SolarFlow 4000 Mix Pro

I’ve watched my meter spin backward every sunny afternoon since plugging it in—the battery holds what the panels generate and kicks in right after sunset, which is exactly what I needed. It’s silent, doesn’t take up much wall space, and the app shows me live charge levels without any fuss. Honestly,

Setup took me under ten minutes, and the app walked me through every step clearly. I’ve already shaved about 30% off my evening grid draw since plugging it in two weeks ago.

Honestly surprised how quiet it runs — I barely notice it’s there, and the app shows exactly what’s stored. The plug-and-play setup meant no electrician, just one afternoon and it’s already cutting my grid draw. Perfect for anyone starting with solar but not ready for a full install.
