40A MPPT 12V/24V Car DC Input Solar Charge Controller with Built-in Bluetooth Module, Parameter Adjustable LCD Display LED Display

12/24V MPPT with 99% tracking efficiency: 12V/24V 40A MPPT solar charge controller has advanced tracking technology with tracking efficiency of up to 99% and a peak conversion efficiency of up to 98%. It improves the energy usage ratio by 15% to 20% compared to traditional PWM controllers. Bluetooth remote control: The solar charge controller 12V MPPT is equipped with an RS485/Bluetooth communication port that can connect to the Bluetooth adapter (included) to display the real-time status of the solar panel and remotely monitor the battery and load. The built-in Bluetooth module makes it easy to use. LCD display: charge controller solar 12 V MPPT is equipped with an LCD display and LED indicators and has 4 control buttons. The screen provides a clearer view of the data and the LEDs are useful for monitoring the status of each device. Supports multiple battery types: 12V/24V 40A MPPT solar charge controller has LiFePO4 battery charging mode as standard, which is suitable for most of the lithium iron phosphate batteries on the market. At the same time, it can be compatible with other types of batteries by selecting the parameters, such as: sealed, gel type lead-acid batteries. Environmentally friendly and heat-dissipating multifunctional housing: The MPPT solar charge controller is made of aluminium alloy to ensure heat dissipation while reducing power loss. And it can work at full load in a temperature range of -31°F to 113°F. The controller has built-in protection for reverse polarity, over-current, over-voltage, short circuit protection, over temperature, which provides safety devices for the whole solar system.
