Product Description

The New SF 512 interfaces between a heating appliance (wood pellet or alternative fuel stove) and its AC wall outlet. When AC utility power is present, the SF 512 charges a battery and monitors the wall outlet to detect a power outage. At the moment utility power fails, the SF 512 draws energy from a battery and converts it to enable appliance operation. When utility power returns, the SF 512 automatically switches the appliance back to AC wall outlet power. At the same time, the SF 512 resumes charging 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 a sufficient reserve of battery capacity to enable the pellet stove to operate for the desired time period. Consult the Surefire Stove Sentry operating manual for data relating to the size and number of batteries needed.

    How to Calculate Backup Operating Time

    Determining operating time requires the following inputs:

    a) The size of the battery bank

        i.e. its total Ampere-Hour (A-hr) capacity

    Ampere-Hour capacity is calculated by adding the A-hr ratings

    of all of the batteries in the battery bank where the batteries are

    connected in parallel.

    (For Parallel Connection See Fig. #1)

    b) The current draw for the sentry in Amps (C).

    This can be computed by summing all of the electrical loads

    which the sentry is expected to operate

    c) The average operating duty cycle of the system

    The duty cycle of a system is the ratio of its "on" time

    e.g. if a water circulation pump will work for one minute and is

    then off for two minutes, its duty cycle is calculated as follows:

    d) Once (a) (b) and (c) are known the operating time of

    the sentry (in hours) can be calculated by the formula:

    e.g. for a system with 3 batteries each rated 90 A-hr.

    1) 3 batteries each rated 90 A-hr., A-hr = 3 x 90

    2) A load that draws 4 Amps, C=4

    3) Duty cycle which operates 1 minute "on" followed

               by 3 minutes "off", D = 1/(1+3) = 0.25

              T (Hours)= (3 x 90)/(4 x 10 x 0.25) = 27

     

    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.
