I can see that being a problem. what are you having to do to get it to recognize?
Yeah I was using just 2 panels. In the morning (but in full shade) I was getting about 75vc. At solar noon on a warm day, it droped to beteen 68-60 and sometimes feel below that. I found that in full sun, when first staretd up, both the Growatt 12k and the 48v 120amp Growatt SCC both would start, but then in about 5 minutes stop sendind amps and power to charging. When I doubled the panels, so far (3 days of testing) all PV inputs have worked
I think on the disk might have been the manual? And maybe PVKeeper as the software. I got the 64 bit version of PVkeeper to work after I told Win 10 to run it as an administrator. The usage display is lacking, but PVKeeper does let me change all settings of the Growatt 12k on the PC. Have not tried it yet for the SCC.
What exactly is happening? What is the Issue? Is it a fault Code? No PV volts? No PV charging?
No PV Charging. The voltage is there but the inverter does not appear to see it. There are no panel icons on the screen and the inverter will just not switch into charge mode.
Interesting, When I was running only 2 panels, I was was not getting charging but I was seeing voltage. My input voltage was too low (59-70vdc). BUT ... I was seeing the panel icon on screen AND the charge light was flashing. Increasing the number of panels and subsequently the DC input voltage seemed to have fixed the issue. I hope you get that sorted out.
It's weird. it will work flawlessly for weeks or even a few months at a time and then just out of the blue, for no reason I can figure out, it will just stop charging. One time I did not notice it right away and it was down for several days (before I noticed it) and then the next morning (when I was about to drive up there to fix it) it started back up all on it own. I think it was down for 3-4 days in a row and then it started working again.
Are you using the 12kw? If it were possible, you might want to try a second charge controller and bring half your array in to the inverter AIO and half to the scc.
I am having the same issue. I have to do a complete hard boot of the inverter to get it to re-engage. I seem to remember some time ago, the unit restarted on its own. I have this issue on colder mornings, 0C. I am well below the stated 250VDC OC limit of the unit---199VDC OC. And have gotten a thumbs up from Sig Solar on the system design. I tend to believe is has to do with this upper limit of PV input, as it only happens on winter mornings.
Time (probably next Jan in FL) will tell. We did the full farm install 3 weeks ago. 16 x 370w panels. Input voltage is about 186v dc at 50*F
I am never up early enough to put an eye on my panel input voltage. Only suspect that in the lower 30s it would be cranking out the watts. Will keep you posted on what i find.
I do. But am having some difficulty to get it uploaded. Tried to load in resource section. But did not allow, said it was too large.
I had this happen again last week but for only one day and the next day it started again on it own. I still have no idea what could be causing it. I notice last week that the previous day does not seem to end (it shows the previous days kWh all day) on the day it did not activate as opposed to showing zero kW hours generated.
