Electrical, Battery & Solar Repair
Troubleshooting the complete RV power system—from shore power and charging to batteries, inverters, solar, and controls.
An RV electrical problem rarely lives in one box. Shore power, batteries, converters, chargers, inverters, solar controllers, transfer equipment, distribution panels, grounds, disconnects, and digital controls all influence what the owner sees at the outlet or control panel. On The Road RV Tech diagnoses both 12-volt DC and 120-volt AC systems with an emphasis on measurements, system behavior, and equipment compatibility.
12-Volt and 120-Volt
Power Diagnostics
A no-power complaint can begin on either side of the RV electrical system. We look at the power source, distribution path, protection devices, grounds, disconnects, and the loads that are not operating correctly. The purpose is to find where voltage or current stops behaving as expected and whether the cause is upstream, downstream, or related to the equipment itself.

Battery Condition, Charging, and Parasitic Draw
A battery that goes dead does not automatically mean the battery has failed. Charging voltage, configuration, balance, storage loads, disconnects, converter behavior, inverter standby draw, and other parasitic loads can all contribute. Testing the battery bank together with the charging system gives a clearer answer than testing one component in isolation.

Converters, Inverters,
and Transfer Equipment
Converters and inverter/chargers sit at the center of many modern RV power systems. Problems can show up as weak charging, dead batteries, lost outlets, transfer failures, nuisance shutdowns, or inconsistent power when changing sources. Diagnosis includes confirming input power, output behavior, control settings, wiring, and the way the equipment interacts with the rest of the coach.

Solar Controllers, MPPT Systems, and Roof Wiring
Solar charging problems can originate at the panels, roof wiring, connectors, controller, battery bank, configuration, or monitoring equipment. We verify the path from solar input to battery charging and look for conditions such as poor connections, damaged wiring, incorrect settings, or a controller that is not operating as expected.

Victron, Renogy, and Lithium Power Systems
Advanced power systems often combine lithium batteries, inverter/chargers, solar, monitors, shunts, communications, and programmable charging profiles. On The Road RV Tech has confirmed Victron and Renogy installer credentials and works with lithium-focused RV electrical systems. The service can include diagnostics, configuration review, installation planning, and system improvements where appropriate.

Common Reasons For Electrical Service
House batteries will not stay charged
12-volt lights or controls are weak or intermittent
Outlets work on one power source but not another
Inverter alarms or shuts down
Solar production is lower than expected
Battery monitor readings do not make sense
What to Include With Your Service Request
If the RV has no power, weak charging, battery problems, inverter alarms, or inconsistent solar output, send the equipment information and exact symptoms with photos of the battery bank, inverter, controller, and any displayed error codes.
Submit the RV information, current location, symptoms, error codes, prior repair details, and photos when available so the request can be reviewed before the next step.
