Feature 1Automatically manage the work of solar panels and batteries in solar panels. Easy to set up and operate. 2Once the battery voltage drops below 8V, the solar controller will automatically turn off (the LCD will be unavailable at the same time), effectively extending the battery life. 3It has dual USB ports for 12V/24V, and the rated charging and discharging current is 60A. Please make sure that the battery has enough voltage so that the solar controller can recognize the normal battery type. 4The status and data are clearly indicated, and the mode and parameter configuration can be easily switched. 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. 5Double reverse current protection, low heat generation. All electronic components generate heat during operation, so it is best to shelter them to better dissipate heat and avoid direct sunlight or humid places.Item Type: Solar Charge ControllerMaterial: PlasticRated Voltage: 12V/24V AUTORated Current: 60AUSB Output Voltage: 5VDC Output Voltage: 12VVoltage of Solar Panels: 50VFloat Charging Voltage: 13.7V/27.4VLow Voltage Protection: 10.7V/21.4VLow Voltage Recovery: 12.6V/25.2VCharacteristic:No Load Loss:10mA; Loop Voltage Drop:170mVTemperature Compensation:-4mV/Cell/Working Environment:Operating Temperature: -20-60; Storage Temperature: 30-70; Humidity Requirements:90,no condensationInstallation Cable Area:7# AWG (10mm)3# AWG (25mm) .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 Manual
