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,
DOCR-070645-A
Page 12 of 104
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.

1.9 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.

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
DOCR-070645-A
Page 30 of 104
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 2.5 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 2.6.
WARNING:
Working with live voltage is dangerous. It is recommended to have all
live circuits disabled prior to performing connections.

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.
(d) Check the polarity of each PV string pair (Figure 2.20) before connecting to
the DC fuses or fuse bypass points by following these steps:
i. Using a multi-meter: connect the positive lead from the multi-meter to the
positive lead from the string and the negative lead from the multi-meter to
the negative lead from the string. If the value on the multi-meter is
positive, the polarity of the strings is correct.
ii. The positive (+) end of the PV string conductor should match the positive (+)
terminal of inverter’s DC input.
iii. The negative (-) end of the PV string conductor should match the negative (-)
terminal of inverter’s DC input.
NOTICE:
It is important to use a multi-meter to check the polarity of the DC input
cables to avoid any risk of reverse polarity.
Il est important d'utiliser un multimètre pour vérifier la polarité des
câbles d'entrée C.C. pour éviter tout risque d'inversion de polarité.

(e) Remove the plug from the DC conduit knockout holes and install the suitable
1.5 inch conduits via the knockouts. Then pull the cables through the
DOCR-070645-A

conduits into the wiring box.
(f) Connect the DC cables to the fuse holders and fasten the screws, as shown in
Figure 2.21: Note: If you are using the fuse bypass- skip this step
Tools: #2 Phillips bit and a Torque driver.
Torque value: 3.4N-m (30 in-lbs)
NOTE: If the installer does not use a torque driver to secure the conductors
there is risk of potential damage to the equipment, which is not covered by
the warranty.

Figure 2.23 - 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 2.6
for string/zones combinations.
DOCR-070645-A
Page 34 of 104
NOTE: Always try connecting an equal number of wires to PV1, PV2 and
PV3 for individual MPPT zone operation.
NOTE: Connecting all of the inputs at zone “PV1” will result in only
utilizing 33% of the inverter power
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
2
application that may experience higher than 1000 W per m 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 50A per MPPT for (50TL)
and 60A for (60TL) for Individual mode. Failure to follow those guidelines
will result in damage to the inverter which is not covered under the
warranty.
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 2.24)
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 2.7 and 2.8 for required tools and torque values

Page 37 of 104
NOTE: If you need a larger AC conduit hole, punch one by removing the AC output
adaptor plate and following the steps from Section 3: “DC Input Cable Connection”.
(3) Connecting the inverter to the grid would require a breaker.
(4) The Grid connection type should be (L1, L2, L3, N, PE). A dedicated Neutral wire is
required for proper internal voltage balance.
Either a 3-pole or 4-pole AC circuit breaker should be selected as per the following
specifications. Choosing any other breaker size may result in nuisance tripping or
rejection from the AHJ.

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 2-27 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
DOCR-070645-A
Page 38 of 104
continue later- you need to scrape it again. It takes 30-60 seconds for an oxidized layer
to form on top of the conductors.

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.
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.

2.4.1 Third Party Monitoring Systems Modbus Connections
The PVI 50-60TL inverter can be connected to an external Data Acquisition System (DAS) via
an RS-485 shielded twisted pair serial connection as shown in Figure 2.30. They will
communicate with an external monitoring system via the standard Modbus RTU protocol.
Figure 2.30 - PVI 50-60TL Inverters in a RS-485 Daisy Chain Connected to an External
DAS

When connected to an external Data Acquisition System (DAS), Solectria PVI 50-60TL
inverters support up to 32 inverters/devices on the RS-485 daisy chain. The Inverter
Modbus IDs are configurable from 1 to 128.

Yaskawa - Solectria Solar recommends that the RS-485 daisy chain for PVI 50-60TL
inverters is limited to a maximum length of 3000 ft. (914m).

Care must be taken when daisy chaining the inverters as shown above, 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 Data Acquisition System (DAS). The
shield should not be connected to any of the inverters to prevent any possible ground
loops.

It is important to terminate the Modbus (RS-485) 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, typically an inverter. The PVI 50-60TL
Modbus termination resistor is turned on by flipping switch S1 to the ON position as
shown in Figure 2-28. S1 should always be left in the off position except for the last
inverter in the daisy chain.
DOCR-070645-A
Page 42 of 104

Star or T Modbus (RS-485) network topologies should always be avoided. See Figure
2.31.
Figure 2.31: Connecting External DAS Modbus (RS-485) Network to the PVI 50-60TL
Inverter
It is important to daisy chain the inverter RS-485 connections to minimize noise and
bus reflections. Any network topologies shown to the left should be avoided.
Equivalent daisy chain topologies shown to the right should be used instead.

Router/Firewall Configuration:
The router/firewall should not require any special configuration as most routers are already
configured to support DHCP discovery and to allow outgoing traffic. In case the router/firewall
is configured to restrict outgoing traffic, an outgoing rule must be added to allow the logger to
connect to the SolrenView Monitoring data servers.
2.4.2 Preparing the Inverter for Modbus Communications
To ensure correct Modbus communications with the SolrenView data logger, each inverter
Modbus communications settings need to be configured properly. Please follow the steps

2.4.3 Connecting Revenue Grade Meter
WARNING:
Risk of Electric Shock.
Make sure all DC and AC power has been disconnected before starting any work.
Some installations require Revenue Grade Metering (RGM) for accurate energy production
tracking and reporting. For that purpose the RGM needs to be connected to the SolrenView
Logger over Modbus (RS-485) connection as described below.
Figure 2.34 - This figure shows how the Veris RGM meter is connected to the Modbus
(RS-485). Note the 120 ohm Modbus termination resistor (not supplied) is only
needed if the RGM is the last device in Modbus daisy chain.
WARNING:
Risk of Electric Shock or equipment damage.
Make sure all shield wires are properly secured and insulated (i.e. heat shrink) to
prevent shorting to any other components inside the inverter.
The SolrenView data logger is configured to automatically search for and detect an RGM. No
special SolrenView data logger configuration is required for supported RGMs.
DOCR-070645-A

Snap the CT onto the conductor.
Connect CTs to the correspondingly colored voltage leads. If the application can
exceed 20 times the rated CT current, use wire ties to secure the I-bar to the CT
housing.
This CT automatically detects phase reversal, so CT load orientation is not
important.
Figure 2.37 - Use wire ties to secure the I-bar to the CT housing.
4.
5.
Connect the shielded twisted pair Modbus cable to the Modbus (RS-485) terminal
as shown in Figure 2.34. Only add a 120 ohm termination resistor if the RGM is the
last Modbus device in the Modbus daisy chain.
Do not connect the cable shield to the RGM.
Enable power for the RGM and the SolrenView Logger will automatically discover
the RGM when it is turned on.

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.

4.4.2.2 Control Command
There are 8 submenus in the “Control Command”:
(1) “Restart” menu: If a fault shutdown happens, a severe fault may have occurred
inside the inverter. The user can perform a manual reboot once using this menu if
the user needs to restart the inverter.
INSTRUCTION:
This function is effective only when the fault “IntFault0010~0150” in the
troubleshooting table occurs. The inverter may return to normal operation
DOCR-070645-A
Page 65 of 104
automatically if alarm or protection faults occur. This function will not
respond when the inverter is in operation mode and a “FaultOperated”
alarm interface is indicated.
(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”.
(7) “CEI Frq Enable” is used to enable/disable the CEI frequency control function.

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.
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.

Shade Cover
OPT-SHADECOVER-PVI-50-60TL is specifically designed for inverters mounted at a
15-degree tilt angle. It protects the inverter from harsh weather and direct
sunlight/extremely hot temperatures while reducing thermal gain on the inverter
and increasing energy production.
PVEL, now part of BEW/DNV Kema, performed field testing of the shade cover
temperature effects of the inverter case temperatures. The normalized data analysis
showed 2-15% less temperature rise on the inverter case temperatures. Front, Back
and Top temp rise was 6%, 4%, 15% lower with the shade cover (as shown in Table
8.1 on the next page).
