Heila PMC Communications (option)
If the Heila option is chosen for the PMC, the inverter MODBUS TCP/IP network and the Heila Edge
controller are prewired to the network switch inside the Heila control cabinet. Install two separate Cat
6 Ethernet cables to the network switch inside this cabinet, one with access to the internet, one
connecting to the battery management system. If the customer is providing their own PMC, call Yaskawa
Solectria Solar for correct installation.

Connection to the Internet
Connection to the Internet is strongly recommended for SOLECTRIA XGI 1500 inverters. An internet
connection will provide the user with several important features, including:
Automatic firmware updates.
Remote diagnostics & troubleshooting.
Access for Yaskawa Solectria Solar Technical Support & Service.
Access to the user interface via the Remote Access Portal (RAP) (with subscription, optional).
Never run communication conductors in the same conduit as power conductors. It is important to keep
communication conductors away from power conductors to reduce noise. If power conductors must
intersect with communication conductors, it is preferable to have the intersection at a 90 degree angle.
