The data is there in the cloud app if you go to the Device /Inverter /Parameter section.
That is showing the same issues I posted earlier.
Solar pv issue= solis hybrid inverter 6kw with about 30 panels of mix of 340kwh and 300kwh on another string plus 2 x pylontech batteries. The inverter stopped working this evening despite several power cuts in recent weeks by esb in my area. Tried tripping switch on mains fuse board etc to no joy. Dead as a doorknob!
Just copped these warnings on the solis app. Is the dc over voltage warning related to having too many panels for a 6kw inverter? Installer warned me this maybe an issue?
Yep, most likely. Pull out the DC current and voltage graphs for PV1 and PV2 from today from the app and post them up.
The panels may need to be generating to start the inverter again after shutdown
Is this what you mean thanks?
Started getting readings back now.
How many panels have you got?
My solis cloud app just updated on android. Looks right again now
Are folk still having connection issues on iOS (Solis).
I've had nothing since yesterday. and its looking like being a potential record breaker today!!!
14 roof mounted West facing and 16 ground mounted south facing
Did it wake up this morning? Are the pylontech batteries turned on?
The 16 panels are too many, (as when there is no load on them, the voltage passed 600v)
Had 12 on and added 4 recently so that maybe the culprit. Any work around outside getting a second inverter?
Batteries turned on and can bus failure rectified. Though still not operational
Alarm still showing
Are you able to post up DC voltage and DC current for both strings? From the DC voltage you posted, it looks as if you crept up over the MPPT max voltage (520V) at circa 17:30, DC over voltage fault occurred which disconnected the load, shoving the voltage up even higher to circa 640V.
Yeah that's prob it, no real way round it other than another inverter, possibly a micro inverter, but that would require running extra cables, 2 more dc cables out there.
Could re-configuring the string so it is instead two parallel arrays of 8 in series connecting to one MPPT work ?
Ive looked into that before but that's way above the current limit of the inverter unfortunately
Clipping? Presumably heat related. Its a 5kW inverter (awaiting upgrade) but I've regularly hit 7kW generation on cooler days.
Array 1 hitting 3.03 on a 4.03kWp max (75%)
Array 2 hitting 2.32 on a 3.41kWp max (68%)
Possibly could be to do with the colder days and the panels over producing. Not at home today, but I'd say it's pretty hot. (For us!) Steady state power is always less than spikes
As the sun moves round the west will pick pick up more as the south drops
Yeah balancing now with the west catching up.
Interestingly I saw a guy on Facebook today with a 7.9kWp system and Solis 6kW inverter. He's limiting at the exact same level, 5.23kW.
Have you got your fan going? What is the internal inverter temp at?
Fan was running but the core temp was about 52°
Whats interesting with my inverter the german subsiduary have a spreadsheet (in german) where you can fill in number of panels and conrfiguration of parallel/series etc and it will let you know if that is acceptable, for scenario like this definitely 16 panels the voltage is way to high, but for current when running two strings of 8 in parallel the current is reported as a warning "limitation at x%" which i took to mean inverters can handle this but lets say the two parallel strings should output 19A due to this being so high the MPPT brings this back to a value it can handle.
Went again after a while this morning. Still gone.
Same. Solis home app is still good
Under what settings menu is that info?
I checked it in the app.
