MPPT 20A Bluetooth Solar Charge Controller, Dual USB, Automatic Identification, 12V/24V Solar Panel Regulator, Max Voltage 60V, LCD Screen MRL20

【20A MPPT Solar Charge Controller】: This MPPT solar charge controller has a built-in Bluetooth module that allows you to remotely monitor the operating status of your solar panels via the "Solar Power" app. The controller is compatible with 12V/24V system voltage, has a rated discharge current of 20A, and a maximum open-circuit voltage of 60V. It features dual 5V/2A USB outputs, supporting charging of mobile phones and batteries within the solar system. 【LCD Display】: The MPPT 100/30 charge controller features a backlit LCD screen, allowing you to intuitively understand the controller's operating status. The panel is equipped with a temperature sensor for real-time temperature monitoring, and the controller offers simple button operation and adjustable working parameters. Thickened heat sink to protect against overheating.
【MPPT Control Algorithm】: MPPT regulator with advanced MPPT tracking technology, tracking efficiency up to 99%, circuit energy conversion efficiency up to 98%. Even when the solar panel is blocked, it can still accurately track the maximum power point.
【Applicable to a wide variety of batteries】: Solar charge controller supports lithium ternary batteries, lithium iron phosphate batteries, colloidal batteries, sealed batteries, and open batteries (12V/24V battery voltage automatically detected). Supports trickle charge, undervoltage charge, and equalization charge to better protect the battery. Solar regulator with 4 charge control modes: all-day operation, light-only control, light-time control, and reverse control.
【Multiple Functions of [Protection]: This 12V solar battery charge controller features PV panel reverse polarity protection, battery reverse polarity protection, battery overvoltage protection, battery over-discharge protection, and overcharge protection.
