Todd,
Yes on all points. Why back up the whole house? The residence is a remodeled traditional New Mexico adobe and the property is fully landscaped; the original meter and service was moved out to a new location and the home's breaker panel location was on an exterior wall around which concrete was poured for a patio. The home has none of the killer electric loads (cooking, water heating, etc.) to make the whole-house option a poor choice. We too normally separate out essential loads from nonessential, but that isn't an option here. Thus the separation can't serve to alert the customer of an outage. The battery-powered light, or an audible alarm out by the road, were the solutions that I though of, but I was hoping for a more imaginative solution. Incidentally, your comment about an amp-hour meter brings another question: a traditional amp-hour meter, like a TriMetric 2020,doesn't work well in GTWB situations, as the charged parameters are seldom met absent a grid outage, and thus the charge efficiency error can accumulate over time and lead to false readings. What do you use, Todd, or if you use a traditional amp-hour meter, how do you program it to fool it into maintaining accuracy in a system that always sits in float? Allan
