FAQ
After
anti-crosstalk
parameters are
set, the number
of the detected
inverters do not
match that of the
inverters in the
subarray.
Inverters cannot
be networked
through PLC.
Issue 12 (2019-01-15)
Possible Causes
1. The inverters in other
subarrays are detected.
2. The SN list is incorrect.
3. The three-phase input
switch on the smart
array controller is off.
4. The switch between the
SmartLogger or PLC
CCO module and the
busbar of the
transformer station is
off.
5. The three-phase AC
power cable is a single
core cable.
The PLC board is faulty.

Suggestions
1. Do not set the anti-crosstalk
parameters for the subarray until the
operation is performed on other
subarrays.
2. Check whether the SN list and SNs
of the inverters in the subarray are
consistent.
3. Turn on or replace the three-phase
input switch on the smart array
controller.
4. Turn on or replace the switch
between the SmartLogger or PLC
CCO module and the busbar of the
transformer station.
5. In the US, set Network frequency
band to 1.7–4.9 (MHz). In other
regions, set this parameter to 0.5–3.7
(MHz), 2.5–5.7 (MHz), or 2–12
(MHz) as required.
