The PV array Equipment Grounding Conductor (EGC) must be connected to the
GND stud bolt available in the inverter connection box.
The neutral conductor on the AC side of the system must be connected and solidly
grounded to the X0 terminal of the service transformer.
Monitoring
If Ethernet communications are used (typically with REFUlog), ensure that each
inverter has been assigned a different IP address and the protocol is set to "0".
If RS-485 communications are used (typically with 3rd party monitoring software),
ensure that each inverter has been assigned a different USS address and the protocol
is set to "1".
Startup
All equipment covers are closed before startup.
Close the AC system circuit breakers or insert the external main fuse.
Turn the DC disconnect to the ON position.
