The SUAOKI 20A solar charge controller is perfect for people who want to take advantage of solar energy to power up devices when off-grid. It regulates the amount of solar power going into your device's battery from the solar panel. It makes sure that during the day, your batteries are nor overcharged. At night, it ensures that the power doesn't drain from the batteries to go backward to the solar panel. All in all, it manages the flux of power between the solar panel and the batteries safely protecting your devices thanks to the under voltage protection, overload short circuit protection, reverse polarity protection, and over charge protection. 

It uses PWM technology. PWM stands for Pulse Width Modulation. This type of solar charge controller operates by making a direct connection from the solar panel to the battery bank. The result of this PWM solar charge controller is that the voltage of the array will be pulled down to the one of the battery, prolonging the battery life. This solar charge controller can be used to power up small electronic devices via the 2 USB ports, including Smartphones, tablets, GPS navigators, laptops, as well as other devices using the other exposed terminals perfect for lamps, fans, portable fridges and coolers, and more. 

This solar charge controller is very easy to install and very intuitive. It features a sophisticated and easy-to-read an LCD screen that displays all parameters of the controller including system information, error codes and more. The SUAOKI 20A solar charge controller also has two red buttons allow you to turn on and off the delivery of energy from the solar panel to the battery and to your electronic devices. It is important to note that the solar charge controller has to detect the battery type (either 12V or 24V) before the installation. Moreover, it will work with photovoltaic solar panels only.
