battery charge controller which will control the receiving of electrical energy from the solar panel and supplying the direct current to the system stored in the battery Including supplying electricity directly to electrical appliances.

Wiring from the solar panel into the charging controller by connecting the cable to the correct polarity The red wire goes to the positive (+) terminal and the black wire goes to the negative (-) terminal.
Connect the wires from the battery charge controller. To the battery ball, by the battery, we will choose to use a 12V 12AH dry battery, which will have positive (+) and negative (-) terminals. Also make sure that the wires connecting all the terminals are tight enough. to prevent sparking which is the cause of the accumulation of heat energy
The wires that extend from the charge controller. at the battery terminal connection point We will use clamps to clamp the battery terminals. Which by the nature of the device is suitable for use together
When connecting the extension cord from the charge controller to the battery We will notice a light on the charging controller panel. in the battery point A light will flash to indicate that direct current (DC) power is now flowing into the system. which if the solar panel receives energy from the sun when The controller will receive electricity from the solar panel immediately. by letting us observe the light at PV
Now that our solar cell system is ready, the next step is to use the solar panel to receive energy directly from the sun.
This set of pumps will use DC power, which can use electricity from solar panels directly. and can be powered by batteries By using it, the pump must be immersed in water. and connect the hose or hose to the fountain making equipment
There are 2 power cords of the machine, the red is the positive (+) wire and the black wire is the negative (-) wire. This device is designed to be waterproof. Because the pump and part of the wire must be immersed in the water itself.
Then connect the switch to cut the circuit. By connecting the switch to the red line that will be connected to the positive (+) terminal of the charge controller, connect the wires to the charge controller which can work on either PV or battery power.
generally The switch to turn off and turn on the pump is also under water. which will be the foot switch Users will be able to use the foot pedal to open and close conveniently. But we use a normal on-off switch to modify it. without the need for the switch to be in or near water at all
When the solar panel is placed in the sunlight We’ll notice on the dashboard of the charge controller that the PV light is on instead of the battery, indicating that the solar panel can accept solar energy to produce direct current (DC).
We will begin to test the operation of the pump from the basin. by connecting the hose to the pump body Try submerging the pump into the water. Prepare for a test run by turning on the pump switch
The pump can be operated directly from solar panel power. and when the sun is gone The charge controller will immediately supply power from the battery. Therefore, even if the fountain is open all the time It’s not a waste of electricity in any way.
Fountains are usually outdoors. Which equipment can be immersed in water or wet is the pump body and some wires Therefore, we need to use a type of switch that is waterproof. or may use a waterproof floating box Installed in a place suitable for use in the installation of the switch. to prevent some time when it rains
When using the fountain pump for a long time There may be dirt that clogs the pump that is easily immersed in water. Therefore, we must bring a fine mesh to wrap the pump. To prevent dust, moss, water or other debris. can get clogged in the pump And in addition, we must keep cleaning the filter mesh as well.
Benefits received from the project
The fountain that flows in a stream looks cool to the eye. We can turn on the fountain all day and night without the need for power from other sources except the solar power pack. During the day, it uses electricity from solar panels directly. When the sun is gone, it returns to use the energy in the battery as before. and recharging the battery to the built-in These are examples of complementary energy use. And there is no expiration date.
