How To Use Solar Charge Controller

Hello Friends and welcome to my Blog. In this blog, you will learn how to install a solar charge controller in a few mints.
Let’s gets started

What is a Solar Charge Controller?

        Guys solar charge controller is a device that is basically used for controlling or regulating voltage and current that comes from solar “PV” panels to the battery. Actually, the solar charge controller protects batteries from overcharging.
Most of the 12-volt solar panel output voltage is about 16 to 20 volts. If you give these high voltages direct to 12 volts battery your battery will be damaged from overcharging. Most of the Batteries need around 14 to 14.5 v to get fully charged.

A little bit about the solar charge controller that I am using:

The controller that I am using is CM3024Z. This charge controller comes in different amperes rating like 10A,20A,30A, etc. The one that I am using is 30A .it’s easily available in the market and also cheap in a prize.
To connect the solar charge controller to your setup is very easy.

Battery connection:

As you can see on the front side of the device six holes with a screw on it.
The middle two holes are for the battery connection. Connect the battery positive terminal to the positive point on the charge controller and negative terminal of the battery to the negative point on the controller. Both the positive and negative signs are shown on the controller, while in battery red is positive and black is negative. when you connect the 12 volts battery to the charge controller the device will be turned on and you will see some data on the display.

Solar panel connection:

Now connect the solar panel to the charge controller .same as you connect the battery. Two holes on the left side of the solar charge controller are for the solar panel you will see a solar sign on it.
Connect the solar panel positive wire to the positive point on the charge controller and negative wire to the negative point on the charge controller.
After a successful connection, you will see an arrow blinking on the display from panels towards the battery. Arrow blinking represents power.
Load Connection:
The left side two holes on the charge controller are for the load connection. From here you can give direct 12 volts DC to your load or give it to an inverter as input. For AC power.
An arrow blinking will be shown on the screen it means that a load is connected to the solar charge controller.
Now your controller is successfully installed in your solar setup.
Menu Button:
Use menu buttons for showing different data and controlling the input and output power.
From the menu button, you can control power on and off.
+ AND-: button is used for increment and decrements the different values.
Temperature Sensor:
Temperature sensor are use to show temperature 
Without casing the circuit looks like this:
