This manual contains important instructions for the SolarMagic powerstring optimizer SM5400.
4 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.
5www.solarmagic.comconnectors 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.
6All 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-
7www.solarmagic.compacitors 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 Conformance Certications Safety UL 1741 is the recognized standard for Inverters, Converters, Controllers and Interconnect System Equipment for Use with Dis-tributed Energy Resources in the U.S. The SolarMagic powerstring optimizer module complies with the appropriate sections of the

These include shading and module-to-module mismatching which could adversely affect the performance and efciency of the array. Pow-erstring optimizers provide power optimization and monitoring/management for a string level solution.PV arrays are dened 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 signicantly 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 efciency, 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-
14signal 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.Connection Diagrams (EU/EEA)This is for reference only.

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 efcient cable management and run lengths
18between 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 efcient 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 poleFor 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 afxed 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.Figure 1.

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 CommunicationIn order to relay information to the System Manager, each Solar-Magic powerstring optimizer is equipped with a radio transmitterto form ad-hoc and self conguring 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.
23www.solarmagic.comThe topology of the installation drives the placement of the unitsbased on how the modules are strung to each other. The actualinstallation site’s topology will affect the design of the layout andwill determine how many powerstring optimizers and System Manager Devices will need to be deployed.About SolarMagic by National Semiconductor Corporation National Semiconductor leverages a 50-year tradition of power management to deliver solar products for the real world.
