● Local maintenance refers to operations performed after a USB flash drive, a WLAN
module, a Bluetooth module, or a USB data cable is inserted into the USB port of the
solar inverter. For example, local maintenance includes data import and export using a
USB flash drive, and connecting to the SUN2000 app over a WLAN module, a Bluetooth
module, or a USB data cable.
● If the alarming and the local maintenance happen concurrently, the alarm/maintenance
indicator shows the local maintenance state first. After the USB flash drive, WLAN
module, Bluetooth module, or USB data cable is removed, the indicator shows the alarm
state.
