WARNING –
B
Risk of electric shock. Hazardous DC voltages are supplied to the photovoltaic array during the night.
By external commands or by dedicated Web User Interface (UI), night-time reactive (Q -fix Mode or Volt/Var Mode) power can be enabled
or disabled and night-reactive power mode and set-point can be modified.
Thanks to smart microcontroller supervision, when night comes, i.e. input voltage falls below disconnection threshold, inverter enters
automatically night mode seamlessly: thus ac disconnection doesn’t occur in this case and inverter passes immediately from day to night
operation.
To enable the pre-charge board functionality entering in the Web UI using the Admin plus privileges.
3.11 Communication interfaces
The integrated ethernet and wireless board allows the local or remote connection to the inverter.
The inverter provide the following integrated communication interfaces:
•
Wireless channel (IEEE 802.11 b/g/[email protected])
The use of wireless channel is recommended to access to the integrated Web User Interface by using any WLAN standard device (PC,
tablet. smartphone) for commissioning and setting parameters. Additionally a second radio channel is available and can be used for
connection to a wireless router.
•
2x Ethernet ports (39) (40) (10/100BaseTx - RJ45 plugs)
The ports are configured by default for enabling daisy chain connection of the inverters over the Ethernet bus.
In order to improve the reliability of the communication with the inverters it is also allowed to create ring shape layout by using this
Ethernet bus.
•
1x RS485 ports (38) (terminal block)
The port enables daisy chain connection of the inverters over the serial line (slave mode). The port can either be used for connecting
supported accessories (like weather station, meter...): in this case data from accessories will be logged and transferred to the cloud by
inverter itself (master mode).
3.11.1 Ethernet bus connection
By default the two Ethernet ports
(39)
(40)
of the inverters are already configured for enabling communication over daisy chain layout.
Once the inverter is physically connected does not need specific settings: after the first turning on, the inverter automatically got all needed
network parameters with or without the presence of a DHCP server.
If an internet connection is available on site, the inverters will be automatically configured to transmit telemetry data to Aurora Vision Cloud
without the need of installing any additional device (logging capability are already integrated into the inverter by default).

Aurora Vision Plant Management platform is the Fimer cloud solution allowing customer to remotely monitor and manage
its own solar plants. Please refer to
or contact Fimer technical support for further information on how getting an
Aurora Vision account.
With the inverters connected over Ethernet daisy chain and with an available internet connection it will be always possible, via Aurora
Vision Cloud, to upgrade remotely the firmware of the inverters.
