Ok Lithium gurus

Looking forward to seeing your new dream come true. Congrats and enjoy every minute!

On the SilverLeaf control panel one can set the AGS based on % SOC vs voltage (voltage doesn't work for Lithium you must go by SOC). You are able to specify the battery type in the configuration screens, which then leverages SOC instead. I would assume ATC config screen(s) would allow for similar, no?

Best,

The other part of the equation you didn't get answered is longevity of certain battery amp hours. A 13500 btu AC unit draw about 13 amps while running. There is a burst at startup. Based on the running amps, and knowing that there is some losses due to system inefficiencies, you can divide your battery AH by the running amps and multiply by 80 to 90% to get the hours you can run. Figure 100% SOC down to whatever SOC you want to stop pulling from the battery. 930/13=71.5x85%=60.8 hours. This is a rough estimate as it won't run steady and it is hard to calculate the toll the startup draw will take on the battery depending how many times is starts. Plus I didn't take any capacity out for stopping the drain at 10 or 20% SOC.

And you didn't take into account the added amp draw to get the proper wattage at a lower voltage as the battery level drops.
