RV electrical design made easy
RV electrical systems share many similarities with van builds but often have larger power requirements and shore power hookup capabilities. Whether you’re upgrading an older travel trailer, adding solar to a fifth wheel, or designing the electrical system for a motorhome, No-Sparks validates your wiring for safety.
Typical RV electrical components
- House batteries — 100Ah to 400Ah for boondocking
- Shore power hookup — 30A or 50A connection to campground power
- Converter/charger — converts shore AC to 12V DC for battery charging
- Solar panels — roof-mounted for off-grid camping
- DC fuse panel — distributes power to lights, fans, water pump, and more
- Inverter — powers AC appliances from battery bank
- Battery monitor — tracks state of charge and power consumption
