Flagship Performance & System Scalability

• Advanced Stacking Capabilities: Increase your power by stacking two units in parallel for double the amperage, or in series to create a 120/240V split-phase system.
• Generator Support Mode: Automatically supplements a generator when AC loads exceed the generator’s capacity, allowing smaller generators to handle large peak loads.
• Ultra-Fast 150A Charger: Dramatically reduces charging time for large AGM, Gel, and flooded battery banks.
• Commercial Grade Surge: Delivers 6000W (200% of rated power) for 5 seconds to provide the high-torque startup needed for compressors and motors.
• Dead Battery Charging: Capable of charging battery banks that have been discharged down to 0 Vdc.
• Xanbus Network Communication: Seamlessly integrates with Xantrex AGS, System Control Panels (SCP), and battery monitors for a fully automated power system.
