2 Introduction
With this device you have acquired a inverter for connection of a photovoltaic system to the grid.
This inverter is characterized by an advanced housing design and state-of-the-art high-frequency
technology, which enable the highest levels of efciency and longest life.
The inverter includes key features and capabilities, such as anti-islanding protection, LCD, RS485
interfaces.
The inverter is usable indoors and outdoors. It fullls the directives of ANSI/NFPA 70, NEC 690.5,
UL 1741, IEEE 1547 and IEEE 1547.1 for parallel operation of power generation plants on lowvoltage network of regional electrical utility companies.
The function of the anti-islanding protection (automatic isolation point for in-plant generation sys-
tems) complies with UL 1741 / IEEE 1547 specications.
In the following technical description, the precise functions are explained to the installer, as well as
the user, which are required for the installation, operational start-up and handling of the inverter.
2.1 System
Renewable energy use worldwide is increasing annually by approximately 25%. The reason for
this rise can be primarily attributed to the constantly increasing demand for power, the increasing
interest in environmentally friendly technologies, as well as the increasing costs of non-renewable
energy.
Use of renewable energy sources, can reduce levels of CO
sphere produced by conventional power generation.
and other harmful gases in the atmo-
2
The inverter converts direct current from solar array into alternating current. This enables you to
feed your self-produced solar energy into the electric grid.
Thanks to efcient MPP tracking, maximum capacity utilization of the solar energy plant is ensured even in cases of misty and cloudy skies.
The string concept means that PV modules are always connected in series (in a string) and/or that
strings with the same voltage are connected in parallel to the inverter with the aim of signicantly
reducing the photovoltaic system’s cabling requirements.
The fact that the modules are connected in strings also means that the photovoltaic system can be
perfectly matched to the inverter’s input voltage range.
The inverter is transformerless, without galvanic isolation. Therefore, the inverter may only be oper-
ated with ungrounded PV arrays. Furthermore, the PV array must be installed in accordance with
the NEC690.35 (Ungrounded Photovoltaic Power Systems) and the locally valid regulations for
ungrounded PV arrays. Additionally, the PV array (PV modules and cabling) must have protective
insulation and the PV modules used must be suitable for use with this inverter. PV modules with
a high capacity to ground may only be used if their coupling capacity does not excessed 1,200 nF
with 60Hz grid.
8
2.2 Data evaluation and communication
The integrated data display, processing and communication of the device enables easy operation of
the inverter. Monitoring of the operational status and signaling of operational failures are capable of
being reviewed on the device display. The data interfaces enable the downloading of data.
The best way of accessing this functionality is via a monitoring system, such as SolrenView, connected to your inverter.
The read-out of the data on the display is possible when the inverter is connected to AC.
2.3 Technical structure of the inverter
The photovoltaic voltage is adjusted so that the maximum power output of the PV modules is also
achieved with different solar irradiation levels and temperatures (MPP-Tracking). These inverters
have quite wide MPP range of suit for variety of PV modules by a variety of manufacturers. Measures must be taken to ensure that the maximum no- load voltage of 600 V is never exceeded.
Please note that the maximum no-load voltage will occur at the lowest temperatures anticipated.
You will nd more detailed information about temperature dependency in the data sheet for the
PV modules. The device’s power consumption is kept to a minimum (1.5 W). Warranty is void if
600VDC is exceeded.
The high-quality aluminum casing corresponds to protection degree NEMA 4 / IP65 (water-jet proof
and dust-proof) and is protected by an anti-corrosion nish. The heat sink on the PVI 3800-7600TL
inverters is designed in such a way that operation of the inverter is possible at ambient tempera-
tures from -13°F to +122°F (-25°C to +50°C) at full rated power and optimal efciency for either 240
Vac or 208 Vac AC grids.
Aluminum ns designed into the back of the inverter chassis are used to dissipate heat and protect
the unit. An internal temperature control protects the interior of the device. In case of high ambient
temperatures, the maximum power is limited.
The inverter is controlled by microcontrollers which provide interface communication and the values
and messages on the front-panel display.
AC grid monitoring is done by an independent dedicated micro controller set up to meet the requirements of UL 1741 / IEEE 1547. This enables a connection of the inverter to the grid.
Operator protection requirements are met by electrically isolating the grid from the PV module. The
electrical isolation between the grid and the PV array is equivalent to basic insulation. Maximum
operator protection is ensured by reinforced isolation between the grid, PV modules and accessible
interfaces (display, RS485 interface and fan port). Relevant standards concerning electromagnetic
compatibility (EMC) and safety are fullled.
The inverter can only function as a grid-tied device. Anti-islanding function, which was certied ac-
cording to UL 1741, guarantees disconnection in case of loss of AC grid.
9
2.4 Ambient temperature
The inverter can be operated in ambient temperatures between -13°F to 158°F (-25°C to +70°C).
The following diagram illustrates how the power of the inverter is reduced automatically depending
on ambient temperature.
The device should be installed in a well-ventilated, cool and dry location.

4.5 Lightning and surge protection
Solectria PVI inverters are designed and certied to meet stringent UL 1741 / IEEE 1547 and
ANSI/ IEEE 62.41/62.42 AC lighting and surge requirements; however, every PV installation is
unique, thus additional external UL/NEC AC and DC surge protection and solid grounding practice
are recommended
4.6 Multiple inverters
Multiple Solectria PVI inverters are permitted at a common location if all applicable NEC, state,
local building codes and local utility commissioning guidelines are met. In addition, each inverter
should have its own dedicated AC branch protection circuit breaker and a dedicated PV string/
array, not to exceed the inverter’s ratings.
4.7 PV string considerations
There are a large number of PV module string combinations that will offer optimal performance
from either the PVI 3800TL, PVI 5200TL, PVI 6600TL and PVI 7600TL inverters due to its wide
MPP DC voltage range (200 V – 500 V).

DANGER!
DANGER!
WARNING!
AVERTISSEMENT!
CAUTION!
PRUDENCE!
To ensure maximum protection against hazardous contact voltages
while assembling photovoltaic installations, both the positive and
the negative leads must be strictly isolated electrically from the
protective ground potential (PE). All string fuses must be removed
from wiring box.
– Risk of electric shock and re. Use only with PV modules with
a maximum system voltage of rating of 600V or Higher.
– Electric shock hazard. The DC conductors of this photovoltaic
system are ungrounded and may be energized.
– Electric shock hazard. The DC conductors of this photovoltaic
system are ungrounded but will become intermittently
grounded without indication when the inverter measures
the PV array isolation.
– Verify all DC conductor voltages and polarities with volt meter
because damage to the inverter could result if incorrect DC
input voltage or polarity is connected. After verication of
correct voltage and polarity, DC fuses can be installed. NOTE:
array VOC at extreme cold ambient temperature must be veri
ed by calculation never to exceed 600 VDC.

4.8.5.1 PV string fuse information and calculating string fuse size
The PVI 3800TL, PVI 5200TL, PVI 6600TL, and PVI 7600TL inverters are shipped with 3 X 15 A
600Vdc Littlefuse KLKD 15 string fuses. The provided string fuses may or may not be appropriate
for your particular installation. Proper sizing of overcurrent protection is based on the maximum
short circuit current Isc (module) and calculated in accordance with NEC Article 690 requirements.
NOTICE!
AVIS!
WARNING!
AVERTISSEMENT!
The maximum acceptable string fuse for the PVI Inverter is 20 A
(KLKD 20). Use of larger fuses will void the warranty.
The string fuse rating should never exceed the Maximum Series
Fuse Rating provided by the module manufacturer. This value is
typically listed on the module label.
4.8.5.1.1 Calculating the minimum string fuse per NEC Article 690
The minimum string fuse size is calculated by multiplying the module Isc x 1.56.
Thus, if we are using modules that have an Isc = 6.25 A, we would calculate our minimum string
fuse size as follows:
String Fuse (minimum) = 6.25 A x 1.56 = 9.75 A
Reviewing our Littelfuse KLKD series fuses, we nd that 10 A is the next available fuse size. Thus,
to satisfy the minimum string fuse requirements per NEC Article 690, we would remove the 15 A
fuses shipped with the inverter and replace them with 10 A fuses.
A partial listing of the Littelfuse KLKD Fuses is as shown.
Part Number Amperage
KLK D 008. ............................ 8 A
KLK D 009. ............................ 9 A
KLK D 010. ............................ 10 A
KLK D 012. ............................ 12 A
KLK D 015. ............................ 15 A
KLK D 020. ............................ 20 A
33
It is worth noting that for this example we calculated the minimum series fuse rating. However, it
may be appropriate to use the supplied 15 A fuses insofar as they do not exceed the maximum series fuse rating (provided by the module manufacturer) or the overcurrent protection requirements
of your PV source wires. Please reference the appropriate NEC Article(s) for further discussion
regarding proper sizing of overcurrent protection
4.8.5.1.2 Generic fuse properties
Other fuse manufacturers may have compatible fuse types. The generic properties are:
• Fast-acting
• Dimensions: 1 1/2” in length x 13/32” fuse diameter
• Interrupt Rating: >= 10 kA @ 600 Vdc
• UL and CSA approval of the fuse is mandatory
• String fuses can be sized from 1 A to max. 20 A and rated for 600 Vdc. Please see above
sec. 4.9.8.1.1 for calculating string fuse size.
4.8.5.2 String fuse replacement
WARNING!
AVERTISSEMENT!
Ensure no live voltages are present on PV input and AC output
circuits, and verify that the DC disconnect, AC disconnect, and dedicated AC branch circuit breaker are in the “OFF” position, before
inverter installation.
DANGER!
DANGER!
PV solar arrays produce hazardous voltages and currents when
exposed to light which can create an electrical shock hazard. Using
dark opaque sheets, cover the PV solar array before wiring or
connecting cable terminations.

Note: Refer to Figure 31 for String Fuse Locations.
1. Gripping only the plastic tab on top of the fuse extractor, pull straight upwards without
touching the fuse’s metal end caps or fuse-holder clips on printed circuit board.
2. Away from open wiring box compartment, open the fuse extractor door and tilt fuse
extractor downward with a hand underneath to catch fuse as it slides out of fuse extractor.
3. Next place the replacement fuse into fuse extractor and tilt upward to keep fuse from
dropping out. Close the fuse extractor door.
4. With fuse/fuse extractor parallel to empty fuse position, lower fuse extractor while aligning
fuse caps with open fuse clips. Then push downward until the fuse snaps into the clips.
Follow the same procedure for replacing string fuses.

7.4.1 Shading
Description
The “Shading“ option is an extended MPP tracker. When the option is switched on, the MPP
tracker performs an additional search at regular intervals.
The MPP tracker then searches for the maximum power over a wider voltage range.
This option should be switched on if shadows regularly pass slowly over the PV modules in
the course of a day. These types of moving shadows can be caused by chimneys or trees, for
example. This option has a relatively small effect in the case of fast-moving shadows, e.g., from
passing clouds.
The option is set depending on the size of the shading.

Note: When in failure mode, the inverter will not produce power.
8.1.2Factorsinuencingtheoperatingstate
Different inuencing factors are assigned to the individual operating states. These inuencing
factors are divided into the following categories.
Associatedinuencing
factors
No factors are present that
inuence the production results.
Non-critical factors that can
affect the production results
but which are not failures (e.g.,
self-test).
External events or internal
failures are present that affect
the production results.
Problems exist with insulationNo
Grid feed-in
Yes
Different
Yes
Non-critical factors
Non-critical factors are (for example) the self-test or a DC voltage that is too low due to bad weather. Non-critical factors are therefore not failures.
Events
Events are usually caused outside the inverter. Events are divided into external events (e.g., voltage or frequency errors) and parameter changes occurring via the keys or the RS485 interface.
Internal failures
Internal failures are caused from within the inverter and must be corrected with help of the Solectria Support T eam.
59
Insulation and grounding failures
Insulation and grounding failures are logged and displayed when this failure occurs.
8.1.3 Display of the current operating state
The actual operating state is indicated via LEDs. A short message is also shown in the fourth line

The PV generator is divided up into individual strings which feed into the grid over their own string
inverters in each case. In this way, the installation is considerably facilitated and the gain decrease,
which can arise from the installation or from different shading conditions of the PV modules, is
considerably reduced.
