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