Feature: 1. Automatically manage the work of solar panels and batteries in solar panels. Easy to set up and operate. 2. Once 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. 3. It 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. 4. The 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. 5. Double 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.
