Features:MPPT Solar Charge Controller: Automatic focusing MPPT tracking charging, high charging efficiency, non-stop detection during charging, bidirectional focusing tracking.LCD Display: The industrial-grade master control chip, AD sampling precision, temperature, level 16 charging current, discharge current, the cumulative output real-time display, large LCD display screen shows the data at the same time, be clear at a glanceDual USB Port: USB output: 5V/2A max, dual USB supply power to two mobile phones, tablet PCs, and other devices.Multiple Protection: Built-in overheating, overcurrent, short circuit, open circuit protection, reverse connection protection, when the fault is eliminated, the controller automatically recovers, does not damage the device.Applicable Battery: This controller is suitable for all kinds of lead-acid batteries( including open, sealed, gel and other batteries). If you charge a lithium battery, you must be familiar with its battery characteristics, and you must set the charging parameters before you can use it.Function: Bidirectional MOS tube anti-backflow circuit, high-power charging mode, ultra-low heat. A complete three-phase charge management, effectively the battery, the battery is more durable.APP Remote Control: MPPT solar charge controller built-in BT/WiFi smart control system, can download App, remote operation controller parameters, remote operation settings, and check the parameters. Can view cloud data records for 7 days.Warm Tips:1. Please keep it in cool and well ventilated place to maintain good heat dissipation.2. Ensure your battery has enough voltage for the controller to recognize the battery before first installation.Specifications:Charge Current: 30A/ 40A/ 50A/ 60A(Optional)Voltage: 12V/24V/36V/48V/60VSelf-Consume: <10MAUSB Output: 5V/ 2A MaxOperating Temperature: -10 ~ +60Material: ABS+ metalPackage Size: 13.3* 7* 3.5 cm/ 5.24* 2.75* 1.38 inchPackage Weight: 150g/ 5.29ozPackage List:1* Controller1* User Manual(English)
