Goal Zero 4x HPP to 1x HPP+ Solar Series Combiner – 12 AWG, 20A

I used this to combine four 100W panels and it works flawlessly. The 12 AWG wire is heavy duty and the connectors are solid. Installation was simple. My Yeti charges much faster now.

This combiner feels well made. The wires are thick and the connectors are snug. I like that it's rated for 20A so I know it's safe. Works as advertised.

I got this at half off so it was a good deal. It does what it's supposed to and allowed me to daisy-chain my panels. The cables are a little short for my setup, but that's my own planning issue.

If you have multiple HPP panels, this is essential. Simple plug-and-play. I went from two to four panels and my charging time dropped significantly. Highly recommend for any Goal Zero setup.

I've been using this for a couple of months now, and it's been reliable. The connectors are weather-resistant and the wiring is quality. I've had no issues with overheating or voltage drop.

The product works fine, but there were no instructions. I had to look up online how to connect everything. If you're not tech-savvy, you might struggle. Also, the price is high unless on sale.

Works as expected.

I was able to combine my panels easily, but I had to buy extra extension cables because this was too short. Make sure you measure beforehand. Otherwise, it's a quality item.

I upgraded my solar array and needed a way to merge my panels. This combiner did the trick. The 12 AWG wiring carries current well, and the whole thing feels rugged enough for outdoor use. Very satisfied.
