Converters, inverters, ATS units, shore power inlets, and 12V system diagnostics
Mobile RV Pro provides certified mobile RV electrical repair at your location — driveway, storage facility, or campsite — across Utah and Texas. Background-checked technicians diagnose and repair the entire RV electrical system: 12V house circuits, 120V shore power, converters, inverters, automatic transfer switches (ATS), shore power inlets, GFCI outlets, surge protection, and battery wiring. RV electrical service follows a default two-visit process: a diagnostic visit, then a repair visit, both performed at your location. Common parts including converters, ATS units, shore power inlets, GFCI outlets, and basic wiring are stocked on every Mobile RV Pro truck — most repairs are completed at the diagnostic visit when the customer approves the estimate on-site. Mobile RV Pro schedules most diagnostic appointments within 2–5 business days. Call 833-783-4937 for immediate service.
RV electrical failures fall into two systems — 12V DC (house batteries, lights, water pump, fans) and 120V AC (shore power, outlets, microwave, AC unit). Identifying which system has failed and what symptom is occurring helps the technician arrive with the right replacement parts. Most RV electrical failures trace to one of three components: the converter (12V from shore power), the ATS (switching between shore and generator), or a failed shore power inlet.
Typically a failed converter. The converter takes 120V shore power and produces 12V to charge house batteries and run 12V circuits. When it fails, the RV runs on battery alone until the battery dies. Converter replacement is the most common RV electrical repair

moisture in an outlet box, a failed appliance, or an outdoor outlet exposed to weather. Replacing the GFCI is rarely the fix — diagnostic identifies the actual failure point.
RV electrical failures should not be ignored or DIY-repaired. Improperly wired 120V circuits and incorrectly sized 12V components are fire risks and can void RV insurance and warranty coverage. Mobile RV Pro technicians are background-checked and carry full liability insurance. Repair work follows manufacturer wiring diagrams and applicable NEC standards. For complex installs (lithium battery conversions, large inverter systems, generator transfer switch replacements), Mobile RV Pro performs the work at your location and provides the documentation needed for warranty and insurance.
RV electrical repair costs vary by failure type, component brand, and your location within Mobile RV Pro's Utah and Texas service areas. Mobile RV Pro electrical service follows a default two-visit process — a diagnostic visit, then a repair visit — though common parts including converters, ATS units, GFCI outlets, and shore power inlets are stocked on every truck and many repairs are completed at the diagnostic visit. The ranges below include the $90 service-call fee, parts, and labor at $180/hour. Final pricing may vary by area and access conditions.

| 12V wiring repair (per location) | $300 – $650 | Varies with access and length of run |
| Inverter installation (1,000W – 3,000W) | $1,300 – $3,300 | Pure-sine, sized to load; price includes shunt and remote |
| Inverter repair (existing unit) | $330 – $720 | Diagnostic plus board or fan replacement |
| Generator transfer switch replacement | $650 – $1,050 | Wiring and load-test included |
Pricing varies by location, access conditions, and whether a repair requires upgraded parts to meet current code or to support lithium batteries. Most converter, ATS, and GFCI repairs are completed in 1–2 hours of on-site repair time. Inverter installations and large-system rewires take 3–5 hours.
