The app does open up more control options for the Helios 3600. Our unit was turning AC power off to our refrigerator, as it turns out it was doing it when it didn't sense a load for several hours. Was able to fix that through the app by setting a longer time limit. Four stars because it takes several minutes to recognize and status the attached aux batteries.

Accurate and easy but needs the following features. The graphs need adjustable scales, and scale visible on the side of them. My solar only reaches 100W but I can't see the difference on my phone between 100W and 10W! I'd also like an option to only charge up to a certain percent for when I leave solar connected but don't want the battery maxed out. I'd like to know why AC charging cut out at 95% and used solar only, must be trickle charge but a notification to say now trickle charging useful

Device disconnected. It only connects via BT. When you try to connect to WiFi it says "Successful" but still disconnected. Please fix that, it's important feature!
