EXPEDITED PERIVTIT PROCESS'FOR SMALL_SCALE PV SYSTEMS MICRO- INVERTER The rnformation in this guideline is intended Io help local Jurisdictions and conrracrors identify when PV svsrem rnsrallarions are simPle. needing only a basic review. and when an installalion is more complex lI is Iikely lhar 50%-75% of all residential systems will comply wlth these simple crileria. For projecrs rhar fail ro meer rhe simple crireria. resolurion sreps have been suggested to provide as a parh to permit approval Requircd lnJownation Jor Permit: l. Srle plan showing location of major componenrs on rhe property This drawing need nor be exactly ro scale, bur rr should represent relative location of components at sile (see supplied example sire plan) PV arrays on dwellings with a S perimeter space at ridge and sides may nor need separate hre service review 2. Electrical diagram showing PV array conhguration, wiring system, overcurrenr prorecrion. tnverrer, disconnecls. required signs, and ac connection to building (see supplied srandard electrical diagram). l. Specincation sheets and installation manuals (if available) for all manufactured components including, bur not Iimited to, PV modules, inverter(s), combiner box. disconnects, and mounring system.

Step 9: Electrical Review o[ PV System (Calculations lor Electrical Diag,am) ln order for a PV system to be considered for an expedited permit process, the fotlowing must apply: I PV modules, utilily-interactive inverters. and combiner boxes are identihed for use in PV systems 2. The PV array is composed of 4 series strings or less per inverre. 5. The roral inverter capacity has a conrinuous ac power ourpur I1.440 Watls or less 4.
