Package List: 1 x Solar Controller 1 x Chinese And English Manual Note: 1. The controller automatically adapts to 12V/24V, or another version of 12/24/36/48/60V to manually set the appropriate battery charging mode. When installing for the first time, please make sure that the battery has enough voltage to start and automatically set the controller parameters. 2. Install the controller as close to the battery as possible to avoid voltage drop caused by too wires and affect the normal voltage judgment. 3. This controller is suitable for all kinds of lead acid batteries (including opensealed colloidal batteries). If you need to be familiar with the battery characteristics of the lithium battery, you must set the charging parameters before using it. 4. The controller can only use
