There's your first false assumption -- Go back to his second message. His total load is less than 20A. HVAC has been measured at roughly 115VAC/10A, and everything else at ~115VAC/8A. That makes the output results a lot easier to deal with. > - Lead-Acid has an energy density of ~40Wh/KG > - so you need at least a 250KG battery per hour > - at 8 hours you're looking at at least 2000KG alone for the battery (at > least) > > I'd recommend a battery + generator solution.... Again, go back to his second message -- there is absolutely no possibility of being able to install a generator of any kind. -- Brad Knowles <[email protected]> LinkedIn Profile: <http://tinyurl.com/y8kpxu> _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
