RV Electrical Repair & Generator Charging Diagnostics
RV Electrical Problems We Solve
Solar Van Man provides RV electrical repair, diagnostics, and energy-system correction for motorhomes, travel trailers, fifth wheels, truck campers, enclosed trailers, race trailers, concession trailers, and vans throughout the Greater Chicago and Milwaukee areas.
We specialize in the systems that require electrical design knowledge, proper charging logic, safe wiring, correct programming, and clean commissioning.
Common problems we diagnose and repair:
Inverter/charger problems
Lithium battery charging problems
Solar charging failures
DC-DC charging issues
Generator charging and transfer problems
Battery monitor and shunt inaccuracies
Shore power and generator pass-through problems
Battery drain and low-voltage shutdown issues
Victron system faults and programming problems
Poorly labeled or incomplete RV electrical upgrades
Unsafe fusing, undersized wiring, and bad system layout
Botched RV solar, lithium, inverter, and DC-DC installations
Generator Charging & Transfer Diagnostics
Many RV generator problems are really electrical-system problems.
Solar Van Man diagnoses generator-related RV power issues involving inverter/chargers, transfer switches, lithium charging settings, shore/generator charging behavior, pass-through operation, neutral/ground handling, AC distribution, and monitoring/control integration.
If the generator runs but the coach still has charging, transfer, inverter, or power-distribution problems, this is exactly the work we handle.
Botched Install Correction
A large share of RV electrical repair starts after a battery, inverter, solar, or DC-DC upgrade was installed without complete system design.
Solar Van Man inspects, documents, repairs, programs, labels, and commissions RV energy systems so the owner knows what works, what was corrected, and what limitations remain.
We correct incomplete and poorly executed upgrades involving:
- Lithium battery conversions
- Solar panel and MPPT systems
- Tow vehicle charge lines
- Victron Cerbo GX and GX Touch monitoring
- Lynx Distributor and fused distribution layouts
- Inverter/charger installations
- DC-DC charging systems
- Generator charging behavior
- Battery monitors and Smart Shunts
- AC subpanels and transfer integration
Brands and Systems
Solar Van Man designs, installs, repairs, and commissions RV energy systems using professional-grade components and proven electrical practices.
We work heavily with Victron Energy systems and also diagnose many common RV electrical platforms, including inverter/chargers, lithium batteries, MPPT solar controllers, DC-DC chargers, converters, transfer switches, shunts, and battery monitoring systems.
Service Area
Solar Van Man is based in Crystal Lake, Illinois and serves tow vehicle, camper, RV, and trailer owners throughout the Greater Chicago and Milwaukee areas by appointment.
