(B) Gateway Memory Card Issues
i) No memory card
ii) Memory card not fully engaged
iii) Memory card not formatted as FAT32
Logging of long-term performance data is saved to the memory
card that was supplied with the Gateway. Note that the card is
not required for the system to operate, only to retain historical
information. If the card is in place but not fully engaged, the
SD
indicator (item
B
in Figure 37) will turn red.
The card is formatted with the FAT32 file system. If a different
memory card than the one supplied is needed, it will need to be
formatted similarly. This can usually be achieved on a personal
computer. Consult the computer manual for details.
(C) Gateway-to-Inverter Connectivity Issues
i) The Gateway is wired into an unrelated AC circuit
ii) The Gateway is too far away from inverter(s)
iii) The Gateway is the wrong side of filtering on the AC circuit
iv) Filtering present on the utility grid interfering with communication
The Communications Gateway connects to local inverters using Power Line Communications (PLC). For
communication to work, the Gateway must receive a strong enough signal to exceed any line noise. It must be
on the same electrical circuit as the PV system. This is not always easy to establish in a typical company
electrical closet with many different circuits present.
Assuming the Gateway is on one phase of the correct PV system circuit, then issues are likely to arise if the
signal strength is low. Issues are also likely to arise if equipment between the Gateway and PV system is
interfering with or filtering the signal. In either case moving the Gateway closer to the PV system is likely to be
the best answer.
It is also possible that two Gateways (or other inverter control devices from other manufacturers nearby) are
interfering with each other. In this case an isolating filter to separate the inverter communications from the
outside world might be required.
Note that a failure to establish communications can also occur if the neutral (white or grey) wire is connected
incorrectly to one of the phases as discussed in the next section.
(D) AC Wiring Issues
i) AC output of inverter not connected to grid
ii) AC connector not fully engaged
iii) One phase of AC grid not connected
iv) Neutral (white or grey) wire connected to a phase instead of neutral
v) Connected to wrong voltage system (480 Vac 3-phase)
