I am a newbie poster to the site. I’ve tried to scan old discussions to see what seems to be a pretty simple problem. I have a new 2020 4 Wheel Camper Hawk shell on our not new 2006 Toyota tundra. We have 2, 6V AGM batteries inside the shell - installed by FWC. The shell has a zamp labeled exterior port on both rear and roof which appears to be an SAE plug. I have a portable Zamp 200w solar panel with a charge controller included. Seems like a simple ‘plug and play’ and when I asked Zamp technical support they said plug it in and it should work If the solar panel brand and the port are both Zamp products. I did so and of course I get the ‘bO1’ read out on the charge controller - which indicates it’s not reading a battery. Ditto no go with the Zamp labeled port on the roof. Zamp tech support suggested I connect the panel included alligator clips to the AGM batteries in the hawk shell. Bingo! - charge controller reads the connection (6v)! I did rudimentary inspection and appears that the battery does have a wire that goes to the external ports but can’t see much more. However I have not tested with a voltage meter if these plugs are live and wherein the polarity lies. Guess I need to get one of those?
I see that (unnamed massive online retailer) sells some ‘reverse polarity’ SAE plugs. Is this A waste of time or a simple fix?
Thinking about upgrading the AGM batteries to lithium as I have experimentEd in the past with building a battery box with some great success to power our portable dometic fridge. Any recommendations for a reputable RV solar installer in the Portland, Oregon area?
As y’all can tell by my post, my electrical knowledge is the same as my ability to write succinct online posts - very limited!
any suggestions much appreciated. I feel like I just opened the door to an amazing resource.
