Product Details

The Xantrex Freedom EX 4000 is a comprehensive power management solution that combines four critical functions in a single compact unit. This true sine wave inverter delivers 4000W continuous power (8000W surge for 5 seconds) from a 48VDC battery system, making it ideal for mobile applications including RVs, marine vessels, and off-grid installations requiring reliable AC power.

Integrated Power System:

  • 4000W True Sine Wave Inverter: Converts 48VDC battery power to clean 120VAC for sensitive electronics and appliances
  • 80A Battery Charger: High-capacity 48VDC charging system with advanced profiles optimized for lithium-ion batteries
  • 50A Transfer Relay: Automatically switches between shore/generator power and battery power
  • 48VDC to 12VDC Converter: Provides 45A of 12VDC output for auxiliary equipment without separate converters

Advanced Configuration & Scalability:

  • Expandable system supports up to 3 units in parallel or 2 units in series for increased power capacity
  • Highly configurable charging parameters designed specifically for lithium-ion battery chemistry
  • RV-C communication protocol enables seamless integration with third-party multi-function panels and monitoring systems
  • Ignition control feature allows remote on/off switching via 12VDC signal

Performance Specifications:

  • Continuous Output: 4000W at 120VAC
  • Surge Capacity: 8000W for 5 seconds (2X continuous rating)
  • Input Voltage: 48VDC nominal
  • Charger Output: 80A at 48VDC
  • DC Converter: 45A at 12VDC output
  • Transfer Relay: 50A capacity

The Freedom EX 4000 is engineered for demanding mobile and off-grid applications where space is limited but power requirements are substantial. Its hybrid capability allows it to work independently or supplement existing generators for improved fuel efficiency and quieter operation. The true sine wave output ensures compatibility with all AC equipment, from laptops and medical devices to power tools and appliances.
