P10 Power Plant

I have a P10 power plant that is powering my system shown below. During the night when everything is in standby mode, I get random power spikes where the power jumps about 200-250W, but just for a second. It happens most nights, but only once or twice, but sometimes it doesn’t at all. Powerplay captures these in the history logs which is where I first noticed it. They do also happen during the day during normal listening as well, and I can see it on the P10 local display… Again, only lasting a second. Has anyone else had this observation? I find it particularly interesting that it happens when everything is in stand-by mode. Thanks
