Xantrex 81-2010-12 Freedom 458 marine electronic

SKU CH-Q3FR-3FW1C MPN 81-2010-12

A 2000 W inverter charger with filtered modified sine wave output and temperature-controlled multistage charging for marine use

  • 2000 W inverter power runs appliances and sensitive electronics
  • Filtered modified sine wave output supports a wide range of loads
  • Temperature-controlled multistage charging replenishes batteries quickly
  • Automatic shutdown protects deep-cycle batteries from excessive depletion
  • Optional Link instrumentation adds advanced monitoring and remote control

Marine inverter charger 2000 W

The Xantrex Freedom 458 is a 2000 W inverter charger designed for marine and RV electrical systems. It supplies 120 Vac at 60 Hz from a 12 V DC source using filtered modified sine wave output. The unit combines a high-surge inverter with a temperature-controlled multistage battery charger. It suits owners who need reliable AC power and automated battery management on board.

Replaces separate inverter and charger units

Installing the Freedom 458 consolidates two devices into one, reducing wiring complexity and saving space in tight compartments. The jump is worth it when a vessel currently runs a standalone modified sine wave inverter alongside a basic converter charger. Builders who require pure sine wave output for sensitive medical or audio equipment should look elsewhere.

Handles typical RV and boat loads

The 2000 W continuous rating with high surge capability runs common appliances, tools and electronics found in recreational vehicles. Multistage charging replenishes deep-cycle banks quickly while automatic shutdown protects them from excessive depletion. Optional Link instrumentation adds advanced monitoring for larger battery banks. Systems needing more than 2000 W continuous output will exceed this unit's capacity.

Questions about this item

What DC voltage does the 81-2010-12 require for installation?

The Freedom 458 operates from a 12 V DC battery bank, so the vessel must supply a 12-volt system with cables sized for the 2000 W inverter load.

Which wiring step is most often missed when fitting the 81-2010-12?

Installers frequently forget to run a separate DC grounding conductor from the chassis lug to the common ground point, which the safety shutdown logic requires.

What component will need periodic replacement on the 81-2010-12?

The internal cooling fan is the only moving part; it should be inspected annually and replaced when bearing noise appears.
