SureFire Stove Sentry 512 For Pellet Stoves, Harman and more. Works with Most Alternative Fuel Devices. Supports Full Stove Electrical Capacity. For Wall Mount or Surface Mount Installation. 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. 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 or kerosene heater to operate for the desired time period.

How to Calculate Backup Operating Time. Determining operating time requires the following inputs. A The size of the battery bank. 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. For Parallel Connection See Fig. 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. 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. 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. Outdoor wood boiler maintenance. Video will open in a new window. Using the mobile app?
