The Power Guard module is a slick little system that will provide back up power to your Essential Buss in the event of a primary battery failure keeping critical devices (Like your EFIS) running until you can get on the ground. Also, if you like to leave certain instruments on during an engine start you will get under voltage protection to those devices as the Power Guard will notice a dip in voltage and keep the devices powered preventing undesired shut down/restart.
