Manual Energy Storage Inverter ESI-S
Fault message
Cause
What to do
Wrong phase rotation The supply network
feeding the inverter has
the wrong phase rotation.
−
Check the phase rotation of the
inverter supply.
−
Measure the three line voltages and
check if they are within limits.
−
Measure the line voltages (e.g.
voltmeter) and compare them with
the line voltages given by the inverter
(ESI-Manager or PQF-Link).
−
Check the AC voltage measurement
connectors (P6-1 to and P6-4) for
loose connections and component
damage.
−
Check the connections between the
auxiliary fuses and the AC voltage
measurement connectors (P6-1 to and
P6-4).
Global BESS fault
An error appeared during
a BESS application
(islanding)
A limit on the battery or on the inverter
has been reached. Since the system is in
islanding, it stopped. The limitation can
be on the battery current, cell voltage,
cell temperature or on the inverter
current.
Remark:
If the problem persists, contact your ABB service provider. Provide him with all the relevant
information, i.e. Inverter serial number and type, status of the control LEDs, Error messages
displayed and inverter behavior.

What to do
Com. Problem (RS-

Communication problem
between the main
controller board and the
external PC
−
Ensure that the PQF-Link cable is
properly connected.
−
Contact your ABB service provider.
Ctrl overtemperature The system detected an
overtemperature of the
main controller board.
−
Verify the ambient temperature and
the cooling of the inverter (dust
inverters, fans, heatsinks, …)
−
If the ambient conditions and the
inverter cooling are ok, the main
control board is suspect. Contact
your ABB service provider. The main
control board may have to be
replaced.
Reactor

Line reactor thermal
switch has open
Check the status of the reactors and the
PCB output inverter
PWM check cooling
The thermal switch in the
PWM reactor has open
Check the “fan out” status
