The a-TroniX Controller supports Kostal Pico inverters that use the "Kostal Pico protocol". This includes many inverters from the PIKO series.

Curtailment While these inverters support active power control and feed-in limitation, the protocol driver used by the a-TroniX Controller does not currently support sending curtailment commands.
Kostal inverters can be connected to the a-TroniX Controller via Modbus TCP (Ethernet) or RS485.
The default RS485 bus address is often 1. If you have more than one inverter on the bus, you must assign a unique address to each one. This can typically be done via the inverter's display menu or web server.
The physical RS485 connection varies by inverter model. Please consult your specific inverter's installation manual for the correct terminals and pinout.
Connect the inverter's RS485 terminals to the a-TroniX Controller as follows:
| Device | a-TroniX Controller model OM1 | a-TroniX Controller model IG8 | RS485-USB converter | RS485-Ethernet converter |
|---|---|---|---|---|
| Data A | RS485 A | RS485_POS | RS485 A | TX+ |
| Data B | RS485 B | RS485_NEG | RS485 B | TX- |
| Ground | RS GND | GND | Not available | G |
