Bi directional MOS tube anti backflow circuit high power charging mode low heat generation. 5Multiple Protection: Controller is with built in overheat protection overcurrent protection short circuit protection open circuit protection reverse connection protection when the fault is eliminated self recovery type no damage to the controller. Specification Item Type: Solar ControllerMaterial: ABSRated Charging Current: 30ARated Discharge Current: 10AStandby Current: <10mAUSB Output: 5V 2A MaximumOperating Temperature: -36 to +60 Package List 1 x MPPT Solar Charge Controller Note 1. The controller is 12 or 24V automatic adaptation when first installed please make sure the battery has enough voltage so that the control can recognize as the correct battery type.2. Install the controller as close to the battery as possible to avoid the voltage drop caused by the long wire which will affect the normal voltage judgment.3. The controller is suitable for various acid batteries (including open sealed gel etc.) if charging other batteries you must be familiar with their battery characteristics and set to the appropriate charging parameters. For example charging 12V lithium battery prohibit output protection setting 9.5V full protection 122V battery down when the start of charging 11.5V.4. This controller can only use photovoltaic panels as the charging source please hurry to use DC or other power sources as the charging source.5. The controller will be hot when running please pay attention to install the controller on a flat well ventilated face.
