OK, I want to do a solar-power setup for my FT-817. Ideally, I'd like to have a panel that's small enough to fit in my pack, but large enough to charge the 817 batteries (or maintain a charge on a small motorcycle battery). Problem is, I'm not sure what a power setup consists of. I know "sunlight go in, juice come out," but I'm at a loss as to what bits go in between the panel and the plug - charge controllers, power meters and whatnot. Anybody know of a good resource to learn some of this stuff?
Hello Ray,
You just need a charge controller... Here is what I am going to get:

Thanks, I'm checking that out!
Ray,
For a solar set up in order to go directly to the radio from a panel you need a charge controller to make sure the panel doesn't give the radio more than 14 volts. i skipped the charge controller and instead purchased a Energizer back up battery that has the ability to accept a charge up to 19 volts while metering out 12. So i would go panel - back up battery - radio. This way if the panel gives the battery more then 19 volts it will damage the $80 battery and not the $600 radio.
Here is what i purchased:
Battery - this has an adapter that fits the 817 perfectly

Solar Panel. I got this one becasue it folds and is light.

Powerpole interface:

The solar panel has a female cigarette lighter adapter that comes standard with it. I didn't feel like messing around with cutting cables so i picked up the powerwerx adapter to give me a powerpole to plug into. i ended up cutting in a powerpole connection on the power cord for the battery charger and plug the solar panel into that.
Here is a video i found that i modeled my set up after:
