPPT controller

First, we are so sorry that we have no plan to attend this April caton fair. Our factory is located in daxi town wenling city, a bit far from Guanzhou. If you take raliway will cost about 8 hours, by flight to taizhou, and we can come to pick you up. It will be about 2 hours

At the moment we have no plan to attend the exhibition and fair in April.

Except for the brushless solar pump, our electrical submersible well pumps and surface domestic water pumps can be customized

all the times, we can do QB series solar pump, but our type is with stainless steel pump body. The price is a bit high, in April, our company turn to making cast iron pump body type, the price will be much more competitive

With more than 1 years' research and development, our company have our own screw solar pump. From April 2017, our factory will comprehensively make these model, meanwhile i will update the product list on my website as soon as possible

Firstly, your first order should be at least 100PCS, then your should create at least 30,0000USD per year from us

Sure, to carter to the peak sales season, if your order of DC solar pump reaches 20PCS we will give discount, and if you would pay to our alibaba account in March, we will give extra 5% discount

Kindly to know our DC solar pump with permanent magnet synchronous motor is our patented product, that's why our price is more competitive than other factories. Besides, our 2 inch small DC solar pump with mini design is unique of our company. Most other factories exported with their own brand, but we can do OEM for our clients.

our solar pump can be divided into two kinds, one is with induction brush motor, the other is with permanent magnet synchronous brushless motor. The DC former type is with cheap price and can be operated by solar panel directly. All the material for the latter is the best with best quality and MPPT controller and can be operated by solar panel directly. The AC solar pump should be operated by sola...

Certainly, if you need our technical direction, we can offer the the relative video for your reference, also we can offer the connection drawing

We are absolute manufacturer specialized in kinds of water pumps and featured by solar pumps

Absolutely, we can do OEM for you and use your brand, but the MOQ for the pump should be more than 50 PSC

Certainly,we could pack your goods in pallets. Since it’s not of standard package, it will involve some extra cost

our submersible well pump is the regular submersible pump which is very popular in Middle east and south east area. Good quality with cheap price, above all, our submersible well pump can be customized. even we can offer sample for testing

Our DC solar pump is permanent magnet synchronous motor, which we have patent. 304 stainless steel impeller, 304 stainless steel pump body. 321 stainless steel motor shaft, NSK bearing. From this new year on, our cable was cut to 3 meter because of the growth of cooper price. MPPT controller can take the advantage of solar power more efficiently. 3year warranty

3 years for brushless solar pump and 1 year for brush deep well submersible pump

after you received the pump, we will send you the installation video for you

Tax refund is a policy in China toencourage exportation. The policy is only subject to normal exporting businesses, following strictly all exporting procedures. In our operation, we will cut off the taxcosts in unit prices and then get the refund from our government when goods are exported. In cash transactions, the policy doesn’t apply.
