When you are installing a solar energy system, you will realize that apart from the main components of the solar energy system, you will need to do a lot of research on the other parts of the solar energy system. One of the very important components of a solar system is the MPPT solar charge controller. If you want to build a solar system with solar battery, you need to have a MPPT solar charge controller which not only optimizes the charging and discharging of the solar battery, but also improves the efficiency of the solar system. In this article, we will introduce you the size of the MPPT solar charge controller you need for your solar system and the related are issues.

1. How to choose the right MPPT solar charge controller?

The main purpose of the MPPT solar charge controller is to ensure that the solar battery maintains maximum output efficiency by adjusting the operating point of the solar battery in real time. This process involves tracking the output voltage and current of the solar battery as well as the power of the solar panels in order to adapt to changing light and other factors. So when we choose MPPT solar charge controller, we usually need to select mppt solar charge controller by the data of the energy storage system and the solar panel so that the mppt solar charge controller can work at its best efficiency. Below we will specifically introduce you how to choose the right MPPT solar charge controller.

Voltage of the storage system:

For the voltage of the storage system, you can check the manual of the solar battery. Generally speaking, the manual of the solar battery will indicate the relevant information of the product, you can get the detailed output voltage of the solar battery according to the manual, if your manual is lost, you can also use a multimeter will voltmeter to test the voltage of the solar battery, connect it between the positive and negative poles of the solar battery directly, then you can test the voltage of the solar battery.

The total power of the solar panels:

Usually, the solar panels will be affixed with labels, these labels will be labelled with the wattage of each solar panel, the wattage of the solar panels in units of W. Then you can need the number of solar panels in the solar energy system,

the total power of the solar panels = the power of a single solar panel * the number of solar panels

After you know these two data, you can find out the rated charging current of the mppt solar charge controller in the table below according to these two data.

If the voltage of your energy storage system is 24V, and the total power of your solar panels is 1200W, then according to the table below, you will know that the rated charging current of mppt solar charge controller is 50A.

2. Considerations when choosing MPPT solar charge controller

Protection function: For MPPT solar charge controller, when you choose, ensure that the rated charging current meets the requirements of the solar energy system, which is only the most basic requirement. You also need to consider the over-voltage protection, under-voltage protection, over-current protection and a series of other protection functions of the mppt solar charge controller, in order to ensure the stable operation of the solar system.

Brand: For mppt solar charge controller, if you are in normal use, mppt solar charge controller generally will not cause too much damage, but a well-known brand of mppt solar charge controller can guarantee the quality of the product as well as the after-sales service, to bring you a better product. After-sales service, to bring you a better experience.

Price: This is one of the most important factors in choosing MPPTsolar charge controller. Generally speaking, the price of mppt solar charge controller is not too expensive, but you should not buy too cheap mppt solar charge controller, because the price is too low mppt solar charge controller may be refurbished mppt solar charge controller. This may not guarantee the performance and other aspects of the product. It is recommended that you choose a higher mppt solar charge controller within your budget.

Other features: For mppt solar charge controller, the solar energy system can work for a long time, so it is also required that the mppt solar charge controller should have enough stability, so you also need to consider the IP rating, pressure resistance rating, etc. of the mppt solar charge controller when choosing. So you also need to consider the IP rating of the mppt solar charge controller when choosing it, the anti-voltage rating and so on.

3. Is the MPPT solar charge controller worth using?

The main purpose of the mppt solar charge controller is to quickly charge the solar cells and optimize the charging process of the solar cells in order to ensure that the load receives maximum current support. With the mppt solar charge controller you also get a higher level of DC-DC converter technology. In solar systems where the mppt solar charge controller is installed the mppt solar charge controller regulates and monitors the output power of the solar panels in a fine-grained manner.

The MPPT solar charge controller regulates and monitors the power output of the solar panels in order to ensure that the solar arrays and the solar cells operate optimally. Moreover, the price of the mppt solar charge controller is one of the lower components in the overall solar system. In terms of features and price, the mppt solar charge controller is well worth installing.

Conclusion:

The MPPT solar charge controller is an important part of a solar energy storage system if you want to store solar power in solar batteries. So you will need to know how to choose the MPPT solar charge controller to ensure that the solar system can generate electricity efficiently. Then the relevant content we have mentioned above can help you.
