I bought four of these to go with a Yeti 3000 as back-up in case of California power shutdowns. Since I rent my house, this set-up is great and along with a small 700W propane generator will power my fridge and freezer for weeks. As a bonus, I can take the whole thing along with me on camping trips.
I can set-up these panels solo within fifteen minutes and have them connected to my Yeti in a couple of minutes more. 800W of panels were feeding about 500W of power to my Yeti at about 1:30 PM in late October just east of Oakland, California. The stand is of good quality, but I with they'd put rubber feet on them as they kind of sink when used on grass.
The panels seem to be well constructed, but two of them were missing one of two nut and bolt pairs that hold the bracket that closes the panels in place. I contacted Goal Zero support and they've mailed me a couple of replacements. They should be easy for me to install myself.
Easy to setup
Heavy enough to sink into soft earth
Perfect for keeping that refrigerator and some lights going during the northern California power shutdowns.
