Status display
Meaning
Fault: Grid connection protection
on grid
Mains connection has detected a fault on the supply network and
is preventing connection to the grid. Possible causes:
•
voltage too high/too low (AC cabling of insufficient cross-sec-
tion and/or cable too long, poor grid at the feed point into the
house, too much or too little generation and/or consumption on
the domestic power network)
•
frequency too high/too low (remedial action by grid operator)
•
phase displacement between L1/L2/L3 too great (remedial ac-
tion by grid operator)
Fault: Grid connection protection
hardware
Grid connection protection is faulty and must be replaced.
Initial status
The system has not yet been configured.
Discharge capacity test
Run a manually launched capacity test. No normal operation
during the test – battery module is discharged at a constant ap-
proximately 500 W until the module is fully discharged.
Charge capacity test
Run a manually launched capacity test. No normal operation
during the test – battery module is charged at a constant approx-
imately 500 W until the module is fully charged.
No communication with charging
device
Communication between control unit and SENEC.Inverter is faulty
(example: faulty cable or lethal hardware fault in the SENEC.In-
verters).
No connection to server
The system expects a constant connection to the server – has
however had no connection to the mein-senec.de for a contin-
uous 24 hours and is now shutting down. Normal operation is
restarted automatically as soon as the connection is restored.
Charging
Normal operating status.
Charge completion phase
Normal operating mode. The battery is practically fully charged
and is being charged at lower power until it is detected to be Fully
charged.
Manual safety charge
The system is charging fully, as the user has triggered this man-
ually.
Mains & discharge
Normal operating status. The discharge output of the system is
not sufficient to cover the entire power demand. Electricity must
additionally be bought from the mains.
Restart
A system restart is imminent and will be run within 60 seconds.
Emergency charge
The battery charge level is too low. It will be charged with power
from the mains to protect the battery. Lithium systems charge until
they detect Battery flat.
Emergency charge: Fault
Error during automatic emergency charge. Battery modules will
soon be switched off for safety reasons; the system will pass into
sleep mode. A technician must be called.
NPU fault
Malfunction in the communications unit (NPU) or faulty commu-
nication between control unit and communications unit. A techni-
cian must be called.
Passive
Normal operating status. Neither excess nor feed-in are high
enough to trigger discharge or charging.
