SmartSolar MPPT 75/10

The SmartSolar MPPT 75/10 Charge Controller is an advanced device designed to optimize battery charging using solar energy. Built-in MPPT (Maximum Power Point Tracking) technology maximizes charging efficiency, making it an ideal solution for mid-sized photovoltaic systems. High Input Voltage and System Flexibility The SmartSolar MPPT 75/10 controller supports a maximum input voltage of up to 75V, allowing it to seamlessly work with higher-voltage solar panels. This provides greater flexibility, allowing you to configure the system to your individual needs. Automatic voltage adjustment (12V or 24V) ensures ease of use without the need for manual adjustments.

Advanced Charging Algorithms

The SmartSolar MPPT 75/10 charge controller uses the latest charging algorithms that automatically adjust parameters depending on the battery charge level. The device operates in three modes: Bulk, Absorption, and Float, ensuring maximum efficiency and battery protection. Bulk mode provides fast charging at maximum power, Absorption maintains a stable voltage, and Float mode maintains the charge, minimizing energy consumption.

MPPT Technology – Maximum Power from Solar Panels

Thanks to the use of MPPT technology, the charge controller automatically adjusts its settings to current lighting conditions, maximizing charging efficiency even in changing weather conditions. This significantly increases the amount of energy that can be produced from solar panels, especially in partial shade.

Intelligent Battery Management

The Battery Life function is an advanced algorithm that monitors the battery's condition and dynamically manages its charge and discharge cycles. The controller monitors the battery's charge level and makes adjustments to protect it from excessive discharge and ensure a full charge every few days. This protection significantly extends battery life, which is crucial for the long-term stability of the photovoltaic system.

Bluetooth Communication and Monitoring

The integrated Bluetooth interface allows for easy monitoring and programming of the controller using a smartphone app. You can continuously monitor operating parameters such as battery voltage, charging current, and the power generated by the solar panels. Additionally, the optional MPPT Control allows for expanded monitoring and management capabilities, providing complete control over your solar system.

Built-in Protections

The SmartSolar MPPT 75/10 controller is equipped with numerous safety features that protect the battery against overcharging, deep discharge, and overloading. Designed for long-term and reliable operation, the device is an ideal choice for those seeking a robust solar energy management solution.

Battery Protection and System Protection

The device offers a range of safety features, such as short circuit and overload protection. If an abnormality is detected, the controller immediately disconnects the power supply, protecting both the battery and the entire system.
