I can’t remember where it is exactly, but somewhere in settings there is an auto function which will automatically lower and raise the volume according to changing speeds.
I’ve had this happen to me as well. In addition, there was another light (can’t recall what it is right now) that would also brighten and dim along with it. I could not discover why it was doing this.
It’s believed that the modem continues to communicate over the Internet. There may be some other things going on in the background as well, but I’m not sure of.
Well, one of the things that is so good about the hybrid, is that as the battery gets low the engine will cycle back on to charge it, then shut down once it’s charged. I love the 5500 W inverter. It powers a 3000 W portable air conditioner with no problems. Does not get hot or anything in the least.
I have read posts on here, where guys have run inverters for up to 24 hours, with no problems. I do not believe that they had to do anything to the software. I just got myself a 5500 W inverter. I ran an air conditioner off of it with no problems. Hope this helps!
