1. INTRODUCTION
Microinverters have become the preferred technology for installing solar PV solutions on residential roofs
today. Their inherent ability to address common challenges such as shade, rapid shutdown, system cost
reduction, and their easy installation, has made them the preferred residential inverter solution.
SPARQ Systems Inc. takes this concept even further with the Q2000, the first 4-port microinverter
optimized for residential applications and designed to meet current and future requirements. Through
our patented DC-to-AC conversion technology, we developed a design that supports four panels with all
the benefits of a single panel microinverter, such as eliminating high voltage DC wires on the roof while
reducing part count and install time. The result is a system that is cost- effective, easier to install, and
more reliable than other solutions on the market today.
Figure 1: Typical roof-top micro inverter home installation.
With its new generation Q2000 microinverter, SPARQ has considered the entire installer experience to
produce an optimum overall system design. With that in mind, we used ZigBee and WiFi networking
technology and a “mobile-first” approach, resulting in a fast and simple installation of the monitoring
gateway in the customer’s home. No longer will solar installers fight with intermittent powerline
communication solutions or move around the house to locate the device, and a simple smartphone or
tablet will provide all the interface needed to install a system. The Q2000 has the most advanced power
conversion design in the industry today. It is the first microinverter on the market with reactive power
capability, designed to meet the new interconnection, operation and metering requirements for
distributed generators to be connected to a utility’s electric system now. It does all of this without
sacrificing performance, having ultra-fast per-panel maximum power point tracking (MPPT) to optimize
production, with a peak MPPT efficiency of 99.85%.

1.1. What is a SPARQ Microinverter
The SPARQ Q2000 microinverter is a power conversion device that connects to up to four photovoltaic
(PV) modules and converts the DC output of the modules into grid-compliant AC power. PV systems that
use the SPARQ Q2000 microinverter produce an optimal energy harvest by employing proprietary
maximum power point tracking methods (MPPT), with the algorithm running for each of the four modules
individually. The SPARQ Q2000 is a ‘plug-and-play’ device and is auto-grid configurable worldwide, so it is
very easy and safe to install. For your safety, a Ground Fault Detection Interrupter (GFDI) is incorporated
to protect the system if a ground fault occurs during operation.
The SPARQ Q2000 microinverter is light, compact, and efficient relative to string or central inverter
systems. It is designed to have a functional lifetime matching or exceeding that of the photovoltaic
module. The result is high-quality power generation and excellent system availability. In addition, the
microinverter is very robust and delivers excellent performance even under adverse conditions such as
snow, dust, shade and low light.
1.2. System Configuration and Monitoring
The SPARQ Communication Gateway is called SparqLinq and uses a ZigBee wireless link to create a mesh
communication network with the Q2000 microinverter(s). SparqLinq gathers, processes, and stores
microinverter performance and status information internally and can display a system dashboard via its
own internal webserver. If it is connected to the internet through a WiFi or a wired Ethernet connection,
it automatically uploads performance information to the SPARQ cloud-based monitoring system, SparqVu
(http://sparqvu.com). All installers and home-owners are encouraged to create a SparqVu account.
Figure 2 depicts a typical wireless setup for monitoring, using the wireless-enabled SparqLinq model.
Figure 2: Power monitoring using wireless-enabled SparqLinq system.

Installation & Setup
SPARQ Q2000 Microinverter Installation Manual –Version 1.1, March 2023
Page 10
The SparqLinq internal web server and SparqVu cloud-based server enable an installer or system owner to
quickly view the performance of every component of their SPARQ energy system via a web browser on
their smart device or computer. SparqLinq achieves this detailed performance tracking by periodically
polling all microinverters with a typical polling cycle of fiveminutes.
A setup wizard walks the installer through the simple procedure of configuring the SparqLinq and
microinverter system. Once configured, the SparqLinq automatically collects data from each PV module
and reports it to SparqVu, allowing a detailed real-time view of performance information from any PV
module in the system. Information such as energy production, operational status, and power output can
be easily reviewed at a glance. The monitoring system keeps a database of historical performance data of
all the panels associated with a particular site. Information is presented graphically making it easy to
understand.
2. SPARQ MICROINVERTER INSTALLATION DESIGN
2.1. Preparation
Before installing Q2000 microinverters, ensure the following equipment is at hand, and the minimum
site requirements are met:
●Outdoor-rated AC junction box
●Phillips screwdriver
●Sockets, wrenches for mounting hardware
●Suitable racking system (for PV modules)
●Ti-Lane AC Branch cable and AC disconnect tool
●Ti-Lane DC disconnect tool (additional DC disconnect tool needed that
matches module connectors)
●Appropriate grounding conductor, or WEEB solution
●Grounding hardware is included with unit for copper cable
NOTE: 2 locking washers, 3/8” hexagonal nut, and 1 Phillips head bolt are included on each unit.
2.2. PV module and Microinverter Compatibility
SPARQ Q2000 microinverters are compatible with PV modules where the MPPT voltage range falls within
the microinverter model-specific voltage range. The microinverters are designed to work with a single-
phase 208V to 240V AC grid.
The electrical properties of the microinverters are summarized in the following table:

Installation & Setup
SPARQ Q2000 Microinverter Installation Manual –Version 1.1, March 2023
Page 11
To ensure that the PV module can be directly plugged into the microinverter, choose a module with
MC4 style or Ti-Lane T4 style compatible connector.
2.3. Module System Design Configuration with Templates
When installing and implementing a SPARQ Q2000 microinverter, there are five common arrangements
for the solar panels, with a version of each for portrait and landscape configurations. Using these basic
designs will simplify the design and planning for each installation.
In most designs with more than a single row of modules, the even row modules will be installed rotated
such that the junction boxes are at the bottom of the module. This is to ensure that the DC cables can
reach the microinverter DC inputs. Alternate configurations can easily be supported via extension cables.
SPARQ has created simpletemplates for each of these designs. In some cases, where the standard building
blocks are not applicable, an extender cable may be required to ensure easy connectivity to the Q2000
microinverter.
It is critical to note that the SPARQ Q2000 microinverter must be installed under the module,
and not exposed to direct rain or sunlight. Do not mount the microinverter in a position that allows long-
term exposure to direct sunlight or in a vertical orientation that allows water to pool by any of the
connectors. ALWAYS install the microinverter with the SPARQ Logo and grounding lug side up towards
the module to ensure proper heat dissipation.
2.3.1. Rectangle
The most common and easiest design for the Q2000 is simply called “The Rectangle”. The Rectangle
reflects four modules together in either a portrait or landscape layout. This configuration applies to the
most common deployments seen today, including:
• The rails are attached one-quarter of the way down the module frame, or about 16” or 400mm
from the top and the bottom of a typical 60-cell and 72-cell module frame.
• Junction boxes are usually near one end of the module frame, with the cables extending 40”
or 1m long.
• In some cases where the rails are attached further from the module end, the microinverter may
need to be attached to the other side of the rail, but in most cases the following design
guidelines will work, allowing the cabling to be routed cleanly.

Page 12
Often a residential design will have areas that do not fit so cleanly into the Rectangle pattern. To meet
these applications, one of the other common patterns may apply. For each of these, one or more pairs of
DC extender cables will be required.
2.3.2. Row of Four
The second most common configuration is four modules in a row, either portrait or landscape as shown
below. Some example installation techniques are given here, either can be reversed as desired. Knowing
this before arriving at the site will ensure easy cable and Q2000 layout.
Landscape layout
• When placing four in a row in landscape, allocate numbers to panels from right to left as follows: one
(1) two (2), three (3), and four (4). (See following diagram.)
• Connect modules 1 and 2 first and connect them to the racking. Then connect the module 4 but do not
tighten it, instead rest it in a temporary and stable position. Then connect the one under module 3
over the Q2000 and connect it to the rack. Last, place the module #4 in its permanent position,
tightening it last.
Figure 4: Q2000 –Row of four arrangement.
2.3.3. L-shape
Sometimes to make things fit in unusual configurations or to work around obstacles on the roof, an L-
Shape solution can be an effective option in either portrait or landscape mode as shown below:

2.4. Accessories
Extension Cables
As noted, sometimes a DC extension cable will be needed to reach the centrally located Q2000. These
are noted in the designs above. These DC extension cables can be easily built on site as needed or
purchased in advance from SPARQ or our authorized distributors. 0.3 meter length is typical, with the
landscape 4 in a row potentially using a 1.3 meter solution. For the installation, there are some basic
tools and components that will be required. SPARQ recommends having an AC and DC Disconnect tool
and a Junction box or splice to join the AC cable to the home run cable.
Other options:
• AC Cable splice –to connect and/or extend two sections of cable.
• AC Cable connector waterproof cap –to cover and seal unused AC plugs.
3. INSTALLATION PROCEDURE OVERVIEW
The system must be installed by Rooftop Solar specialists. It is critical that the system is designed and
approved by a certified electrical authority in your jurisdiction. After the racking system is installed, it is
relatively easy to install the Q2000 and the PV modules on the racking. To do so, the following steps are
required:
• Set up AC Trunk cabling and tie downs to match planned microinverter placements.
• Mount the SPARQ microinverter to the racking using two fasteners tightened to 10 ft-lbs / 13.5 N-m.
• Connect the AC Branch Cable to the microinverter and WEEB or ground wire to grounding terminal.
• Install AC junction box to facilitate connecting the AC Branch cable to the home run cable that goes
back to the breaker in main service.
• Connect each of the PV modules leads to the microinverter DC inputs as they are being installed.

• Note: This can be an electric shock hazard. The DC conductors of this photovoltaic system may
be energized.
• Run the SparqLinq Setup Wizard. This can be done during or after the modules are installed; see
next section.
• Test system by turning on main breaker or AC disconnect and monitor the system through the
SparqLinq webpage.
WARNING:Before installation, ensure that the system is disconnected from the utility and
that the AC junction box is not energized! Thereisariskofshockandinjuryifthisisnot
followed.
IMPORTANT: For American split-phase power system, the AC cable has 3 wires. They are
Black (Line1), Red (Line2), White (Neutral). For European and Indian single-phase power
system, the AC cable has 2 wires - Blue (Neutral), Brown (Line). It is important that the Q2000
microinverter is grounded either through the built-in grounding lug using a separate 6 AWG
(16mm²) or 8 AWG (10mm²) solid copper grounding conductor or using an electrical
equipment grounding washer or WEEB (Washer Electrical Equipment Ground).
3.1. SparqLinq Configuration
The SparqLinq is the SPARQ gateway used to provision, monitor and maintain the SPARQ system. Setting
it up is fast and easy and consists of connecting it to the network and following the installation wizard.
3.1.1. SparqLinq Setup
A technician can start setting up the SparqLinq gateway for the site at any time but Q2000
microinverters can only be scanned once the Q2000 is connected to a PV Panel and in the daytime when
there is enough sun to power the Q2000.
NOTE: DHCP IS REQUIRED on the cable modem/DSL router/Fiber connect Internet access device and it is
required to connect the SparqLinq to the internet before or after installation so it can set the internal clock
and perform any software updates before completing the installation.
Warning: The Q2000 warranty is void if they are not connected to the internet through a
SparqLinq.

Figure 10: Inverter detection.
Select “Next Step: Inverter Configuration” to identify and configure the Q2000 microinverters that have
been installed.
3.1.4. Inverter Configuration
Inverter configuration begins with the “scanning” activity, wherein, the SparqLinq surveys the nearby
radio environment listening for any Q2000 microinverters who are generating power as shown in
Figure 11. This can only be done when the microinverters and the PV modules are installed and there is
enough light on the PV modules to power the microinverters. Therefore, this activity cannot be
performed at night.

SPARQ Q2000 Microinverter Installation Manual –Version 1.1, March 2023
Page 19
Figure 11: Inverter detection.
Once the scan is complete (1 minute) the Scan button becomes inactive and the microinverters start
appearing in a list as they are discovered. This is shown in Figure 12.
Figure 12: Scanned inverters.
Note the Serial Number values at your site will not match those depicted above. Instead, they will be the
factory assigned serial numbers for the microinverters installed at your site.
After the scan is complete, all the microinverters discovered are listed and the Re-scan button is displayed.
Carefully inspect the information and ensure that all the installed microinverters are in the list, perform a
Re-scan to direct the SparqLinq gateway to start another scanning activity if some microinverters are not
in the list.
If, after successive scans, the number of microinverters still does not equal the expected total, relocate
the SparqLinq. Try moving the SparqLinq to a different position by first pointing the SparqLinq antenna in
the direction of the installed microinverters. If this is not successful, the next step is to move the SparqLinq
closer to the microinverters. Once an Inverter has been found, it will stay connected to the SparqLinq even
after the SparqLinq is moved back to the starting position.
