Package List: 1 x Solar Charge Controller1 x Light 1 x Manual Note: 1. This controller is 12, 24V automatic adaptation. When installing for the first time, please ensure that the battery has enough voltage so that the control can identify the correct battery type.2. The controller shall be installed as close to the battery as possible to avoid voltage drop caused by too long wire, which will affect normal voltage judgment.3. This controller is applicable to all kinds of acid batteries (including openings, colloids, etc.). If you charge other batteries, you must be familiar with their battery characteristics and set appropriate charging parameters. For example, it is forbidden to charge 12V lithium battery, set 9.5V for output protection, 122V for full charge protection, and 11.5V for start up charging when the battery drops4. This controller can only use photovoltaic panels as the charging source, please do not use DC or other power supplies as the charging source.5. The controller will generate heat when running. Please pay attention to installing the controller on a flat and well ventilated surface.
