Hardwired doorbell 3 plus solar charger

Our hardwired doorbell 3 isn’t holding a charge so we bought the solar panel. I’m unsure if I need to wire both the solar panel and bell and wall together or do we need to un-hard wire the bell to use the solar charger?

Hi @Palmer5416. If you have your Doorbell 3 hardwired, you do not need to also connect a Solar Panel. The Doorbell is only capable of receiving a trickle charge from one external power source. This Help Center article here will explain why you may still need to periodically charge your battery when hardwired.

I would take the battery out, inspect it for any debris and fully charge it. Once your battery is fully charged, reinsert it into the Doorbell and make sure it is fully seated. I hope this helps!
