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 feature.

Previously, coaches operated either on shore power 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.
