Product Features
The IoT cloud-based gateway integrates various hardware and system scenarios.
Multi-model device topology using one RS485 daisy chain.
RS485 pass-thru ( 3rd party controller always acts as master in daisy chain )
Automatically diagnose RS485 wiring problems.
Modbus TCP pass-thru ( The 3rd party controller can R/W the RS485 daisy chain
at any time through Modbus TCP )
Built-in 4G modem ( SIM card included when purchasing the connectivity package,
which includes the ENC-G5 gateway card, a SIM card, and access to the
YConnect Pro Portal )
Easy mass deployment and configuration via APP using built-in
Bluetooth Low Energy (BLE).
Plastic DIN rail enclosure (included) supports side and flat DIN-rail mounting.

SIM Card Slot
The ENC-G5 gateway comprises two boards, the Main Board and the Daughter Board. The Daughter Board includes a
SIM card slot for easy 4G Internet connectivity with the use of the otional SIM card products. The ENC-G5 gateway
supports the use of the optional Yaskawa Solectria Solar YConnect Pro Portal.
The ENC-PORT-C532 Connectivity Package product allows for 4G connectivity of up to 32 inverters for 5 years. The
ENC-PORT-C510 Connectivity Package product allows for 4G connectivity of up to 10 inverters for 5 years. Both of
these products come with the capability of accessing the Yaskawa Solectria Solar YConnect Pro Portal for 5 years.
Note :
The ENC gateway is not compatible with third-party sourced SIM card. The Yaskawa Solectria Solar technical support
team will not be able to assist in the implementation of third-party SIM cards with this gateway.
ENC gateway hardware warranty is valid by default within the validity period of our data plan.
1) Push in the direction shown to unlock the flap
2) Open the flap
Then, insert the SIM card into the flap along the slot
in the flap. Fold the flap and SIM card into place on
the SIM card holder
3) Push in the direction shown to lock the flap

Internet interface : Ethernet
If the gateway is connected to the Internet using Ethernet instead of 4G.
Open the LAN firewall ports before commissiong !
The following ports must be opened both ways (incoming and outgoing
communications):
TCP 1884 with destination IP 47.254.52.209
TCP 443 with destination solrenview.com (IP 209.160.64.80)
Internet interface : 4G
ENC SIM card provided in the ENC-PORT-C5XX Connectivity Packages
supports AT&T + T-mobile networks.
After the gateway is powered on and working, it will select and connect to
the provider network with the strongest or most stable signal.
If you are interested in a Yaskawa Solectria Solar Connectivity Package,
please contact the YASKAWA Solectria Solar US sales team for detailed
information.

Remove the (3) screws that attach
the inverter communication board in
the Wire-Box using a #2 Phillips bit.
2Replace the screws with the (3)
standoffs included in the gateway kit.
Install the gateway by carefully align-
ing the 6-PIN connector in the upper
left-hand corner of the communica-
tion board.
Install the (3) screws into the stand-
offs to secure the gateway in place.

Ethernet Port
Connect the 3rd party Datalogger to the AUX port in the bottom left-hand corner of
the gateway using the 3-Pin Connector provided in the gateway kit.
Connect the RS485 inverter daisy chain to the inverter communication board using
the 5-Pin Connector provided in the gateway kit.
NOTE: The 5-Pin Connector is installed on the port on the bottom of the inverter
communication board (behind the gateway) .
The RJ45 LAN cable is inserted into
the Ethernet port of the gateway.
The LAN cable must be able to access
the Internet without port filtering
behind the firewall.
