Solar charge controller Skyled MPPT 20A / 260/520W / 12V/24V LCD

Solar charge controller Skyled MPPT 20A / 260/520W / 12V/24V LCD, part no. 22MT2010BT

Skyled photovoltaic controller is designed for charging batteries from a connected solar panel system. This modern and multifunctional device performs charging based on the latest and most efficient MPPT charging technology.

The controller is equipped with a BLUETOOTH wireless communication function, allowing remote control and monitoring of operating parameters. The controller can be operated remotely via a smartphone app.

PRODUCT ADVANTAGES:

• Innovative maximum power point tracking technology
• (MPPT), tracking efficiency >99%, fully digital technology, high charging conversion efficiency up to 97%
• LCD display, easy reading of operating data
• Automatic 12V/24V detection
• Real-time energy statistics function
• Selection of flooded, gel or AGM batteries
• External temperature sensor and automatic temperature compensation
• Built-in temperature sensor – when temperature exceeds the set value, the charging current will be reduced to lower temperature and control regulator heating
• 4-stage charging: MPPT, boost, equalization, float
• In current limiting mode, when photovoltaic module power is too high and charging current exceeds nominal value, the controller will limit charging power to keep the system within the nominal charging current range
• Multiple load control modes: Standard, D2D (dusk to dawn), Timer and test mode
• Modbus protocol based on RS-485 maximizing communication capabilities
• Fully automatic electronic protection function
