Dyness 40A MPPT Solar Charge Controller (Model ARM24V-40A) Instruction Manual

1. Másview e Introducción

The Dyness 40A MPPT Solar Charge Controller is designed to efficiently manage power flow from your solar panels to your battery system. It features advanced Maximum Power Point Tracking (MPPT) technology to maximize energy harvest and comprehensive protection features for system safety.

Advanced Tracking Technology

This controller utilizes advanced MPPT technology, boasting a high tracking efficiency of up to 99% and a peak conversion efficiency of 98%. It continuously tracks the solar array's maximum power point to ensure the maximum amount of power is delivered to charge the battery, even in variable light conditions such as cloudy environments.

Powerful All-Around Protection

The Dyness MPPT Controller integrates a full suite of battery protection features, including: Over-charge/discharge, PV over-voltage, short-circuit, and overheating protections. These safeguards ensure worry-free and secure charging. Internal cushioning material is incorporated to minimize damage to the controller from vibrations, making it suitable for mobile applications like caravans.

12V/24V Auto-Recognition

The controller automatically recognizes 12V/24V DC voltage systems. For Lithium batteries, manual parameterization is required. It supports various battery types, including AGM, GEL, Flooded, and Lithium batteries.
