Frequently Asked Questions
What makes the Marine version different from the standard Freedom XC PRO?
The Marine version includes a built-in NMEA 2000 port for direct integration with marine electronics networks, marine-specific certifications (UL458 Marine Supplement and ABYC compliance), and enhanced corrosion resistance for marine environments.
Can this inverter charge lithium-ion batteries?
Yes, the Freedom XC PRO Marine includes configurable charging profiles specifically designed for lithium-ion batteries, with programmable voltage and current settings to match manufacturer specifications.
What size battery bank is recommended for the 3000W model?
For optimal performance, a minimum 400Ah battery bank is recommended at 12V. Larger battery banks provide longer runtime and reduce discharge stress on the batteries.
Does this unit require professional installation?
Professional installation is highly recommended to ensure proper compliance with ABYC standards, USCG regulations, and manufacturer warranty requirements. Proper DC and AC wiring, grounding, and NMEA 2000 network integration require marine electrical expertise.
How does the automatic transfer switch work?
The built-in 50A transfer relay automatically detects when shore power or generator AC is present and seamlessly transfers loads from inverter power to the external AC source. The switch time is fast enough to prevent interruption of most electronics.
What is the power share feature?
Power share intelligently manages the total AC input current by reducing battery charge current when AC loads are high, preventing shore power breaker trips while maintaining power to critical systems.
