5.9 AC Connection

IMI Detection
The inverter has a built-in IMI/RCMU (Insulation
Monitoring Interrupter / Residual Current Monitoring
Unit). The inverter acts on residual DC current and a
sudden change in the ground fault current. This
functionality is activated during normal operation.
Insulation Resistance Detection
The inverter has a built-in insulation resistance
detection. The insulation resistance detector performs
a measurement of the connected PV system
resistance to ground before the inverter connects to
the utility grid. If the resistance is below the grid code
set value, the inverter will wait and re-measure the
resistance after a short while. If the resistance is
above the grid code setpoint, the inverter performs a
self-test and connects to the utility grid.
