Key benefits — why you need this MPPT charge controller Maximizes solar output: MPPT tracking with at least 99.5% tracking efficiency pulls the most power from your panels so batteries charge faster and solar yield improves. Protects your system and battery life: built-in safeguards against overvoltage, overcurrent, power failure, overcharging, deep discharge (low voltage), reverse connection and overheating reduce failure risk and costly battery replacement. Simple monitoring and control: an intuitive LCD shows live operating data (battery voltage, discharge current and status), making it easy to check performance and fine-tune settings. Flexible and future-ready: automatic detection of system voltage from 12V to 48V and wide battery support make the controller suitable for many off-grid and mobile setups. What it does (core functions) Advanced MPPT algorithm continuously tracks the solar array’s maximum power point to increase charging efficiency and reduce wasted energy. Automatic 12V/24V/36V/48V recognition so the controller configures itself to your system without manual voltage switching. Dual USB ports provide convenient fast charging for phones and devices while the controller manages power for the rest of the system. Full protection suite: prevents damage from overvoltage, overcurrent, power failure, overcharge, low discharge, reverse wiring and overheating. Compatibility and performance Battery types: supports gel and flooded batteries and is compatible with common battery chemistries used in solar setups. Voltage range: auto-detects and operates across 12V to 48V systems. Efficiency: MPPT tracking efficiency of no less than 99.5% for reliable, high-performance charging. Interface: clear LCD presents dynamic operating data (battery voltage, discharge current and working status) for easy monitoring and accurate adjustments. Design and usability User-friendly LCD makes status and metrics easy to read and understand; quick access to settings lets you adapt charging profiles to different battery needs. Dual USB ports for device charging reduce the need for additional accessories during travel or remote use. Compact, installation-ready form factor fits typical residential, mobile and small commercial solar installations. Practical applications — how customers use it Off-grid cabins and tiny homes: maximize solar harvest and protect batteries during seasonal use while providing USB charging for devices. RVs, campervans and boats: automatic 12–48V detection and compact size simplify integration into mobile electrical systems and keep batteries healthy on the move. Remote equipment and field sites: reliable MPPT charging and comprehensive protections maintain battery health where maintenance is difficult. Why this controller stands out High MPPT tracking efficiency (≥99.5%) that directly improves charging speed and system uptime. Comprehensive protection features that reduce risk of system failures and extend battery life. Simple LCD interface and dual USB ports for practical everyday use across a variety of solar setups. What to expect out of the box A ready-to-install MPPT charge controller with LCD display and dual USB ports, configured to work automatically with 12V–48V solar systems and compatible battery types. If you need a compact, reliable MPPT controller that increases solar energy capture, safeguards your batteries, and provides easy monitoring for off-grid, mobile or remote systems, this unit delivers efficient charging and robust protection.
