Introducing the REDARC BCDC Trailer S, the ultimate solution for on-trailer DC charging. The BCDC Trailer S combines a 12A charger and a 40A MPPT solar regulator into a single, compact unit, simplifying battery charging for enclosed trailers. The BCDC Trailer S limits the input to 12A making it applicable for any trailer battery setup while the 40A solar input ensures your batteries remain charged even when your engine is off. The BCDC Trailer S expands REDARC’s range of trailer charging solutions, joining the BCDC Trailer (BCDC1212T) to offer versatile and efficient charging options for all trailer types.
