Goal Zero 8mm to High Power Port 4X Combiner Cable

I needed this to connect an 8 mm panel to hi power. With the 4 inputs, I can connect every little camping panel I have to the house battery

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!

Purchased to combine a couple of solar panels. It works well. I just wish the part cost a little less. A high quality part.

At one time Goal Zero offered a 4x 8mm Combiner to 8mm too attach up to 4 solar panels to a Yeti Li400 but discontinued the product. My only option for connecting two standalone (not chained) Boulder 50s to a Yeti Li400 was to purchase two Goal Zero products (Goal Zero Anderson to 8mm connector and Goal Zero 4x 8mm Combiner to Anderson Connector Cable) at twice the price of the 8mm to 8mm Combiner.Goal Zero Anderson to 8mm connectorby Goal Zero* Input: APP (Anderson Power Pole) see close up image for orientation* Output: 8mm Male* Used with: Yeti & Solar* Product SKU: 98054* Allows goal zero solar panels with Anderson output to charge Yeti or Sherpa with 8mm inputsGoal Zero 4x 8mm Combiner to Anderson Connector Cableby Goal Zero* For use with larger Goal Zero Yeti Portable Power Stations with an APP input* Used to safely combine two or more Goal Zero Solar Panels with 8mm outputs into an array with a single Anderson Power Pole (APP) connector* Input: 8mm (4x) & Output: APP (Anderson Powerpole)* Used with: Yeti & Sola

Too bad they need to charge so much

These don't fit the Boulder 30... The output is recessed and the company isn't making the cords to fit their products, I have to return only through UPS that's 18 miles away, such a hassle, thanks for supporting our USPS. Very disappointed.

Works great if u have an Anderson connector on your solar generatorSo pleased I bought a second oneFor a yeti 1250!

This works perfectly for what it's designed for. I am only giving it 4 stars because although it's what I was recommended to purchase by Goal Zero along with 4x Goal Zero MC4 to 8mm cables in order to utilize 4 standard solar panels, this is a very expensive arrangement, and due to the relatively thin 8mm cables, may not be the most efficient solution. I have since discovered MC4 combiners/splitters, which are far less expensive, and allow a single Anderson Power Pole to MC4 adapter to be used instead - which also means thicker wire all the way from the solar panels to the battery. Unless you are using Goal Zero solar panels (quite expensive and no better quality compared to the competition) with the proprietary 8mm connector, this is not the best tool for the job, and I feel somewhat ripped off for being advised by Goal Zero to use this approach rather than cheaper, industry standard parts that I was not aware of when new to solar power.
