Solar charging 12v battery

Though it is easy to charge solar panel 12v battery, it can troubleshoot. Sometimes it is an ordinary and common matter that you can face solar charging 12v battery problem. Behind this problem, there are some particular causes. If you properly know them, you can solve this complication without taking anyone’s help.

Solar battery charging problems

To find out the charging problem, you need to check the battery, regulator, power-supply, charging source, etc. For this, you need the tools below:

  • A digital multimeter
  • A small screwdriver
  • Wire strippers (one pair)

You need the multimeter to check the DC voltage. However, do the tests below to find out the charging problem.

1. Test data logger

Take the multimeter. Then set is to the 20Vdc range. Use the red probe in a socket (mAVΩ) and connect the black probe in the socket (COM). Then you should touch the end of the red probe to the red wire’s bare end. And touch the black probe to the black wire or the terminal screw that labeled G.

2. Ensure the power supply is turned on

Check the power supply and ensure that it is turned on. You may be surprised that it is very common for a user to turn off the power supply to the data logger. It is caused by various reasons. But later, the users forget to turn it on. If you see that the power switch is off, you should make it on. Then repeat the above step. But if you find that the power switch is on, then you need to follow the step below.

3. Measure the power supply voltage

When you look at the power supply, you may notice the terminals named 12V and G. You need to pick one terminal to use it. Now you need to measure 12v and ground terminals voltage on the power supply. If you get more than 11 volts on the regulator and less than it on the data logger, you need to check the connector wires. If you get the connector wire loose, you should reconnect it. Before doing it, you should turn the power off. But if you see the connection is well, you need to follow the step below.

4. Check the battery voltage

Now you have to test the voltage of your battery. For this, you need to connect the black probe to the negative terminal and then the red one to the positive terminal. If you see that the voltage is more than 11v, your battery is then okay. But you need to repair the power supply. If you see that the battery voltage is less than 11v, then you need to disconnect the battery.

5. After disconnecting the battery check the power supply voltage

Disconnect your battery. Then recheck the power supply voltage. For this, follow step 3. If you see the voltage is 13-14v, you need to change the battery. Now, you need to check the voltage of the two terminals of power supply. You can do it with any color probe. The terminals are labeled CHG. If you see the voltage reading of the terminal is 17v, you need to repair the power supply.

6. Solar panel voltage measurement

Now disconnect the power supply from the solar panel. It is easy to take the reading of the panel’s voltage with the probes by touching than to the bar wires end of the solar panel. You should do this test at day time when your solar panel is under the sunlight. Connect the red probe to the red wire and black one to the black wire and measure the voltage. If you find that the voltage of the panel is less than 17 volt under the full sunlight, you need to replace the solar panel.

7. The current test of solar panel

It is the last step. You need to use the DMM to measure the current that comes from your solar panel. You should take care of sparking. For this, cover the panel with a cloth while testing the amps. To measure current, you should set the red lead of the DMM to 10ADC socket and then range it to 10A. Now touch the red probe to the red point of the panel and black probe to the black or negative lead of the panel. After connecting the probes, remove the cloth covered the solar panel and let the panel to expose sunlight. The output of the current solar panels differs for sizes. For a 10W panel, the maximum output is 0.7A, for 10 W the output is 1.4A, for 50W the output is 3.3A, and for 90W the output is 5.6A. But this measurement can be lower than the maximum rage because of the amount of light. But this amount needs to be close to the value that is proper for the solar panel size. When your solar panel gets good sunlight, the measurement from the panel is close to its output current. If you see that the current measurement is not realistic, think that your solar panel or the connector wires have been damaged.

So, to find the problem why the battery of your solar panel is not charging, you should do the steps and check every part of the system and the power source.

Charging the 12v battery with solar panel

Now it is time to know how to use a solar panel to charge the 12v battery. It is easy to charge the battery of a solar panel. Just you need some equipment to make the process safe, straightforward, and affordable.

For this, you need some items such as battery, charger, charger controller, converter, solar panel, etc. You will get them at any hardware or online shop. There are many brands of these items within various price ranges. You can mount a 12v solar panel with battery in the yard or on your car or boat or near your camping tent. You should install it under direct sunlight. However, let’s see what items you need to charge a 12v battery.

1. Solar Panel

You need a solar panel. You should take one that offers you a lot of features and enough power under your budget. Choose a flexible, lightweight one that is easy to take from here to there. But it does not mean that you take a sheer panel that is not stable or has no quality. Your solar panel needs to be rugged enough to produce enough power in low light condition. It is better to choose a portable one than a fixed solar panel. For a vehicle, portable panels are the best. But in the compact panel, the capacity of power and durability is lower. But they are cheap and easy to use.

12V solar panels are less expensive and provide better performance. Besides, the customized solar panel is also a good choice.

2. Charge Controller

Most of the solar panels the portable panels have a charge controller. If your solar panel does not have a charge controller, you need to buy one. It is necessary to the protection of the panel and increases the performance. This tool disconnects the battery from the panel when it gets a full charge.

3. Battery

The size and power of the batteries are of many. But here, we are talking about 12v batteries. However, this battery is useful and can use it for various purposes. You can use it to charge your phone or use it on your car or boat.

4. Inverter

The DC voltage of a battery is 12. But most of the household devices need 120 AC volts to run. If you have an inverter such as cigarette lighter of car, the stored battery power can be used to charge some household gadgets. You should remind that the current of the inverter needs to be accurate flow.

5. Solar tracker

If you use a solar tracker, it helps to get the maximum power of a solar panel. We know that it is not possible to get 100% sunlight in some place such as mountain, jungle or the shaded area. A solar tracker helps you to increase the solar panel effectiveness.

How to use a solar panel to charge a battery

Now I am describing how to use a solar panel to charge the battery in brief.

  • Check how much power your solar panel will produce. For this, see the back side sticker. Here you will see the wattage. If you do not see it, you need to measure it by yourself. You will find two types of controllers, such as MPPT and PWM. It is better to take an MPPT charge controller.
  • Now mount the solar panel at right place. Connect the controller. Before it, mount the controller in a place where water and others cannot hamper it. Connect the red and black wires to the panel. Then connect the cables to the battery.
  • After that, connect the input wires to charge connector. It is better to use MC4 connector. Then check the output of the connector to be sure that it is working.
  • Now connect the battery to the battery connector and leave it until it gets fully charged.
