Checking
1.
When the PV panels are connected and their output voltage is greater
than 100 V
DC
LCD display produce the following messages in order: "MODEL= CPS
SCxxKTL-x" -> "Waiting" -> "No Utility". The display repeats "No Utility"
and the RED "fault LED" turns on.

Close the AC breaker or fuse between PV-Inverter and grid. The
normal operating sequence begins.
