BlueSolar MPPT 75 / 15

brands Victron Energy is a compact and versatile device that offers advanced energy management features for photovoltaic systems. Thanks to the use of technology MPPT (Maximum Power Point Tracking) This controller optimizes the charging process, enabling maximum utilization of solar energy. Designed for small and medium-sized solar systems, the controller ensures high operating efficiency and reliability even in harsh weather conditions.

High input voltage - greater system flexibility

Regulator BlueSolar MPPT 75/15 supports input voltage up to 75V, which allows for more flexible configuration of photovoltaic systems. Thanks to the possibility of connecting panels with higher voltage, users can make the most of available solar energy resources, adapting the system to the specific needs of your installation. This solution is perfect for smaller installations where both efficiency and flexibility are important.

Maximum charging current 15A - fast battery charging

The regulator offers a maximum charging current of 15A, which enables quick and safe charging of batteries in medium-sized systems. Fast battery charging is crucial in situations where charging time is crucial for the continuous operation of the system. The regulator ensures stable and safe charging, protecting the batteries from overcharging, which increases their lifespan.

Advanced MPPT algorithms - maximizing charging efficiency

Technology MPPT used in the regulator BlueSolar MPPT 75/15 constantly monitors and optimizes the voltage and current from the solar panels, allowing for maximum power. MPPT algorithms can increase charging efficiency by up to 30% compared to traditional PWM controllers, which is particularly advantageous in conditions of variable sunlight or partial shading of the panels.

Battery Life Algorithm - protecting batteries and extending their lifespan

Regulator BlueSolar MPPT 75/15 has been equipped with advanced Battery Life algorithm, which ensures proper battery charging cycles. This algorithm prevents undercharging by monitoring the battery charge status and automatically adjusting load disconnection and reconnection thresholds. Thanks to this solution, the batteries are protected against excessive discharge, which significantly extends their lifespan.

Three-stage charging process - precise energy control

Charging process in the regulator BlueSolar MPPT 75/15 is divided into three phases, which ensures precise energy management:

1. Bulk Mode - intensive charging, which aims to restore the battery to its full capacity as quickly as possible.


2. Absorption Mode - DC charging, which stabilizes the battery charge level.


3. Float mode - a maintenance phase that keeps the battery at a safe charge level, minimizing the risk of overcharging.

Security and built-in temperature sensor - full system protection

Regulator BlueSolar MPPT 75/15 is equipped with safety features that protect both the batteries and the entire system from damage. The device is protected against output short circuit, overheating and exceeding the permissible temperature, which increases the reliability and safety of the system's operation. Additionally, a built-in temperature sensor automatically adjusts the charging voltage depending on weather conditions, protecting the batteries from overheating and extending their lifespan.

Optional accessories - full system control and monitoring

The controller can be extended with additional accessories that enable more advanced system management:

• Smart Battery Sense - a wireless sensor that monitors battery voltage and temperature and automatically adjusts charging parameters for optimal performance.


• MPPT Control - an external display that allows you to monitor and control key system parameters, such as battery voltage, solar panel power and daily energy yield.
