EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS <br />MICRo-INVERTER <br />The informalion in this guideline is intended to help localjurisdic ons and conrracbrs identify when pv sysrem insallarions <br />are simPle, needing only a basic re1,iew, and when an installadon is more complex. tt is likely rhar 50 % -75 % of all residenrial <br />systems will comply wirh lhese simple criteria. For projecrs rhat fail o meer rhe simple criteria, resolution sreps have been <br />suggested ro provide as a parh ro permir approval. <br />Required Infonnation for Permit: <br />l. Site plan showing location of major components on the properry. This drawing need not be exacrly ro scale, bur ir <br />should represent rclative location of components ar site (see supplied example si!e plan). Pv arrays on dwellings <br />with a 3' perimeter space ar ridge and sides may nor need separate hre service review. <br />2. Electrical diagram showing PV array conhguration, wiring system. overcurrent protection, inverre( disconnects, <br />required signs, and ac connecrion ro building (see supplied standard elecrrical diagram). <br />3. Specincation sheets and installation manuals (if available) for all manufactured components including, bur nor <br />limited to, PV modules, invener(s), combiner box. disconnec6, and mounting system. <br />Step 1 : Structural Review of PV Array Mounting System <br />Is the aray to be mounted on a defrned, permltted rcof srructurc?

PV modules, urilily-inreractive inverters, and combiner boxes are idenrihed for use in PV systems. <br />2. The PV array is composed of 4 series strings or less per invener <br />5. The roral inverter capacity has a continuous ac power output 13,440 Watts or less <br />4. The ac interconnecrion poinr is on the load side of service disconnecring means (690.64(8)). <br />5. one of the sandard elecrrical diagrams (E I . I . E L I a, E I . I b, or E ].
