I don’t think the Jackery is dummy proof, you still have to wire everything into it somehow, still have to connect it to your solar. I’m not sure if you would need a fuse panel between your Jackery and appliances/lights or not?
I’m still a fan of DIY and being able to customize the setup better. To me it’s just a glorified battery with no real pros compared to a legit setup. What if you only need to replace or upgrade one component of it? What if you want a usb or power plug located somewhere else other than on the Jackery? Maybe there are easy answers/solutions to these questions, but I would want to know them before I made the purchase of the Jackery.
