Doorbell dies when plugged in to solar mount

Hi- Just got one of the solar mounts for my video doorbell (version 1). When I plug it in, with the doorbell fully charged, it completely stops working (the doorbell). No lights, nothing. The app says it’s online, but can’t communicate with it, and it doesn’t ring. If I unplug it from the solar mount, it works again. I’ve experimented with resetting it up from scratch, and everything else I can think of. Is this a known issue? Any solutions? Thanks.
