RV Electrical Service in Hobe Sound, FL
From dead batteries to full panel rewires, we diagnose and fix every electrical system in your RV. Mobile service at your location across Martin and Palm Beach counties.
RV electrical problems don't give you much warning. One day the lights work fine, and the next morning your batteries are dead, your converter is clicking, and nothing on the 12V side powers up. In Florida's heat, a dead electrical system means no AC, no fridge, and no way to stay comfortable. That's why we treat every electrical call as urgent.

At RV Repair Hobe Sound, Jake Merritt has been tracing electrical faults in RVs for over 11 years. That's thousands of rigs, from 1990s Class C Winnebagos with corroded fuse panels to brand-new Airstreams with Multiplex wiring systems. We've seen it all, and more importantly, we've fixed it all. Our service truck carries multimeters, clamp meters, wire strippers, heat-shrink terminals, marine-grade connectors, common breakers, and the most frequently needed converters and inverters.
Here's something most RV owners don't realize: your rig runs on two completely separate electrical systems. The 12V DC side powers your lights, water pump, slides, and control boards. The 120V AC side handles your air conditioner, microwave, outlets, and water heater (in electric mode). When we get a call about "electrical problems," the first thing we do is figure out which system is affected. That alone saves hours of guessing.

DetailsCommon RV Electrical Problems in Florida
Florida's climate creates a unique set of electrical challenges for RV owners. The combination of high humidity, salt air along the coast, and intense summer heat accelerates corrosion on terminals, degrades wire insulation faster than normal, and puts extreme load on your AC circuits.
We see the same problems come through our truck every week. Corroded battery terminals that look fine on the outside but have green buildup underneath. Shore power cords with melted prongs from a bad campground pedestal. Converters that stopped charging because a cooling fan failed in 95-degree heat. And breakers that trip constantly because the owner is trying to run two ACs on a 30-amp hookup.
Last summer, we had three rigs in one week at Jonathan Dickinson State Park with the exact same problem: a blown converter from a power surge during a thunderstorm. None of them had surge protectors. A $250 protector would have saved each of them $800 or more in converter replacement costs.

Why RV Owners in Hobe Sound Trust Us
We've been doing this for 11 years across Martin County. That means we've worked on rigs at every campground, storage yard, and driveway between Jupiter and Stuart. We know the common campground power issues at Jonathan Dickinson State Park. We know which storage lots in Jupiter Farms have power pedestals and which don't. We know that salt air in Hobe Sound corrodes battery terminals twice as fast as inland locations.
Jake Merritt holds current RVIA certification. Every repair follows NEC Article 551 (Recreational Vehicles) and NFPA 1192 standards. We use proper gauge wire rated for the amperage, marine-grade connectors that resist Florida's humidity, and heat-shrink terminals on every connection. According to RVIA's 2025 maintenance guidelines, electrical connections should be inspected annually in coastal climates. We see the results when they aren't.
Have questions about your RV's electrical system? Noticed flickering lights or a converter that hums louder than it used to? Don't wait for it to fail completely. Call 772-758-0499 and we'll talk through it.
RV Electrical Service FAQ
Common questions we hear from RV owners in Hobe Sound and Martin County.
Why does my RV keep tripping the campground breaker?
Usually it's an overloaded circuit. Florida RV owners run AC units, microwaves, and water heaters at the same time, which exceeds 30-amp capacity. We'll check your load balance, inspect the shore power cord and pedestal connection, and identify if it's a demand issue or a wiring fault. Per NEC Article 551, your RV's main breaker should match the pedestal rating.
How much does RV electrical repair cost?
It ranges from $95 for simple fixes like breaker replacements or outlet swaps to $2,800 for full panel rewiring or converter-to-inverter upgrades. Most jobs we see in Hobe Sound fall between $150 and $600. We always quote before starting.
Can you upgrade my RV from 30-amp to 50-amp?
Yes. We handle 30-to-50 amp upgrades including the main breaker panel, shore power cord, transfer switch, and all associated wiring. It's a bigger job that usually takes a full day, but it means you can run dual AC units and more appliances without tripping breakers.
My RV batteries die overnight. What's wrong?
There's likely a parasitic draw somewhere in the 12V system. A small appliance, circuit board, or faulty wire is pulling power even when everything looks off. We use a clamp meter to isolate the circuit and find the draw. In Florida's heat, battery life is also shorter, so we'll test cell health too.
Do you install surge protectors on RVs?
Absolutely. We install both portable and hardwired surge protectors from Progressive Industries, Southwire, and Hughes Autoformers. Campground power in Florida can spike during storms or when the grid is overloaded. A good surge protector saves you from a $3,000 converter replacement.
What's the difference between a converter and inverter?
A converter takes 120V shore power and steps it down to 12V DC to charge your batteries and run 12V systems. An inverter does the opposite, turning 12V battery power into 120V AC so you can run household appliances while off-grid. Many modern RVs have a combination unit that does both.
Can you install LED lighting in my RV?
Yes. LED upgrades are one of our most popular electrical jobs. They draw about 75% less power than incandescent bulbs, which is huge for battery life when you're boondocking. We replace fixtures, dimmer switches, and under-cabinet strips. Most rigs take 2 to 3 hours to convert.
Are your repairs up to code?
Every repair follows NEC Article 551 (Recreational Vehicles) and NFPA 1192 standards. Jake Merritt holds current RVIA certification. We use proper gauge wire, marine-grade connectors, and heat-shrink terminals for every connection. Florida's humidity corrodes cheap connectors fast, so we don't cut corners.
