Feature 1Can automatically manage the work of solar panels and batteries in the solar system. Easy to set up and operate. In order to protect the service life of the battery, once the battery voltage drops below 8V, the solar charge controller will automatically shut down (LCD cannot be used at the same time). This is a very smart solar panel unit! 2Multiple electrical protection functions, if the solar controller is set to 12V, when the battery voltage reaches 14.4V or 14.5V, the solar controller will stop charging and play a protective role. If it does not enter the floating state, please don't worry, the solar charge controller has a voltage limit value, if the battery voltage reaches 14.4V or 14.5V, it will not charge. 3Easy to install and operate, can clearly indicate status and data, and can easily switch modes and parameter configuration. Install the solar charge controller as close to the battery as possible to avoid voltage drop due to excessively long wires and affect normal voltage judgment. 4It has good heat dissipation, double reverse current protection and low heat generation. All electronic components generate heat during operation, so it is best to shield them to better dissipate heat, avoid direct sunlight or put them in humid places. 5Equipped with LCD display screen, for clear display. With compact shape, take up no space, and also easy to carry with.Item Type: Solar Charge ControllerMaterial: PlasticVoltage:12V/24V .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Solar Charge Controller1 x ManualNote If the solar charge controller is set to 12V, when the battery voltage reaches 14.4V or 14.5V, the solar charge controller will stop charging and play a protective role.
