20 Amp Solar Charge Controller - 12/24 Volt Lithium Compatible

Experience upgraded performance with the revamped AIMS Power 20 Amp Solar Charge Controller. Built for durability, this controller handles strenuous, continuous use while offering simple, easy-to-use input and output terminals—perfect for on the go, DIY solar projects.

Designed for efficiency, this charge controller supports 240 watts of continuous charging on a 12V solar system and 480 watts on a 24V system, delivering up to 20 amps per hour to recharge your battery bank. By regulating the volatile energy from solar cells, it converts raw photovoltaic power into clean, stable DC energy for optimal battery charging.

Compact & Versatile

With a digital display for selectable amperage or voltage monitoring, this compact controller (just 6.5” x 3.65” x 1.25″) offers limitless mounting possibilities. Easily install it in vehicles, RVs, boats, cabins, or any confined space where reliable solar power is needed.

Advanced Protection Features

Equipped with solar overcurrent protection, this charge controller safely regulates voltage flow to prevent overcharging. It also includes reverse polarity protection, overload, short circuit, and high-temperature protection, ensuring long-term system reliability.

Sustainable Power Solution

Compatible with lithium, open lead-acid, sealed, and AGM batteries, this charge controller provides steady daytime charging without reliance on gas or diesel generators—an eco-friendly alternative for off-grid power needs.
