Features:- Acomplete three-phase charge management, effectively protect the battery, the battery is more durable.- 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.- Bidirectional MoS tube anti-backflow circuit, high-power charging mode, ultra-low heat.Specification:Name: MPPT dual USB LCD display automatic solar controllerBattery voltage: 12V/24V automatically adaptsMaterial: ABSProduct color: blue + blackCharging current: 10A, 30A, 50A, 60A, 100A (variable parameter)USB output: 5V/2AWorking temperature: -35+60℃Product size: 170 x 95 x 40 mm / 6.69 x 3.74 x 1.57 inchesNet weight: 270gGross weight: 320gPacking size: 175x100x45mmPacking: color boxPacking list:MPPT solar controller x1Chinese and English manual x1Notice:1.Make sure your battery has enough voltage for the controller to recognize the battery type before first installation.2. The battery cable should be as short as possible to minimize loss.3. The controller is applicable to various lead-acid batteries (including openings. seais, geis, etc.). If you charge other batteries you must be familiar with the battery characteristics and set the appropriate charging parameters.For example: charge 12V lithium battery, inhibit the output protection setting 9.5V full of protection 12.2V, start charging voltage 11.5V when the battery drops.4. The charge regulator is only suitable for regulating solar modules Never connect another charging source to the charge regulator.
