    Dud battery, or just not enough sunlight?

    sdnative is correct, the running draw is 5 amps, why is this important, because NONE of the fridge manufacturers that I looked at list this data in the specs. Why does that matter ? Because the use data listed refers to a specific test parameter, in real world you open the fridge more or less...

    Dud battery, or just not enough sunlight?

    Now, the lower priced units with the seacop/danfoss, theres a ton of em, I could believe a 3 or 4 amp draw - thats why IMO the more expensive fridges really pay off in the durability and consumption, I tried an aspenora 42qt, 350 bucks, used it a few years, it did the job but had a finicky low...

    Dud battery, or just not enough sunlight?

    I get it but some would read that as it has a 5 amp continuos draw when running.

    Dud battery, or just not enough sunlight?

    How is the arb 45 using 5 amps ? real world data shows 1.2 amps an hour in normal temps. It might surge to 5 amps momentarily on start up. Are the ARB's using seacop/danfoss motors now ?

    Thats not suprising, that fridge is gonna work the batts a fair bit harder than a more efficient fridge.

    Dud battery, or just not enough sunlight?

    I use a sunforce 8 amp with just idiot lights, I am not a big fan of the fridge control units that the fridges with secop/danfoss comps use, they are junk IMO, ever look inside the compressor/control box , connections are lacking, packaging is suspect and you should check the coil mounting, they...

    Dud battery, or just not enough sunlight?

    FWIW my less expensive fridge with the secop/danfoss comp will sometimes show the E1 code and if I pull the cig. lighter plug and replace it clears and shows 12.5V, I do feel that any connections can be suspect, I have also been trying to get an answer from anyone as to wether the low voltage...

    Dud battery, or just not enough sunlight?

    I would not at all be suprised by a drop to 12.1 at night with that fridge. FWIW I check panels alot and get 18 to 21V , with 200watts your system should recover very quickly in the morning. I would be most suspect of a bad battery.

    Dud battery, or just not enough sunlight?

    I can tell you from personal experience that a 75l with a secop/danfoss comp will kill both batteries with no solar in a day / day and 1/2 depending on conditions, amount opened, shaded, etc. With 75+ watts of solar operating at say 75% with decent sun you should be able to run stand alone...

    Dud battery, or just not enough sunlight?

    What fridge ? Did the solar charge controller show input from solar during this event ? I realize you noticed it at night but the day before had you noticed if solar was working at some capacity ? The drop to 11.5 from 12.5 when running is what my cheap socop/danfoss fridge would show, FWIW, it...
