Weird Solar/PV generation issue

[YRide]

I’ve had 10kW PV and 4x ESS for over a month now…working pretty good mostly after all the install fun, weird turn-on settings issues, etc.

For the first several weeks PV generation looked very consistent. First three pictures below. However, more recently, say last two weeks…the PV drops out multiple times in the afternoon (last 3 pictures). Any idea what’s up? Am I actually losing generation? Is something overheating in the inverter? Or are the CT’s just not measuring accurately? Other?

Any insight is appreciated!!

Looks like an inverter cooling issue from what I’ve seen with other posts of similar issues here. You must have more than one inverter and that is why production doesn’t drop completely off when one of them is overheating during peak generation.
