Dual USB output, current up to 2.5A, support Apple mobile phone charging 4. Complete 3-stage charging management 5. Built-in over-current, short-circuit protection, open-circuit protection, and reverse connection protection, all of which are self-recovery and will not damage the controller 6. Anti-backflow circuit, ultra-low heat generation. System connection 1. Connect the positive and negative poles of the battery to the controller as shown in the figure, and the controller will automatically detect the battery voltage 2. Connect the positive and negative poles of the load to the controller according to the diagram, and be careful not to reverse them 3. Connect the solar panel to the controller according to the picture Safe use advice 1. The controller is 12V/24V automatic recognition, when installing for the first time, please make sure the battery has enough voltage so that the controller can recognize the correct battery type 2. Install the controller as close to the battery as possible to avoid voltage drop caused by too long wires and affect normal voltage judgment 3. This controller is only suitable for various lead-acid batteries (including open, sealed, gel, etc.) 4. This controller can only use photovoltaic panels as the charging source, do not use DC or other power sources as the charging source 5. The controller will generate heat during operation, please pay attention to install the controller on a flat and well-ventilated surface
