I’m disappointed I didn’t spot it.
Right - who else thought that looks like something else :-) ? LOL
I thought I’d finally crack 50kWh today but topped out at 47. An almost perfect curve though, apart from that single stray cloud at lunchtime.
Yeah, my inverters are outside on a wall so not roasting in an attic. So looks like panel heat for me, not inverter heat. We'd a 22% drop in highest output today (clear blue sky scorcher) compared to a sunny but cooler more cloudy Sunday. Thought got more output overall today compared to that day. I hit over 100% of the string capacity that Sunday at times (2.8kw when max is 2.7). But the curve was like the blades of a saw (up and down). Only hit max of 2.1kw today on that string but beautiful curve (1st textbook curve we've seen since went live a few weeks ago).
Going to be close to yesterdays record again, another 20kWh exported.
Boards.ie keeping the grid alive 😅
Its the panel heat, in may/June id flatline at 6kw with 8kwp
This weather I hardly break 5.5kw.
@slave1 if you're a Zappi export, pop over to the PV troubleshooting thread...
With the Zappi it defaults on Eco+ to turning off after 30seconds e.g. dark clouds passing, but you can change this in the settings to extend up to 2minutes, this is what I have done and leave on Eco+ only
On the subject of Inverter cooling, I was thinking about ordering a PS4 cooler. The auto mode runs when it’s above 40deg and it’s powered by USB

There's those smooth curves I've been missing.
If your stuck you can wire a 3 pin socket off the EPS outlet on your inverter yourself ?
Yes definitely considering something the only issue I'll have is the lack of easy access to a socket!
Put a fan on a smart plug or similar blowing cool air at the fins on it, most here have something rigged up for when it gets too hot.
I found it in the Solarman app. The inverter is currently 64.5c I think it starts derating at 45c so well over that and close to the shutdown temp of 65c!
I'm maxing out today at just over 5kW on a 7.44kWp system and 6kW inverter.
Panel heat the likely issue, plus of course we're now into August so the angles are changing.
Currently south string is at 3 of a possible 4kW. West string is on 2.1 of a possible 3.4kW.
Any idea how can I tell if the heat is affecting the inverter? Or is it the panels? I've 4.2kwp of panels e/w orientation with a 3.6kw inverter and usually see it clipping but this week, with clear skies I've struggled to get above 3kw.
I bought 3kWh today, gutted. Had a timed boost set on the car but forgot to limit it to 2kW rate. Ended up blasting the full 7.2 at it until I realised.
This is a graph of beauty...blue line is the Zappi and the red is the PV....pushing 4kW into the EV since about 11am this morning 👌
I am shifting my Zappi strategy to start using the Eco setting and not Eco+. On a day like today I dot think its too much of a difference but if there are clouds I don't really like it kicking in and out all the time if it drops below the set level.
Produced 42.2 kWh yesterday and the car is only at 50% so I can push about 23 kWh into that today.
And the irony is that our "cold" water tank feeding the shower is in the attic so not cold at all today so hardly any need to supplement it with hot water from the cylinder. The app is great, couple of seconds and the EV now taking all the surplus
Time to fill the hot tub? Lol
WFH today, was wondering why I could hear the hot cylinder "boiling", forgot to put Zappi to Eco+, ah well, no great loss
Mine was all over the place yesterday, we had high scattered cloud
South
West
Combined
I think 11:30 is when the shadow of the chimney goes away as the sun hits the house directly.
But you have two separate panel aspects from memory, what does it look like for each individually, my "combined" is same as yours
New record of 43.7kWh yesterday, 4 to Eddi, 19 exported and busy with the appliances.
65kwh exported over the 5 days, would have filled an EV. Might put a sign up 😜
All going well I should hit 1MWh for my install around tomorrow afternoon/evening. Less than 2 months since install. 😎
EDIT: just checked and it's just a couple of days shy of 2 months.
Maybe because it's shorter update intervals and not 5 mins?
Yup, I think you answered your own question there. Mine is also 5 mins telemetry, infact I think you have pretty nice smooth curve there all things considered. Although it's interesting there what happened at 11:30 on your first chart.
Even still, compare how smooth your best curve is to mine.
It was lovely out but there was some high cloud, brief but still a shadow.
