When my Growatt 11000tl3-x starts up in the morning, the string voltages rise until about 600V. Once the panels start giving power, both string voltages drop until about 150 volts. Within half an hour, one string goes back to its normal voltage (about 550V) but the other string stays low at about 220 V.
After a reset on the inverter or a reboot from the webportal, the string voltages are both normal.
The string current is quite normal
One string is connect to east, 17x400Wp (more sun in the morning) and the other string west 16x400Wp (more sun afternoon). It can happen with both strings. The east string is getting worse.
