8.2. TROUBLESHOOTING.

Problem
The inverter is powered
correctly but it does not
start and the message
"Waiting" appears on the
display while the green
LED flashes.
Zero injection is activated
and the inverter does not
generate power, even
though the installation
has load.
The red LED is flashing,
but the inverter is working
properly.
At night, no data appears
in the EQX-sun application.
I do not wish to connect
the inverter to the WiFi
network. Would this pose
a problem?

Solution
To start the inverter, in addition to receiving voltage
on the panels, it needs to be connected to the grid
to synchronise with it and ensure that it does not
work in the "island" mode.
Check that there is voltage on the terminals of the
circuit breakers that power the inverter protection
panel.
If the circuit breakers on the AC protection panel
are activated correctly, there might be another cir-
cuit breaker upstream that needs to be activated.
The CT may be wired incorrectly. The CT arrow
must be in the direction of the installation towards
the grid (connection side).
Read section "6.5.3. Installing the CT.".
The inverter only indicates that it does not detect
the WiFi antenna. However, the inverter is working
properly.
The inverter is powered by the solar panels. There-
fore, if the solar irradiance is not high enough for
the inverter to start, it will not be able to power the
WiFi antenna to send the data required to update
the application.
In order to monitor the installation 24 hours
a day, it is necessary to install the optional
devices 6B2OP000007 (485/WiFi 24H EQX)
and 6B2OP000008 (ESM1 EQX).
The inverter will work perfectly, since it does not
need to be connected to the Internet. In addition,
the most relevant generation data are shown on
the unit's display.
The WiFi antenna is only used to provide
installation data to the user as a means of providing
additional information and to manage and control
the system more easily.

8.3. MAINTENANCE.

Risk of causing damage to the inverter or personal injury due to
improper use.
Before using the inverter, observe the following procedure:
Danger
- Lower the AC thermal-magnetic circuit breaker and the inverter
DC switch.
- Wait at least 5 minutes for the internal capacitors to be fully
discharged.
- Check that there is no voltage or current before removing
a connector.
Keep all unqualified staff far from these areas!
A temporary warning sign or barrier should be posted to keep
unqualified persons away while performing electrical connection
Warning
and service work.
Restart the inverter only after removing the fault that affects safety.
Never replace internal components at random.
