Next time if it fails, take a snapshot of the log BEFORE you restart it and post it on the sunsynk github repo as a fault
A PR is fairly easy, and you first step to help build something that you & hopefully others can use!. In your case it's a single line to the definitions.py file

If you have power outages in this forum you are doing something wrong!

Best is to look at the log, but it should print an error and wait for 30 seconds before it exits (and the watchdog restarts). Unplug the Pi/restarts your router to test this.

See https://kellerza.github.io/sunsynk/reference/mysensors for the imports, then you probably need
SENSORS += MathSensor((186, 187), "PV power", WATT, factors=(1, 1)) - if this works, feel free to create a PR on the repo

Doh, my fault for trying to digest stuff at ungodly hours of the morning and not following up properly.
Thanks a bunch for the pointer again, let me look into that, makes way more sense to me!

RTFM 😉

I've made  a small update to the Dashboard. The load shedding card shows remaining time based on battery SOC and battery power. You will need to create some template sensors as discussed here and provided in the github repo
