Efficient MPPT Solar Controller with USB Port, 100A Regulator for 12V, 24V, 36V, and 48V Solar Panels, Backlit LCD Screen

1. MPPT Technology: This 100A MPPT solar controller utilizes an advanced MPPT maximum power point tracking algorithm, automatically identifying 12V, 24V, 36V, and 48V voltages. Two 5V USB charging ports enable rapid tracking of the PV system's maximum power point in any environment, with a tracking efficiency of at least 99.5%. This significantly improves the energy utilization efficiency of solar systems. 2. MULTIFUNCTIONAL DESIGN: A multifunctional LCD screen with backlight and clock display offers 7 operating modes: charging mode, light control mode, light control mode, delay control mode, universal control mode, manual control mode, and synchronization control mode. 3. SAFETY VOLTAGE PROTECTION: MPPT solar controller with voltage protection, including battery overvoltage and overcurrent protection, power failure protection, overload protection, deep discharge protection, reverse connection protection, and overheat protection. 4. USER-FRIENDLY DESIGN: LCD screens are designed to dynamically display operating data and device status. Displays controller parameters (operating mode, battery voltage, photovoltaic charging current, battery discharge current, product operating temperature, delay time). 5. MULTIPLE BATTERY CHARGING OPTIONS: Compatible with GEL, flooded, and other batteries. Specifications: Item Type: Solar Charge Controller Material: ABS Rated Current: 100A Maximum Solar Input (Voc): 15-23V (12V battery); 30-45V (24V battery); 45-69V (36V battery); 60-90V (48V battery) Maximum photovoltaic input power: 1200W (12V battery); 2400W (24V battery); 3600W (36V battery); 4800W (48V battery) Operating Instructions: 1. Charging Method: Discharging must not be allowed under any circumstances. 2. Light Control Mode: When the controller detects night, it delays for ten minutes and then begins discharging; when it detects day, it waits ten minutes and then stops discharging. 3. Light and Delay Control Mode: When the controller detects night, it will delay for ten minutes before beginning discharge and counting down (if the timer reaches 0), discharging will stop. The maximum delay is 23 hours and 59 minutes. 4. General control method: Always maintain discharge without any faults. 5. Manual control mode: Use "▼" to check if discharge is necessary. 6. Timer control method: Regularly turn the discharge on or off. 7. Test mode: Same as the lighting and delay control modes, but only loses a ten-minute delay. 8. The controller always discharges under low-voltage protection. The touch screen "▼" remains active for 5 seconds, and discharge continues. Package list: 1 x controller
