TheVolt Polska 3IPSMPPT20 / 20A / 12-24VDC Solar Panel Charging Controller is designed for charging batteries from a connected solar panel kit. This modern and multifunctional device charges based on the latest and most efficient MPPT charging technology.By optimising the charging process, the controller effectively extends battery lifetime compared to standard PWM controllers.The SOL MPPT 20A features a BLUETOOTH wireless function, which allows you to remotely control and view the controller's parameters.

Key features:

• State-of-the-art MPPT (Max Power Point Tracking) tracking technology. The combination of multiple tracking algorithms allows fast and accurate tracking of the maximum power
• Innovative Max Power Point Tracking (MPPT) technology, conversion/tracking efficiency > 99.9%
• Clear LCD display showing the most important operating parameters
• Automatic detection of connected battery voltage 12V/24V
• For use with GEL, AGM, lithium and liquid electrolyte batteries
• Extends battery life thanks to temperature sensor with automatic temperature compensation (if the temperature exceeds the set value, the charging current will decrease to reduce the temperature)
• Controller is protected against overheating thanks to the integrated power-down function
• Four-stage charging: MPPT, BOOST, Equalization, Float
• Multiple connected load control modes: always on, dusk to dawn, night and manual
• Fully automatic protection (short circuit, temperature, overload) to avoid exceeding the rated charging power and current

• Multiple load control modes: always on, street lighting, user mode
• IoT wireless or Bluetooth connectivity (models with VT index). Thanks to the IoT wireless function, the controller can be connected remotely via IoT/GPRS
• Monthly fee data can be calculated and displayed in groups and graphs
• Based on the standard Modbus RS-485 protocol with RJ11 interface for maximum connectivity needs in various applications.
• Excellent electromagnetic compatibility and thermal design
