RV Electrical Repair & Solar Installation — Phoenix Mobile Service
12-volt gremlins, dead converters, inverter installs, lithium battery upgrades, and full rooftop solar systems — sized for boondocking in the Arizona sun.
Modern RVs are rolling electrical systems — 12-volt house circuits, shore power, converters, inverters, battery banks, and increasingly, rooftop solar. When any of it misbehaves, the symptoms can be maddening: lights that flicker, outlets that die, a battery that won't hold a charge, or a converter that quietly stopped charging months ago. We troubleshoot the whole system and fix the root cause instead of throwing parts at it.
And when it comes to solar, Arizona is one of the best places on earth to have it. We design and install rooftop panels, charge controllers, inverters, and lithium battery banks sized for exactly how you camp — from topping off at a resort to full off-grid boondocking in the desert. Whether you need a repair or a power upgrade, we handle it on-site.
Chasing Down Electrical Gremlins the Right Way
RV electrical problems have a reputation for being frustrating, and it's earned — but only when they're diagnosed by trial and error. The house system runs on 12V DC while shore and generator power come in as 120V AC, with a converter and often an inverter bridging the two. A single symptom like a dead battery could be the converter, the shore connection, a parasitic draw, a bad battery, or a corroded ground.
We diagnose methodically: testing the converter and charger output, the inverter, the battery bank's health, the shore-power path, and the 12V distribution. Finding the actual root cause means the fix sticks — no more swapping batteries every season to chase a problem that was really a failed converter all along.
RV Solar in the Valley of the Sun
If you're going to invest in RV solar, Arizona is the place to do it — we get more usable sun than almost anywhere in the country. The key is designing the system around how you actually camp. A weekend camper who mostly plugs in at parks needs something very different from a full-timer boondocking off-grid for weeks.
We size panels, charge controllers, inverters, and battery capacity to match your real power use, then install and wire it cleanly. Lithium batteries are usually the heart of a serious system — far more usable capacity, faster charging, and much longer life than lead-acid — and they perform well in our heat when the install accounts for it. The result is quiet, reliable power that lets you camp where the hookups aren't.
