I have to try that. Also I haven't AC coupled my GT inverters yet, so every time combined solar sell to grid goes over 15kW, Deyes trip.
My 44kW vertical and bifacial set in Finland.

just be a bit careful not to overstep the bounds.
probably deye support can show you exactly what makes it trip and what you need to adjust

It seems that phase 2 is always high when PV production goes up. Phase one may get moderately high and phase 3 is always close to normal. At the main panel (utility connect) 75m away Eastron meter is always showing close to normal voltage with all three phases.

do have a-sync phase feeding turned on under advanced ?
What do you click to get that overview?

Did not, but do now. When enabled on both, voltage seemed to oscillate, so now only one enabled. Still high voltage readings on ph 2 occasionally. Checked all connections with IR gun and they seem to be fine.
I think two hybrids and two GTs all working parallel without any shared info is just too complicated. Or my settings are off. Way too tired to solve this now. Hopefully I get some free time next weekend, but probably not...
Day is 17 hours long and there is already some green on the field. It seems 280-290kWh is possible on a clear day. 260kWh today.
260kwh that's some serious solar power !
What's your RIO looking like? At that rate should pay for itself in no time

Just press "ON" (or OFF if your inverter is off) in the middle of the screen.

Total cost is around 1,25e/W with 44,1kWp and 118kWh of batteries, no tax reduction or anything like that. I guess 5 years if energy rates stay high. ATM I can't sell overproduction to grid as my utility company hasn't installed bidirectional meter for me yet. Actually I can sell, but I just don't get any money from it. I think I lost some 3-500e last month because of that.
It seems my vertical/bifacial system is doing fine, but I think I can make it even better. Right now I just need to get it working automatically so I don't have to adjust it all the time.

These Deyes are driving me crazy. After producing about 270kWh today I went to change the mode to "selling first" as I do every night. This way I can make my batts to discharge and cover about 80-90% of my overnight consumption (because I have to estimate my hourly consumption and not overdo it to avoid selling power to grid for free). Can't use "zero sell to CT" as it immediately makes Deyes trip to off grid mode. Today was the first time I was having big difficulties to start discharging at all. Looking at the grid voltages from Deye menu, ph2 creeps up to 248V which seems to be the tripping point while discharging. Other phases can be 233-242V at the same time, but ph2 is always the highest one.
I need to check all my connections again, because in my simple mind that is the only reason for voltage increase. On the other hand my set was producing 30-40kW throughout the day, so any bad connection should have been vaporized already.

Golden hour.
Production steps up for the last two-three hours after being low for three hours due to bad panel angle. Panels would only need a really tiny movement to make huge increase in evening time production. Hmmm...

The beginning of a plan has formed. You will now spend endless nights thinking, unable to stop your brain, working out the intricate details of this plan until it is ready to be implemented

I think it took about three minutes to figure it out how I want to do it.The beginning of a plan has formed. You will now spend endless nights thinking, unable to stop your brain, working out the intricate details of this plan until it is ready to be implemented
I mean the mechanical part of it. Electronics to drive it are way over my head, so I need help there. I bet one of my engineering friends can help me there.To be fair I'm using only half of my MPPTs at the moment, so I think it would be wiser to add more panels in a different azimuth angle. And if I make it seasonally adjustable (azimuth) I can use it to boost winter production too. Although I already know my setup will do quite ok in winter conditions, only overpaneling will help to catch those scarce sun rays from October to start of February. Tilt movement will not help with that at all. I'm pretty sure I will at least try to make an automatically adjustable tilt for my current array later, but first things first.

Went through my connections today and found one that haven't been tightened at all (all 3 phases). Half of my array uses that connection (both GT inverters), but surprisingly no heat accumulation at all. Still can't make my Deyes to work properly...

10,8MWh already, which is over 1/4 of what PVWatts predicted for the whole year. This took 1,5 months to do.
The past weeks have been exceptional for solar power here, and except for a small break next week (we need some rain) it looks like it's going to continue for the time being.

glad you scandinavian brother have had a few good weeks.
here we've had the wettest , least sun hour spring since 1983

For some odd reason I haven't been this interested in weather before. Now I seem to notice every single cloud and even rate them for their opacity.

oh just wait untill the sun goes away for a week and heavy clouds stay..For some odd reason I haven't been this interested in weather before. Now I seem to notice every single cloud and even rate them for their opacity.
not sure if there is such a thing , but i been dancing the sun dance here
