Goal Zero 30' Extension Cable 8 mm 9 m Or 30 Extra Feet to Connect Solar Panels to Each Other Or Can Be Used to Connect Panels to Yeti Or Sherpa 100ac for Charging

Without this, Goal Zero solar panels and battery must be no more than 6’ apart.

Cable works fine with goal zero products. We are very happy with our goal zero generator and have purchased three more over time.

I was having a little trouble finding ratted watts for the 8mm and HPP cables from goal zero so I decided to do some testing, it turns out the type of cables you use and how long the runs are makes a big difference in power delivered to your Yeti battery pack! Below are the results from my tests, hope this helps!I hooked up two Goal Zero Bolder 100 BC solar panels and one Bolder 50 solar panel for this test these were then combined using the 4x 8mm to HPP combiner from Goal Zero. It is February in Arizona in early afternoon we had good direct sun but since it is winter the sun was not directly overheadAt the panel the watt output was 162 watts which is pretty good for a winter day! I tested the following configurations over about 10-15 minutes to minimize change in suns position. As you can see below how you hook up the panels makes a huge difference, upgrading to an HPP cable could provide you a significant boost in power to your Yeti battery depending on your current setup, may be much cheaper than buying an additional solar panel!Testing with Yeti 1000+4x 8MM to HPP Combiner -162 Watts+ 30’ HPP Cable -161-162 Watts (Basically no loss)+30’ 8mm Cable – 147 Watts (Loss of 15 Watts)+30’ 8mm Cable x 2 (60’ run) -102 Watts (Loss of 60 Watts OUCH!!) Also cables were getting warm+30’ HPP Cable to. 8mm adapter -162 Watts (Basically no loss)+30’ HPP Cable to. 8mm adapter + 30’ 8MM Cable (60’ run) -133 Watts (Loss of 29 Watts)+30’ HPP Cable to. 8mm adapter + 30’ 8MM Cable x2 (90’ run) -91 Watts (Loss of 71 Watts!!!)Testing with Yeti 400+120 Watts - 30’ HPP Cable to. 8mm adapter*These results would be same for Sherpa, or Yeti 200x / Yeti 150 the charge controllers on these units are limited to 120 watt input and will restrict inputs that provide more poser to protect internal componentsConclusion, you might be able to get a significant boost in performance with a simple upgrade to wiring. Since the Yeti 400 limits the 8mm input to 120 watts I’d probably only use the 8mm cables for applications of 120 watts or under, otherwise you are leaving a significant amount of power on the table especially if your have more than one 30’ cable connected together. .The HPP cables are rated for 45 amps, the Yeti solar panels put out between 14-22 watts, this works out to a minimum watt capacity of 630 watts, but beware, longer runs with watt outputs over 300 may have some loss of total output.Hope this helps! Wish Goal Zero would publish some of this information on their website but I did the work for you so you don’t’ have to buy everything to find out-Cheers!

The connecting plugs are pretty solid. The cable is strong, but my concern with this cable, as with all Goal Zero 12 volt cables, is the gauge of the wire and the power losses from the solar panel to the power pack. The cable in this case is not very thick. Goal Zero themselves have said that you can see up to a 1% loss of power PER FOOT of extension cable, meaning that this cable could take up to 30% of the power outputting from your solar panels through transmission loss in the cable.Goal Zero makes PORTABLE solar power solutions, and as such this cable is a compromise between a bulky, heavy, thicker gauge cable that would not lose much power but would be cumbersome to carry, and a lighter cable that is easier to pack in a back pack for example.

I just tested these and they do lose 10% power per cable. If you put 2 together for 60 feet, you will lose 20% power. And also, at 200W-220W they become hot almost instantly (in the shade and cool conditions) so that tells me these would be dangerous to use with panels > 100W. I think these might work well with say a Jackery 500 and a 100W panel (either glass panel or a Jackery 100W foldable panel), but would be terrible to use with a 200W glass panel or with a 200W power brick. Not only will you lose 10%, they will get hot and are so thin I would not be surprised if they shocked you a little bit if you grabbed the wire and were pumping 200+W through them. Be safe and just use these with a 100W panel or Lower. If you need an extension for 200W panel or a Series setup with 2 or more 100W panels or even 2x 200W panels, get a 10AWG red and black MC4 extension cable (they sell those here on Amazon in 20 feet lengths) and it will be safe and you will have no power loss. These are cheap at $24.95 and you get a generous length of 30 feet, so these are not bad for 100W or less applications, and as another user said, since the wire is thinner, it makes it light weight and more portable for backpacking, etc. But if you got 2 or 3 200W glass panels and are charging up a Bluetti eb240 at 330W to 495W or something big like that, these wires will probably catch on fire, melt, and/or shock you (and prior to melting, 10-20% of the power will not make it to the power station anyways).

Was exactly what I needed goo quality.

I use this cord with my Jackery 300 and it’s absolutely perfect! Very sturdy and feels very quality in my hand. And usually when you use a long cord to charge your batteries from Solar you lose a good chunk of power because the cord is so long. But I find that with this cord I only lose about 5W which is hardly noticeable. I highly recommend this product and have nothing negative to say about it!

No dislikes.
