The NOVA YJSS 20A charging generator is the very heart and brain of your solar system for boats, cars, caravans and motorhomes! According to the manufacturer, it is the most cost-effective regulator on the market. The fact that it is small and flexible and with lots of smart control functions doesn't make matters worse, does it? Despite its size, it has loads of features such as

1-Wide compatibility: The solar charger controller is automatically compatible with 12V or 24V systems, suitable for lead acid batteries. Dual USB 5V output ports support mobile phones, tablets or other devices that require 5V voltage.

2-Reliable protection: Solar charge controller provides overcurrent protection, short circuit protection, reverse connection protection, low voltage and overcharge protection, a reliable protection for your devices.

3-Intelligent controller: Built-in industrial microcontroller for automatic management and memorization of various parameters set by the user so that data will not be lost when the battery runs out.

4-Digital LCD screen: Intuitive LCD screen that can clearly indicate status and data, you can easily change modes and aprameter configuration, suitable for home, industry, commercial, etc.

5-Easy to use: The charge controller should connect the battery first, then the solar panel and finally the load! You can easily change the settings with a simple button press.

This is how it works

A charge controller like this limits the rate at which electrical current is added to or withdrawn from the battery. It prevents overcharging and can prevent against overvoltage. Overvoltage can reduce battery performance and life.
