EBay Product Description: This 60A MPPT solar charge controller delivers ultra-efficient power management for off-grid solar systems, featuring advanced Maximum Power Point Tracking (MPPT) technology with 99% tracking efficiency and 98% peak conversion efficiency. It automatically recognizes 12V/24V/36V/48V systems for non-lithium batteries (24V lithium batteries require manual setting) and supports a wide range of battery types, including LiFePO4, AGM, GEL, and flooded batteries. Equipped with an external temperature sensor, it precisely monitors battery temperature (operating range: -40°F to 149°F) to prevent undercharging in cold climates and overcharging in hot weather. The durable die-cast aluminium heat sink ensures efficient heat dissipation, while insulated casing and 8 built-in electronic protections safeguard against voltage fluctuations, short circuits, and electrical hazards. Bluetooth-ready (compatible with the optional BT-1 module), it enables real-time remote monitoring via the Renogy ONE portal, allowing you to track system performance and customize charging parameters from anywhere. With versatile load control modes (Auto-On/Off, Timer, Manual, Test, Always-On) and expandable system capacity, it’s ideal for residential, RV, marine, and outdoor solar setups. Key Features: Ultra-High Efficiency: 99% MPPT tracking efficiency and 98% peak conversion efficiency, harvesting 30% more power than PWM controllers. Multi-Voltage Compatibility: Auto-detects 12V/24V/36V/48V systems (non-lithium batteries); supports lithium batteries (24V LiFePO4 requires manual setting). Precision Temperature Compensation: Included external sensor monitors battery temperature (-40°F to 149°F) to optimize charging and prevent damage. Comprehensive Safety Protections: 8 electronic protections (voltage/current/load monitoring) + insulated casing + IP32 enclosure for reliable, hazard-free operation. Efficient Heat Dissipation: Die-cast aluminium heat sink channels heat away, maintaining performance and protecting critical components. Bluetooth-Ready Remote Monitoring: Compatible with optional BT-1 module for real-time tracking and parameter customization via the Renogy ONE portal. Versatile Load Control: 5 operating modes (Auto-On/Off, Timer, Manual, Test, Always-On) maximize system flexibility for various DC loads (lights, fans, etc.). Expandable System Capacity: Supports up to 800W (12V), 1600W (24V), 2400W (36V), or 3200W (48V) PV input power for scalable solar setups.
