Its been a while since I’ve been here as things are very hectic at work and also the reason why I couldn’t ask about this earlier.
Some troubling things happening in my setup.
During July and August, almost every night/other night I wake up to multiple grid lost/recovery warning emails. This mostly occurs during the night between 11h00 and 04h00 but other times as well.
As these are ungodly hours, I’ve only been able to investigate 2-3 times when I’m alerted to it early enough but still need to consider that VRM is much delayed at times to refresh.
So those 2-3 times I did manage to get to the DB quick enough, I have found that the grid was not off, yet the MP II shows that it was off and busy inverting.
Mostly off only a few minutes at a time before supposedly recovering, but up to 20 times some nights.
Could this really be an Eskom issue? Or maybe something on the inverter that is not right?
Is there a way to determine this by looking at logged data? Where would I look for this?
