2017 350 SLX OB Grill and Inverter

[Howard Portugal]

Hi All,

My Kenyon electric grill seems to last between 25 and 30 minutes when I run it off the inverter (no shore power). I have 2 "Group 31" batteries connected in parallel which run the inverter. By what I've read and my back-of-the-napkin calcs, I was expecting about 45 mins to an hour of run time. Any thoughts? Decreasing battery efficiency?

Thanks,

Howard

Did you factor in the 80% efficiency of the typical inverter?

Additionally, There is also Peukert's Law that basically states that as the rate of discharge increases from a given battery, the batteries capacity decreases. An electric grill is going to be a HUGE draw.
