🧾 Overview
The REDARC BCDC Trailer S is a compact power management solution designed to keep your trailer’s auxiliary battery charged while driving or off-grid. Combining a 12-amp DC-DC vehicle charger, a 40-amp MPPT solar regulator, and a smart battery isolator, this system simplifies trailer power management in one lightweight unit.
The BCDC Trailer S is specifically engineered to connect through a standard 7-way trailer plug and existing tow vehicle wiring, allowing for straightforward installation without running dedicated high-current charging cables. This makes it ideal for trailers where charging current is supplied through the vehicle’s towing harness.
Perfect for travel trailers, horse trailers, enclosed work trailers, mobile service units, and emergency response vehicles, the BCDC Trailer S ensures your trailer batteries stay charged while reducing reliance on shore power or generator charging.
