DIAGNOSTIC EQUIPMENT GUIDE

The test bench behind RV power service — 12V and 120V diagnostics, converter and inverter/charger testing, battery analyzers and solar-array test equipment.

AUDIENCE: RV SERVICE & ENERGY-INSTALL OPERATIONS8 MIN READLAST UPDATED: 2026-09-20REVIEWED BY FIXFIN EQUIPMENT FINANCE TEAM
Technician testing an RV battery bank and roof-mounted solar system with professional diagnostic equipment in a bright service bay.

The modern RV runs on an energy system: house batteries moving to lithium, solar on the roof, charge controllers and inverter/chargers in the basement, and customers who expect it all to work off-grid. The diagnostic bench behind that system is one of the fastest-growing equipment lines in RV service.

This guide groups the test equipment the power-service line needs, and where it overlaps the electrical bench. Safety note: 120V AC work involves real hazards, and lithium systems deserve qualified technicians — FixFin finances the equipment, and provides no live-wire, bypass or battery-modification guidance.

TWO ELECTRICAL WORLDS

RV power service spans DC and AC systems in one vehicle.

12V DC house systems — batteries, converters, power distribution, DC loads
120V AC shore power — panels, transfer switching, inverter output
The conversion layer between them: converters, inverter/chargers, transfer switches
Control boards and networked systems on slide, awning and leveling circuits

PLANNING NOTES

How shops structure the power bench.

Electrical and battery/solar benches share a workbench — one package covers both
Lithium adoption makes the analyzer line a now purchase, not a later one
Firmware and support status matter most for used analyzers
The RV power bench is distinct from passenger-EV high-voltage service — different equipment worlds
