Solar charge controller MPPT Qoltec 53661 with temperature sensor 20A, 12V, 24V, LCD, 2 x USB, 2 year warranty

Intelligent Solar Energy Management

This Qoltec solar charge controller, with a current of 20A, is designed for efficient management of the battery charging process in photovoltaic systems. It utilizes MPPT (Maximum Power Point Tracking) technology, which maximizes the efficiency of solar panels and optimizes energy harvesting. The system constantly monitors and adjusts the voltage and current from the panels, ensuring maximum possible efficiency, even in variable weather conditions – with partial shading or changes in light intensity. This is an ideal solution for both home installations and portable systems, on boats or in campers.

Monitoring and Safety

A clear LCD display allows for real-time monitoring of key device operating parameters: charging status, load, voltage and current. A built-in temperature sensor ensures battery safety by adjusting charging parameters to its current temperature. The controller is equipped with a range of protections: against short circuit, over-discharge of the battery, overheating and overload. Additionally, it has reverse polarity protection for both solar panels and the battery – minimizing the risk of damage and ensuring reliable operation of the entire system.

Ease of Use and Reliability

The Qoltec controller offers an intuitive interface and easy configuration of settings. This allows the user to have full control over the system operation and adapt it to their individual needs. The device is solidly made of high-quality materials (ABS and metal), which guarantees its durability and reliability. An additional advantage is the 24-month manufacturer's warranty, which confirms the high quality of the product and ensures peace of mind. It also has two USB ports for charging external devices.
