RV Inverter Repair

How much does inverter repair or replacement cost on average?

Diagnosis runs $89 and covers a full load test, wiring inspection, and fault-code pull if the unit has a display. If the inverter is repairable - typically a failed capacitor, blown fuse board, or loose DC connection - repair labor runs $280-$450 depending on parts and access.

If the unit is beyond repair or the cost to fix it approaches replacement value, we quote a swap on the spot. Replacement with parts and labor ranges $520-$1,400 depending on wattage and whether you're staying at the same capacity or stepping up.

A standard 2,000W replacement comes in at $685 all-in. We quote flat-rate by phone after a few questions about your rig, inverter size, and how it's wired, so there are no surprises on the invoice.

Can you fix an inverter the same day I call?

For most inverter jobs in our core service areas, same-day service is realistic - we carry 2000W and 4000W units on the truck, so if diagnosis points to a straight swap, we're not waiting on a parts run. When you call, we'll ask a few quick questions about your inverter's brand, wattage, and whether you have a standalone unit or an inverter-charger combo, because the combo units take longer to wire out and back in.

If the inverter tests dead on arrival and your size is on the truck, the job usually wraps the same visit. Where same-day gets harder is with larger or less common units, or when the fault traces back to wiring, a tripped breaker, or a failed battery bank rather than the inverter itself - those we diagnose first before committing to a timeline.

Will a Progressive Dynamics inverter work in my older Jayco?

Progressive Dynamics inverters are a solid OEM-equivalent fit for most Jayco coaches, including older models going back to the mid-2000s. The mounting footprint is standard, and the wiring harness typically lands in the same location as the factory unit, which keeps the install clean.

What we confirm before showing up is wattage - your rig's load profile determines whether you need a 1,000W, 2,000W, or larger unit - and DC cable gauge, because undersized cable on a high-draw inverter creates a voltage drop problem that shows up as poor performance under load rather than an obvious fault. We've done this install across Jayco, Keystone, and Winnebago coaches ranging from 2006 through 2024, so the variations in those platforms aren't surprises. If your coach has a modified sine wave inverter from the factory and you're stepping up to pure sine wave, we'll also check that your sensitive electronics - CPAP, laptop chargers, newer appliance controls - are compatible before we finalize the spec.

What if I have a 48V lithium battery bank - do I need a different inverter?

Yes, a standard 12V inverter won't work with a 48V lithium bank - the input voltage range simply doesn't match, and forcing it will damage the unit or fail to power anything at all. You need a hybrid inverter/charger designed for 48V systems, and we install both Battle Born and Victron units in that configuration.

Installed cost runs $1,200-$1,400, which is more than a basic inverter swap, but the hybrid units bundle the inverter, charger, and battery management into one box - fewer components, cleaner wiring, and the system charges your bank from shore power or a generator automatically. If your existing wiring was sized for a 12V setup, we'll check conductor gauge and fusing before commissioning the new unit, since 48V systems draw lower current but the wiring still needs to match the inverter's spec sheet.

Is inverter repair covered under my RV warranty?

Warranty coverage on an inverter depends on two things: how old your rig is and what your specific policy covers. Most factory warranties run 3-5 years and often exclude electronics or limit inverter coverage to manufacturer defects only, so a failure caused by a wiring surge or corroded connection may not qualify.

Check your dealer paperwork carefully - look for sections on electrical components or "house systems." If your factory coverage has lapsed, any inverter parts we install carry a 5-year A1 warranty. When both coverages overlap, we help you sort out which claim applies to which portion of the repair so you're not paying out of pocket for something that should be covered.

Do you come to my campground or do I need to go to a shop?

We come to you - that's the only way we work. A1 RV Repair is mobile-only, meaning there's no shop to drop your rig off at.

We carry the diagnostic equipment and common inverter parts on the truck, so campgrounds, driveways, storage lots, and most remote sites are all workable locations. In Florida's Treasure Coast and Idaho's Treasure Valley we handle most inverter calls the same day.

Outside those regions, we dispatch through our nationwide certified-tech partner network, so you're still getting a qualified tech at your site rather than towing anywhere. As long as we can park the truck and access your rig's electrical bay, we can work there.

What brands of inverters do you stock and install?

We keep Progressive Dynamics, WFCO, and Battle Born units on the truck for the most common installs, and we can source Victron, Magnum, or a custom-spec unit if your system calls for something specific. Which brand makes sense depends on your battery bank type, your load demands, and whether your rig runs an RV-C network that requires a protocol-compatible inverter - swapping in the wrong unit can leave your control panel unable to read inverter status or manage charging.

Every unit we install is new and OEM-equivalent, and all carry a 5-year parts warranty. If you're upgrading from a modified-sine unit to a pure-sine inverter, we'll also check your transfer switch and shore-power wiring while we're in there, since undersized wiring is the most common reason a new inverter underperforms right out of the box.

Do you service RVs in my area or do I need to call a dealer?

Tell us your location and we'll give you a straight answer on coverage and timing. We run direct mobile service in our covered metros, and outside those areas we dispatch through a nationwide certified-tech partner network - so you're not getting routed to a dealership service department with a weeks-long backlog and a markup on every part.

Many of our techs hold RVIA and RVDA certifications, and the rest bring years of hands-on RV repair experience. For inverter work specifically, that matters - diagnosing a failed inverter versus a wiring fault versus a battery issue that's starving the inverter requires someone who's worked through all three scenarios before, not a general shop tech guessing at it.
