IEC 61727

Abstract

<strong>Scope and object</strong><br>This International Standard applies to utility-interconnected photovoltaic (PV) power systems operating in parallel with the utility and utilizing static (solid-state) non-islanding inverters for the conversion of DC to AC. This document describes specific recommendations for systems rated at 10 kVA or less, such as may be utilized on individual residences single or three phase. This standard applies to interconnection with the low-voltage utility distribution system. <br>The object of this standard is to lay down requirements for interconnection of PV systems to the utility distribution system. <br>NOTE 1&#194;&#160;&#194;&#160;An inverter with type certification meeting the standards as detailed in this standard should be deemed acceptable for installation without any futher testing. <br>This standard does not deal with EMC or protection mechanisms against islanding. <br>NOTE 2 &#194;&#160;Interface requirements may vary when storage systems are incorporated or when control signals for PV system operation are supplied by the utility.
