When I purchased the second solar panel I knew there is an accessory pack that I would have to get for it. It was affordable and seemed that it would be just fine. However Ivy said they upgraded the accessory and because of that it will look different. I didn’t mind as I was told that if I wanted the older model of adapter to just send it back and they can swap it out. When I got the upgraded accessory.
When I got the upgraded accessory connectors. I was even more excited about it because of just being able to connect 2 solar panels I can connect 4. Not that I need 4 panels. And how it connected was even easier. However if you think about it “if” any single connector failed or got damaged of the 4 I would still have 3 other connectors. And I’m all about backups. No regrets here
