Solar Powered (Panel + Battery Bank) Totally Powers Off at Sunrise

Lmelamed - did you ever find a viable solution? I am wanting to do the same also.

Yes. I used the 2 following items.

Has anyone said something about using 2 power banks instead of one? If not maybe that would work. Solar panel charges 1st battery bank then the 1st battery bank charges the 2nd one which is powering the camera. Have you tried this at all? Also did you say that for sure the battery bank will keep the camera powered for longer then the 1 day?

Better off to just use a larger battery bank. There is at least some energy lost in every conversion, so daisy chaining battery banks would waste a bit more power.
