Charging Goal Zero with Zamp

Hey all. Using a Goal Zero Yeti 1400 as backup power when I boondock with my AS. I already have a Zamp Solar brief case that I plug in to my Zamp port when the sun doesn't hit my fixed panels. Anyone know of a way to use the Zamp Solar Brief Case to charge a Goal Zero Yeti 1400. The panels use an SAE connector but the Goal Zero doesn't. The Zamp panels also have a built in controller. Could I bypass it and is there an adapter I could use that would be compatible with the Yeti's ports? Thanks in advance for any thoughts you may have to enlighten me!

You might want to read this thread, and ask there IMO:

Pahaska seems knowledgeable on GZ issues IMO.

Good luck,

Peter

You should be able to find it here. it depends what receptacle the GZ has. I believe it's the first one.

Thanks. I didn't know polarity inverters existed. Novice here. I would still need to add a converter to the appropriate port on the Goal Zero and find a way to bypass the converter built into my Zamp panels but now I have one piece of the puzzle.

ZAMP tech told me that I would need to abandon the controller on my ZAMP 140 and feed directly into my Goal Zero 400 since the 400 has it's own controller. Goal Zero tech seemed dubious of that solution. Also, it would void the ZAMP warranty.

I use my RAM 2500's AC outlet to charge my GZ400 while driving.

I also use my 25FB's AC outlet powered by the inverter batteries charged by 500 watts of solar on the roof, when boon docking.

I was hoping to use the ZAMP 140 to power the GZ 400 while dry camping in the 68 Caravel. I'll stick with charging the GZ400 in the RAM while towing the little vintage.

Try it...if there is a problem the Zamp Suitcase Controller will show a fault code and open the circuit.
AMHIK...I did my own fly-by-night suitcase wiring, it bailed me out several times.

I use an 80 watt Zamp panel to recharge a Goal Zero Yeti 400. There's an Anderson port on both sides of the Yeti that bypassed the Yeti's built in controler. Zamp panel automatically shuts off when Yeti is fully charged.

Interesting. That would mean you have an SAE to Anderson adapter. Does it reverse polarity as I understood Zamp’s was switched?

I use an SAE to Anderson pigtail. Just make sure red side on Anderson plug is connected to positive side of the SAE plug and Zamp . One issue with doing this is the input-output gauge on the Yeti does not indicate a charge while the Zamp is charging the Yeti. Zamp controler will indicate it's charging and will stop when Yeti is fully charged. If you check the Anderson terminals with a multimeter it will show the Yeti battery is fully charged.

One other thing I forgot to mention. On the Zamp controler, make sure you set the type of battery you are charging. My Yeti 400 uses an "AGM" while the trailer battery is "WET".
There's a button on the controler to set battery type.

I noticed that you mentioned that your Yeti 400 is an AGM. My 400 Lithium does not have Anderson inputs, only a female 8mm input .

I'm considering purchasing this Anderson to 8mm male adapter. https://www.amazon.com/gp/product/B0...VP3AMH26&psc=1

I already have an adapter with that particular Anderson end mated to an SAE connector with a polarity reverser, to 7pin trailer connector. I use this setup for my ZAMP 400 to 7pin trailer connector on my 68 Caravel.

My only concern is whether this particular 8mm male is compatible with the Yeti female. Does anyone happen to know?

Also, my ZAMP 140 is of the newest generation which auto senses lithium batteries like the one in my 400 Lithium. I'm hoping that this capability will negate the need to bypass the ZAMP's controller.
