I can't remember the last outage in the 15+ years that I've been here.<BR/><BR/>So, like you, I've made no especial effort to have my system automatically switch to battery (and a lower LVD threshold) when/if the grid fails.<BR/><BR/>Maybe when I do my rejig for the Lithium battery set I'll do exactly that: a simple detection that the grid is on, and in its absence move the LVD threshold down.<BR/><BR/>Rgds<BR/><BR/>DamonUnknownhttps://www.blogger.com/profile/08642207670550763486noreply@blogger.com
