I have 3 6000XPs in parallel and I have noticed that when I have low wattage output on one of them that its fans do not run and the temperature readings rise above 100F. It is usually when the inverter is outputting less than 200W and at night. I do not have PV hooked up yet and they are running totally off of battery. I keep the batteries charged with 2 chargeverters and the room they are in is air conditioned to 72 degrees F.
Is it normal for 6000XP fans to not run at low wattage outputs?
