Product: Solar controller Color: Blue (100A) Material: Plastic Size: 20 x 20 x 7 cm Battery voltage: Automatic identification of 12V, 24V, 36V, 48V Charging current options: 80A or 100A Overview This solar charge controller uses advanced maximum power point tracking (MPPT) technology to maximize energy harvest from solar panels, with tracking efficiency exceeding 99.5 percent. The unit features an LCD screen that displays realtime operating data and status, dual USB 5V charging ports for small devices, and broad battery compatibility for flexible system use. Key benefits Efficient energy use: MPPT tracking over 99.5 percent optimizes panel output and reduces energy loss. Easy monitoring: The LCD screen shows battery voltage, charging current, charging state, and error or protection status at a glance. Plug and play voltage selection: Automatically recognizes 12V, 24V, 36V, or 48V systems so no manual switching is required. Wide battery compatibility: Supports Seal, GEL, Flooded, and LifePO4 battery types for use with many battery chemistries. Device charging: Dual USB 5V output provides convenient charging for phones, tablets, and other USB devices. Protection built in: Integrated overvoltage protection, overcurrent protection, and temperature protection help prevent damage during charging. Flexible operation: Seven selectable working modes allow configuration for different load and charging strategies.
