Smart MPPT Solar Controller 30A 40A 50A 60A for RV, Boat, Home Solar Power Systems
High-performance MPPT solar charge controller designed for off-grid solar systems in homes, cabins, RVs, boats, and telecom sites. Supports multi-voltage battery systems and offers comprehensive protections for long-term, reliable operation.
Key Advantages
Advanced MPPT with 99% Tracking Efficiency — intelligently extracts up to 30% more energy than PWM and auto-optimizes under sunny/cloudy conditions.
Wide Battery & System Compatibility — works with 12V/24V/36V/48V systems; supports sealed/GEL/flooded lead-acid and LiFePO4 (optional); PV input up to 100V DC for series panels.
Smart Battery Management — 4-stage charging (bulk/absorption/float/equalization) helps extend battery life by up to 200% with temperature compensation (-20°C ~ 60°C).
Military-Grade Protection — triple reverse-polarity (PV/battery/load), 4000V lightning surge, and over-current/short-circuit/overheat with auto-recovery.
User-Friendly Operation — 3.2″ LCD real-time data (PV V / charge A / battery temp), dual USB 5V/3A, optional Bluetooth/WiFi app monitoring.
