The GuardianPlus air-cooled generator is the industry's most cost-efficient pre-packaged
permanently installed, automatic back-up power system. The system is
designed to supply electricity to pre-selected emergency circuits (8,
10 or 12) that supply a home's essential items in the event of a utility
power outage. The unit operates on either natural or LP gas. Installation
has been made easier with the pre-packaged
and pre-wired design.
