I use my solar setup both rafting and on my snocat in winter. (2) 12v 8 watt panels wired in parallel. Charge controller, (4) 12v 7 amp batteries, and 12vdc to 120vac 300 watt inverter all fit inside ammo can. Inverter also has USB charge port @ 12V. The solar panel cable enters ammo can thru CGB connector (so it is waterproof) and allows full time charging. On the river I can open ammo can and run lots of stuff but in rapids I have to close the top 'cause charge controller and inverter are not waterproof. Did a 21 day GC trip in April and all worked fine.
Here's the setup I put together last off-season and seems to be working pretty well:
The battery is just a generic 18AH SLA like Amazon.com: 12 volt 18 Ah Rechargeable Battery: Home ImprovementHey does that battery come from goal zero? Or is it just a marine batery? What about the cable attached to the solar panel. Is it a goal zero part? Thanks.
