User reviews

Doesn’t save my inverter serial number

Who wants to be entering their serial number into app everytime they open the app? Needs a password so you would think once entered it would be saved. Useless app

Very poor app

Extremely slow, few features , often connection times out. Feels like the app was made by a high school student who failed comp sci.

Terrible app

Delta have built an app that feels like it is 10 years out of date.

It often freezes up after you sign in. You have to close and reopen the app multiple times to get it to work. The user experience is really frustrating.

It’s really unreliable!

Terrible app

Activation Key Needed

I downloaded this app and it is free.
However, I could not use it because it asks for Activation Key and there are none to be found. Rendering this app useless.
It lists app key but needs an activation key for it to work.
