100A MPPT Solar Charge Controller Key benefits Maximizes energy harvest from solar panels using an advanced MPPT maximum power point tracking algorithm. Automatically detects system voltage levels 12V, 24V, 36V, and 48V, removing the need for manual configuration. 100 amp output capacity supports larger PV arrays and battery banks for reliable charging and system operation. Built in 5V USB charging ports provide convenient power for small devices without additional adapters. Fast, adaptive tracking in variable environmental conditions to improve overall conversion and charging performance. Main functions and features MPPT tracking: Continuously finds the operating point of the PV array to extract maximum available power. Automatic voltage identification: Autoswitches among 12V, 24V, 36V, and 48V system configurations for flexible compatibility. USB outputs: 5V charging ports for phones, tablets, and other USB powered devices. current handling: 100A rating suited for mid to large residential and off grid systems. Compatibility and performance Designed for use with photovoltaic systems and battery charging installations that operate at 12V, 24V, 36V, or 48V. Supports systems requiring up to 100A charge current. Optimized for environments with variable sunlight and partial shading through rapid MPPT response. Practical use scenarios Off grid cabin or small home: Manage a PV array and battery bank to keep batteries charged and supply DC loads, with USB ports for charging devices. Recreational vehicle or boat: Integrate with on board solar panels to maintain the house battery bank and offer convenient USB charging while traveling. Remote equipment or field site: Power and charge batteries for lighting, monitoring equipment, or communications gear where stable solar charging and automatic voltage handling are needed. Why choose this controller Provides efficient MPPT tracking and wide voltage compatibility to simplify system setup and increase usable energy from solar panels. 100A capacity and USB charging make it suitable for a range of applications from mobile setups to larger off grid systems. Automatic detection and fast tracking reduce manual configuration and help maintain reliable charging in changing conditions. What to consider Ensure system wiring and battery bank are rated appropriately for a 100A controller and that PV array voltage is compatible with the controller input range.
