This controller is 12V/24V automatic adaptation, when you first install, please make sure that the battery has enough voltage, so that the controller can recognize the correct battery type. Install the controller as close to the battery as possible to avoid voltage drop caused by too long wire, affecting the normal voltage judgment. 3. This controller is only applicable to all kinds of lead-acid batteries (including open, sealed, colloidal, etc.), do not use on other batteries (including lithium batteries, nickel-metal hydride batteries, 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. 6. The controller will heat up when running, please pay attention to install the controller on a flat and well-ventilated surface. Menu key: Used to switch the parameter interface, or hold down for 5 seconds to enter or exit the parameter setting. Up: On the parameter setting screen, tap once to make the parameter go forward. Add one more gear. Scroll down: On the parameter setting screen, tap once to move the parameter up one step. List: 1* solar controller
