by passing the cable through the DC cableglands (17). (FIG. 13).

- Confirm the DC cables have a 13-21mm diameter, a cross-section of

95mm² and are made of copper or aluminum.

- Unscrew the cable gland and remove the cap

- Run the cable through the cable gland (17)

- Connect the PV array (+ and -) to the DC input screw terminal block (39)

(tightening torque 20 Nm) (FIG. 14)

-When finished, confirm the polarity is correct for each string.

- Pull each cable to check its tightness.

INPUT

OUTPUT AC

• PVS-50(60)-TL-SX and PVS-50(60)-TL-SX2 Models

In these inverter models, the PV array is connected to the inverter through

quick fit input connectors (MPTT) (19), (20), (21) located at the bottom of

the mechanics. (FIG. 15)

- Based on PV system configuration, inputs can be set as 3 independent

MPPTs or as a single MPPT with the three paralleled input channels.

Paralleled inputs can be obtained by installing the bar (provided) on

the paralleled MPPT connection points (41) using the 3 screws (M5x12,

tightening torque 4.0Nm) (FIG. 16) An incorrect setting of the input

channels can lead to loss of energy production.

- Quick fit connectors are divided into 3 groups (a group for each input

MPPT), each composed of 5 couples of quick fit connectors. Refer to

document "String inverters – Product manual appendix" available on

FIMER website https://www.fimer.com to find out the make and model

of the quick fit connector used on the inverter. Depending on the type

of quick fit connectors installed on your inverter, you will have to use

the same type for the corresponding counterparts (after checking for

compliant counterpart on the manufacturer's website or with FIMER).

WARNING –

The use of non-matching counterparts for the quick

fit connectors installed on the inverter may seriously damage the

inverter and invalidates the product warranty.

- Connect all strings to the appropriate

quick fit connectors (+ and -) following the

site wiring diagrams e check the tightness

of each Single connection. If some string

inputs are not used, ensure that caps are

installed on the connectors; install them if

missing. This operation is necessary for

the tightness of the inverter and to avoid

damaging the free connector that may be

used at a later date. (FIG. 17)

10. Instruments

Description of the LEDs located on the inverter cover:

POWER LED

GREEN On, if the inverter operates correctly.

Flashes in the network control phase or if the

sunlight is not enough.

ALARM LED

YELLOW The inverter has detected a fault. For

inverters with a display, the error/warning message

appears on the display.

GFI LED

RED Ground fault of the PV array, DC side. For

inverters with a display, the error message appears

on the display.

11. Commissioning

ATTENTION –

Before

procedure, ensure that all the checks indicated in the previous

sections of this Quick Installation Guide have been correctly

performed and also that the front door 4 have been correctly

closed! Make sure irradiation is stable and adequate for the inverter

commissioning procedure to be completed.

Commissioning could be carried out in two different ways:

• Via "Installer for Solar Inverters" mobile APP - Recommended

mobile APP for commissioning single inverter as well as multi

inverter solar plant.

• Via Web UI (access point wireless network) - Integrated Web User

Interface enabling setting parameters and performing commissioning of a

single inverter (multi inverter support is not provided). Recommended as

alternative method for performing single inverter commissioning.

Commisioning via "Installer for solar inverters" mobile app

"Installer for Solar Inverters" is the new advanced FIMER mobile APP

allows to simplify commissioning, parameter settings and troubleshooting

of FIMER string multi-inverters in large scale solar plants.

Even in case of single inverter installation it can be consider the most

suitable professional tool to be used. "Installer for Solar Inverters" mobile

APP is available for mobile devices with an Android version of 6.0.1

or greather (iOS mobile devices support will come soon) and could be

downloaded and installed from Play Store.

Commissioning procedure:

• It's highly recommended to connect the inverters in ethernet daisy chain

(with or without ring) before executing the commissioning procedure.

Make sure that all the inverter being commissioned features the last

firmware version (updating can be executed via Installer for Solar

Inverters mobile APP).

• Supply the input voltage from the photovoltaic generator to the inverter.

ATTENTION –

Make sure irradiation is stable and adequate for the

inverter commissioning procedure to be completed.

The main steps to complete the commissioning procedures are

listed below:

• Installer for Solar Inverters mobile APP installed on mobile device.

• Enabled Aurora Vision installer account allowed to use the mobile APP.

The account can be created in the mobile APP directly following the

dedicated wizard procedure.

• Manual

claiming

the

The claiming process consists of indicating which inverters are to be

commisioned.

Claiming process can be executed by scanning the QR codes of all the

inverters being worked and putting the selected inverters into the working

list. Please insert in the list inverters belonging to the same inverters

family; no more than 40 inverters by time can be configured together.
