(problem resolved)
Hello! I have a SUN2000 12kW inverter that works fine for most parts but on very sunny days a phenomenon accurs that I can not understand. I have a drop in power on PV3 during approx. 2 hours between 11am to 1pm.
1. It is only when it is sunny from early morning.
2. The drop is only for about 2hrs
3. It is always PV3. PV1 works perfectly.
4. It drops during the time it should be producing at its best(based on sun position)
Anyone with any idea of what could be the problem?
First image is for right now. Second image is for yesterday.

only from the current we cannot figure it out if it has some problem or not， the string is tracing the max power, if you want a future analyzing, please send logs to eu_inverter_support@huawei.com

Not sure what you mean by logs. I can not export nything from the neteco portal. I had to type everything into a excel file to calculate power. This is the result.

Can you help provide the following information: How many DC input strings are connected? How much is the output power of each group string?
