The energy management system, standard on Tiffin Motor Homes’
Allegro Bus and Zephyr for 2010, is billed as a “revolutionary new
concept” for RVs by Precision Circuits Inc., which developed the
Previously, coaches operated either on shorepower or generator. The
new energy management system harnesses additional available power from
the coach’s batteries for a short time and automatically sheds
non-critical loads if power demand increases beyond capacity, according
to a news release from the Red Bay, Ala.-based RV manufacturer.
The all-electric coach option becomes even more attractive for
Allegro Bus and Zephyr models with the advent of the energy management
system. An electric stove top, multiple AC units and electronics can
severely tax the available power on conventional rigs. An added benefit:
Since the all-electric coach does not need or have a propane tank, an
additional storage space is available.
