    I put the Inverter to the Test Today.

    Aims 1250 Watt 12V Pure Sine Wave Inverter Charger PICOGLF12W12V120AL

    Temps: 19f Start and 31F End

    Harmon XXV Set to Manual
    Distribution Fan set to Medium

    6am - 12:50 voltage - Note: Under Load when taken
    7am - 12:50
    8am - 12:20
    9am - 12:13
    10am - 11:75
    10:30 - 11:67
    11am - 11:56
    11:45 - 10:50 - Getting close to end of test
    11:56 - 10:21 - ALARM and still running.

    I ended the test when the Alarm from Inverter started. It would have shutoff soon anyway.

    Got I got 6 Real World Hours of running with the Auger feeding pretty steady. I set the stove to 75f and it never shutdown. Lower Temps with power outage and I think it will do 8 hours.

    I have 2 smaller batteries. One for Generator (35ah) and one off RRSC3 (don't really know or care). Both would get me another 4 hours or enough time to charge the 100ah battery.

    I will be buying 2200W Inverter Generator for this stove for "Just in Case" 2008 comes around again (Over 8ft of snow and power outages).

    Hope this helps anyone thinking of going Inverter/Battery for Backup

    Wonder what the run time would be if it were cycling on and off more. The igniter is the biggest draw, when it's running. Seems like the fans and auger going steady may give you more run time than if the igniter is brought into play several times an hour. If that's so, then in an outage it could make most sense to spike the thermostat. This is just guessing though.

    Running in Auto would triple the power use for that time. I bet it would reduce it by 2 hours. Ie only get 4 hours on 100ah battery. I was hoping for 8 hours. Math says 8+ hours. Real World says 6. I did not want to run the battery down anymore. It's still charging. Only have charger doing 20% rate. Normal rate is 35Ah. Just in case I put smaller battery on it and forget to turn it down. It was good test today of Inverter and Battery. Hope I never have to use it. Had 7kw Generator and have yet to use it. Longest power outage has been 4 hours. Had Wood stove then.
