I commissioned my on grid solar plant in December.
I run an SMA Sunnyboy 8.0 inverter with 11.7kWp worth of solar panels.
Where I live, it's a very remote corner of the world so we have frequent powercuts. Whenever we lose power, my inverter app showed Ground PE connection missing error. Since, I was the installer I double checked all the wirings and it was fine. I read somewhere online that it could be a bug in the software showing a false negative.
Yesterday, for the first time I got a DC overcurrent error at 6:48pm as in when it's almost dark outside and the production was around 0W as shown below.
Is this a bug? The irregularity in production yesterday was due to power cuts and clouds. Down below is what today looks like, produced above 50kW.
This is what the instantaneous value of DC side shows when the production is at it's peak (producing 8000W in the afternoon)
All are well below the maximum limits. Am I missing something? Please and thank you.
I am not an expert at this, everything is self-taught and since I live in a remote part there are no experts to be hired or called in.
