We assume a MPP voltage for each module of VMPP = 40.5V. This means the input voltage to the power optimizer is 40.5V and the input current is 245W/40.5V = 6.05A. The micro -inverter MPPT range is from 25V to 60V. Since there are 1 serial connected modules, each providing 245W, the input current for each panel to the inverter is: 245W/40.5V = 6.05A. Each trunk cable can handle up to 15 Microinverters. The first branch of 13 Mircoinverters will have 10.82 amps flowing through the junction box. The total current flowing into the Main Panel will be 10.82 amps. Sheet 19 for MPPT, sheet 8 for the inverter, and sheet 9 for the PV panel. Maximum ambient tempurature is 42 celcius.

In compliance with these standards, the disconnection mechanism operates as follows:1 Turn the c inverter ON/OFF switch, located at the bottom of the inverter, to OFF, or disconnect the AC by shutting off the AC breaker at the site. The DC voltage displayed on the inverter LCD begins to decrease.lf the AC breaker was shut off, the LCD does not display. In this case, wait five minutes.2 When the DC voltage reaches a safe voltage, the PV connectors at the input to the inverter can be disconnected. A galvanic separation then exists between the PV array and the inverter.The disconnection is safe even under single fault conditions. WARNING! Under single fault conditions, the Safe DC voltage is only guaranteed when using modules of up to: 95Voc when using the single phase inverter70Voc when using the three phase inverter Date: 18 -Jun -14 Version: 1.1 Scale: None Project: ku Drawn: Paul Sherer Warning labels for Placement on System roject Details: Client: Martin Ku Address: 22126 Linda Vista PI City: Cupertino, CA 95014 Page Number: 13 R,` SOLAR IhOUNT BEAM COMP, SH rf' EPN SS FLAT !ea X Y4 • S♦7 *4EX BOL, 0%" E Nn4G ," Our, tm UNWJV 2-?iT=NEHarlow QM COMPOSITE slingsha>t 164 Main St., Los Altos, CA 94022 Ph: 650-308-9055 Fax: 650-887-0345 California State Lic: B984488 EXISTING!,'. -'COX PLYWOOD SHT'G VATH UNDERLAYMENT CYVE R 1 xG SKIP SHEATHING ORDER OF INSTALLATION: 1) Locate Rafter, Mark Hole Location, and Drill Pilot Hole 2) Seal Pilot Hole with Sealant 3) Insert Flashing 4) Place Mount 5) Install Lag Bolt with Sealing Washer or Sealant 6) Install Foot with Bolt and Washers QM CONDUIT Slingshot Power, Contractor Equipment Systemthis PhotovotaicSystem 3.185 kW PV System 1 Story Composite General Notes Roof Mounting Hardware b Date: 18 -Jun -14 Project Details: Page Number: Equipment Type Manufacturers and Model Version: 1.1 13 PV Panels Used Sunpower SPR-245NE-WHT-D Scale: None Client: Martin Ku 0 none - Project: ku Address: 22126 Linda Vista PI 14 13 Microinverters Used Power One MICRO -0.25 -1 -US Drawn: Paul Sherer City: Cupertino, CA 95014 SON ARMOUNT Top Mounting UniRac Grounding Clips and WEEBLugs - 225.6 UGC -1 1114 nu ■i■i/■■/■/ i/a■�■i./■�//�■ ///// I , H w■w11 ■iBill was as UNUM: s#� /�1■■■■ /■ ■s■ss�s■ ■■s means -■■ •■■■/ ----- ■ sss■s■ s■■■■#■■■■/■s #■■■w■ ■ 01085 l� M48sHo%s managas e awo%wA88: ■�� 3L ■�■r.■■s■ ■■■■s■■/ ■ss■n ■■ws■■■�//■■ ■ s ■■ 1:80NO ::::::::: U.M.Uig %■moi//i % Ig#s#■sss ��s■■■� s■■I.ass/ ■■■s■/ss unnampon slin shit 164 Main St., Los Altos, CA 94022 Ph: 650-308-9055 Fax: 650-887-0345 California State Lic: B984488 �= U N I RAC} Pub ne2011 June 2011 : t; 2011 by urs—. 1— .411 riphrs resent -d Equipment in this Photovoltaic System 3.185 kW PV System 1 Story Composite Date: Equipment Type Manufacturers and Model Versior 13 PV Panels Used Sunpower SPR-245NE-WHT-D Scale: 0 none Project 13 Microinverters Used Power One MICRO -0.25 -1 -US Drawn: X Slingshot Power, Contractor Grounding Systems: Integrated Grounding (IG) 18 -Jun -14 Project Details: Page Number: 1.1 None Client: Martin Ku 15 ku Address: 22126 Linda Vista PI Paul Sherer City: Cupertino, CA 95014 Top ACltlll�p5 R1UUtli1'r(t �� MOotle c \ ► us I itgrse 2h Slid,- Bit- I grrarnding UGC I a' '!

The WEEB (Washer, Electrical Equipment Bond) is the first production part specifically intended for use in grounding photovoltaic systems There is a family of WEEB parts, one for each kind of photovoltaic mounting system. The WEEBs are used to bond photovoltaic modules to the mounting structure. Aground is connected to the resulting composite structure so that the photovoltaic modules are also grounded This is more technically described in NEC sections 250.136 and 250.134 and discussed at the company website. http 11www wem Inc comWEEB nec.htm.

Testing was performed by lntertek ETL The WEEB are listed to US and Canadian standards Acopy of the certificate is available online at httD,Hwwwwe-Ilc corn PDFIETLmari( pdf Why UL 467 and not UL 1703, standard for photovoltaic modules? ANSVUL 1703 only covers photovoltaic modules Since the WEEB parts involve both module and mounting system. the more general standard. ANSLIUL 467 is required. Also, since ANSVUL 467 was written with AC systems in mind it is a much more severe specification, All ,NEEBs are tested to carry a current of 1530 Amperes for 6 seconds. This is much more than any photovoltaic module can source and is why the WEEBs offer better lightning protection than previous grounding methods.

Ufer around The Ufer Ground is an electrical earth grounding method developed during World War II.It uses a concrete -encased electrode to improve grounding in dry areas. Thetechnique is used in construction of concrete foundations. Construction: Concrete is naturally basic (has high pH). Ufer observed this means that it had a ready supply of ions and so provides a better electrical ground than almost any type of soil. Ufer also found that the soil around the concrete became "doped", and its subsequent rise in pH caused the overall impedance of the soil itself to be reduced.[3] The concrete enclosure also increases the surface area of the connection between the grounding conductor and the surrounding soil, which also helps to reduce the overall impedance of the connection. Ufer's original grounding scheme used copper encased in concrete. However, the high pH of concrete often causes the copper to chip and flake. For this reason, steel is often used instead of copper. When homes are built on concrete slabs, it is common practice to bring one end of the rebar up out of the concrete at a convenient location to make an easy connection point for the grounding electrode.[4] Ufer grounds, when present, are preferred over the use of grounding rods. In some areas (like Des Moines, Iowa) Ufer grounds are required for all residential and commercial buildings.[5] The conductivity of the soil usually determines if Ufer grounds are required in any particular area. An Ufer ground of specified minimum dimensions is recognized by the U.S. National Electrical Code as a grounding electrode.[6] The grounding conductors must have sufficient cover by the concrete to prevent damage when dissipating high -current lightning strikes.[7] A disadvantage of Ufer grounds is that the moisture in the concrete can flash into steam during a lightning strike or similar high energy fault condition. This can crack the surrounding concrete and damage the building foundation.[8] slingshot 164 Main St., Los Altos, CA 94022 Ph: 650-308-9055 Fax: 650-887-0345 California State Lic: B984488 Equipment in this Photovoltaic System 3.185 kW PV System 1 Story Composite Equipment Type 13 PV Panels Used 0 13 Microinverters Used Two Pole . Ground and Neutral As the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. Under certain conditions, a conductor used to connect to a system neutral is also used for grounding (earthing) of equipment and structures. Current carried on a grounding conductor can result in objectionable or dangerous voltages appearing on equipment enclosures, so the installation of grounding conductors and neutral conductors is carefully defined in electrical regulations. Where a neutral conductor is used also to connect equipment enclosures to earth, care must be taken that the neutral conductor never rises to a high voltage with respect to local ground. Definitions Ground or earth in a mains (AC power) electrical wiring system is a conductor that provides a low impedance path to the earth to prevent hazardous voltages from appearing on equipment (the terms "ground" (North American practice) and "earth" (most other English-speaking countries) are used synonymously here). Under normal conditions, a grounding conductor does not carry current. Neutral is a circuit conductor that carries current in normal operation, which is connected to ground (or earth). In a polyphase or three -wire (single-phase) AC system, the neutral conductor is intended to have similar voltages to each of the other circuit conductors. By this definition, a circuit must have at least three wires for one to serve as a neutral. In the electrical trade, the conductor of a 2 -wire circuit that is connected to the supply neutral point and earth ground is also referred to as the "neutral".[ I ]The NEC and Canadian electrical code only define neutral as the first of these. In North American use, the second definition is used in less formal language but not in official specifications. In the UK the IET definition of a neutral conductor is one connected to the supply system neutral point, which includes both these uses. All neutral wires of the same electrical system should have the same electrical potential, because they are all connected through the system ground. Neutral conductors are usually insulated for the same voltage as the line conductors, with interesting exceptions.[2] Neutral wires are usually connected at a neutral bus within panelboards or switchboards, and are "bonded" to earth ground at either the electrical service entrance, or at transformers within the system. For electrical installations with three -wire single phase service, the neutral point of the system is at the center -tap on the secondary side of the service transformer. For larger electrical installations, such as those with polyphase service, the neutral point is usually at the common connection on the secondary side of delta/wye connected transformers. Other arrangements of polyphase transformers may result in no neutral point, and no neutral conductors. Combining neutral with earth Stray voltages created in grounding (earthing) conductors by currents flowing in the supply utility neutral conductors can be troublesome. For example, special measures may be required in barns usedfor milking dairy cattle. Very small voltages, not usually perceptible to humans, may cause low milk yield, or even mastitis (inflammation of the udder).[31 So-called "tingle voltage filters" may be required in the electrical distribution system for a milking parlour. Connecting the neutral to the equipment case provides some protection against faults, but may produce a dangerous voltage on the case if the neutral connection is broken. Combined neutral and ground conductors are commonly used i n electricity supply companies' wiring and occasionally for fixed wiring in buildings and for some specialist applications where there is 1 ittle alternative, such as railways and trams. Since normal circuit currents in the neutral conductor can lead to objectionable or dangerous diffibmces between local earth potential and the neutral, and to protect against neutral breakages, special precautions such as frequent rodding h (multiple ground rod connections), use of cables where the combined neutral and earth completely surrounds the phase c ct d thicker than normal equipotential bonding must be considered to ensure the system is safe. Shared neutral A shared neutral is a connection in which a plurality of circuits use the same neutral connection. This is also known the circuits and neutral together are sometimes referred to as an Edison circuit. ,and Single phase �e�% qY Main article: Split -phase electric power In split phase wiring, for example, a duplex receptacle in a kitchen, devices may be coif je�d wi Il i- cable that has three conductors, in addition to ground. The three conductors are usually coloured red, black, and white. The white se es as a common neutral, while the red and black each feed, separately, the top and bottom hot sides of the receptacle. Typically such receptacles�sre� supplied from two circuit breakers in which the handles of two poles are tied together for a common trip. If two large appliances are used at once, current passes through both and the neutral only carries the difference in current. The advantage is that only three 'Ai res are required to serve these loads, instead of four. If one kitchen appliance overloads the circuit, the other side of the duplex receptacle w ill be shut off as well. This is called a multiwire circuit. Common trip is always required if there are loads that use more than one phase simultaneously. The common trip prevents overloading of the shared neutral if one device draws more than rated current. —f i Torque Information & Grounding Information UP ,;C; . t'',r Date: 18 -Jun -14 Project Details: Page Number: Manufacturers and Model Version: 1.1 Sunpower SPR-245NE-WHT-D Scale: None Client: Martin Ku none - Project: ku Address: 22126 Linda Vista PI 17 Power One MICRO -0.25 -1 -US Drawn: Paul Sherer City: Cupertino, CA 95014 UP ,;C; . t'',r �pha Jltvo �JTvIF l�itv GENERAL NOTES (Cont UNGROUNDED PANEL POSITIVE GROUNDED PANEL � GENERAL NOTES 1.

The FIRE CLASSIFICATION FOR ROOF MOUNTED SOLAR PHOTOVOLTAIC language of this section states that the fire classification of PV systems must match the minimum required fire classification of the roof assembly over which they are mounted as required in IBC Section PANELS/MODULES [SYSTEMS] AND APPLICATION OF THE 2013 CALIFORNIA 1505. With any rooftop structure. the PV structure should not degrade the fire resistance properties of BUILDING STANDARDS CODE the roof. so as not to place the building and its inhabitants at an unanticipated risk. Ho,.vever. straightforward implementation of this requirement is not possible for the follo�,-ing reason(s). On January 1. 2014 the 2013 California Building Standards Code. California Code of Regulations (CCR1. Title 24. became effective. As part of the 2013 California Building Standards Code, Part 2 and P`/ modules are a component of a rooftop mounted PV system and. although PV modules can receive a Part 2.5 provisions for the fire classification of roof mounted photovoltaic panels modules [systems] :,:ere fire classification rating in accordance .with UL 1703. there are currently no PV systems ••,'ith a fire updated to comply .%ith the most recent edition of Under,rriters Laboratories Inc.

The Office of the State Fire Marshal (OSFM)':vas recently informed by industry that presently there is an In the absence of a PV system fire rating. it may seem appropriate to substitute the PV module fire insufficient supply of UL 1703 compliant Class A.

The issuance of the most recent edition of UL 1703 and its adoption into the 2013 California Building Code (CBC). specifically Section 1505.9 and California Residential Code (CRC i Over the past five years. rigorous testing by UL and Solar ABCs revealed that the performance of a Section R902.4 necessitates the need for guidance from the OSFM on this matter. These sections read system c, hich includes PV modules on standoff mounted racks) exposed to fire or flame is not the same in part: as that of a module alone. Currently, modules receive a fire classification rating based on testing the module alone. not as part of a PV system. The results of these tests sho':r that actual performance of a "Rooftop mounted photovoltaic panels and modules [systems] shall be tested, listed rack -mounted PV system exposed to fire or flame is strongly dependent on the mounting geometry of and identified with a fire classification in accordance with UL 1703...
