A 12 volt, deep cycle marine battery up to 200 amps needs to be purchased separately. These can be found at most auto parts stores.

It has to be a deep cycle battery because the plates on an automotive one will sulfate and rot much faster over time.

Pure Sine Wave Battery Back Up 
For Microprocessor Driven Alternative Heating Appliances

800-1000 Watt Capacity



512 interfaces between a heating appliance (wood pellet or alternative fuel stove) and its AC wall outlet. When AC utility power is present, the backup charges the battery and monitors the wall outlet to detect a power outage. At the moment utility power fails, these backup units draws energy from a battery and converts it to enable appliance operation. When utility power returns, the backup automatically switches the appliance back to AC wall outlet power. At the same time, the backup resumes charging the battery to return it to full capacity in preparation for the next power failure.
