Feature:1. MPPT Solar Charge Controller: Automatic focusing MPPT tracking charging, high charging efficiency, non-stop detection during charging, bidirectional focusing tracking.2. 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 glance.3. Dual USB Port: USB output: 5V/2A max, dual USB supply power to two mobile phones, tablet PCs, and other devices.4. Multiple conservation: Built-in overheating, overcurrent, short circuit, open circuit conservation, reverse connection conservation, when the fault is eliminated, the controller automatically recovers, does not damage the device.5. 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.6. Function: Bidirectional MOS tube anti-backflow circuit, high-power charging mode, ultra-low heat. A complete three-phase charge management, effectively protect the battery, the battery is more High quality.7. 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.Specification: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 conservation: Built-in overheating, overcurrent, short circuit, open circuit conservation, reverse connection conservation, 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).
