Because the DC <br /> circuit is isolated and insulated from ground, these microinverters do not require a Grounding Electrode <br /> Conductor(GEC)connected between each microinverter. This means you don't need to attach a <br /> separate copper grounding conductor to each microinverter or worry about a continuous run to ground. <br /> The result is faster installation with lower materials costs and a safer system. <br /> Int�g�a��� ���ur�c� �nd �ode ���ir�m�n�� <br /> Solar installers must comply with the National Electrical Code (NEC)when installing Enphase <br /> Microinverters. Enphase Microinverters with Integrated Ground meet the requirements specified for <br /> Ungrounded PV Power Systems in sections 690.35 and 690.41 of the 2008, 2011 and 2014 NEC. It also <br /> meets the Underwriters Laboratory(UL) Standard 1741 grounding requirements. <br /> For further information, refer to the whitepaper on Enphase Microinverters and Ungrounded PV Arrays <br /> and other materials at www.enphase.com/Groundinq. <br /> iden�ifyanc� �fii�roina��r��r� .. _ �.._ No9�a��d��9 <br /> 3"" `' terminal <br /> �,�' °��� ' '` , <br /> ��fih Infi��rated �r�u�c� ' '`� <br /> � (. „",✓"' �6 <br /> �" ��.� • <br /> I <br /> Installers and inspectors can easily � � � - ; Flatlid <br /> identify Enphase Microinverters with E --�'°`�W <br /> Integrated Ground. ; ' ''==Po �`�"��°=�`, <br /> o�';��.s;� � <br /> � <br /> A���C�����g �B�i��O�������� � .:•," � Productlabel <br /> �5�6� ������a���� ����� . � ,_, .. . . onbottom <br /> �._.__.. E,...-:.-w-"'"". edge <br /> Enphase Microinverters ship with DC and <br /> AC cables and connectors. The DC connectors attach to the PV module,while the AC connector attaches <br /> directly to the Engage"" Cable. IYs that simple. no additional cabling is needed. <br /> �b��fi ������ �����adi�� , <br /> Electrical code requires two types of.grounding conductors:the Grounding Electrode Conductor(GEC), ' <br /> which is used between the grounding electrode and the point where a normally current carrying conductor <br /> is intentionally bonded to ground and the Equipment Grounding Conductor(EGC),which grounds non- <br /> current carrying metal parts of the system, such as the racking and module frames. <br /> Because Enphase Microinverters with Integrated Ground have DC integrated ground,they do not require '� <br /> a GEC. However electrical code still requires that exposed metal in the array be grounded (NEC 690.43 <br /> and 250.136(A)).This requirement is met for the microinverter because the ground conductor internal to <br /> the Engage Cable acts as the EGC. It may be met for racking and modules with use of an EGC or <br /> WEEBs to provide bonding to this ground system. <br /> .� � --m�:�..,.-�--:.�,��:�::�_-�-:.�:_ ._ -._.. � <br /> O 2014 Enphase Energy Inc.
