Problem Cause and corrective measure
No inverters or not all inverters report
back with the version number of the
sent update file.
Due to missing DC input voltage to the inverters, an up-
date file has been sent and saved in the inverter but has
not yet been run. The DC input voltage can vary depend-
ing on the time of day, the weather or the condition of the
PV modules (e.g. pollution or covered with snow).
Corrective measures:
• To start the update directly, perform a manual update
(see Section14.2.2, page80).
After five attempts, the update file could not be sent to the
inverters in the system.
Corrective measures:
• Check the status of the Speedwire connection of the
inverters via the menu Instantaneous values >
System communication. Note that the Speedwire
connection may also be interrupted due to lack of
DC input voltage to the inverters. The DC input
voltage can vary depending on the time of day, the
weather or the condition of the PV modules (e.g.
pollution or covered with snow).
• To start the update directly, perform a manual update
(see Section14.2.2, page80).
EnergyMeter
Problem Cause and corrective measure
The EnergyMeter is not displayed
by the ClusterController.
The network cable has not been correctly connected to the
EnergyMeter.
Corrective measures:
• Make sure that the network cable is correctly connected
to the network terminal of the EnergyMeter (see
installation manual of EnergyMeter).
The EnergyMeter is not located in the Speedwire network.
Corrective measures:
• Depending on the network topology of the system,
connect the EnergyMeter either to the router or network
switch of the Speedwire network, or directly to terminal
X9 or X10 of the ClusterController.
The EnergyMeter is supplying un-
realistic measured values.
The EnergyMeter has been installed the wrong way round.
Corrective measures:
• Reconnect and recommission the EnergyMeter (see
installation manual of the EnergyMeter).
