If using a roof attachment other than L-feet, refer to that attachment manufacturer's included documentation. 4.0 Grounding Ensure that you fully understand the grounding aspects in this section before proceeding. Important!If installing InvisiMount on a metal roof,you must first ensure that the InvisiMount system is bonded to the roof in compliance with grounding methods as required by the AHJ. This section is intended to provide a well-rounded understanding of all aspects of grounding for SunPower AC Modules when they are installed on the SunPower®InvisiMount" Residential Mounting System; it contains excerpts from the SunPower 96-Cell AC Module Design and Installation Guide(#515791);and the SunPower AC Module Safety and Installation Instructions(#51744);as well as references to the applicable NEC Articles and UL Standards. The InvisiMount system is Listed to UL 2703 for integrated grounding; SunPower AC Modules are a bonding component and are Listed to UL 1741. If you are installing SunPower AC Modules on the InvisiMount system(or any mounting system that is Listed to UL 2703 for bonding—not just for fire classification), no additional grounding hardware, lugs,or copper wire are required on the roof. • The SunPower AC Module is one of the components that bonds all of the metallic non-current carrying components in the system,and is Listed to UL 1741. • As part of UL 2703, only AC equipment grounding requirements apply—no DC system grounding requirements nor DC equipment grounding requirements apply. • The equipment grounding conductor(EGC)that's built into the AC Module cable system is sized appropriately and meets all of the AC equipment grounding requirements for the system. • The AC dedicated branch circuit wiring from the readily accessible disconnect to the array must include an equipment grounding conductor(EGC)in the same raceway or cable as the AC circuit conductors.This EGC must be connected to the green conductor of the transition cable,which is part of the AC module cable system. Document#508988 RevF 13 SunPower Proprietary • The AC Module cable system is"daisy-chained"and therefore if a module is removed from a circuit(for service or replacement,for example),you must first disconnect all power and then install a temporary EGC to bridge the gap by inserting an AC extension cable or other means, in order to maintain effective ground continuity to subsequent modules. Disconnecting a module from the circuit removes voltage and ground from the other downstream modules in the circuit. Extreme care should be taken to ensure that no other energized sources are adjacent to these ungrounded modules. • Because the DC power is internal to the module,a grounding electrode conductor(GEC)for the module or array is not required.The existing AC GEC at the utility service serves as the NEC-required GEC for the structure. • The AC cable grounding path has been tested by an NRTL,and its electrical continuity from the AC cable ground pin to the module frame has been certified. • The AC Module interconnecting cable system provides an internal EGC for grounding the AC Modules. It is the installers responsibility to ground any metallic mounting structure according to local code—recall that if you are installing AC Modules,the system provides grounding of the InvisiMount mounting structure and thus no supplemental grounding is required. • Neither the AC Modules nor the array require a grounding electrode conductor(GEC).The AC Modules must be connected to a dedicated AC branch circuit with an appropriately sized equipment grounding conductor(EGC). The equipment grounding conductor must be connected to a grounding electrode using the existing premises wiring system,typically originating at the building service entrance or service panel. • There is no neutral conductor in the AC Modules. Each AC Module has been designed and is Listed to operate without a neutral conductor.The reference to ground in the AC Modules is through the equipment grounding conductor(EGC). • The AC interconnecting cable system attached to each module's microinverter is fully insulated and includes an internal EGC.The grounding pin is longer than the others in the plug, providing a"first to make, last to break' connection sequence. • The green conductor in the transition cable("trans cable')is connected to the EGC from the utility dedicated branch circuit("house ground"), • The AC ground wire inside the microinverter terminates on the microinverter chassis with a bolted connection, and is environmentally sealed. • The microinverter chassis is bonded to the module frame with stainless steel hardware to provide ground continuity to the module frame. • Each receptacle has a ground pin that is longer than the circuit pins to ensure that the ground is the first to make contact when connecting a given plug-receptacle pair,and the last to break contact when disconnecting the pair. Each SunPower AC Module includes a factory-integrated microinverter(MI)that does not require a neutral wire to be connected to it for operation or for compliance with IEEE 1547. Power produced is conducted on the L1-L2 240 VAC or 208 VAC grid connection. Utility interactive functions in the MI circuitry have been evaluated to IEEE 1547, and use the ground wire instead of the neutral to determine grid values.This functionality is part of its UL Listing. Document#508988 FevP 14 SunPower Proprietary pnry This product must only be connected to a single-phase system(L-L)of a premises with the neutral(N) bonded to ground at the service entrance per code.(The MI does not reference the N to ground internally, therefore this reference must be accomplished only at the service entrance.) Ensure that the installation site has a high-quality N-to-ground reference at the service.The MI determines L-N voltages based on measuring internally from L to the MI chassis, which is connected to the EGC. NI NEC C^. p ar rite and the Ground Path The following are the grounding-related NEC Articles and applicability for SunPower AC Modules on rooftops, and are relevant when SunPower AC Modules are mounted on the InvisiMount system: • 690.41 does not apply to AC modules. • 690.42 does not apply to AC modules. • 690.43 covers equipment grounding,which is the only required type of grounding for an AC module. • 690.45 specifies that the EGC for PV Source and PV Output circuits be sized based on 250.122. Per 690.6, requirements in 690 pertaining to PV Source circuits shall not apply to AC modules because the circuits are internal to the Listed AC module.The AC module output is considered an inverter output. Requirements from 250 for equipment grounding are applied from the service to the junction box.The Listed AC Module interconnecting cable system uses the product safety listing standard which is based on section 250.122 and other sections in 250. • 690.46 modifies 690.45 when the EGC is not protected within a raceway.This is not relevant to the AC Module system because the EGC is within the listed AC Module interconnecting cable system. • 690.47 does not apply to AC modules: • 690.47(A)does not apply when installing an AC system.The AC"system'was already existing on the premises, and hence you are installing AC modules on the AC system. • 690.47(B) applies to DC systems; it does not apply to AC modules. • 690.47O does not apply(see 690.47(B)). • 690.47(D)only provides guidance for a"dc grounding electrode conductor." • 690.48 applies, but isn't relevant. • 690.49 does not apply. • 690.50 applies, but isn't relevant Note as well that Section 4.1 of the SunPower AC Module Safety and Installation Instructions(#51744)explains: As a Listed product,"SunPower AC modules shall be installed and used in accordance with any instructions included in the listing or labeling" (110.3(B)). In addition,SunPower AC Modules"shall be grounded using the integrated equipment grounding conductor...no additional grounding conductor attachment to the AC module is required." System „. round The system features: • Integrated module-to-rail as well as adjacent-module bonding(achieved through the mid clamp and end clamp). • Integrated rail-to-rail bonding(achieved through the self-drilling splice screws and the splice). • System bonding is achieved through the ground lug assembly to the equipment ground conductor(EGC). Note.The ground lug is only required when installing DC modules for arrays that feature AC Modules this system bonding is achieved solely through the system's components. The following two diagrams illustrate the key grounding and bonding aspects of the InvisiMount system—for AC and for DC module scenarios: • the system ground path • each component • each bonding point • the applicable NEC and UL references Document#508988 RevF 16 SunPower Proprietary SunPower lnvisiMount" with AC Modules c {r 5 !MaoInverter l F Ac feblm ...

The AC Module cable system is"daisy-chained"and therefore when a module is removed from a circuit,you must first disconnect all power and then install a temporary EGC to bridge the gap by inserting an AC extension cable (or via other NEC-compliant means), in order to maintain effective ground continuity to subsequent modules. To remove a module from an existing array: 1. Turn off the DC disconnect at the inverter. 2. Using a clamp-on multimeter,verify that current flow has stopped on all DC source circuit conductors. If fuses are installed at the combiner, remove the fuses to isolate the circuit with the target module from parallel-connected sources. 3. Using a clamp-on current meter,test each individual circuit conductor AND each equipment ground conductor on the rooftop before opening any module connectors(before disconnecting any module leads). 4. If the current is zero amps, it is safe to proceed to Step 8. If there is any current present(greater than 0 amps),double-check that the circuit is in fact disconnected from the inverter and proceed to Step 5. 5. If the circuit has been disconnected from the inverter and current is still present, DO NOT INTERRUPT THE CIRCUIT!(Do not unplug any module leads or open any breakers, for example.)It is likely that a short circuit or a ground fault is present—or both. 6. Troubleshoot and correct the short circuit,the ground fault, or both. 7. After verifying that the circuit is disconnected from the inverter and that there are no short circuits or ground faults present, use the clamp-on meter to retest each individual circuit conductor AND each equipment ground conductor.Verify that the current for each is zero before proceeding. 8. Disconnect(unplug)the target module's two electrical leads from the modules that are adjacent to the target module. 9. Remove the adjacent modules and mid clamps, ideally from the side of the row that contains fewer modules between the target module and the end of the row(Fig.Al and Fig.A2). If there is any other grounding or wire management hardware present, remove it as well. 10. Remove the target module. • If the target module will be out of the array solely for the purposes of replacing it with another module immediately, ensure that you remain aware of the adjacent module's temporary partial securement,and execute the swap efficiently, reusing all of the mid clamps and end clamps. • If the target module will be out of the array for an extended period,carefully attach two mid clamps to the now-exposed edge of each adjacent module(Fig.Al, Fig.A2,and Fig.A3)according to Section 1.12.4 of this guide(note that two of the teeth on these mid clamps will instead directly engage the top of the rail— Document#508988 RevF 34 SunPower Proprietary this is acceptable).The mid clamps will keep the modules bonded to the rail,which is bonded to the equipment grounding conductor(EGC)and in turn the grounding electrode conductor(GEC). 11. After replacing or servicing the target module, reassemble the row according to the instructions in this guide. Important!When reinstalling a removed module,shift its original location slightly(min. 1.6 mm [1/16']) relative to its original installed position and in the direction perpendicular to the rail before retightening the mid clamps and end clamps.
