dickandlois Report post Posted January 21, 2013 The Trace series of Inverters are made by Xantrex. However, they are configured more for residential applications. Some of the Couches that incorporate them into there electrical systems are often referred to as all electric using a larger number of solar panels, shore power and generators to maintain, in some cases larger numbers of Coach Batteries that power the inverter(s). These coaches also have a larger primary12 volt panel or 2 to 3 sub-panels powering a greater number of items. Also, there tends to be a greater number of 110 volt outlets built into the coaches. This is more prevalent in coaches with 50 amp. for shore power and the use of inverters that supply 2-- 120 volt feeds that equal 220 volts as measured across the 2 primary line breakers in the main AC power panel. This is a link to a Trace installation PDF file to look at if you wish. http://www.soligent....cts/22161_3.pdf One thing for sure is that as the market and customers look for more features on and in their Coaches, the level of sophistication in the power system increases.
