Spec: Item Type: Solar Charge Controller Material: ABS USB Output: 5V Output Mode: USB Operating Temperature: -35+60 Scope Of Application: Solar Panels, Etc. Gross Weight: 147g/5.2oz Color: Black, Green How to Use: 1. The controller is 12V 24V auto adaptive, when first installed, please make sure the battery has enough voltage so that the controller can be recognized as the correct battery type.2. Install the controller as close to the battery as possible to avoid the voltage drop caused by long wires, which will affect the normal voltage judgment.3. This controller is only applicable to all kinds of batteries (including open, sealed, gel, etc.), please do not use it for other batteries (including lithium batteries, NiMH batteries, etc.).4. This controller can only use photovoltaic panel as charging source, please do not use DC or other power sources as charging source.5. The controller will be hot when running, please pay attention to install the controller on a flat, well ventilated surface.
