1.4 Circuit Structure Design

The basic schematic diagram of PVI 50/60TL inverter is shown in Figure 1.2. The input
of PV modules passes through surge protection circuitry, DC EMI wave filter, and the
front-end boost circuitry to achieve maximum power tracking and boost up voltages.
The output of the inverter converts the DC voltage to 3-phase AC voltage. The high
frequency AC components are removed with a wave filter. The 3-phase AC voltage is
then passed through two-stage relays and EMI wave filter to produce high quality AC
power.

1.6 Anti-Islanding

This inverter includes active Anti-Islanding detection as required by
UL1741/IEEE1547. The inverter will automatically make small variations in reactive
power output in order to detect a possible islanding condition. If the grid is stable,

PVI 50/60 TL Installation and Operation Manual (Rev C)

DOCR-070645-E Page 13 of 102

these small variations will have negligible effects on system voltage and frequency.
However, in an islanded condition the small amount of reactive power changes will
force the system voltage or frequency to change significantly, which will trigger the
inverter to shut down. This function is always on and cannot be turned off by the
user.

1.7 DC Ground Fault Protection

The PVI 50/60TL includes residual current detection as part of the DC ground fault
detection method as required by UL1741. If there is a ground fault in the array, the
ground fault detection technology will detect the array leakage current. The
inverter will shut down if the leakage current exceeds 500mA.

1.8 Surge Suppression

 Standard 1.2/50 μs - 8/20 μs Combination Wave
 Standard 0.5 μs - 100 kHz Ring Wave

1.9 DC Arc Fault Detection

The PVI 50-60TL includes DC arc fault detection compliant with UL 1699B. The
inverter detects electrical noise that typically accompanies a DC series arc. The
inverter will shut down should the arc fault sensor detect a series arc.

The PVI 50/60TL inverters are equipped with standard 15A DC fuses. Customers must
verify that the appropriate fuses are installed depending on the PV system design.

(a) Each independent PV DC input string needs fuse protection.
(b) The rated voltage of fuses should be 1000V
(c) The rated current of fuses is generally 1.56 × short circuit current from the PV

strings, rounded up to the next available fuse size.

The following table lists the fuse type, specifications and number under the rated
voltage and power range of 10 strings of PV panels.

Table 2.7 - DC Fuse Selection

NOTE 1: The 1000VDC Littelfuse fuse series is recommended. Detailed information

is available at: http://www.littelfuse.com/.
NOTE 2: The fuse holders can also accept a 20A (SPF020), 25A (SPF025) and a 30A
(SPF030) fuse for combined input strings if needed.

NOTE 3: Two 30A fuses should not be used next to each other.
NOTE 4: If string fuses other than the provided 15A fuses are desired, it is the
customers’ responsibility to source and install these extra fuses.

WARNING:

Use of different fuses or wrongly sized fuses can cause damage to
equipment or create un-safe working conditions. Any damage resulting
from incompatible fuses is not covered by warranty.

3) DC Conductors Connections

To ensure the optimum performance of the inverter, please read the following
guidelines before making DC connections:

(a) Confirm the DC configuration referring to Table 2.6 and ensure that the

maximum open circuit voltage of the PV modules is lower than 1000 VDC
under any conditions.

(b) Confirm that the PV strings for each MPPT of the inverter are of the same

module type, power level and string length before connection. The number,
orientation, and tilt of PV strings may differ for different applications.

(c) Configure the external wiring according to the conditions in Table 2.8.

WARNING:

Working with live voltage is dangerous. It is recommended to have all
live circuits disabled prior to performing connections.

Table 2.8 - DC Input Configuration

*Note that the provided fuse is 15A, your string combination may require a

larger rated fuse. Always verify the Isc rating of the input prior to connecting
to the fuse holder.

**Mixed input signifies a combination of fuse holder connections and fuse

bypass terminal utilization. Such combinations are very rare, but possible.
The wire size for the fuse holder connection is #10-8 AWG (30 in-lbs) and up
to #2 AWG for the bypass terminal (50 in-lbs).

NOTE: The temperature rating of the input wiring should be 90℃ or greater.

Figure 2.32 - Three MPPTs Operating Independently

Independent mode can be very useful for sites with shading on parts of the array
or with arrays consisting of different orientations. However, this also means that

one must consider these three zones as three separate inverters and power must
be balanced as much as possible between the three MPPT zones. See Table 2.8
for string/zones combinations.

NOTE: Always try connecting an equal number of wires to PV1, PV2 and
PV3 to each individual MPPT zone.

PVI 50/60 TL Installation and Operation Manual (Rev C)

DOCR-070645-E Page 40 of 102

NOTE: Connecting all of the inputs at zone “PV1” will result in only
utilizing 33% of the inverter power

2.3.2 AC and Ground Connections

The following describes how to connect the AC and ground conductors between the
inverter and the AC grid:

1) Use a #3 Phillips head screwdriver to loosen the 4 screws on the wiring box

and remove the cover. (see Figure 2.33)

2) Remove the knockout plugs from the holes of the AC side and install the

suitable conduits of 1-1/4 inch through the holes. Then pull the cables

through the conduit into the wiring box.

3) The inverter supports 3 kinds of conductor connection on the AC side

depending on the grounding connection method. The conductor set-up

procedures are illustrated below.

Use Tables 2.10 and 2.11 for required tools and torque values

Figure 2.33 - Remove the Wiring Box Cover

Table 2.10 - Required Tools

WARNING:

Strings must be balanced for optimum performance and AC output. When
doing DC/AC ratio sizing, perform calculations at the zone level. Maximum
DC/AC oversizing ratio is 1.5 STC conditions of the modules. Each zone
maximum input power is 25kW (50TL) and 30kW (60TL). Note for any
application that may experience higher than 1000 W per m2 on a regular
basis, a smaller DC/AC ratio is recommended. Also, the combined Isc rating
of all strings multiplied by 1.25 must be less than 60A for Individual mode.
Failure to follow those guidelines will result in damage to the inverter
which is not covered under the warranty.

NOTE: If you are using aluminum wires you need to follow the following steps to prep
each cable prior to connecting to the AC terminal block:

a) Using a utility knife, gently strip the top layer of the aluminum conductors

Figure 2-38 Preparing aluminum wires prior to connecting

b) After removing the oxidized layer immediately apply neutral grease (Noalox or acid­and alkali-free Vaseline) and connect the cable immediately to the terminal. Perform
one cable at a time. If you need to stop the process before applying the grease, and
continue later- you will need to scrape it again. It takes 30-60 seconds for an oxidized
layer to form on top of the conductors.

Acceptable transformer configurations:

PVI 50/60 TL Installation and Operation Manual (Rev C)

DOCR-070645-E Page 45 of 102

Table 2.13 – Transformer configurations

When interfacing with a Wye-grounded transformer winding, a neutral is required.
Since the neutral is used by the inverter for voltage sensing only, the neutral does not
carry current. The size of the neutral may be reduced to a conductor no smaller than
the EGC or 8 AWG, which is the smallest acceptable wire for the terminal block. Note
that if AHJ approves, you can install a jumper across the EGC and the Neutral terminal,
this will satisfy the inverter sensing purposes.

When installing multiple inverters for parallel operation connected to a single
transformer winding, the kVA rating of the transformer must be at least 5% greater
than the total connected inverters’ kVA rating. Up to 50 inverters may be connected in
parallel for use with a single transformer.

2.4 Inverter Communication Connections

The PVI 50/60TL inverter supports industry standard Modbus RS485 communications
for monitoring purposes. In addition to SolrenView and/or third party monitoring,
these inverters are also able to send data to an online portal which is used for
remote diagnostic purposes. This capability can be used by Yaskawa-Solectria Solar
for remote diagnostics, remote firmware upgrades and remote troubleshooting.
This function is performed by the Ethernet Network Card.
Each Ethernet Network Card can handle up to 32 inverters. If a site has more than 32
inverters, additional Ethernet Network Cards will be needed.
When a third party monitoring system is used, the DAS should be connected to the
Ethernet Network Card, and the Ethernet Network Card is then connected to the
inverters.
Each inverter has a Communication Board installed in the wiring box which is used to
daisy chain the inverters using RS485 for communication purposes. The Ethernet
Network Card should be mounted on the communications card of the first or last
inverter in the daisy chain.
The following sections describe an overview of the Communication Board and
Ethernet Network Card.

2.4.1 Communication Board:

Each inverter has a Communication Board (shown below) which is installed in the top
right corner of the wiring box. This board is used for daisy chaining inverters for
connection to the Ethernet Network Card.

2.4.2 Ethernet Network Card:

A maximum of 32 inverters can be connected to this device. When provided with an
internet connection, it can send data to an online portal which Solectria can use for
troubleshooting and remote diagnostic purposes. It is also used for allowing the
connection of a 3rd party monitoring system.
Customers are required to provide internet to the Ethernet Network Card in order
for it to be used for remote diagnostic purposes. Once connected, Solectria can
remotely check inverter parameters (currents, voltages, parameter settings, etc.) and
alarm messages. Solectria can also use this device to remotely update firmware on
all the inverters connected to it.

External DAS, connectors and termination resistance details

 When connected to an external DAS, Solectria PVI 50/60TL inverters support up to 32

inverters/devices on the RS485 daisy chain. The Inverter Modbus IDs are configurable
from 1 to 128.

 Yaskawa - Solectria Solar recommends limiting the RS485 daisy chain for PVI 50/60TL

inverters to a maximum length of 3000 ft. (914m). Additionally, no individual run should
be longer than 300 ft. (91.4m).

 Care must be taken when daisy chaining the inverters, utilizing a shielded twisted pair

cable such as Belden 9841 or Southwire 58165802.

 The shield continuity should be maintained for the entire length of the daisy chain and

should only be connected to ground (GND) at the DAS. The shield should not be
connected to any of the inverters to prevent any possible grounding loops.

 It is important to terminate the Modbus (RS485) daisy chain correctly to minimize any

bus noise and reflections. The daisy chain should be terminated at the source (the DAS)
and at the last Modbus device in the daisy chain. The PVI 50-60TL Modbus termination
resistor is turned on by flipping switch S1 to the ON position as shown in Figure 2-45. S1
should always be left in the off position except for the last inverter in the daisy chain.

 Non-serial, such as star or ring, network topologies should always be avoided.

4.2 Operation State

Table 4.1 describes the meaning of LED indicators (i.e. it indicates the inverter’s
operational state).

 “POWER” will light up to indicate that the system is energized and

under DSP control.

 “RUN” will light up when the inverter detects that the grid connection

conditions meet the requirements and power is fed into the grid. “RUN”
will blink if the grid is in de-rated running state during the period of
feeding power into the grid.

 “GRID” will light up when the grid is normal during the operation of the

inverter. Otherwise, “GRID” will blink until the grid restores to normal.

 “FAULT” will blink quickly as a fault (except grid fault) occurs. “FAULT”

will not turn off until the fault is eliminated. The light will blink slowly
when an alarm occurs. “FAULT” remains illuminated when an internal
fault occurs. The buzzer will give an alarm if a fault (involving power
grid fault) occurs.

(2) “Factory Default” menu: The manufacturer’s default parameters value can be
restored when the inverter is not in operation mode. If you try to change the
parameters while the unit is operational “Fault Operated” will be displayed.
(3) “Auto Test” menu: Used for factory test only. Not intended to be used by the
user.
(4) “MPPT Scan” menu: “MPPTScan” is to execute the MPPT scanning manually.
Move the cursor to this item, and press ENT to initiate the scanning. The LCD screen
will skip to normal operation interface if the MPPT scanning succeeds, or remain on
the “MPPTScan menu” interface if the scanning fails.
MPPT scan function is used for multi-MPP point tracking, if the PV panels are partly
shadowed or installed with different angle. The factory default setting of MPPT scan
is Enabled, and it can also be Disabled. When the MPPT scan function is enabled, the
scan period is 60 minutes; the inverter will scan the maximum power point in the

MPPT range, according to below condition：

In independent mode, each input power is lower than 75% of the rated power
of each MPPT tracker.
Once this MPPT scan function is activated thru the LCD, it will search the
maximum power point at a voltage step of 5V in the MPPT range for full load,

and get the maximum power point.
(5) “ARC Detect” In the “Parameters Setting””Control Command” menu, execute
the “ARC Detect”, the inverter will stop working and test ARC.
Arcing check and protection is mainly divided into two parts, the Arcing check board
is responsible for detecting if there is arcing in the PV line, and sends the arcing
protection signal to the DSP in the control board. The control board “DSP” is
responsible for turning the inverter off the grid after receiving the arcing signal to
ensure safety. The arcing board failure will cause ‘arc board err’ shown on the LCD
and it will not connect to the grid until the arc board is OK. If there is Arcing fault, the
LCD displays the fault which can only be cleared manually.
(6) “ARC Clear” is used to clear the ARC fault. Move the cursor to this menu, and
press ENT. The operation result will appear on the LCD, ie. “Succeed” or “Failed”.

5.0: Operation

5.1 Start-Up

Manual Start-up: Manual start-up is required after regulation setting change or

manual (fault) shut-down. Move the cursor from the main operation interface
to “Setting”. Press ENT and go to submenu “1 ON/OFF”. Then move the cursor to “ON”
and press ENT to start the inverter. The inverter will start up and operate normally if
the start-up conditions are met. Otherwise, the inverter will go to stand-by mode.

Automatic Start-up: The inverter will start up automatically when the output voltage
and power from the PV arrays meet the required values, AC power grid is normal, and
the ambient temperature is within allowable operating range.

5.2 Shutdown

Manual Shutdown: Normally, it is not necessary to shut down the inverter, but it can

be shut down manually if regulation setting or maintenance is required.

Move the cursor from the main operation interface to “4 Setting”. Press ENT and go to
submenu “1 ON/OFF”. Move the cursor to “OFF” and press ENT, and then the inverter

will shut down.

Automatic Shutdown: The inverter will be shut down automatically when the output
voltage and power of PV modules are lower than the required values, AC power grid
fails, or the ambient temperature exceeds the normal range.

5.3 Operation Mode

There are 4 operation modes. The following are corresponding indications for each

In this mode, the inverter converts the power generated by PV modules to AC
continuously and feeds into the power grid.

(3) Standby mode, as shown in Figure 5.3:

The inverter will enter standby mode when the output voltage and power of PV
modules do not meet the startup conditions or PV voltage and input power are lower
than the set values. The inverter will check automatically whether it meets the startup
conditions in this mode until it turns back to normal mode. The inverter will switch
from standby mode to fault mode if a malfunction occurs.

5.4 Grid-Tied Power Generation

PVI 50/60TL series inverter has an automatic grid-tied power generation process. It
will check whether AC power grid meets the conditions for grid-tied power generation
constantly and test whether the PV array has enough energy. After all conditions are
met, the inverter will enter grid-tied power generation mode. While in the grid-tied
power generation mode, the inverter can detect the power grid at all times, and also
keep the photovoltaic array output in maximum power point tracking (MPPT) mode.
In case of any abnormity, the inverter will enter the protection program immediately.
In low light conditions when the PV power is not enough to keep the inverter in
operation, the inverter will enter standby mode. When the voltage of the PV array
changes and becomes stable and higher than the required set value, the inverter will
attempt to start grid-tied power generation again.

WARNING:

All installation and wiring connections should be performed by qualified
technical personnel. Disconnect the inverter from PV modules and the AC
supply before performing maintenance.
Do not work on the inverter until at least 5 minutes after disconnecting
all sources of DC and AC.

Toutes les installations et les connexions de câblage doivent être
effectuées uniquement par le personnel technique qualifié.
Débrancher l'onduleur de modules photovoltaiques et le grid électrique
avant l'entretien et la marche de l'équipement.
Ne pas utiliser ou entretenir l'onduleur jusqu'à au moins 5 minutes après
avoir débranché toutes les sources du côté C.C. et C.A.
