A new Solar option for battery powered doorbell

I have a doorbell 2. House is not wired for a doorbell, so am using battery option. The doorbell is under a 6 ft+ portico. I currently have 2 battery packs I alternate, and am swapping about every 2 weeks. A solar option with wire that I can run to remote solar device I can place where it would get sun would be nice. Having to swap batteries so often gets a bit old. (Of course, I guess I could get an electrician to wire house for the doorbell if you think that’s the better option.)

@rollabones ,

Maybe I am misunderstanding when you said, “I could get an electrician to wire the house for the doorbell” , which I think you meant as, wiring your house with a house wall-mounted bell-chime?

If I am not misunderstanding you, what you really just need is a power-source to recharge your battery. You do not need a complete wall-mounted house bell-chime, in order to do that. You can just run two little wires from a low-voltage Transformer to your Ring Video Doorbell 2.

Your model doorbell will “trickle-charge” off any compatible low voltage Transformer (rated at 8-24 Volts AC /40Volts maximum at 50/60Hz), as long as you also add an electrical “Wirewound Resistor” (rated at 25 OHM and 50 Watts).

Then change your setting in the Doorbell “Power Source” from “Battery” to “Hardwired.” All Ring Doorbell are actually Battery-Powered (except the Ring Pro) and the hardwire connection provides a “trickle-charge” only to replenish the battery (the doorbell cannot run off the hardwire). By just using a transformer & resistor, you would not have to worry about charging your battery again.

Instructions with diagrams on how to set up the transformer for a Ring Video Doorbell 2:

One of many choices ($18) for a low voltage 8-24V AC transformer (40V maximum) at 50/60Hz:

The $10 electrical Resistor (beause there is no house chime bell to provide the resistance):

After looking at these links, I think you will find this an easy alternative, and you should not need an electrician (you were already thinking about running a wire anyhow from a solar panel). I hope you find this useful and helpful. :slight_smile:
