100A MPPT Solar Controller — High-efficiency charge control with clear LCD display and robust protection Key benefits Maximise solar energy harvest: Advanced MPPT algorithm boosts charging efficiency to 99.5% or higher, extracting more power from your panels than PWM controllers. Protect your battery and system: Built-in protections reduce risk of overcharge, overcurrent, surges, deep discharge, and overheating — keeping batteries and PV equipment safe. Easy to monitor and configure: Backlit multifunction LCD displays operating data and status indicators simultaneously so you can view and adjust settings on the spot. Flexible and compatible: Automatic identification for 12 V, 24 V, 36 V and 48 V systems makes installation straightforward across a wide range of off-grid applications. Core features 100A MPPT controller with maximum point tracking technology for optimal solar energy collection. Automatic system voltage detection: supports 12 V / 24 V / 36 V / 48 V. MPPT tracking efficiency ≥ 99.5%. Multifunctional backlit LCD: shows working mode, battery voltage, photovoltaic charging current, operating temperature and other status indicators at a glance. Seven selectable working modes including charging mode, light control mode and manual control mode to match different system requirements. USB 5V charging port for auxiliary device charging. Multiple protection functions: surge protection, overcurrent protection, overcharge prevention, deep-discharge (deep DIS) protection, overheating protection and secure connection features to prevent damage to battery and PV components. User-friendly design: simultaneous display of operating data and status indicators for quick system checks and straightforward management. Why customers choose this controller Better energy yield: The high-efficiency MPPT algorithm captures more usable energy from solar panels, improving battery charge times and system performance. Safer battery life: Integrated protections help prevent common causes of battery failure and reduce maintenance needs. Versatile control: Multiple modes and clear on-screen data let you tailor behaviour for lighting, charging schedules or manual operation without additional hardware. Plug-and-play compatibility: Automatic voltage recognition and universal protections make it suitable for a range of system sizes and battery banks. Typical applications Off-grid homes and cabins: Keeps battery banks charged efficiently while protecting batteries from overcharge or deep discharge; ideal for household lighting, inverters and appliance loads. RVs, boats and mobile setups: Compact, clear display and USB charging make it convenient for vehicles or marine environments where space and usability matter. Small commercial or agricultural systems: Reliable MPPT charging and multiple working modes support pumps, lighting systems and remote equipment with better uptime and lower battery stress.
