Hi guys I have some problems with my work.My PV system uses the SMA inverter SunnyBoy 2100TL and when I kept the data from the Sunny webbox.The data at the waiting and grid-monitoring mode at the dc size have the voltage at 600 V while the maximum voltage that can generate from the PV at MPP mode is about 180 V.The waiting and grid-monitoring mode is operating at the morning and evening when the irradiance is only little.I don't know why it happen so I ask for your advice.
