Pellet Stove Battery Backup

Stove Battery Backup - Part# 3-20-512
For Pellet Stove and Coal Stokers
When the power quits, Surefire 512H takes over. The Surefire 512H is designed to backup or replace utility power. When it is used with a common 90 A-hr, deep cycle marine battery, its highly efficient circuitry provides approximately 8 hours of operation from a wood pellet stove or stoker in the absence of electricity. It also works with automatic ignition stoves.
Here is how it works
The Surefire 512H interfaces between a pellet stove or coal stoker and the AC electrical supply. When electricity is present, the Surefire 512H charges a battery and surveys the power line. At the instant that a power failure occurs, the Surefire 512H converts the energy stored in the battery to the AC power. This assures operation of the stove without interruption during the absence of electricity.
When AC utility power is restored, the Surefire 512H reinstates AC utility power as a prime energy source to operate the pellet stove or coal stoker. Simultaneously and automatically the Surefire 512H commences the recharging of the battery, to return it to full capacity in preparation for the next power failure.
At sites where utility power is not present, the user should determine if there is sufficient reserve of battery capacity to enable the pellet stove or coal stoker to operate for the desired time period.
