CAUTIONS and WARNINGS
Before installing or using the AC Modules, read all instructions, cautions, and warnings in this
Manual and on the equipment, the PV array, and in this Installation Guide.
WARNING! Hazardous voltages are present inside AC Modules and within
circuits that connect to the AC Modules. Contact with high voltage may cause
death or serious injury. To prevent electrical shock, always disconnect all
power to unit(s) prior to servicing, and NEVER operate this equipment with
the covers removed.
CAUTION! Risk of electrical shock. Do not remove inverter cover. No
installer, user or operator serviceable parts exist inside. Refer all service to a
factory service technician or qualified service personnel.
NOTE! AC Modules are bonded to protective earth (safety ground) through
the utility ground. No other ground connection is needed. The utility ground
connection must be established prior to operating the units. The ground wire
at the service entry should be #14 AWG copper or larger, or sized as
appropriate within your local jurisdiction electrical code. If uncertain, check
with your local code enforcement office for their requirements. Input and
output circuits are isolated from the enclosure, and system grounding, when
required by the National Electric Code Sections 690.41, 690.42, and 690.43,
are the responsibility of the installer. AC output neutral is not bonded to
ground within the AC Module.
NOTE! For domestic US installations, all electrical work must be done in
compliance with local electrical codes and the NFPA 70 National Electrical
Code.
NOTE! Contact your electric utility company before connecting AC Modules
to the commercial electrical grid. Connections to the utility grid must be made
only by qualified personnel.
NOTE! AC Modules are provided with fixed trip limits and shall not be
aggregated above 30 kW on a single Point of Common Connection.
NOTE! Do not connect AC Modules into any AC circuit containing
ground-fault protective devices. Ground-fault protection devices are not
designed for back-fed power and may be damaged.

PRODUCT OVERVIEW
PHONO SOLAR‟s AC Module is a solar panel that produces utility-ready AC power that can
be either consumed on the premise or fed back into the electric utility network. Standard
solar panels produce DC power and require a central inverter to convert DC to AC. When
more power is generated than consumed, you will have what is referred to “net metering”,
where your electric meter will actually spin backwards and you may receive monetary or
other credit for the power fed into the utility grid.
The PHONO SOLAR’s AC Module shall be connected only to a 120VAC, 60Hz dedicated
branch circuit.

DESCRIPTION OF OPERATION
AC Modules are connected internally to the direct current (“DC”) output of a photovoltaic
module (“PV panel”). They convert the DC into utility-ready alternating current (“AC”) suitable
for connection to the commercial power grid. In the event the utility power fails, the AC
Modules will cease producing power as required by the UL 1741 Safety Standard. When
utility power is restored, AC Modules wait slightly more than five minutes as required by UL
1741 before they commence generating power again.
AC Modules operate totally independently of each other. You may start with one AC Module,
then add more to your system as time and budget allow.
AC Modules are designed to connect to a 120V AC, 60 Hz dedicated branch circuit. If 240V
AC operation is desired, two separate “home run” cables and circuits are needed. Connect
equal numbers of AC Modules from Line 1 to Neutral, and from Line 2 to Neutral to maintain
a balanced circuit. You may start with just one AC Module connected L1-N. For optimum
circuit balance, the next AC Module should be connected L2-N.
AC modules are more robust than standard DC solar panels. AC modules eliminate most of
the issues associated with ordinary DC “string” inverter systems:
AC modules are much easier to install.
Lower cost to install.
Far less prone to shading and other problems experienced by string inverter
topologies.
No DC wiring calculations needed.
Eliminate all DC hardware (wiring, central DC to AC inverters, DC disconnects…)

STEP I
INSTALLING THE PV RACKING SYSTEM
NOTE:
REFER TO THE PV RACKING INSTALLATION MANUAL FOR ALL MOUNTING
INSTRUCTIONS AND CALCULATIONS. THE MANUAL IS LOCATED IN THE RACKING
SYSTEM PACKING.
SELECTING A MOUNTING LOCATION
When choosing your PV mounting location:
Choose a location with minimal shading. An ideal solar array location with have little
to no shade from 9:00am to 3:00pm.
The AC module must face south in the northern part of the earth and face north in the
southern part of the earth.
Array tilt. Follow the slope of your roof.
Commercial rack systems are recommended for flat roof tops. Commercial rack
systems are designed with specific tilts for your location.
Choose a location near your utility interface (AC breaker panel). Remember, the
maximum Home Run cable is 100 ft. in length. Ten is the maximum number
of inverters per run of cable no matter what length of cable you are using. This is a
limit imposed by the National Electric Code based on the size of the wires in the
cable and the inverter's maximum output current rating. It relates to the energy loss in
the wire compared to the length of the wire. The installer would need to perform a
calculation to determine the number of inverters versus the total cable length.
The AC Module may be mounted in any orientation. (See Figure 2)
The location selected must comply with the National Electric Code and your local
safety and building codes.
Verify the roof is in good condition before mounting the PV rack system.
NOTE! The installer is solely responsible for:
1) Complying with all applicable local or national building codes, including
any that may supersede this manual;
2) Ensuring that the roof, its rafters, connections, and other structural
support members can support the array under all code-level loading
conditions;
3) Using only those parts supplied with the mounting kits for mounting and
attachment of the AC Modules to the rack frames;
4) Ensuring that lag screws have adequate pull-out strength and shear
capacities as installed (See rack installation manual for details);
5) Maintaining the waterproof integrity of the roof, including selection of
appropriate flashing;
6) Ensuring safe installation of all electrical aspects of the AC Module
array; and
7) Ensuring correct and appropriate design parameters are used in
determining the design loading used for design of the specific
installation. Parameters such as snow loading, wind speed, exposure
and topographic factors should be confirmed with a local building

Copyright © 2011, PHONO SOLAR Page 13 of 29
official or licensed professional engineer (see rack installation manual).
SELECTING THE PROPER MOUNTING STRUCTURE AND HARDWARE
Observe all instructions and safety precautions included with the mounting system
to be used with the module.
Do not drill holes in the glass surface of the module. Doing so will void the warranty.
Do not drill additional mounting holes in the module frame. Doing so will void the
Warranty.
Modules must be securely attached to the mounting structure using four mounting
points for normal installation. If heavy wind or snow loads are anticipated,
Additional mounting points should also be used. Please see the drawing below.
Load calculations are the responsibility of the system designer or installer.
The mounting structure and hardware must be made of durable, corrosion- and
UV-resistant material.
1. Mounting With Bolts
The frame of each module has 8 mounting holes (14mm*9mm) used to secure the
modules to supporting structure. The module must be attached and supported by at
least four ￠8mm bolts through the indicated mounting holes, each connector using
stainless steel. See Figure 2 for each bolt Connection.
Figure 2
Flat washer with diameter of 8.5mm,flexible washer with diameter of 8.2mm.
If module clamps are used to secure the module, the torque on the clamp bolt
should be around 8–10 Nm.
A minimum of four module clamps should be used, two on each long frame side,
in the general clamping areas denoted by the wide arrows on the drawing.
Depending on the local wind and snow loads, additional mounting points may be
required.
2. Other
Other mounting methods are acceptable as long as the minimum requirement
as described under 1.
To ensure that the module and the installation of at least 5cm distance.
Maximum loading capacity of the module for 30lb/ft ^ 2.

Copyright © 2011, PHONO SOLAR Page 14 of 29
STEP II
INSTALLING THE AC MODULES ONTO THE RACKING SYSTEM
When the mounting rack is fully secured to your roof, you are ready to install AC
Modules.
Refer to the rack installation manual for details on mounting the modules to the rack
system.
ORIENTATION AND CLEARANCES
AC Modules must be mounted in a manner that allows airflow under the PV panels.
NOTE! AC Modules are convectively cooled. No fan or other mechanical
means is provided to move the air. Do not block the air flow path.
NOTE! Minimum clearance distances must be observed if your AC Module
inverter system is to operate at maximum rated output in hot weather.
NOTE! Any mounting location that restricts airflow may cause excessive
heating in the AC Module, causing reduced output. Do not mount the PV
panel flush to any surface.
NOTE! Do not remove the leads or cable grips from the AC Module inverter
enclosure. Use only the cables and connectors provided.
When properly installed, AC Modules will resemble the layouts in Figure 5V or 5H. AC
Modules may be mounted either vertically (Figure 3, Illustration „V‟) or horizontally (Figure 3,
Illustration „H‟) with respect to the roof.

STEP III
WIRING YOUR AC MODULES
CAUTION! Utility connection of this unit must be performed by a licensed
electrician or other qualified personnel. Read these instructions completely
before proceeding with installation.
If you do not understand the instructions or steps required herein, seek assistance from
qualified personnel.
Additional information required for installation may be found in the National Fire Protection
Association Publication NFPA70, known as the National Electrical Code., any state building
codes, and any applicable local codes.
The following instructions are intended to be used in conjunction with AC Module Installation
Figures on the following pages. To ensure a safe, reliable installation, please comply with the
instructions as specified, and in the order presented.
CAUTION! Ensure AC conductors have no voltage present. Open all AC
circuit breakers and verify zero volts are present before proceeding!
NOTE! Use only the fasteners provided to mount the AC Modules. Use of
any other hardware is not recommended and may lead to unsafe operation of
your AC Modules.
NOTE! For exterior installations where conduit may be used, weather-tight
conduit fittings complying with requirements in the “Standard for Fittings for
Conduit and Outlet Boxes, UL 514B”, must be used. In such event, install
conduit couplings as required by your local Electrical Code.
WARNING! Before proceeding, ensure the steps below have been performed:
Disconnect AC Power from any point of attachment prior to connecting AC
Modules.
CAUTION! To reduce the risk of fire, connect only to a dedicated circuit
provided with 20 amperes maximum branch-circuit over-current protection in
accordance with the National Electrical Code, ANSI/NFPA 70.

Copyright © 2011, PHONO SOLAR Page 16 of 29
WARNING! To reduce the risk of fire, do not connect to an AC load center
“circuit breaker panel” having multi-wire branch circuits connected.
CAUTION! DO NOT CONNECT MORE THAN 10 AC MODULES TO ONE
CIRCUIT! IF YOU WISH TO INSTALL MORE THAN 10 AC MODULES,
USE SEPARATE HOME RUN CABLES FOR UP TO 10 MORE MODULES
PER CIRCUIT. REFER TO FIGURE 3.
CAUTION! Do not exceed the amperage rating of the circuit box to which
the AC Modules are connected. Consult the National Electric Code or your
local Code Safety Inspector for the applicable rules and regulations in your
area.
Up to 10 AC modules may be connected to a single home run cable. The AC panel should
be connected only to a dedicated branch circuit. Each HelioSentry®is equipped with inputs
for two home run cables (LINE-1 and LINE-2). Up to 20 AC modules may be connected to
one HelioSentry®.
Each LINE must use separate dedicated conductors from each system to the AC disconnect
panel. At that point, each LINE AC output must have its own AC 20 ampere disconnect
breaker.
NOTE! The combined output power of multiple inverters may not exceed the
service rating of the circuits to which the inverters are connected. Consult
ANSI/NFPA 70: The National Electrical Code for guidance.
WARNING! These units are provided with fixed trip limits and shall not be
aggregated above 30 kW on a single Point of Common Connection.
CABLING
AC Module installation kits are provided with UL-approved, sunlight resistant, 3-conductor
cable for connection purposes to utility power. This cable is rated for exterior use without
conduit. Do not substitute Romex®or any other conductor for this cable.
Cable lengths in Table 3 give less than 5% voltage drop for runs of up to 150 feet for various
numbers of AC Modules. If longer distances are involved, increase conductor gauge and/or
decrease in the number of AC Modules per conductor as required. Consult the National
Electric Code or other authoritative sources for appropriate wire size for your installation.
Table 3 –Cable Lengths
Cable Length up to 100‟: Max of 10 AC Modules connected in parallel.
Cable Length 100‟ to 125‟: Max 8 AC Modules connected in parallel.
Cable Length 125‟ to 150‟: Max 6 AC Modules connected in parallel.

Copyright © 2011, PHONO SOLAR Page 17 of 29
Cable lengths exceeding 150’ are not recommended.
To avoid difficulty, keep conductor runs from your AC Modules to the service entry as short
as possible. Long cable runs from the AC Modules may cause AC Modules to “see” higher
voltage than is actually present, leading to occasional shutdown of one or more units in the
circuit due to a perceived (but not real) abnormal utility voltage condition. Cable lengths
longer than 150‟ are not recommended. It‟s advisable to keep your total cable length less
than 100‟ if possible.
Cable should be secured to each AC Module frame with two or more cable clips
The BLACK insulated conductor in the cable is the “LINE” connection. The WHITE insulated
conductor is “Neutral”. The GREEN insulated conductor is protective earth ground. The
neutral conductor must be bonded to earth ground at your service entry. See Figure-4.
Secure the Home Run cable from the last AC Module. Your local building codes may require
that this cable be in conduit. Though the cable supplied is UL-rated for outdoor use without
conduit, your local codes may override any instructions in this Manual.
Penetrating your roof or wall with this cable will likely require a metal conduit to meet your
local electrical codes. It is the installer‟s responsibility to ensure all national and local codes
are observed in the installation of this system.
Do not allow the Home Run cable to rest loosely on the roof. Use cable clips to secure the
cable across the backs of the AC Module frames. Additional hardware (not supplied) may be
necessary for additional cable as required by your local building codes.
