Malfunction
Various status messages and operating
modes are shown on the display. The dis-
play is found on the front of the SENEC.
Home Li at the top.
Always switch the SENEC.Home Li off via
the display. If you have switched the sys-
tem off via the display and restarted the
MCU on the AC side, you must switch the
SENEC.Home Li on again separately at the
display.
DC isolating switch
The DC isolating switch disconnects the
battery from the battery inverter. The bat-
tery is connected to the system when
the switch is in the ON position. When
the switch is in the OFF position, the bat-
tery is isolated from the system and is
being neither charged nor discharged.
Note: The DC isolating switch is not a mas-
ter switch. The system must also be swit-
ched off on the AC side in order to switch
off the system completely
