Key benefits and why you need it Maximise solar harvest: The 100A MPPT controller automatically finds and tracks the maximum power point, improving energy capture and overall system performance with up to 99.5% tracking efficiency. Convenient device charging: Dual USB 5V ports supply reliable charging for phones, tablets, and small electronics without needing additional adapters. Reliable, safe operation: Built-in protections guard your system and batteries against over-voltage, over-current, power failure, overcharging, deep discharge, reverse connection and overheating so your installation runs smoothly and securely. Simple monitoring and control: A backlit LCD with clock and 7 selectable working modes makes setup, status checks, and mode changes fast and straightforward. Core functions and performance MPPT technology: Advanced automatic voltage identification and tracking continuously optimises PV output so panels deliver more usable energy than conventional controllers. Power handling: 100A current capacity for robust performance with larger arrays and battery banks. USB charging: Dual 5V USB ports provide on-demand power for personal devices alongside the main solar charging function. User interface: Multifunctional LCD provides clear system readouts and access to seven working modes to match charging strategies and load behaviour. Compatibility and installation notes Designed to integrate with PV systems and battery banks; automatic voltage identification simplifies compatibility with a variety of system voltages and configurations. Compact form and straightforward controls make it suitable for wall- or panel-mounting in off-grid and hybrid installations. Durable enclosure and standard electrical connections support reliable everyday operation in typical solar environments. Typical applications Off-grid cabins and tiny homes: Maximise limited panel output, protect batteries, and keep devices charged while living remotely. RVs, caravans and boats: Efficiently manage solar charging aboard mobile platforms and provide convenient USB charging for onboard electronics. Small commercial or telecom sites and backup power: Improve energy harvest, protect critical batteries, and monitor system status with the integrated display. What makes it stand out High MPPT efficiency (up to 99.5%) combined with a 100A rating delivers strong performance for demanding small- to mid-sized systems. Dual-purpose utility: dedicated solar charge control plus convenient USB outlets for everyday convenience. Comprehensive protection suite and a clear, backlit LCD with clock and seven working modes make the controller both safe and adaptable to diverse installation needs.
