Bluetooth solar MPPT charge regulator Lumiax Win500 20A

The LUMIAX solar controller is used to control the operation of autonomous photovoltaic systems. Provides adequate charging current for the battery and additionally protects against deep discharge or overcharging of the battery. Equipped with MPPT regulator with advanced maximum power point tracking system.
This solution enables a much more efficient 30-45% charging compared to PWM regulators.

External temperature sensor included - used to optimize the operation of the regulator and select appropriate operating parameters

Main features

• Innovative Max Power Point Tracking (MPPT) technology, tracking efficiency> 99.9%
• Automatic 12/24V recognition
• LED bar for easy reading of charge status and battery information
• Fully digital technology, high charging conversion efficiency up to 98%
• Waterproof design, suitable for indoor or outdoor use
• Use with liquid, gel or AGM batteries
• 4-stage charging: MPPT, boost, equalize, float
• External temperature sensor and automatic temperature compensation
• Modbus protocol based on RS-485 to maximize communication possibilities.
• Built-in temperature sensor, when the temperature exceeds the set value, the charging current will be reduced to lower the temperature, so as to control the temperature rise of the regulator
• Easy bluetooth communication
• In the charging current limitation mode, when the power of the photovoltaic modules is too high and the charging current exceeds the nominal value, the device will limit the charging power, which allows the system to operate within the nominal charging current range.
• Multiple Receiver Control Modes: Standard, D2D (Dusk to Dawn), Timer and Test Mode
• Fully automatic electronic protection function
