Frustrated setting up app all I get is unknown error

Lots of unclear settings

I got an EG4 backup system installed three years ago, but was never able to get it to work even after two electricians looked at it and countless calls to Signature Solar and hours of waiting on hold didn’t help at all. After giving up for a couple years, I decided to let AI give it a try and finally it was able to figure out the correct settings.

Must Have for EG4 Inverters

App is a must have because it permits online support to install latest firmware for inverter. Also great is monitoring of Inverters in parallel and recording of events, such as error codes.

Good, but can always improve.

From my view this is a good tool to view quickly your system.

Improvements:
1. Make the numbers bigger for incoming wattage from the grid. It is tiny on my phone but voltage is large?
2. Using the drop down I go to gridboss and it shows β€œoffline’, I need to go to the β€˜flow’ button to see the data. Correct the offline when actually online
3. The Home Screen, you are able to make changes too easily, if I have the app open and I stick it in my pocket it may trigger”quick charge” or other settings on accident, when I take out my phone I don’t know the history of what happened. Maybe have a check.. β€œare you sure you want to…”
4. For two inverter systems Default to β€œparallel_a” versus just starting on the first inverter.
5. A page showing totals, grid/solar/for the day/week month.

6. Make the Refresh button larger.


Thanks and keep going.

Very helpful!

This app is very useful, but I think the interface could have larger font for us folks who have poor vision. Otherwise, I’d give it five stars.
