Review on 🔌 JoinWin MFG Upgraded Solar Cable to 8mm Adapter for GZ Products - MC4 Compatible (Blue) by William Anacker

Works with Yeti Goal Zero. I have a Yeti 1250 and 400. I've hooked up 3rd party flexible solar panels and used this MC4 to 8mm adapter and it worked fine. Just don't use an inverter as this is already built into the Yeti. For the Yeti 1250 I connected two 100W panels. There are two ports on the Yeti 1250 and each port can only handle 160W (240W total). I accidentally connected two panels (200W total) and only used one port. I received an error message. At first I thought the adapter wasn't working, but when I connected a 100 watt panel per port everything worked like clockwork. The Yeti 400 only has one port, so I used a 100w panel.
