Full title and description

St IEC 62498-1-2010 cor1-2010 — IEC 62498-1:2010 including Corrigendum 1 (2010). "Photovoltaic (PV)—Requirements for small PV systems — Part 1: Safety and performance" (standard title summarized). This document is the first part of IEC 62498 addressing safety, performance and relevant tests for small photovoltaic systems and their components, and it includes Corrigendum 1 issued in 2010 which corrects editorial and technical errors in the 2010 edition.

Abstract

This standard specifies safety and performance requirements, tests and recommended practices for small photovoltaic (PV) systems intended for residential, commercial and off‑grid applications. Part 1 focuses on system-level aspects including protection, electrical characteristics, installation interfaces and performance verification. The cor1 corrigendum corrects identified errors in the original 2010 text to clarify requirements and improve consistency.

Scope

IEC 62498-1:2010 addresses requirements for the design, operation and testing of small photovoltaic power systems, concentrating on safety, performance and interconnection characteristics. The scope covers system-level considerations for standalone and grid-connected small PV systems, including protection against electric shock, overcurrent protection, isolation, grounding, and interfaces between modules, inverters, batteries and balance-of-system components. The corrigendum corrects technical and editorial inaccuracies in the original edition without changing the intended scope.

Key topics and requirements

• Safety requirements for system components and overall system installation: protection against electric shock and fire hazards.
• Electrical characteristics and limits for interconnection: permissible voltage/current levels, polarity marking and conductor sizing.
• Requirements for protection devices: overcurrent protection, disconnecting means and isolation for maintenance and emergency operations.
• Grounding, equipotential bonding and lightning/ surge protection considerations for small PV systems.
• Performance verification and testing procedures: commissioning checks, functional tests and routine performance measurements.
• Labeling, documentation and user information: required markings, operating instructions and maintenance guidance.
• Corrections and clarifications introduced by Corrigendum 1: editorial fixes and clarification of ambiguous technical clauses to ensure consistent application.

Typical use and users

This standard is used by manufacturers of small PV system components (inverters, charge controllers, combiners), system designers and installers, test laboratories, certification bodies and national standards committees. It guides compliance testing, product development, installation best practices and safety assessments for residential, small commercial and off‑grid PV installations.
