Setting string input number
The standard types of Sungrow PVS are:
PVS-8M
PVS-12M
PVS-16M
If the strings input are 8, 12 or 16, there is no need to set any parameter.
This section introduces the communication setting method of the PVS when the
string inputs are 15 (the product user received is PVS-16M).
If the real strings input do not correspond to the abovementioned input number, set
the parameters according to the following steps to ensure the normal
communication of the PVS.

After power on, the monitoring board on the top left of the PVS internal
works normally.

are “P=0” or “P=1”, the PVS is in Setting status as shown below.
Step 3
Press the key switch A1 to select the input string number, for example 15.
Step 4
Press the key switch A2 and turn the last digit of the LED to “0”, i.e. “No input”.

th
input needs to be set to “No input”. The
LED is shown as below.
