I use a unit from Tripp Lite, an older model called the APS512. I have it attached to a size 29 deep cycle marine battery. It is rated for 500VA continuous and 1000VA surge so it has no problem running my system. I have measured my running current and calculated an 8 to 12 hour run time on battery power.
The Stove Sentry made by Surefire has a website; http://www.stovesentry.com
. Usually these are sold be most pellet stove dealers. They are priced quite high, but they give peace of mind; because of the automatic switchover. You can extend the run time, by merely adding more batteries. If the power is off for a longer time, you could run a pair of wires from your vehicle to recharge the storage battery or batteries.
I wonder what the newer version of the Tripp Lite APS512 is? Does it trickle charge (maintain) the battery or batteries and have automatic switchover?
