Ethernet Network Card
A maximum of 32 devices can be connected to this card. When provided with an internet connection, it can send
data to an online portal that Yaskawa Solectria Solar can use for troubleshooting and remote diagnostic purposes.
As well, customers can opt to purchase access to this portal for easy O&M of their system. It is also used for
allowing the connection of a third-party monitoring system.
Connection to the Internet
Connection to the Internet with the Ethernet Network Card is strongly recommended for SOLECTRIA PVI 25TL-208,
PVI 50TL-480, and PVI 60TL-480 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.
 Remote monitoring via SolrenView (optional).
 Capabilities of using the optional YConnect Pro Portal.
Electric Shock Hazard: Disconnect the inverter from the AC grid and PV modules before removing covers or
opening the equipment. Wait at least 5 minutes after disconnecting from the DC and AC sources before servicing
or maintaining the inverter. Ensure hazardous high voltage and energy inside the inverter has been discharged
prior to servicing.
