In response to both Robert and Flick,

I've used a combination of power sources when needing to charge camera batteries, satellite phones, etc. in the bush. I've run solar panels through an inverter and it worked well, But I didn't charge the camera batteries directly from that source. I hauled in two marine batteries and charged them from the solar panels (they take DC fine). From there I charged the camera batteries from the marine via an inverter.

Charge the mains while you are out shooting in the day and there's sun for the charge at your base camp. Charge the camera and other batteries at night from the main batteries when the sun is down.

All our electronics work was also done in Vancouver on 2000-2002 technology. Not sure if things have changed since then. Now I just wind my Bolex.

Worked for my situations, hope it helps.
