3.10.4 Configurable relays
This inverter is equipped with two configurable relays (33), which can be used in different operating configurations that can be set through
the integrated web user interface. A typical example of application is closing the contact when an alarm is triggered.
3.10.5 Remote switch-on/switch-off
This command can be used to switch off/switch on the inverter via an external (remote) command by means the Remote ON/OFF terminal
block (37).
This functionality must be enabled in the integrated web user interface.
When the functionality is active the switching on of the inverter, besides being dictated by the presence of normal parameters which allow
the inverter to be connected to the grid, also depends on the external control for switching on/off.
3.10.6 Reactive power feed into the grid
This inverter is able to produce reactive power and can feed this power into the grid via the power factor setting.
Power feeding modes may vary according to the country of installation and the local grid companies.
3.10.7 Limiting the active power fed into the grid
This inverter is able to limit the amount of active power fed into the grid to a desired and adjustable value.
3.10.8 Overvoltage surge arrester monitoring
The inverter monitors the status of the overvoltage surge arresters (19) (22) (53) and generates a warning in the event of a fault (viewable
via monitoring system, web user interface or Fimer Installer for Solar Inverters APP).
3.10.9 Data transmission and control
Embedded multi communication interfaces (WLAN, Ethernet, RS485) combined with a Sunspec compliant Modbus protocol (RTU/TCP)
allow the inverter to be easily integrated with any third party monitoring and control systems that support the same Sunspec standard.
NOTE – D The Modbus RTU/TCP register map is the same for all communication interfaces (Ethernet, RS-485 and Wireless
communication) of the inverter.
NOTE – D Please contact the Fimer technical support or get access to Sunspec alliance website for further information on Modbus
Sunspec products.
3.10.10 PVS-100/120 GROUNDING KIT
Grounding of the negative input pole is provided as an additional function only for dedicated inverter models. Alternatively it can be added
to other inverter models as an additional kit (PVS-100/120 GROUNDING KIT).
The grounding kit allows to connect the negative input pole of the PV array to ground (where is required by technical data of the PV
modules).
To enable the GROUNDING KIT entering in the Web UI using the Admin plus privileges (see “Connection to Web User Interface”).
Enter the Menu “Setting/Additional Function” and:
• Set as ENABLED the Grounding Kit (if is installed as an accessory on the field) with the proper selector.
• Set the “Max Vneg-gnd for Grounding Kit” (range: 0...250V); recommended value: 200V.
This parameter identifies the threshold voltage between negative pole and ground, which triggers the inverter disconnection for Ground
fault (E037).
WARNING – B If this accessory is installed this inverter must be installed and operated in restricted areas (restricted area:
Room or location for electrical equipment to which access is restricted to skilled or instructed persons by the opening of
a door or the removal of a barrier by the use of a key or tool and which is clearly marked by appropriate warning signs).
Access is limited to qualified personnel (qualified personnel: A person having appropriate technical training and experience
necessary to be aware of hazards to which that person may be exposed in performing a task and of measures to minimize the risks
to that person or other persons).
3.10.11 PVS-100/120 PRE-CHARGE BOARD KIT
Pre-charge board functionality is provided as an additional function only for dedicated inverter models. Alternatively it can be added to
other inverter models as an additional kit (PVS-100/120 PRE-CHARGE BOARD KIT).
Pre-charge board allows to recharge PVS-100/120-TL (B2 version) internal bulk capacitors from AC grid side: so doing,inverter is able
to connect to the grid even during night-time when no DC voltage is available from PV panels side. The main advantage related to this
feature is the possibility to realize night reactive power production when it is desired, i.e. night-reactive power on-demand. Most common
examples of nightreactive power on-demand are:
• Night-time reactive power demand after inverter disconnection;
• Recovery from AC grid disconnection during night-reactive power;
• Round scheme night-reactive power.
Inverters with pre-charge board are also able to satisfy immediately to request of night reactive power thatarrives during the night with the
ac grid interface contactors opened, since this board provides the capability to restore the grid connection.
Pre-charge board can also provide the possibility to restablish normal operation when a grid fault provokes disconnection of the inverter.
For example, during night time, when inverter is in night reactive power mode, if AC voltage dip occurs, inverter disconnects from the grid.
For inverter with precharge board installed, night reactive power can be restablished also after grid dips.
