High-performance 100A MPPT Solar Charge Controller — built to maximize energy harvest, protect your batteries, and make system monitoring simple. Key benefits Maximizes solar output: advanced MPPT algorithm quickly finds and maintains the PV system’s maximum power point, improving energy capture and overall system efficiency (tracking efficiency ≥ 99.5%). Protects batteries and system components: multiple safety layers reduce risk of damage from overcharge, overcurrent, surge events, reverse connection, overheating, deep discharge, and power interruptions. Easy setup and monitoring: an LCD clearly shows operating data and status so you can verify performance and adjust settings without guesswork. Flexible use: automatically detects system voltage and supports common battery types, making it suitable for many small- to medium-scale off-grid and backup systems. What it does (functions and performance) 100A MPPT controller: handles large PV currents with an efficient MPPT algorithm for 12V / 24V / 36V / 48V systems (automatic voltage identification). High tracking accuracy: dual USB 5V ports plus PV inputs track the maximum power point with at least 99.5% efficiency, improving usable energy from your solar array. Battery charging options: compatible with Gel and Flooded battery chemistries and designed for reliable battery charging control. Comprehensive protection suite: surge/battery protection, overcurrent protection, power-failure protection, overcharge protection, low-discharge (deep discharge) protection, reverse-connection protection, and overheating/temperature protection. Clear LCD readout: dynamic display of working mode, battery voltage, PV charge current, battery (load) current, controller operating temperature, and delay time for quick diagnostics and status checks. Compatibility and practical details Voltage compatibility: automatic identification for 12V / 24V / 36V / 48V systems. Charging compatibility: supports Gel and Flooded battery types and general battery charging control. User interface: LCD for real-time monitoring of key parameters and simple status verification. Device outputs: dual 5V USB ports for charging small devices directly from the controller. Typical use scenarios Off-grid cabin or tiny home: maximize solar energy, keep house batteries protected from overcharge and deep discharge, and monitor system status from the on-board LCD. RVs and caravans: automatic voltage detection and compact control with USB charging ports make it easy to manage multiple battery configurations and charge mobile devices on the road. Remote systems and backup power: reliable protections and high MPPT efficiency help maintain battery health and deliver consistent power for pumps, telecom equipment, or emergency backup systems. Why choose this controller Solid MPPT performance for better energy yield from your panels. Robust protection features to extend battery life and reduce risk of system failure. Clear, user-friendly display for fast verification and troubleshooting. Versatile voltage and battery compatibility for a wide range of solar charging installations.
