    Hello everyone. I have a PV array, with two strings, both with 18 panels, one with 16 on south and tow on east and one with 12 south and 6 east. On te second string mentioned, in the morning, even if I do not have shade in my area, for few hours, the voltage decrease around 160 V and the current increase, and on the other one the voltage is normal. I have a Huawei 15 KTL inverter. After few hours, the strings become equals as voltage. I really didnt discovered what can cause this situation. Please give me any advice or solution if you met something similar in your experience. Thanks
