I have one, still haven't used it. I currently have a GZ 30 watt panel to attach it to.
Has anyone attached this to their rig to keep a 12V battery charged up?
How did it work for you? Recommend it or not worthwhile?
Thank you!

Im currently using a Guardian 12 connected to 4 Boulder15's as a test run to keep my ArkPak charged with my ARB fridge pulling power from the ArkPak. So far its been running fine for 6 days with the panels just propped on the window of my living room. the one thing to keep in mind when using the Guardian12 is that it has a max input of 90W so 6 Builder15's is max for it. Ohh also its a PWD ( i think thats what it was called ) not a MTTP controller not sure how much that matters for a smaller setup up to 90W
I've got the exact same setup except I've only got two Boulder 15's. I've got my panels on the roof of my truck hooked up to the Guardian then connected to my Arkpak while my Dometic CF-50 runs off it it keeping my drinks cold @ 32 degrees in the truck.
I picked up the boulders on Black Friday when they were selling them for 35 each. In hindsight I wish would have gotten two more but oh well, didn't have the extra to buy more toys for myself around the holidays..
Curious about what info you found out. Where did you find output voltage specs on the guardian?I did some research on the output voltage vs my battery max voltage for charging and found it to be incompatible. For the occasional charge it might not have made a difference but I decided to ditch the older Guardian since it was not compatible. Which was a bummer because I liked being portable and not having the unit tied to a vehicle. Great to lend it out to friends.
