Xantrex Freedom 458 20-12 Inverter/Charger - Single Input/Dual Output Product Description
Power Your RV Adventures with Reliable Inverter Technology
Imagine pulling into a remote campsite, firing up your coffee maker, microwave, or even powering sensitive electronics without a hitch. The Xantrex Freedom 458 20-12 inverter/charger makes this a reality for RV enthusiasts, boaters, and off-grid living. This powerhouse delivers a robust 2000 watts of continuous modified sine wave power from a 12-volt DC source, surging up to 6000 watts to handle demanding startup loads like air conditioners or power tools. Its built-in transfer switch seamlessly switches between shore power and inverter mode, ensuring uninterrupted electricity whether you're plugged in or boondocking.
What sets this unit apart is its intelligent design tailored for deep-cycle batteries. The temperature-compensated, three-stage charger—bulk, absorption, and float—optimizes recharging while an equalization stage keeps batteries healthy longer. You'll appreciate the power-sharing feature that balances loads to avoid tripping breakers on limited AC inputs, a common frustration in RVs with 30-amp service.
Key Performance Specs That Deliver Real-World Results
Crafted for efficiency and durability, this inverter/charger boasts 92% peak efficiency, minimizing battery drain during extended use. Dual AC outputs with 20/15-amp circuit breakers provide flexible connectivity—one hardwired and one GFCI duplex for convenience. Input flexibility handles 90-130 VAC, perfect for varying shore power conditions.
- Inverter Output: 2000W continuous / 6000W surge at 120V AC, 60Hz with +/-5% regulation
- Charger Capacity: Up to 100A DC output with customizable profiles for wet, gel, or AGM batteries
- Dimensions: Compact footprint of 13.2 x 11.5 x 7.9 inches, ideal for tight RV bays
- Idle Draw: Ultra-low 0.12A to preserve power when not in use
- Remote Ready: Pairs with Freedom Basic Remote or advanced Link panels for monitoring voltage, amps, and settings
Users often praise its quiet operation and surge-handling prowess, making it a go-to for full-time RVers running fridges, TVs, and chargers simultaneously.
Robust Protection for Peace of Mind On the Road
Safety isn't an afterthought—it's engineered in. Over-voltage, under-voltage, overload, short-circuit, and over-temperature protections safeguard your system. Automatic low-battery shutdown prevents deep discharges that shorten battery life. The included battery temperature sensor fine-tunes charging based on ambient conditions, extending the lifespan of your investment.
In real scenarios, like summer heat in the Southwest deserts, these features prevent overheating and ensure consistent performance. No reverse polarity protection means careful installation, but that's standard for high-amp DC systems—always double-check connections.
Easy Integration and Customization Tips
Mounting is straightforward in most RV setups, with versatile orientation options. Wire it with appropriately sized cables (not included) to match your battery bank's amp-hour capacity—aim for at least 400Ah for optimal runtime. Customize charge profiles via remote for your specific batteries: crank up equalization for flooded cells or dial it back for gels.
For advanced setups, integrate with Link 1000 for real-time dashboards showing state-of-charge, power draw, and historical data. Pro tip: Position the unit in a well-ventilated area to maximize cooling and efficiency during heavy loads.
FAQ
What type of batteries work best with the Xantrex Freedom 458 inverter/charger?
This unit supports deep-cycle batteries like flooded wet cells, gel, AGM, and even lithium with custom settings via remote. Match the profile to your battery type for longest life—AGM shines for vibration-heavy RV travel.
Can it power a microwave or air conditioner in an RV?
Yes, the 6000W surge rating handles microwave startups (around 1500-2000W running) and smaller AC units. For larger rooftop units, pair with a bigger battery bank and monitor runtime closely.
How does the automatic transfer switch work?
When shore or generator power is detected (above 90V), it instantly switches from inverter to AC input within milliseconds—your lights won't flicker. Rated for 30A, it prioritizes incoming power to save batteries.
What's the runtime on a typical RV battery setup?
At 2000W full load, expect 15-30 minutes on a single 100Ah battery—scale up with 400-600Ah banks for hours of use. Efficiency peaks at partial loads, so lighter appliances extend runtime significantly.
Does it have GFCI outlets for safety?
The duplex outlet is GFCI-protected, ideal for damp environments like marine or RV exteriors. The hardwired output requires external breakers per code.
How quiet is the Freedom 458 during operation?
Extremely quiet with internal fans activating only under load or heat. Most users report no noticeable fan noise even at half capacity, unlike cheaper inverters that hum constantly.
Can I use it with solar panels?
Absolutely—connect solar via a charge controller to the battery bank. The inverter/charger's multi-stage charging complements solar input, preventing overcharge while prioritizing AC when available.
WARNING: This product can expose you to chemicals including Diisononyl Phthalate (DINP) which is known to the State of California to cause cancer, and Di-isodecyl Phthalate (DIDP) which is known to the State of California to cause reproductive harm.
With filtered modified sine wave output, Freedom inverter/chargers run virtually anything, from electrical equipment to appliances and electronics in your RV. Temperature controlled multistage charging ensures that your batteries are recharged quickly, and automatic shutdown and other safety features protect your expensive deep-cycle batteries from excessive depletion. For inverter/charger control and basic system monitoring, use the Freedom Basic Remote. For advanced battery monitoring and remote control, Freedom 458 systems can be paired with optional Link instrumentation.
