Did you look for errors through the layout page by the method I described a couple posts ago? It seems much more inclusive than any other approach I've tried.CS6P-260P/SE3000 - http://tiny.cc/ed5ozxComment

Yeah, I see the same clipping behavior. You could see on my PVoutput page that when my inverter was knocked offline, DC voltage went high too... I think that is normal behavior in that abnormal condition. The 385 voltage would be high for a 5000A inverter, but maybe HD-Wave is tuned higher.

I sent SolarEdge an email about this on Monday, and just received a response. They suspect the AC voltage fluctuations are due to my POCO. He says:
I did update the inverter's firmware and change its country code in order to widen its voltage tolerances a bit.
Edit: It looks like he changed the country code from USA3 to USA5Last edited by jpoet; 08-30-2017, 04:32 PM.Comment

I had a problem where voltage coming in from the grid was too low and tripped the inverter - although it did throw a code. When I initially contacted SCE they tried to say that higher demand in the area in the afternoon (high temps) was causing the voltage to drop but when I pressed it further there was an actual problem with the local substation that they ended up fixing
So take a look at your incoming voltage (charts > inverter > ac voltage) and see how low it is getting. As I recall around 220 causes problemsComment

Thanks for the insight.Comment

Shouldn't trip until it reaches 264. That's what I was told by SolarEdge support.That's 240 + 10%.Comment

My AC Voltage has been all over the map this week - It was 256 v at 6 am on the 25th

The AC voltage at the inverter is what causes a HV trip. This will be the highest at your location, more
than the PoCo input since your inverter is pushing back. Bruce RoeComment
