These covers fit my Energizer 2200 inverter generator perfectly. They've held through some pretty strong desert wind. I highly recommend them. They are very well made.

Works well. Using two of them, for 100-feet, to extend the wire from my solar panel into the house. Minimal voltage drop.

はじめて買い使ったので、他がわかりませんが、すごくよいです！毎日晴れの日発電して、使うの楽しみです。ただすごく重いのでベランダまではこぶのが、ちょっと大変ですが💦電気を使用中すこし音がします。大切にながく使っていきたいと思います！

Using this as part of a small 12V system and it works great with an MPPT charge controller. I'm pulling decent wattage even through a window on cloudy days. Tested it against another 100W panel and the output matched. Feels sturdy, MC4 connectors were tight, and voltage readings are spot on. Only complaint is the caulking around the frame could be cleaner, but that’s more cosmetic than functional. If you're set up for 24V input, this is a great value.
