. EXPEDITED I'ERMIT PROCESS FOR SMALL.SCALE PV SYSTEMS MICRO INVIt{TER The informarion in rhis guideline is inrended ro help Iocal jurisdictions and contractors identify when PV system installaions are simple. needing only a basic review and when an installation is more complex. lt is Iikely that 50%-75% of all residential sysrems will comply wirh rhese simple crireria. For projecs that fail to meet the simple criteria. resolution steps have been suggested to provide as a parh to permit approval. Required InJoflnation Jor Permit: l. Sire plan showing locarion of major components on rhe property. This drawing need not be exactly to scale. but it should represenr relarive locarion o[ componenrs ar sire (see supplied example sire plan). PV arrays on dwellings with a J perimeter space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array conliguration, wiring sysrem. overcurrent protecnon. rnverter, disconnects, required signs, and ac connection ro building (see supplied standard elecrrical diagram). 3. Specihcarion sheets and installation manuals (if available) for all manufactured components including, bur not Iimited to, PV modules, inverter(s), combiner box. disconnecrs, and mounting sysrem.

Step 2; Electrical Revie* o[ PV System (Calculations for Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the following must apply: l. PV modules, utility-interacrive inver(ers, and combiner boxes are identifred for use rn PV systems. 2. The PV array is composed of 4 series strings or less per invertet 3. The total inverrer capaciry has a conlinuous ac power output 1f,440 Warts or less 4. The ac inrerconnecrion point is on the load side o[ service disconnecting means (690.64(B)). 5. One of rhe sEndard electrical diaqrams (El.l, El.la. El.lb. or El.lc) can be used to accurately represent the PV system.
