Overview Inverter Kostal Pico


With this function block, data can be read from the Kostal Pico inverter. Newer models from this manufacturer can be read via Modbus; this block is used for communication with older devices that did not yet have Modbus implemented.




Outputs
ER
 Communication error
 not equal to 0 if the inverter cannot be reached or a query fails (e.g. at night when the inverter is switched off). The outputs then keep their last value.
PG Total production kWh Total production
PT Daily production kWh Daily production
LD Power DC W Power DC (sum of the three strings)
LA Power AC W Power AC (sum of the three phases)

Parameters
IP address
 IP address of the inverter
Port Port number (default 81)
ID
 ID (default 255)
Query interval Query interval in seconds (default 30). The first query is made 10 seconds after start.
I/O type “Simple”: outputs ER, PG, PT, LD and LA. “Extended”: additionally phases (L1 to L3), strings (S1 to S3) and status.
