Built-in over-current protection, short circuit protection, open protection, reverse connection protection, all of which are self-healing and do not damage the controller.6. Surge protection circuit, ultra-low heat generationSpecification:Material: ABS+PCsystem voltage: 12V automatic adaptation24V Charging current (optional): 10A/20A/30A Maximum PV voltage: 23V for 12V battery; 46V for 24V batteryIncrease charge voltage: 14.4V Variable voltage: 13.7V (default, adjustable)Discharge cut-off voltage: 10.7V (default, adjustable)Discharge recovery voltage: 126V (default, adjustable)Charge recovery voltage: 13VSlight-controlled PV panel with threshold on: 8V (light-controlled power-on has a delay)USB output: 2 USB outputs, 5V/2.5A (maximum)Standby current: lt; 10mA Working Temperature: -35 - +60°C Measurement: 125x112x3 4mm/4.92x4.41x1.34in Recommendations for Safe Use:1. This controller automatically recognizes 12V24V. When installing for the first time, please make sure the battery has enough voltage, so that the controller can recognize the corresponding battery type.2. Install the controller as close to the battery as possible to avoid voltage drop caused by too long wires and affect the normal voltage.3. This controller is only suitable for all types of realization-accumulators (including holes, gaskets, gels, etc.). 4. This controller can only use PV panels as a charging source. Do not use DC or other power sources as a charging source.5. The controller gets hot when it is running, care should be taken to install the controller on a flat, well-ventilated surface. Note:Due to the different monitor and light effect, the actual color of the item may be slightly different from the color showed on the pictures. Please allow 1-3cm measurement deviation due to manual measurement.1 X Solar Controller
