Xantrex RV3012GS Inverter Repair: Expert Solutions & Alternatives

Short Answer

Yes, your 2011 Tiffin Phaeton's Xantrex RV3012GS inverter can likely be repaired or remanufactured, even though Xantrex no longer supports these units. Several specialized companies focus on repairing discontinued RV inverters like yours, which is much more cost-effective than the expensive SW3012 upgrade path with new control panels and Xanbus wiring you're facing. The repair route will save you thousands and keep your existing control panel setup intact.

Understanding the Problem

Your RV3012GS is part of Xantrex's Freedom SW series, which uses Xanbus communication protocol. When Xantrex discontinued support, they stopped providing parts and service, making repairs difficult through official channels. While upgrading to a new SW3012 with Xanbus architecture still involves significant cost - the inverter runs around $1,800-2,200, and if your existing control panels aren't compatible with the newer model revision, you may need a new System Control Panel (SCP) for $400-500 and potentially an Auto Generator Start (AGS) panel for $300-400.

Common failure points in the RV3012GS include the DC input fuses, transformer windings, control board components, and cooling fans. Many of these failures are actually quite repairable with the right expertise and parts availability. The units were built robustly, and the core transformer and power components often remain in excellent condition even when control circuits fail.

What You'll Need

For professional repair, you'll need to remove your inverter and ship it to a specialist repair facility. Most companies require the complete unit including any remote panels you currently have. You'll want to document your current wiring setup with photos before removal, as this helps ensure proper reinstallation. Remove all DC and AC connections, but leave wire labels in place.

Expect repair costs between $400-800 depending on what failed, compared to $3,000+ for the complete Xantrex upgrade path. Typical repair turnaround is 2-3 weeks including shipping. Some companies offer expedited service for additional cost if you need your RV back quickly for planned trips.

You may also want to consider having a spare control board or key components rebuilt simultaneously, as preventive maintenance for a unit this age. This adds cost upfront but prevents future failures during travel.

How to Fix It

Start by contacting Inverter Service Center in Riverside, California, which specializes in older Xantrex and Trace Engineering units. They maintain parts inventory for discontinued models and have extensive experience with the RV3012GS series. Call them at their published number to discuss your specific failure symptoms and get a repair estimate.

Another excellent option is Wholesale Solar's repair division, which handles many RV inverter repairs and has worked extensively with the Freedom series. They often can provide faster turnaround than smaller shops and offer warranties on their repair work.

For removal, disconnect your batteries first, then wait at least 15-30 minutes for internal capacitors to discharge before handling internal components. Carefully remove all AC and DC wiring connections, photographing each step. The RV3012GS typically mounts with four bolts and weighs around 45 pounds. Package it securely in the original box if available, or use plenty of padding in a sturdy shipping container.

When shipping, include a detailed description of the failure symptoms, any error codes displayed, and your contact information. Most repair shops will call with a diagnosis and estimate before proceeding with repairs.

Leave It to the Experts

Professional inverter repair requires specialized test equipment, component-level diagnostic skills, and access to obsolete parts that aren't available to consumers. The high-voltage AC and DC sections of these units present safety risks that make DIY repair inadvisable for most RV owners.

Beyond safety concerns, inverter repair often involves surface-mount components, precision soldering, and calibration procedures that require professional-grade equipment. A botched DIY repair attempt can turn a $500 professional fix into a complete write-off, forcing you into that expensive Xantrex upgrade anyway.

The repair specialists mentioned above have seen hundreds of failed RV3012GS units and can often diagnose problems quickly. They maintain relationships with component suppliers and have developed efficient repair procedures that keep costs reasonable. Most offer 6-12 month warranties on their repair work, giving you confidence in the investment.

Consider the repair route first before committing to the expensive upgrade path. Even if repair isn't possible, you'll only be out the diagnostic fee (typically $100-150) and can then proceed with the SW3012 upgrade knowing you explored all options.
