I have a very odd issue which has happened maybe 2 or 3 times in the last 4 months, today was the last.
What it looks like is the grid falls away for 0.15-0.3 seconds, when I review the data I can see the current going to zero but not the voltage. See the image below.
I can only assume the system is acting as it should, and that either the dip is just too small/ too quick to be picked up by the Quattro's monitoring, or the voltage sensitivity is set too high. South Africa is known for many things, one of them being an unreliable network, so I wouldn't be surprised if it was a voltage dip.
So I guess first and foremost has anyone else experienced anything similar?
And secondly, is there any way to verify exactly why the system started inverting?/ to what extent did the voltage dip?
