    Alright, so based on my reading over at https://magesolar.com/best-portable-solar-generator/ , i have question on variation in panel output. My PV system consists of 2 sets of PV panels (13 Silevo 305W and 11 Panasonic 325W panels). Although my system was installed almost 2 yrs ago, I have only been monitoring output for 60 days. On the very 1st full day of monitoring, I saw substantial clipping at 5 Kw even though my inverter was an SE6000A.

    After about a week, SE determined that my inverter was set at a maximum of 5 rather than 6 Kw and they fixed the setting. However, during that week and since then I have only observed very brief periods of clipping (at 6 kw) by looking at pvoutput.com graphs for voltage jumps.

    When I compare the cumulative output of each set of panels, it comes out close to the 325/305 ratio (1.1 vs actual 1.2). However I see a moderate amount of variation in total output within each set of panels, see attached file. In the Panasonic set, the highest yielding panel was 115.1 KWh vs 94.7 KWh for the lowest. Is this amount of variation in output normal?
