Xantrex Freedom HFS Inverter/Chargers

Another affordable solution from Xantrex. The Freedom HFS Inverter/Charger has everything the Freedom Xi Inverters have, as well as a 55A multi-stage battery charger built in. It will charge a dead battery from zero volts! The programmable smart battery management maximizes system performance, by conserving power, while always making sure the batteries are fully charged. This is a great power management device for anyone using a 12V system. Additionally, the charge rate is configurable from 5A to 55A, so you can set the battery charger for a lower max current if you have a smaller battery bank. It is pre-set for use with lead acid battery technology - flooded, AGM, or Gel - but also has a custom battery setting for use w/LIon battery systems or other specialty batteries with unique charging parameters.


  • Available in 2 models: 1000 watts or 2000 watts true sinewave output
  • Powerful fast charging 55 amp, 12 Vdc multi-stage battery charger
  • Internal automatic transfer switch transitions power from an AC source (ie. shore power) to DC source (ie. battery storage) within a fraction of a second. And then switches back when AC power is detected stable again.
  • Detachable display panel displays inverter status and battery status information on the screen. The panel can be removed and mounted on a wall or other location for easier access and system monitoring.
  • Two GFCI receptacles on the front, during inverter mode, provide 1000 watts or 2000 watts of power to operate AC devices (ie. Generator)
  • High (2X) surge capability allows you to handle hard-to-start loads, such as TVs and refrigerators
  • Cold temperature performance down to - 20°C for the harsh winter environments
  • Quality, reliability and safety measures meet stringent CSA and UL458 with marine supplement standard
  • Configurable ignition control that helps to minimize battery drain. Ignition lockout stops the inverter from operating in the absence of a voltage signal, from the vehicle's ignition. And then the auto-on simply turns the inverter on and off when the ignition is engaged/disengaged.
  • Dead battery charging down to 0 Vdc
  • Quick connect AC terminal block for fast and reliable installation
  • Programmable Smart Battery Management logic to facilitate extended battery use & life
  • Overload, over temperature, under/over voltage protection
  • 2 Year Warranty
  • Tips on location of the Freedom HFS Inverter/Charger:

  • Dry: Do not mount the Freedom HFS in an area subject to splashing water or bilge water
  • Cool: A cooler temperature is better, ideally between 32°F and 104°F
  • Ventilated: For ideal air flow, allow at least 5 inches of clearance at the DC end of the inverter, 1 inch on each side, and 2 inches on the AC end
  • Safe area: Do not install in the same compartment as batteries, or where the gasoline containers are - harmful gases and acid is not good for the inverter
  • Good proximity: To the battery compartment and the AC source, to avoid excessive cable lengths (which reduce input and output power due to wire resistance)

    Bad Transfer Switch


    This inverter is used as a grid tie back up for a solar thermal pump. Our rural electric coop has occasional power interruptions which the inverter works well to switch to battery power. The problem lies in the fact that it doesn't always switch back to grid power and then drains the battery ...
