RV Electrical Systems in the Florida Heat
Your RV's electrical system is the backbone of everything else on board. The lights, the water pump, the refrigerator, the air conditioner, the slides, the leveling jacks. Every one of those depends on clean, reliable power. When something goes wrong electrically, the whole rig can feel like it is shutting down around you.
Here in Sebastian and across Indian River County, the electrical demands on an RV are higher than in most parts of the country. Summer ambient temperatures regularly push past 95 degrees, which means your air conditioning runs harder, your batteries cycle faster, and your converter generates more heat than it was designed for. The salt air that rolls in off the Indian River Lagoon accelerates corrosion on exposed terminals, shore power connections, and any wiring junction that was not properly sealed at the factory.
We handle every layer of the RV electrical system. The 120-volt AC side covers your shore power connection, the breaker panel, your outlets, and the power cord itself. The 12-volt DC side covers your batteries, converter, fuse panel, lighting, water pump, and all the low-voltage controls that keep your slides, jacks, and awning working. If your rig has an inverter, that sits between the two systems, pulling DC power from your batteries and converting it to AC for your outlets when you are not plugged in.
Patrick Lee has been diagnosing and repairing RV electrical problems in Indian River County for over 10 years. He carries a full set of diagnostic tools on the truck, including a Fluke 87V multimeter, a clamp meter for amperage testing, a circuit tracer for chasing wiring faults behind walls, and a shore power analyzer to check campground pedestals before we even plug your rig in. About 80 percent of the electrical repairs we encounter get completed in a single visit because we stock the most common breakers, fuses, outlets, connectors, and wire on the truck.
Every repair we do follows NEC Article 551, which is the National Electrical Code section written specifically for recreational vehicles. That means proper wire gauges, correct breaker ratings, appropriate grounding, and GFCI protection where it is required. Florida's humidity and storm activity make code-compliant work more than a formality. It is the difference between a system that lasts and one that creates a fire hazard.
We work on Class A, Class B, and Class C motorhomes, fifth wheels, travel trailers, toy haulers, and pop-up campers. Whether you are a full-timer parked at Vero Beach Koa or a weekend camper at Sebastian Inlet State Park, we drive to you, diagnose the problem, give you a fixed price, and get it done on site.

How RV Electrical Repair Works
Four steps from your first call to a fully tested electrical system.
Describe the issue
Call or text us with your symptoms. Lights flickering? No shore power? Dead batteries? We ask a few targeted questions so we can arrive prepared with the right parts.
On-site diagnostics
We drive to your RV and test voltage, amperage, and continuity across every suspect circuit using professional-grade meters and circuit tracers.
Quote and approval
Once we identify the fault, we explain what failed and why in plain language. You get a written quote before any repair work begins. No surprises, no pressure.
Repair, test, verify
We complete the repair, load-test under real operating conditions, and verify every circuit meets NEC Article 551 specs before we pack up and leave.
RV Electrical Repair FAQ
Florida heat accelerates three types of electrical failure. Battery sulfation happens faster when ambient temperatures stay above 90 degrees for months at a time, cutting battery lifespan by 30 to 40 percent. Converter cooling fans burn out from running nonstop, which causes the converter itself to overheat and fail. And shore power connections corrode faster in the salt air and humidity along the Indian River County coast. We see all three regularly from May through October.
A 30-amp RV service provides one 120-volt hot leg at 30 amps, giving you about 3,600 watts total. A 50-amp service provides two 120-volt hot legs at 50 amps each, giving you about 12,000 watts total. Most travel trailers and smaller motorhomes use 30-amp. Class A motorhomes and larger fifth wheels with two air conditioners typically need 50-amp. Using the wrong adapter or plug can overload your system and trip breakers or melt connections.
An RV converter takes 120-volt AC shore power and converts it to 12-volt DC to charge your batteries and run your 12-volt lights, fans, and water pump. An inverter does the opposite: it takes 12-volt DC from your batteries and converts it to 120-volt AC so you can run household outlets, microwaves, or TVs when you are not plugged in. Many RVs have both. Some newer units have a combo unit called an inverter-charger that handles both directions.
Campground electrical pedestals are notoriously unreliable. Low voltage, open grounds, open neutrals, and voltage spikes can destroy your converter, air conditioner compressor, and sensitive electronics in seconds. A good surge protector with an EMS (electrical management system) monitors incoming power and disconnects your RV automatically if conditions are unsafe. In Florida, summer thunderstorms cause power surges almost daily. We recommend a hardwired Progressive Industries or Surge Guard unit for every RV.
Lead-acid batteries cost less upfront, typically $100 to $200 each, but you can only use about 50 percent of their capacity before you damage them. They weigh roughly 60 to 70 pounds each and last 2 to 4 years in Florida heat. Lithium (LiFePO4) batteries cost $400 to $1,200 each but offer 100 percent usable capacity, weigh about 30 pounds, and last 8 to 10 years with minimal maintenance. Over a 10-year span, lithium usually costs less per usable amp-hour.
Call a professional if you smell burning plastic or see scorched wiring. If your breakers trip repeatedly even after resetting them. If you have no power at all and a new fuse or breaker reset does not fix it. If your batteries drain overnight for no obvious reason. If you get shocked when touching any metal surface in the RV. And if you are planning any 120-volt modifications, NEC Article 551 requires specific wire gauges, breaker ratings, and grounding methods that are easy to get wrong.
Simple fixes like replacing a blown fuse, a bad outlet, or a corroded connection run $95 to $200. Battery replacement ranges from $150 to $800 depending on whether you go lead-acid or lithium. Converter and inverter repairs fall between $200 and $1,200. Full rewiring of a section or major circuit troubleshooting can run $400 to $900. A complete system overhaul with new batteries, converter, and wiring updates tops out around $2,800. Every job starts with a fixed quote.
Most single-issue electrical repairs take 1 to 3 hours on site. A battery swap is usually under an hour. Converter or inverter replacement runs 2 to 4 hours depending on accessibility. Major wiring projects or full system diagnostics can take a full day. We carry the most common parts on the truck, so about 80 percent of repairs are completed in one visit. If we need to order a specific converter or breaker panel, we will schedule a return trip within 2 to 3 business days.
