Allto Solar 20A MPPT Charger with Backlit LCD and Temp Sensor for 12/24V Batteries

Advanced MPPT Technology

The innovative Max Power Point Tracking (MPPT) algorithm ensures high tracking efficiency of up to 99% and peak conversion efficiency of 98%. This highly efficient technology improves the utilization rate of your solar panel system by approximately 20%-30% compared to traditional Pulse Width Modulation (PWM) controllers. In cloudy conditions, this standout feature guarantees maximized solar panel production, optimizing your energy output even when the sun is not at its brightest.

Comprehensive System Protections

With built-in multiple protections, including PV over-voltage, battery over-voltage, over-temperature, over-charging, short-circuit, reverse polarity, and temperature compensation, this solar charge controller is designed to safeguard your battery. It ensures that your battery is rapidly and efficiently charged to 100%, providing reliable and long-lasting performance.

Safe and Efficient Charging

The adaptive 3-stages charging algorithm (Bulk, Absorption, Float) enables quick and safe battery charging. This ensures that your battery is securely recharged, extending its life and enhancing the overall performance of your system. Whether you are charging deep cycle sealed, AGM, gel, flooded, sealed, lead-acid, or LiFePO4 lithium batteries, this versatile controller is a reliable choice.

Compatible with Multiple Battery Types

Our solar charge controller is compatible with a wide range of battery types, including 12V and 24V deep cycle sealed (AGM), gel, flooded, sealed, lead-acid, and LiFePO4 lithium batteries. With 6 LED indicators, you can easily select the right battery type among 12V, 12V AGM, 12V lithium, 24V, 24V AGM, and 24V lithium. This makes it a versatile and user-friendly solution for various solar panel systems.

Real-time Monitoring

Featuring an RS232 port, this controller is compatible with a remote LCD monitor (sold separately) for real-time monitoring of your solar panel and battery performance. It provides multiple data points, displaying historical data for up to 60 days. Its compact design ensures easy installation, making it a perfect fit for virtually any installation location.
