Smart MPPT Solar Charge Controller 30A - 12V 24V 36V 48V Auto-Detect for Home/RV/Off-Grid
Advanced Features for Professional Performance
This smart controller supports automatic voltage detection for 12V, 24V, 36V, and 48V battery systems, eliminating manual configuration errors. It features comprehensive protection against overcharging, over-discharging, short circuits, reverse polarity, and overheating. The durable construction ensures reliable operation in harsh environmental conditions, making it ideal for permanent off-grid installations as well as mobile applications.
Optimized Charging for All Battery Types
Engineered to work with multiple battery technologies, our MPPT controller provides optimized charging profiles for lead-acid (flooded, AGM, gel) as well as lithium-ion (LiFePO4) batteries. The sophisticated charging algorithm includes bulk, absorption, and float stages to ensure complete battery charging while maximizing battery lifespan.
