Our tech checking panel output in St. Lucie West before tracking a failed MC4 connection.
What our on-site RV solar repair visit includes
We show up at your site in , from Tradition to St. Lucie West to Spanish Lakes, with a stocked service van. First, we test panel output in full sun, then we meter the controller, check fuses, breakers, MC4s, and combiner, and finally load-test your batteries and inverter. You’ll see readings, not guesses. Ever had three different shops blame three different parts? We’ve seen that too. We don’t shotgun parts.
We carry MC4 connectors, 10 AWG PV wire, ANL fuses, resettable breakers, Dicor for roof penetrations, and common solar controllers. If your Victron, Renogy, or Zamp gear is repairable that day, we’ll do it. If it needs replacement, you’ll get clear options and a written price before we touch it. Most jobs take 60 to 120 minutes.
Common RV solar problems we fix every week
The big three in St. Lucie County are corroded MC4s from salt air, browned roof glands from heat, and undersized wiring starving inverters. Summer thunderstorms, then blazing sun. That cycle cooks weak connections. We also see controllers stuck in float, failed diode bypasses inside panels, and battery management systems tripping on lithium banks.
Last week at a site off Crosstown Parkway, a customer’s panels “looked fine,” but the combiner had a melted fuse holder. Zero output. We replaced the holder with a Blue Sea breaker, remade the MC4s, and saw 19.4 amps at noon. Night and day. Another one at PGA Village had a tired PWM controller that never brought a 200 Ah AGM bank over 13.8 volts. We swapped to a Victron SmartSolar MPPT with Bluetooth. Fixed.
Pricing: diagnostics, repairs, and upgrade packages
Here’s how we price it, straight up. On-site solar diagnostic in is $129. Minor repairs like replacing MC4s, fixing a gland leak, or resetting a tripped breaker usually run $185 to $325 total. Bad controllers or bad inverters push most repair tickets into the $350 to $650 range, parts and labor included. Full rewire and battery upgrades vary by coach.
Upgrade packages we install a lot:
- 400W to 600W panel upgrade with MPPT controller: $1,450 to $2,250. Lithium conversion, 200 Ah to 300 Ah with proper battery heater option: $1,950 to $3,400. Inverter-charger upgrade to a 2,000W or 3,000W pure sine unit: $1,600 to $2,900.
No surprise invoices. You approve everything. Call to get a free estimate or to book same-day mobile RV repair service.
We replaced undersized PV leads and added a Victron MPPT with proper overcurrent protection.
RV solar repair: our step-by-step on-the-roof and in the bay
We follow a repeatable process because guessing wastes your time. First, open-circuit voltage and short-circuit current at the panels. Then we test at the controller to see where the drop lives. If panel readings match spec but controller input is low, the wiring or connectors are the culprit. If controller input is right but battery charging is off, we’re into controller settings or load issues.
We check for shading from AC shrouds or satellite domes, clean panels with a neutral soap, and reseal any suspect roof penetrations. On the electrical side, we verify wire gauge against expected amperage. Too thin, too long, or too many splices, and you lose watts. Sound familiar? We hate spaghetti wiring too. Clean runs. Labeled breakers. Solid crimps with a ratcheting tool, not pliers.
Upgrades that are actually worth it on Florida’s Treasure Coast
Salt air and heat near Hutchinson Island and Jensen Beach mean two things for solar: corrosion and thermal derate. So stainless hardware, UV-rated cable, marine-grade glands, and MPPT controllers with decent heat sinks are worth every penny. Lithium batteries are great here if you camp off-grid often. They hold voltage, charge fast, and don’t sag under inverter loads. But you need a real BMS and correct charge profiles. We prefer Battle Born or Victron Smart LiFePO4 for reliability.
Panels? Go with 100W to 200W framed mono modules from a known brand. No flexible panels on a hot Florida roof. We’ve peeled too many that bubbled or cracked. Honestly, I’d skip off-brand eBay modules. They fail early, then you buy twice. A properly-sized MPPT, short PV runs in 10 AWG, and a clean combiner layout beat a bigger but messy array every single time.
Tidy lithium bank with proper ANL fusing and labeled bus bars for serviceability.
Brands and parts we trust, and a few we don’t
We like Victron Energy controllers and inverters because the Smart app shows real data and makes setup easy. Renogy panels are fine for budget builds if we rework the wiring and protection. Zamp is solid for roof hardware. For batteries, Battle Born has real support, and their drop-in 100 Ah units play nice with Victron. For breakers and fuses, Blue Sea Systems and Bussmann. No off-brand breakers that trip whenever the sun sneezes.
Stuff we’re not fans of: cheap PWM controllers on anything over 200W, flexible panels baking on a fiberglass roof, and “all-in-one” inverter-chargers with mystery firmware. We’ve had those fail at the worst time, like mid-July at Savannas Preserve when the AC needed shore power pass-through. Not fun.
Safety, codes, and doing it right the first time
RV electrical work isn’t house wiring. It’s rolling, vibrating, and sees a ton of heat. We follow NFPA 1192 for RV systems and use guidance from NEC Article 551 for recreational vehicles. According to NFPA 1192, overcurrent protection and conductor routing are not optional, and NEC 551 points you to correct conductor types and overcurrent device placement. We size wire for ampacity and voltage drop, not just minimums. Battery compartments get ventilation and correct clearances.
We also stick with manufacturer specs. Victron’s SmartSolar manual spells out wire sizing and fuse protection. Same with Battle Born’s charge parameters. If a brand doc says set absorption at 14.4 volts, we set 14.4. Period. You’ll get a config sheet in your invoice so the next tech can see exactly how it’s set.

Leak checks and roof work tied to solar
Solar penetrations are common leak points in St. Lucie’s summer storms. We see dried Dicor around cable glands and combiner boxes, then brown stains inside the ceiling panel. We pull the gland, clean the roof, reset with new butyl and lap sealant, and add a UV-rated boot. If the roof membrane is chalking, we’ll recommend a roof inspection. We do full rv roof repair and rv roof leak repair if needed.
A customer near Tradition Town Square called after a thunderstorm. Water found its way through a cracked gland and down the PV wire. We replaced the gland, resealed, then rerouted with a proper drip loop. Took 90 minutes. Cheaper than interior panel repairs, for sure.
Cracked gland replaced, new butyl and lap sealant applied, cables re-terminated.
Power complaints we trace back to non-solar issues
Half of “solar is dead” calls turn into battery or inverter issues. Bad AGMs won’t hold charge, so even perfect panels look weak. Inverters set to wrong AC input or bad transfer relays make it worse. We do full rv electrical repair checks, plus rv generator repair if your genset won’t pick up the slack. If your fridge or AC acts up, we also handle rv refrigerator repair and rv ac repair on the same visit when scheduling allows.
Tip we share a lot: If your controller shows bulk charging all day but voltage never rises, suspect the battery bank. A 5-minute load test tells the story. Big mistake is replacing the controller first. Not even close.
Mobile coverage and response times across the Treasure Coast
We serve all of , with most same-day calls inside and St. Lucie West. Drive times: 10 to 20 minutes across Port St. Lucie, 25 minutes to Fort Pierce, 20 to Jensen Beach, and 35 to Hutchinson Island, depending on US-1 traffic. We’ll meet you at RV resorts, storage lots, and driveways. Snowbirds at Outdoor Resorts and motorhomes near Tradition, we’ve got you.
Storm season gets busy. If you need emergency rv repair after a lightning pop or surge, call https://deanuhlo920.lowescouponn.com/rv-solar-charge-controller-repair-by-a1-rv-repair-port-st-lucie early. We stock common controllers, breakers, and MC4s, but specialty inverters may need 1 to 2 days. We keep you posted, no ghosting.
How to prep your coach before we arrive
- Clear the ladder area and roof access point. Know where your batteries, controller, and inverter sit. If possible, have shore power ready for inverter tests. Jot down symptoms and when they happen.
This simple prep saves 30 to 45 minutes and keeps your bill down. And it helps us find gremlins faster.
Real jobs we’ve done in Port St. Lucie this month
A fifth wheel near St. Lucie West had mismatched 100W panels in parallel with a 200W panel through a PWM controller. Weird combo. We reconfigured to series-parallel into a 50A MPPT, replaced all MC4s, and jumped from 6 amps to 17 amps at noon sun. Another customer at a Jensen Beach campground had a 3,000W inverter wired with 6 AWG on a 12-foot run. Voltage sag under coffee maker load. We upsized to 2/0 with proper lugs and heat shrink. Rock solid now.
We also had a coach by the Savannas Recreational Area with a parasitic draw that killed lithiums overnight. Culprit was a stuck relay in a DC fridge. We added a Victron SmartShunt so the owner can watch draws on the phone. Problem found. Problem solved.
Warranties, licensing, and how we stand behind the work
We’re licensed and insured. You get a 12-month workmanship warranty on our solar wiring and terminations. Manufacturer warranties apply to the parts we install. If a gland we set leaks, we fix it. If a crimp we made loosens, we redo it. Simple. You’ll get photos of roof work and wiring in your invoice so you can see exactly what we did.

FAQ: RV solar repair and upgrades in Port St. Lucie
Q: How much does RV solar repair cost in Port St. Lucie?
A: Most solar repairs land between $185 and $650, depending on parts. Diagnostics are $129 in . A failed controller or bad inverter drives the higher end. Minor fixes like MC4 replacements, new breakers, or resealing glands are on the lower end. You’ll get an upfront quote before any repair.
Q: Can you do same-day mobile RV repair at my campsite?
A: Yes, if we have the parts on the van and your roof is safe to access, we usually finish the same day. We stock controllers, breakers, fuses, MC4s, and PV cable. Specialty inverters or lithium batteries may take 1 to 2 days. Call to grab a slot.
Q: Do I need an MPPT controller for Florida sun?
A: You should. MPPT squeezes more power in heat and partial shade, which we get along the Treasure Coast. On arrays 300W and up, MPPT routinely adds noticeable daily amp-hours. We install Victron SmartSolar because setup and monitoring are clean and reliable.
Q: Are flexible solar panels good for RV roofs?
A: We don’t recommend them here. Our heat and sun cook flexible laminates. They can bubble, crack, and fail early. Framed mono panels with standoffs run cooler, last longer, and are easier to service. We’ve replaced many failed flex panels around Hutchinson Island.
Q: What size inverter do I need to run a coffee maker and microwave?
A: A 2,000W pure sine inverter usually handles a standard coffee maker and mid-size microwave, not at the same time. For dual loads or larger microwaves, go 3,000W. You’ll also need 2/0 or 4/0 battery cabling and proper fusing. We’ll size it during the site visit.
Q: Can you add lithium batteries to my existing solar setup?
A: Yes. We match lithium to your controller and inverter, update charge profiles, and add a battery monitor. 200 Ah to 300 Ah LiFePO4 works great for most boondocking. You’ll get a printed config with voltages and temperature specs that follow Battle Born or Victron guidance.
Q: How long does an RV solar install take?
A: Small upgrades, like swapping a controller and tidying wiring, take 2 to 3 hours. Adding 400W to 600W of panels with a new MPPT and breakers runs 4 to 6 hours. Full lithium and a 3,000W inverter-charger can be a day and a half, depending on coach layout.
Q: Do you handle leaks around solar mounts?
A: Yes. We reseal mounts, replace cracked glands, and correct cable routing. If the roof membrane is failing, we offer full rv roof leak repair and rv roof repair. You’ll see before-and-after photos in your invoice so you know it’s sealed.
Q: What areas do you serve outside Port St. Lucie?
A: We cover , including Fort Pierce, Jensen Beach, Hutchinson Island, and nearby campgrounds. Drive times vary, usually 20 to 40 minutes. We also schedule mobile rv repair for electrical, plumbing, and appliances on the same visit when possible.
