Tracking Inverter AC Overvoltage Trips

[onestiddca]

Hi everyone,
I’m a brand new user of this very interesting integration — thanks to all the contributors for the great work so far!
I searched through the discussions and couldn’t find a reference to this specific topic, so here’s my proposal (apologies in advance if I’ve missed an existing thread).

Like many others, I’m facing frequent overvoltage protection events on the AC side due to limited grid capacity in my area.
Currently, there’s no straightforward way to tell whether the “holes” or drops in the typical daily power production curve are caused by cloud cover or by real inverter overvoltage protection triggers.
Even while adjusting the derating curve, I was never fully sure about the root cause of those production dips.
So, I started experimenting a bit using the older solaredge-modbus integration and I found that overvoltage interventions correspond to the following register values:
sensor.solaredge_status = 7
sensor.solaredge_status_vendor = 195

To test this, I implemented a simple counter in Home Assistant that increments each time status_vendor equals 195, and resets daily. This gives me a very basic but effective way to track overvoltage events per day, week, etc.
However, I wasn’t able to find an equivalent of the solaredge_status_vendor sensor in the current integration.
In my opinion, this could be an interesting feature to include in the official integration — providing users with a simple way to become aware of possible grid bottlenecks affecting their system’s production performance.
What do you think? Would this be a useful addition?
Thanks in advance for your feedback!

It's in there, all of the entities here will have the inverter ID in the name.

sensor.solaredge_i1_status_vendor
