Make sure the pump and controller are not touching each other.
Connect solar panel to dc pump.
Then exchange two wires of solar panel to the correct wiring.
A solar panel will vary the energy causing your pump to run erratically and possibly not at all.
There are dc solar pumps designed to work directly with a solar panel.
Whirlpool forums addict reference.
The voltage regulator came from e bay and is designed for golf cart use.
It depends on the pump.
If the wiring is incorrect the pump will run backwards.
An lcb decreases the voltage and increases the current output helping to handle the high current surge a pump needs to get started.
This connection involves three main steps.
You need a dc pump and pumps all require a certain amount of constant power to run.
Try wiring the panel to charge a battery and run the pump off the battery.
Most of common dc water pumps can work directly connected to the solar panel but their biggest problem is stuck.
Wire the solar pump and solar panels to the dc controller as per the wiring diagram.
The size and power needs of the motors used will dictate how many panels are needed.
However when it comes to using solar for motor operation having more power than is actually needed is recommended especially.
Install solar water pump 12v solar pump with 150 watt solar panel with borewell drill complete steps for more information please visit our website http www.
In a sale i picked up a 115w panel with 37v output and plan to connect this to a 12v dc 50w pump via a voltage regulator.
At dawn the sunlight begins to change from weak to strong when the output voltage of solar panel achieves the starting voltage the pump will start to work.
An even better solution is to also use a linear current booster lcb between the solar panel and the solar pump.

I am looking at a similar challenge a very simple solar powered pump that only operates when the sun is shining.
How to connect solar panel to a battery.
We therefore aim to have alternating current ac as this is more powerful and is what most appliances run on.
To get this set up we need to understand that the solar panels usually output direct current dc as earlier mentioned.
Using solar panels for dc motor operation is an environmentally friendly application that reduces the emission of greenhouse gases.
