EXPEDITED PERMIT PI1OCTSS IOR SMALL.SCALI I'\/ SYSTI'II: MICRo_INVERTEF. The information in this guideline is intended to help Iocal jurisdictions and contractors idenrify when PV system lnstallations are simple, needing only a basic review, and when an insallation is more complex. Ir is likely rhar 50 % -75% ot all residenrial sysrems will comply with these simple crireria. For proJecrs rha( fail ro meer rhe simple critena, resolution steps have been suggesred to provide as a path ro permtr approval R equired Infonnation.for Pennit : L Site plan showing location of major components on the property. This drawing need not be exacrly to scale. bur ir should represent relatrve location of components ar site (see supplied example site plan). PV arrays on dwellings with a 3'perimeter space at ridge and sides may not need separare fire service review. 2. Electrical diagram showing PV array confrguration. wiring syslem, overcurrenr protection. invertet disconnects. required signs, and ac connection ro building (see supplied srandard elecrrical diagram). 3. Speci6carion sheets and installation manuals (if available) for all manufactured components rncluding. but not limited to, PV modules, invener(s). combiner box, disconnecrs. and mounting system.

Step 2: Electrical Review of PV System (Calculatrons for Electrical Diagram) In order for a PV sltstem to be considered for an â‚¬xpedited permit ptocess, the following must apply: 1. PV modules, utility-interactive inverters, and combiner boxes are identifred for use in PV systems 2. The PV array is composed of 4 series strings or less per inverter. 1. The total inverter capacity has a conrinuous ac power outpur 13.440 Warts or less 4. The ac interconnection point is on the load side of service disconnecring means (690.64(8)). 5.
