Efficient energy management in photovoltaic systems

The SmartSolar MPPT 250/85-Tr controller provides maximum input voltage up to 250V, which allows the use of higher voltage solar panels without the need for costly modifications to the system configuration. This product offers flexibility and excellent expandability for both home users and more advanced commercial systems.
High input voltage not only optimizes system configuration but also improves its energy efficiency, ensuring that every ray of sunshine is fully utilized for energy production.

Fast and safe battery charging

Thanks maximum charging current of 85A The SmartSolar controller is the ideal choice for medium-sized photovoltaic installations. It ensures fast battery charging while ensuring battery safety and longevity. Intelligent algorithms, including advanced technology MPPT (Maximum Power Point Tracking), adjust the speed and method of charging, which translates into optimal system operation in all conditions, even in partial shade or on days with reduced sunlight.

MPPT - Maximum power from solar panels

The technology used in the regulator MPPT allows for precise tracking of the maximum power point from photovoltaic panels, which means that the device constantly analyzes the panel voltage and automatically adjusts operating parameters to achieve the highest possible efficiency. This advanced solution allows the SmartSolar MPPT 250/85-Tr to operate even 30% more efficient than traditional PWM regulators, which translates into noticeably greater energy gains.

Innovative Battery Life algorithm

The regulator is equipped with an algorithm Battery Life which constantly monitors the battery charge status and takes care of them longevity This algorithm detects when the battery is undercharged and automatically adjusts the device's operation to restore its full capacity. This prevents deep discharge, which can shorten battery life. Each day, the algorithm adjusts the load disconnection and activation thresholds, allowing intelligent management of energy resources in the system.

Three-stage battery charging process

Thanks three-stage charging process, the SmartSolar MPPT 250/85-Tr regulator ensures that the battery charging is both quick, What safe:

1. Bulk Mode - The battery is charged at full power until it reaches the appropriate charge level.


2. Absorption Mode - Once close to full charge, the current is reduced to safely complete the process.


3. Float mode - When the battery is full, the voltage is reduced to a maintenance level, extending its life and readiness for further use.

Intelligent temperature compensation

Each SmartSolar MPPT 250/85-Tr controller is equipped with temperature sensor, which dynamically adjusts the charging voltage depending on external conditions. When temperatures drop, the controller automatically increases the voltage, and when temperatures rise, it reduces it. This feature is essential to ensure stable and long-lasting battery operation, regardless of environmental conditions.

System security and protection

Safety is a priority in every solar system, which is why the SmartSolar MPPT 250/85-Tr controller is equipped with a range of protective features. These protect the system from overcharging, deep discharge of batteries and also prevent damage caused by short circuits or reverse polarity of the photovoltaic panels. These advanced safeguards ensure the entire system operates smoothly for a long time, reducing the risk of costly repairs and extending the life of the batteries.

Remote monitoring and control - VE.Can and Bluetooth

The controller is equipped with VE.Can interface, which enables remote management and monitoring system parameters using a smartphone application. Thanks to the built-in function Bluetooth, users can easily adjust settings and monitor system performance without needing physical access to the device. This solution significantly simplifies the operation and management of the photovoltaic system, providing full control over every aspect of operation.
