When charging make sure that the surface of the solar panel faces the sun.2. Avoid contact with impact objects and other acuminate objects.3. Do not bend the solar panel too much to avoid breaking.4. Keep the surface of the panel clean when charging to maintain the high efficiency of solar power generation. Controller considerations:1. Controller automatically recognizes 12V/24V. 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 protect 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 the voltage drop caused by the excessive length of wire which affects the normal voltage judgment.3. Controller is only suitable for various batteries (including openings seals gels etc.) please do not use it for other batteries (including lithium batteries nickel hydrogen batteries etc.).4. Controller can only use photovoltaic panels as the charging source do not use DC or other power sources as the charging source.5. Controller will generate heat when it is running. Operating temperature of the controller is 35C to +60C. Please pay attention to install the controller on a flat well ventilated surface.6. LCD display of this controller has an error of 0.2V0.3V but this is normal.
