All conductors shall be copper. Components are UL listed and CEC certified, where warranted. <br />2. Modules and racking grounding method- All modules will be grounded in accordance with code and the manufacturer’s installation instructions - UL 2703 compliant IronRidge XR Integrated Grounding System using UFO Grounding Mid Clamps and T-Bolt <br />Grounding Lugs - See attached cut sheet. <br />3. If the existing main service panel does not have verifiable grounding electrode, a grounding electrode rod shall be installed, where #8 THWN-2 Ground Serves as both Equipment Ground and Grounding Electrode Conductor. Supplemental grounding electrode <br />required where existing grounding electrode has resistance of more than 25 ohms, or if resistance testing results are not provided (CEC 690.47(A)). If required, multiple grounding electrodes must be at least 6’ apart. (CEC 250.53 (A)(3). <br />4. The GEC / EGC shall be continuous, or when spliced, the splice shall be made by irreversible crimp or exothermic weld. <br />5. Exposed non-current carrying metal parts of module frames, equipment, and conductor enclosures shall be grounded in accordance with 250.13 or 250.136 (a) regardless of voltage. <br />6. Marking will be provided in accordance with Cal-Fire Solar Photovoltaic Installation Guideline <br />7. Utility will be notified prior to use and activation of any solar installation. System will be Commissioned by owner per utility interconnection Agreement. <br />8. AC and DC Conductor sizing and terminations at J-boxes were calculated in accordance with 2019 CEC. All wires to be provided with strain relief at all entry to junction boxes as required by the box listing. <br />9. DC source and output circuits shall be contained in a metal raceway/enclosure within a building - attic/walls and shall be identified every 10’ per NEC 690.31(E). <br />Inverter Ratings: <br /> Enphase IQ8PLUS-72-2-US <br />Max Input Voltage: 60V DC <br />Output: 240 VAC <br />Max Output Current = 1.21A <br />Outdoor NEMA 6 Enclosure <br />UL1741/IEEE 1547 <br />System Configuration: <br />Number of Strings 1 <br />Modules per String 11 <br />Number of Micro-Inverters 11 <br />Module Model Silfab SIL-370 HC <br />Inverter Model Enphase iQ8PLUS-72-2-US Micro Inverters <br />Service Bus Ampere Rating 400A <br />Main Breaker Ampere Rating 200A <br />Max PV AC Output Current 13.3A <br />PV OCPD Size - PV AC Current @125%(1) 30A <br />DC Watts STC 4.07kW <br />Operating AC Voltage 240V <br />Solar Module Ratings: <br />Silfab SIL-370 HC <br /> Pmax - 370W <br /> Vmp - 34.95V <br /> Imp - 10.6A <br /> Voc - 41.75V <br /> Isc - 11.25A <br />SINGLE LINE DIAGRAM: <br />Solar module and rail <br />grounding: UL 2703 <br />compliant IronRidge XR <br />Integrated Grounding System <br />(2) #12 AWG USE-2 <br />Conductors - Enphase Q Cable <br />(2) #12 AWG - Enphase Q Cable <br />(1) #6 AWG Bare Ground <br />Free cable, not in conduit, <br />securely fastened <br />PV SYSTEM EQUIPPED <br />WITH RAPID SHUTDOWN <br />PV Array (P) <br />11 Silfab SIL-370 HC Solar Modules with <br />11 Enphase iQ8PLUS-72-2-US Micro Inverters <br />Integrated DC and AC <br />cables and connectors <br />Enphase Micro-Inverter Solar Module <br />Typical of 11 <br />11 <br />Junction Box (P) <br />UL Listed, NEMA3R <br />Mounted on Rail/Roof <br />(2) #10 AWG THWN-2 <br />(1) #8 AWG THWN-2 Ground <br />In 3/4” E.M.T. or Equivalent <br />EXISTING <br />(3) #3/0 AWG THHN <br />(1) #8 AWG THHN Ground <br />In 1 1/4” EMT or Equivalent <br />(3) #10 AWG THWN-2 <br />(1) #8 AWG THWN-2 Ground <br />In 3/4” E.M.T. or Equivalent <br />200A <br />Main <br />OCPD <br />(1) 20A 2 Pole PV Back-Fed <br />Circuit Breaker - shall be <br />positioned at the opposite <br />end of main breaker <br />Sub Panel (E) <br />225A Bus Rating (E) <br />200A Main OCPD <br />Non-Center Fed (E) <br />(1) 20A PV OCPD (P) <br />Mounted in House <br />(1) 20A <br />PV <br />OCPD(1) 20A <br />PV <br />OCPD <br />Module/Microinverter AC <br />Connectors recognized <br />as disconnect means <br />complying with CEC 690.33 <br />PV Load Center (P) <br />Enphase IQ Combiner 4/4C <br />125A Bus Rating (P) <br />(1) 20A PV OCPD (P) <br />(1) 15A Envoy Monitoring OCPD (P) <br />Mounted on Exterior wall <br />200A <br />Main <br />OCPD <br />200A <br />Main <br />OCPD <br />M <br />M <br />Main Disconnect <br />& Utility Meter (E) <br />1PH 3W 240VAC <br />400A Rated 2 Meter Stack <br />(2) 200A Main OCPD (E) <br />- RAPID SHUTDOWN <br />No Bus Bar <br />Mounted on exterior wall <br />Existing Ground <br />May require new grounding <br />electrodes - see notes below <br />Utility <br />Service <br />(E <br />) <br /> <br />- <br /> <br />E <br />x <br />i <br />s <br />t <br />i <br />n <br />g <br />(P <br />) <br /> <br />- <br /> <br />P <br />r <br />o <br />p <br />o <br />s <br />e <br />d <br />G <br />2333 Evergreen St <br />- 2017743510/04/22
