Retrofit and repair campervan and motorhome electrical systems — onboard power up to 48V, mobile on site in the Pirmasens–Karlsruhe region

Field · 01 — Electrical

Power that
travels.

Installation, expansion and repair of onboard power systems up to 48V. We plan, wire and commission — with components built to last in the field.

Power is the backbone of every build. It has to be right.

Whether a complete energy system in a new build or a retrofit and fault-finding on an existing vehicle — we work cleanly, documented, and with components proven in mobile use.
