Working Temperature: -35 degrees Celsius to 60 degrees Celsius Package List: 1 x Controller 1 x Manual Note: 1. This controller is 12V/24V automatic identification. When installing for the first time please make sure that the battery has enough voltage so that the controller can recognize the correct battery type. In order to the service life of the battery once the battery voltage is lower than 8V the solar controller will automatically shut down. 2. Install the controller as close to the battery as possible to avoid voltage drop caused by excessively long wires and affect normal voltage judgment. 3. This controller is only suitable for various VRLA batteries (including openings gels etc.) please do not use it for other batteries (including lithium battery NI-MH battery 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 when it is running. The operating temperature of the controller is -35?C to +60?C. Please be careful to install the controller on a flat well-ventilated . 6. The LCD display of this controller has an error of 0.2V-0.3V but this is normal.
