Hello,
I’v read the docs on solar panel charging; and note that the RShake needs 5.1V to boot.
The MPPT L60 charge controller used in your example has USB output ports, but they’re rated at 5V. I’ve tried using another unit, but again only 5V output, and indeed the RShake won’t boot e.g.

Can anyone recommend a charge controller with USB outputs confirmed at 5.1 V and, say, 3A?
Thanks,
Dave

Rather than worry about the USB port on the charge controller, you will probably have better luck running 12v from the output, or the battery it is charging, to one of these, mounted somewhere close to the RShake.

These work fine. There is a discussion about using these here:
More Updates:
I mentioned before that we had several RS3D. We have needed to fabricate our own power cables to reach installation sites that we intend for these stations to go. These lengths extend from the RS3D’s at 5, 10 and 15 m. We are using a 18 AWG power cable for these runs which we thought would result in minimal power loss. After testing, what I found is using the provided RS power adapter that outputs 5 V DC 3.0 A connected to our own cables, that the a 5 m length run was able to powe…

Thanks for this, and all the details in the linked post. Will try it, and report back.
All the best,
