To avoid risk of electrical shock or re, do not attempt to
disassemble or repair the SolarMagic powerstring optimizer. It
contains no user-serviceable parts and requires no maintenance.
Tampering with or opening the module will void the factory war-
ranty. See warranty for instructions on obtaining service.
To reduce risk of re and shock hazard, install this device
with strict adherence to the National Electrical Code (NEC) ANSI/
NFPA 70, Canadian Electrical Code (CEC) C22.1-09, EU/EEA
Electrical Codes and applicable local electrical codes.
Wear appropriate and suitably rated Personal Protective
Equipment (PPE).
Remove all metallic jewelry prior to installing or servicing solar
arrays equipped with the SolarMagic powerstring optimizer to re-
duce the risk of contacting live circuitry.
Do not attempt to install or service during inclement weather such
as rain and snow, under windy conditions, or in extreme humidity.
Use only accessories recommended or sold by SolarMagic dealers
or distributors. Doing otherwise may result in risk of re, electric
shock, or injury.
To avoid risk of re and electric shock, make sure that exist-
ing cables and connectors are in good condition and are not under-
sized. Use only connectors of the same type and rating as present
in the installation and insure that they are properly sized for the
cable cross section and diameter when making cable splices. Do
not operate the SolarMagic powerstring optimizer with damaged
or substandard wiring (e.g. non UV resistant) or connectors (e.g.
5
www.solarmagic.com
connectors from a different manufacturer. Check all cable glands to
make sure that they are tight.
Do not operate the SolarMagic powerstring optimizer if it has been
physically damaged or subjected to forces beyond its design.
Do not disconnect under load. Authorized service personnel
should reduce the risk of electrical shock by disabling and discon-
necting all AC and DC power sources from the PV system prior to
attempting any maintenance or working on any circuits connected
to the SolarMagic powerstring optimizer. Turning off the inverter
alone will not reduce this risk. Internal capacitors within the in-
verter can remain charged for several minutes after disconnecting
all power sources. All strings that feed into a common combiner
box that is a part of the array being serviced must be covered by an
opaque material to disable the DC source. Isolate each string by
removing the fuses for all strings that feed into a combiner box.
To reduce the risk of burns, do not touch the case of the So-
larMagic powerstring optimizer during operation. Case tempera-
tures can be in excess of 122°F (50°C).
The SolarMagic powerstring optimizer is not intended for
use as a battery charge controller. Do not attach directly to a bat-
tery.
No equipment ground or protective earth terminal is pro-
vided.
6
All wiring methods and wire gauges shall follow the requirements
of the National Electrical Code (NEC) ANSI/NFPA 70, Canadian
Electrical Code (CEC) C22.1-09, EU/EEA Electrical Codes and
the applicable local electrical codes.
It is recommended that the proper wire sizes be selected for the
installation based on calculations to limit the resistive losses to
<0.5% within each string.
Care must be taken to keep the wires and wire bundles away from
any sharp edges which may damage wire insulation over time.
For ground installations or areas subject to oods and snowpack,
the SolarMagic powerstring optimizer must be mounted on a ped-
estal or structure in a manner that is consistent to allow the product
to maintain IP65 and NEMA 4X environmental ratings.
The SolarMagic powerstring optimizer can not be submersed in
liquid.
In areas subject to seasonal snow fall and/or freezing conditions,
care must be taken to safeguard the units from being covered by
snowpack and from being subjected to repeated freeze and thaw
cycles.
ELECTRICAL SHOCK HAZARD
Safety requirements mandate that this equipment not be serviced
while energized. Authorized service personnel should reduce the
risk of electrical shock by disconnecting all AC and DC power
sources from the PV system prior to attempting any maintenance
or working on any circuits connected to the SolarMagic power-
string optimizer. The terminals of the SolarMagic powerstring opti-
mizer may still be energized if the strings and array are connected.
Turning off the inverter alone will not reduce this risk. Internal ca-
7
www.solarmagic.com
pacitors within the inverter can retain their charge for several min-
utes after disconnecting all power sources. All strings that feed into
a common combiner box that is a part of the array being serviced
must be covered by an opaque material to disable the DC source.
Isolate each string by removing the fuses for all strings that feed
into a combiner box.
In EU/EEA installations where the PV systems are oating, both
“+” and “-” leads are fused. Remove both fuses to ensure isola-
tion.
WARNING – Risk of electric shock and/or electric ener-
gy-high current levels.
To avoid the possibility of a severe electrical shock when discon-
necting the Array (+ and -) and the String (+ and -) cables on the
Powerstring module, it is advisable to wait 30 seconds before
handling the unit. This allows the capacitors in the unit time to dis-
charge to a safe level.
Mounting bracket edges can be sharp. Use appropriate pro-
tective gear to avoid cuts while handling the brackets during both
installation and while transporting assembled units for installation.
Do not use the SolarMagic powerstring optimizer’s cables to carry
the unit. Excessive force can damage the cable glands.

Product Description
National Semiconductor’s SolarMagic powerstring optimizer is the
perfect solution to the real-world problems facing PV arrays. These
include shading and module-to-module mismatching which could
adversely affect the performance and efciency of the array. Pow-
erstring optimizers provide power optimization and monitoring/
management for a string level solution.
PV arrays are dened as strings of series-connected PV modules,
which are then paralleled together -usually via a combiner box-
and converted to AC power through an inverter. The key chal-
lenge with PV arrays is to prevent a small amount of real-world
mismatch within the system from signicantly reducing the power
output of the entire array. Examples of mismatch causes include
module-to-module mismatch, shading (e.g. trees, chimneys, over-
head power lines, bird droppings, handrails, etc.), differing module
orientation and tilts, and differing string lengths.
To mitigate the effects of mismatch, system integrators are often
forced to compromise their installation by reducing the size of
the array to avoid shade, thus accepting a lower energy output per
square meter, or adding extra modules in a different part of the ar-
ray, all of which cost money, lower efciency, and/or compromise
aesthetics for the system owner.
To maximize the energy output of each string in the array, Na-
tional Semiconductor has developed the SolarMagic powerstring
optimizer. SolarMagic Powerstring enables each string with the
array to produce the maximum available energy regardless of sys-
tem mismatch. The SolarMagic powerstring optimizer monitors
and maximizes the energy harvest of each string within the array
through advanced algorithms combined with leading-edge mixed-
14
signal technology to recoup energy lost to mismatches.
The SolarMagic powerstring optimizer is designed to be installed
quickly and easily within the traditional architecture of a solar ar-
ray. Each powerstring optimizer comes with a mounting bracket
for easy attachment to any permanent structure, pedestal, rack or
pole. The negative and positive output cables of each string are
simply connected to the string input terminals, while the output ter-
minals on the array side of the powerstring optimizer are connected
to the combiner box or array.

WARNING:
Before installing the SolarMagic powerstring optimizer, read all in-
structions and warning markings located in this manual, as well as
on the powerstring optimizer, inverter, combiner box, and PV mod-
ules. There are lethal levels of voltage and current present within
the SolarMagic powerstring optimizer. Be sure to stringently fol-
low all precautions to avoid injury or death.
Mounting the SolarMagic Powerstring Optimizer
During the site survey, identify best possible locations for the So-
larMagic powerstring optimizer to minimize exposure to UV by
installing the powerstring optimizer in the shade. Insure that the
chosen location is also well protected from rain and snow. Take
into account the most efcient cable management and run lengths
18
between the strings and the homeruns to the combiner box or array.
In some cases, co-locating the SolarMagic powerstring optimizer
next to the combiner box or inverter is the most efcient installa-
tion solution.
The SolarMagic powerstring optimizer’s mounting bracket has
been designed for easy and convenient attachment to any perma-
nent structure, pedestal, rack or pole
For ground or rooftop installations, the SolarMagic powerstring
optimizer must be raised off the surface on a pedestal to prevent
submersion in liquid or repeated snowpack conditions.
If wall mounting, two screws must be used to securely fasten the
bracket to the permanent structure. For systems where wall mount-
ing is not available, the bracket can be afxed to a pole using two
U-bolts. For installations where the mounting structure’s materials
are known to be dissimilar or unknown, insert installer provided
isolation material to prevent galvanic corrosion between the Solar-
Magic powerstring optimizer mounting hardware and the structure
or pole.

Connecting the SolarMagic Powerstring Optimizer to
the PV array
ARRAY STRING
Disable all potential DC sources by covering all PV module strings
that feed into the common combiner box with an opaque material.
Verify that no DC voltages are present on the strings.
As a best practice safety precaution, it is recommended to discon-
nect the cables between the rst and second modules of the PV
string as well as the n and n-1 modules ensuring that at most a
single module’s worth of energy is attached to the PV string being
serviced.
Disable all potential AC sources by disconnecting the inverter from
the combiner box or array.
Isolate each string within the combiner box by removing the
fuse(s) for each string in the combiner box. It is important to note
that oating systems used in the EU/EEA have fuses in the posi-
Figure 2. Top view of optimizer module
20
tive “+” and negative “-” side of each string, so 2 fuses must be
removed to safely disconnect a string from the inverter.
Attach the SolarMagic powerstring optimizer to the string by con-
necting the negative most terminal of the string to the SolarMagic
powerstring optimizer input cable designated “String -”
Complete the connection of the SolarMagic powerstring optimizer
to the PV string by connecting the positive most terminal of the PV
string to the input cable designated “String +”
Attach the SolarMagic powerstring optimizer to the combiner box
or array by connecting the output cables of the powerstring opti-
mizer designated “Array -” and “Array +” to the combiner box or
array.
When the powerstring optimizer is installed and grounding is to be
close to the string, the ground point shall be at the Array (-) termi-
nal for negative ground systems and at the Array (+) terminal for
positive ground systems.
Do not tamper with, replace or cut the connectors on the Power-
string module.
In some installations the positive “+” and negative “-” homerun
string cables can be cut and 2 male and 2 female connectors for the
corresponding cross section and cable diameter can be crimped to
the 4 resulting open ends.

Disconnecting Optimizer Module from the String and
Array
Disable all potential DC sources by activating the DC disconnect
if one is installed and covering all modules that feed into a com-
mon combiner box with an opaque material. Verify that no DC
voltages are present on the strings.
As a best practice safety precaution, disconnect the cables between
the rst and second modules of the string as well as the n and n-1
modules in the same string. This is highly recommended and adds
an additional level of safety by limiting the energy that can pass
through the string being serviced.
Disable all potential AC sources by disconnecting the inverter from
the combiner box or array.
Isolate each string by removing the fuse(s) for each string in the
combiner box. It is important to note that oating systems used in
the EU/EEA have fuses in the positive “+” and negative “-” side
of each string, so 2 fuses must be removed to safely disconnect a
string from the inverter.
Complete the disconnection of the SolarMagic powerstring opti-
mizer from the string by disconnecting the positive most terminal
of the string from the input cable designated “String +”
Complete the disconnection of the SolarMagic powerstring opti-
22
mizer from the string by disconnecting the negative most terminal
of the string from the input cable designated “String -”.
Complete the disconnection of the SolarMagic powerstring opti-
mizer from the combiner box by disconnecting the output cables
designated “Array +” and “Array –”.
Reconnect the wires of the homerun positive and string positive
as well as homerun negative and string negative to reconnect the
string to the inverter without the powerstring optimizer.
Blocking Diode
The SolarMagic blocking diode is designed to block reverse cur-
rent ow by allowing current to ow in one direction only. Due to
interaction, strings with SolarMagic power optimizers installed,
also referred to as assisted strings, will have varying voltage levels
during energy production hours. A single blocking diode must be
installed in each un-assisted string to prevent reverse current from
owing back into that string.
Clustering Rules for ISM Radio Communication
In order to relay information to the System Manager, each Solar-
Magic powerstring optimizer is equipped with a radio transmitter
to form ad-hoc and self conguring networks capable of monitor-
ing the entire solar array.
For best practices, adjust the placement of the SolarMagic pow-
erstring optimizer to avoid any interference or obstruction. Ideal
placement would be off the ground and out of the way of obstruc-
tions.
23
www.solarmagic.com
The topology of the installation drives the placement of the units
based on how the modules are strung to each other. The actual
installation site’s topology will affect the design of the layout and
will determine how many powerstring optimizers and System
Manager Devices will need to be deployed.
