APsytems ECU-3 V8.0 Installation/User Manual 11 11
ECU INITIALIZATION SEQUENCE
NOTE: The complete initialization sequence can take several minutes
(up to 15 minutes depending on the complexity of the installation and the
overall number of inverters).
3. Operating Interface.
Router IP Address:
The LED screen on the front of the ECU displays an IP address such as
“192.168.2.101” if the connection to the router is successful (the IP address
will vary based on router supplier, so check with the user manual for
specics). If, however, the LED displays “60.190.131.228”, the ECU-router
connection has not been successful, in which case you’ll need to check all of
the cabling connections and reboot the ECU by removing the power cable
for a few seconds and reconnecting.
EMA Communication:
A “+Web” indicates that the ECU is communicating with the APsystems
EMA via the Internet. “-Web” is an indication that there is a problem and
the ECU is not communicating with the APsystems EMA.
PLC Signal Level:
The PLC signal strength measured from 1-5, with higher number being
stronger signal strength.
NOTE: Signal Level will not be displayed if there is no PLC, or if the ECU
has a UID less than 203000018226.
Current Power Production:
What the solar array is producing currently (in Watts).
Lifetime Production:
The lifetime power output of the system (in kWh).
