Motorhomes

Electrics that travel with you.

Motorhomes combine vehicle and living electrics in tight spaces: road vibration, bathroom humidity, high currents from solar and lithium. We assemble harnesses for body builders and OEMs — from first sample to series.

On-board

12/24V on-board systems

Main and sub-distribution, lighting, pump and heating wiring. Cables per ISO 6722, labeled and tested. Cross-sections 0.35 mm² to 16 mm², fuse concepts per customer layout.

Solar

Solar & energy

DC wiring from roof solar via MPPT to LiFePO₄ battery. High-current lines, correct cross-sections, UV-resistant external routing and shielded data lines for monitoring.

Body

Body & interior

Harnesses for kitchen, bathroom, HVAC and smart home bus (e.g. CAN/LIN). Moisture-rated connectors, flexible routing in furniture and cabinets, modular plug systems for service.

Motorhome requirements

Complete on-board system incl. solar DC for new platform

For a new semi-integrated platform, chassis, interior and solar wiring were to come from one source — instead of three suppliers and manual rework on the line. We delivered modular harness sets with uniform labeling, pre-tested connectors and documented 100% final inspection.
