Dual Power Controller 50A 5500W Automatic Transfer Switch for Off-Grid Solar Win

Experience seamless energy transition with our cutting-edge power management solution designed for solar and wind systems. This device ensures your battery remains protected while optimizing energy usage.

• Automatic Grid Switching: On cloudy or windless days, the system automatically switches to grid power when battery levels are low, ensuring uninterrupted energy supply.
• Reverse UPS Functionality: The ATS controller intelligently switches to grid power when battery voltage drops below a predefined cut-off point and reverts to battery power once it exceeds the recovery voltage.
• Smart Voltage Detection: Automatically distinguishes between DC 12/24/48V and AC 100-120V 60HZ / 220-240V 50HZ. Users can customize cut-off and recovery voltages based on their specific needs.
• Wide Battery Compatibility: Suitable for various battery types including Sealed, Gel, Lead-acid, and Lithium batteries, as long as they fall within the specified voltage ranges (9-17V for 12V systems; 18-30V for 24V systems; 30-60V for 48V systems).
• High Power Output: Delivers up to 5.5kW (110V) or 11kW (220V) with rapid transfer times—less than 10ms from inverter to public power and under 16ms from public power to inverter.
• Real-Time Monitoring: Equipped with an LCD display that shows real-time battery voltage and the operational status of public power, inverter, and battery.

Note: The controller must be connected to a battery to function properly, as it requires battery power data for accurate operation.
