Solar Charge Controller

Solar charge controllers make your solar batteries work more efficiently and they can protect your batteries from overcharging or discharging. In this collection, we have collected a wide range of top-quality solar charge controllers for you to choose from. Including MPPT controllers, PWM solar controllers, EPever solar controllers, and other controllers. MPPT and PWM controllers are the most popular ones. Of course, if you want to know more about them, please view them as follows.

Solar charge controllers combined the panels with the batteries, that is to say, there are various kinds of solar charge controllers are available online. Before you are going to buy a solar charge controller, you have to know which system you need, 12, 24, 48-volt or 110-volt/220-volt AC systems. In addition, you need to know the batteries situation in your system. Last, you need to notice what kind of blocking diodes are inside your solar charge controllers. In general, MPPT model solar charge controller is more expensive than other models, so it is not a small investment for you if you are going to buy it. Anyway, you need to know the amps, watts, volts for your solar array and batteries before you buy. You need to know what types of device do you need to charge, whether off-the-grid system or an RV.

MPPT controller allows for up to thirty percent more power than the PWM controller and can be applied for higher voltages. The MPPT controllers are capable of handling inclement weather as they will preserve the battery output and compensate for low power. A PWM controller is a switch that connects a solar array to a battery. PWM charge controllers are an older technology and are cheaper, but less efficient than MPPT charge controllers. Both are widely used, have similar lifespans, and preserve the life of your batteries.


What Is a Solar Charge Controller?

The solar charge controller is used in the solar power system to control the multi-channel solar cell array to charge the battery. In order to protect the battery and prevent overcharging, the solar charge controller is included in most solar power generation systems. The basic function is to cut off the charging current when the battery is full. Of course, when choosing to buy a solar charge controller, due to the different charging characteristics of the battery, you have to look at the charging characteristics of the battery to buy different models or different sizes of solar charge controllers.

What Type of Solar Charge Controller Is There?

The best solar charge controller has two main models: MPPT Solar Charge Controller and PWM Solar Charge Controller.

How to Choose the Solar Charge Controller?

The size of the solar charge controller depends on the current of the solar cell array and the voltage of the solar system. When choosing to buy a solar charge controller, you need to know what type of system it will be used with, such as a 12, 24, 48 V, or 110 V/220 V AC system. Of course, you also need to know how many batteries your system has in total and their ampere-hour capacity.

To give an example: If your solar system has a voltage of 24 volts and your amperage is 14 amps, you need a solar charge controller with at least 14 amps. However, due to environmental factors, you need to consider an additional 25%. This brings the minimum ampere that the solar charger controller must have to 17.5 amperes. In this example, you need a 24V, 20A charge controller.

How Does the Solar Charge Controller Work?

The solar charge controller regulates the power transferred from the solar panel to the battery. The use of a charge controller is important because it can increase the efficiency of the solar system by up to 50%, prevent overcharging of the battery, and extend the life of the battery when used correctly. If there is no regulation, the battery is easily damaged, which will cost you money and time to repair.

Main Features of Solar Charge Controller:

  • High reliability;
  • According to the charge level of the battery, protect the battery from overcharging;
  • Reverse current protection to prevent solar panels from draining battery power at night;
  • Reduce system maintenance and extend battery life;
  • Disconnect the connected load when the battery is low, and turn it back on when the battery is charging;
  • Can display battery pack voltage, charging status, solar panel current;
