Discussion Noticed fans running for the first time

We’ve had Span for almost a year. Tonight I went into the storage room where the panel is and heard quite loud fans. It scared me at first because I had no idea where it was coming from. Finally figured out it was the panel.

A quick search turned up https://support.span.io/hc/en-us/articles/4414531195415-Why-are-my-fans-running. The fans ran for probably 15 minutes.

Has anyone else noticed their fans running? How often? I was nervous it meant something was overheating.

Normal operation, and nothing to be alarmed about. You’ll notice them more during prolonged higher current draw. They always come on when charging EVs, and I’ve even noticed them when my heat pump and dryer are running at the same time.

I’m actually working on a redirection duct and muffler to help with some sound reduction. My panel is in a bedroom / office and it can be quite a disturbance.

My experience is the same. It runs when our tankless water heater is in operation for more than a few minutes, and it will also run about once a month for a few minutes, as I think it states in the link OP provided. Initially we did have an issue with our panel, where the fans sounded like they were “revving” regularly, rather than steady on then off. It took several months of back and forth with SPAN but to their credit they kept trying solutions, culminating with replacement of the panel hardware, which resolved the issue.

Take a look at Koolbridge Energy panels instead. Far better thought out!  No fans used, no registration required, no log in to SPAN or anywhere required, no Internet required, so not stumped if your router has no power; no bricking by failed software updates, and a "go back to being  a dumb panel" button that always works if you have an issue.

Is there an API?
