5. Choice of installation location
Environmental checks
- Consult the technical data to check the environmental parameters to be observed
- Installation of the unit in a location exposed to direct sunlight must be avoided (otherwise the warranty will be
cancelled) as it may cause:
1. power limitation phenomena in the inverter (with a resulting decreased energy production by the system)
2. premature wear of the electrical/electromechanical components
3. premature wear of the mechanical components (gaskets) and of the user interface (display)
- Do not install in small closed rooms where air cannot circulate freely
- To avoid overheating, always make sure the flow of air around the inverter is not blocked
- Do not install in presence of flammable materials in the close surroundings (3m minimum distance)
- Do not install on walls made of wood or flammable materials.
- Do not install in rooms where people live or where the prolonged presence of people or animals is expected,
because of the high noise level that the inverter produces during operation. The level of the sound emission is
heavily influenced by where the inverter is installed (for example: the type of surface around the inverter, the
general properties of the room, etc.) and the quality of the electricity supply.
Installations above 2000 metres
On account of the rarefaction of the air (at high altitudes), particular conditions may occur:
Less efficient cooling and therefore a greater likelihood of the device going into derating because of high internal temperatures
Reduction in the dielectric resistance of the air that, in the presence of high operating voltages (DC input), can create electric arcs (discharges) that can
reach the point of damaging the inverter
All installations at altitudes of over 2000 metres must be assessed case by case with the FIMER Service department.
Installation position
-Install on a wall or strong structure capable of bearing the weight of the equipment
-Install in safe, easy to reach places
If possible, install at eye-level so that the display and status LEDs can be seen easily
Install at a height that considers the heaviness of the equipment
Install vertically with a maximum inclination of +/- 5°
Choose a place with enough space around the unit to permit easy installation and removal of the
object from the mounting surfaces; comply with the indicated minimum distances
For a multiple installation, position the inverters side by side; if the space available does not allow
this arrangement, position the inverters in a staggered arrangement as shown in the figure so
that heat dissipation is not affected by other inverters
Final installation of the inverter must not compromise access to any disconnection devices that
may be located externally.
Please refer to the warranty terms and conditions available on the website and evaluate any
possible exclusion due to improper installation.

6. Assembly Instruction
Wall mounting
-During installation, do not place the inverter with its front facing towards the ground.
-Position the bracket (01) so that it is perfectly level on the wall and use it as a boring
template.
-Drill the 3 holes required using a drill with 10mm bit. The holes must be about 70mm
deep. On bracket (01) there are 3 fastening holes.
-Fix the bracket to the wall with the 3 wall anchors, 10mm in diameter, supplied. (Step 1).
-Hook the inverter to the bracket springs in correspondence with the insertion points in
the bracket on the back of the inverter (Step 2).
-Drill 2 holes in correspondence with the slots on the inverter lower bracket, using a drill
with a 10 mm diameter bit. The holes must be approximately 70 mm deep.
-Anchor the lower part of the inverter using No. 2 plugs with a diameter of 10 mm,
supplied (Step 3).
-Unscrew the 6 screws and open the front cover (03) in order to make all the necessary
connections.
ATTENTION –ADo not open the inverter in the case of rain, snow or a high level of
humidity (>95%)
-Once the connections have been made, close the cover by tightening the 6 screws on
the front to a minimum tightening torque of 1.5 Nm.
7. Input configuration (DC)
All versions of the inverter are equipped with two input channels (therefore with double maximum power point tracker MPPT)
independent of each other, which can however be connected in parallel using a single MPPT.
Configuration of independent channels (default configuration)
This configuration involves the use of the two input channels (MPPT) in independent mode.
This means that the jumpers between the two channels (positive and negative) of the DC input
terminal block (14) must not be installed and the switch (17) located on the main board must be set to “IND”.
Configuration of parallel-connected channels
This configuration uses the two input channels (MPPT) connected in parallel.
This means that the jumpers between the two channels (positive and negative)
of the DC input terminal block
14
must be installed and the switch
17
located
on the main board must be set to “PAR”.
8. Input connection (DC)
WARNING –BCheck for correct polarity in the input strings and absence of any leakage to ground in the PV generator. When exposed to sunlight,
the PV panels supply DC direct voltage to the inverter.The inside of the inverter may only be accessed after the equipment has been disconnected
from the grid and from the photovoltaic generator.
WARNING –BWarning! The inverters to which this document relates to are WITHOUT ISOLATION TRANSFORMER (transformer-less). This type
involves the use of insulated photovoltaic panels (IEC61730 Class A Rating) and the need to maintain the photovoltaic generator floating with respect
to earth: no pole of the generator must be connected to earth.
For the string connections it is necessary to use the quick fit connectors (usually Weidmüller PV-Stick or WM4, MultiContact MC4 and Amphenol H4)
located on the bottom of the mechanic (09)(10).
-Check the quick fit connector model on the inverter (checking the conforming corresponding part on the
manufacturer’s website) and crimp the respective corresponding parts of the DC connectors to the string cables.
ATTENTION –AUsing corresponding parts that are not compliant with the quick fit connector models on the
inverter could cause serious damage to the unit and lead to invalidation of the warranty.
-Connect all the strings included in the design of the system, always checking the tightness of the connectors
and checking the input polarity is correct.
WARNING –BIn the -FS version each input is supplied with protection fuses (not factory
fitted) and an input polarity control. To check the polarity, connect all the strings and check
that the LEDs on the fuse board (13) are lit up; if one or more LEDs is off, the polarity of
the corresponding strings is to be considered INCORRECT. Once the check has been
carried out, DISCONNECT the strings and, checking there is no voltage at the DC inputs,
install the protection fuses (supplied) with the aid of fuse holders; reconnect the quick-fit
connectors. Check also that the fuse current rating is the correct size for the photovoltaic
modules installed.
-If some of the string inputs should not be used you must proceed to verify the presence of covers on DC input connectors and then install them should
they be absent: this operation is necessary for the tightness of the inverter and to avoid damaging the free connector that could be used at a later date.

9. Line cable and protection devices
Load protection breaker (AC disconnect switch) and line cable sizing
To protect the AC connection line of the inverter, we recommend installing a device for protection against over current and leakage with the following
characteristics:
PVI-10.0-TL-OUTD PVI-12.5-TL-OUTD
Type Automatic circuit breaker with differential thermal magnetic protection
Nominal Voltage / Nominal Current 400 Vac / 20 A 400 Vac / 25 A
Magnetic protection characteristic B/C
Number of poles 3/4
Type of differential protection A/AC
Differential sensitivity 300 mA
FIMER declares that the FIMER transformerless inverters, in terms of their construction, do not inject continuous ground fault currents and therefore there
is no requirement that the differential protection installed downstream of the inverter be type B in accordance with IEC 60755 / A 2.
Characteristics and sizing of the line cable
For the connection of the inverter to the grid, you can choose between a star connection (3 phases + neutral) and a
delta connection (3 phases). The cross-section of the AC line conductor must be sized in order to prevent unwanted
disconnections of the inverter from the grid due to high impedance of the line that connects the inverter to the power
supply point.
Cross-section of the line conductor Maximum length of the line conductor
PVI-10.0-TL-OUTD PVI-12.5-TL-OUTD
4 mm² 34 m 28 m*
6 mm² 51 m 42 m
10 mm² 85 m 70 m
16 mm² 136 m 113 m
* Up to 45 °C Ambient temperature
The values are calculated in nominal power conditions, taking into account:
1. a power loss of not more than 1% along the line
2. copper cable, with HEPR rubber insulation, laid in free air
10. Output connection (AC)
WARNING –BWarning! Before performing any of the operations described below, ensure the AC line downstream the inverter has been correctly
disconnected
-Remove the protective film located on the hole to be used for the AC cables (11)
-Insert the M40 cable gland in the hole and secure it using the special M40 lock nut (supplied)
ATTENTION –AWarning! To ensure environmental protection IP65 it is necessary to fix the cable gland to the inverter
chassis with a minimum tightening torque of 8.0 Nm
-Strip 10 mm of sheathing from the AC grid connection cables
-Plug the AC line cable into the inverter, passing it through the previously installed cable gland
-Connect the protective earth (yellow-green) cable to the contact labelled with the symbol on the terminal block (15)
WARNING –BWarning! FIMER inverters should be earthed (PE) via the terminal with the protective earth label , using a cable with an appropriate
cross-section of the conductor for the maximum ground fault current that the generating system might experience
Connect the neutral cable (normally blue) to the terminal labelled with the letter N
N.B.: When connecting to the AC grid in “delta” configuration (without neutral wire) turn the grid type selection
switch (16) with the screen-printed marking “3PH MOD” and set it to “3W Δ”.
Connect the phase cables to the terminals labelled with the letters R, S and T
ATTENTION –AWarning! The AC cables must be tightened on the terminal block with a minimum torque of 1.5 Nm
Once the connection to the terminal board (15) is complete, screw in the cable gland firmly (tightening torque 5.0Nm) and
check the tightness.
11. Connection of the communication and control signals
Each cable which must be connected to the connectors of the communication and control signals must pass through one of the three service cable
glands (12).
An M20 cable gland (that takes cables from 7 mm to 13 mm in diameter) and a gasket with two holes to insert into the cable gland which enables two
separate cables of a maximum diameter of 5 mm to be accommodated, are available
ATTENTION –AWarning! To ensure environmental protection IP65 it is necessary to fix the cable glands to the inverter chassis with a minimum
tightening torque of 7 Nm
Connection to the RS485 communication line
The RS485 communication port is the inverter’s communication port. The FIMER inverters use an RS485 HALF-DUPLEX communication line made
up of two transmission and reception cables (+T/R and –T/R) and a communication reference cable (RTN): all three cables must be connected in daisy-
chain configuration. The chain connection can be made without distinction by using the RJ45 connector couples (21) (one for in and one for out) or the
terminal block (20).The last inverter in the daisy chain must be “terminated” or the 120 Ohm communication line termination resistance must be activated
by switching the dip-switch (22).

Using the alarm terminal block
Terminal block (19) connecting to the configurable relay that allows connection of
external devices which, according to the mode selected in the menu “SETTINGS
> Alarm” can, for example, signal malfunctions. The operating modes that can
be set are: Production, Alarm, Alarm (Configurable) and Crepuscolar.
ATTENTION –AThe ALARM contact can be used only with systems that
ensure a safety isolating additional at least (supplementary insulation in
relation to the DC input voltage)
Using the REM terminal block
The REM terminal block (20), if suitably configured, allows the “Remote ON/
OFF” function to be used: this function allows remote disconnection of the
inverter from the grid
READ THE MANUAL –EFor further information regarding the configuration
and use of the communication and control signals terminal block, please see
the manual
12. Commissioning
The inverter commissioning procedure is as follows:
- Switch the integrated switch (08) (versions –S and –FS) to the ON position or close the external switches: If the input voltage applied to one of the two input
channels is greater than the minimum starting voltage, the inverter will start up.
- When the inverter is turned on for the rst time you will be asked to select the “Country” of installation. This selection allows the inverter to automatically
congure its parameters to ensure that compliance with local standards; the default language corresponding to the selected “Country” will also be set.
WARNING –BWarning! After the grid standard was set you have 24 hours to make any changes to the grid standard value; 24 hours later the
“Country Select.” functionality will be blocked, and any subsequent changes can only be made using a password provided on request by FIMER
After you have set the “Country” value, the message “Inizializing...Please Wait” is displayed. Depending on the input voltage value, the inverter will show
various messages on the display and change the behaviour of the three LED (04):
INPUT VO LTAGE DISPLAY MESSAGE LED STATUS DESCRIPTION
Vin < Vstart Waiting Sun
Green = FLASHING
Yellow = OFF
Red = OFF
The input voltage is not sufficient to permit
connection to the grid.
Vin > Vstart Missing Grid
Green = FLASHING
Yellow = ON
Red = OFF
There is sufficient input voltage to permit
connection to the grid: the inverter waits until
there is grid voltage to carry out the parallel
connection.
The inverter is powered ONLY by the voltage coming from the photovoltaic generator: presence of grid voltage alone IS NOT SUFFICIENT to permit the
inverter to start up.
With the inverter in “Missing Grid” status, close the AC switch downstream the inverter so as to supply the grid voltage to the inverter: the inverter performs
the grid voltage check, measures the photovoltaic generator insulation resistance against earth and carries out other self-diagnosis checks. During the
checks before the parallel with the grid, the green LED keeps flashing, the others are off.
During the grid voltage check and measurement of the insulation resistance, the values for the grid voltage and frequency and the insulation resistance
measured by the inverter are shown on the display. The inverter completes parallel connection with the grid SOLELY if the grid parameters meet the
ranges provided for by the regulations in force and if the insulation resistance is greater than 1Mohm.
If the preliminary checks for parallel connection to the grid are successful, the inverter connects to the grid and begins to export power to the grid. At this
stage, the display shows the inverter’s parameters in cycles. The green LED stays lit whereas the others are off.
13. Instruments
