80A Solar Charge Controller 12V/24V/36V/48V Auto, 100V Max PV Input, LCD Display, Dual USB

Enhanced Energy Harvest with MPPT-Based Algorithm： 80A controller utilises an advanced MPPT-based algorithm to optimise the energy harvested from your solar panels. It automatically detects system voltage (12V/24V/36V/48V) and features dual USB 5V ports for convenient device charging. The unit is designed to improve overall solar energy utilisation in various environmental conditions. Clear LCD Monitoring & 7 Operational Modes：Monitor your system status easily via the backlit LCD screen, displaying real-time data including battery voltage, charging current, and temperature. Choose from 7 operational modes (such as timed lighting and load control) to automate your connected devices according to your specific requirements, day or night. Comprehensive Safety Protection：Built-in safety features protect against over-voltage (cut-off >32V), over-current, short circuits, and overheating (>65°C / 149°F). The robust housing and efficient natural heat dissipation ensure long-term reliability. Immediate power interruption occurs during fault conditions to safeguard your batteries and connected equipment. CRITICAL: Lead-Acid Optimised & Lithium Restrictions： 80A controller is primarily optimised for Lead-Acid batteries​ (Sealed, GEL, Flooded). For Lithium (LiFePO4): No user menu exists​ to manually adjust charging voltages; parameters are factory-predefined. Use with LiFePO4 is only permitted after verifying the maximum charge voltage with a multimeter​ and obtaining explicit approval from the BMS. If unsure, use Lead-Acid batteries only. Hybrid Charging Technology (MPPT+PWM) & Robust Build:Featuring a transparent hybrid design (MPPT algorithm + PWM output stage), this controller balances efficient solar harvesting with a robust, high-current build. The improved heatsink spacing enhances natural airflow, ensuring stable 80A performance. Ideal for off-grid homes, cabins, RVs, and remote solar installations.
