Full title and description

St IEC 62093-2022 — Photovoltaic system power conversion equipment — Design qualification and type approval. This International Standard specifies design‑qualification and type‑approval requirements for power conversion equipment (PCE) intended for long‑term operation in terrestrial photovoltaic (PV) systems, covering grid‑tied and off‑grid DC‑to‑AC inverters, DC‑to‑DC converters, battery charger converters and battery charge controllers for PV arrays up to 1 500 V DC.

Abstract

IEC 62093:2022 (edition 2.0) defines environmental, functional and durability test sequences and acceptance criteria used to demonstrate that photovoltaic power conversion equipment maintains safe and functional performance after exposure to simulated field stresses. The revision narrows the focus to power conversion electronics (PCE) and updates test protocols compared with the 2005 edition.

• Number of pages: 117 pages.

Scope

Applies to electronic power conversion equipment used in terrestrial PV systems (both indoor and outdoor climates per IEC 60721‑3‑3 and IEC 60721‑3‑4). Covers PCE connected to PV arrays with nominal circuit voltages up to 1 500 V DC and AC circuits up to 1 000 V AC; excludes PCE with permanently integrated electrochemical energy storage unless that storage is fully removable for separate assessment. The standard establishes test sequences to assess durability and functional performance after simulated environmental exposure.

Key topics and requirements

• Design qualification and type‑approval procedures for photovoltaic power conversion equipment (PCE).
• Categorization of PCE by size and installation environment with differentiated test sequences and severities.
• Environmental and functional durability tests (thermal cycling, damp heat, vibration, mechanical impact, ingress protection, insulation and functional tests before/after exposures).
• Exclusions and applicability rules (e.g., devices fully integrated into PV modules are not the primary target unless they can be detached and tested separately).
• Updated test protocols and acceptance criteria compared with the 2005 edition; emphasis on power conversion electronics rather than general balance‑of‑system components.

Typical use and users

Used by product designers and manufacturers of PV inverters, converters and charge controllers for type‑approval and design validation; qualification/testing laboratories that perform environmental and functional tests; certification and conformity assessment bodies; procurement and quality teams in utilities, EPC contractors, and system integrators specifying long‑term reliability for PV installations.

Related standards

Replaces and narrows the scope of IEC 62093:2005 (which covered balance‑of‑system components). Relates to IEC 60721 (environmental conditions classification) and other PV/system product standards and certification schemes; it is also adopted as EN IEC 62093:2022 for European national implementation. National and industry-specific variants (e.g., UL national differences) may reference or adapt IEC 62093 test sequences.

FAQ

Q: What is this standard?

A: IEC 62093:2022 is an international standard specifying design‑qualification and type‑approval test sequences and criteria for photovoltaic power conversion equipment intended for long‑term terrestrial PV operation.

Q: What does it cover?

A: It covers electronic power conversion devices (grid‑tied/off‑grid inverters, DC‑DC converters, battery charger converters and charge controllers) used with PV arrays up to 1 500 V DC, and defines environmental and functional durability tests and acceptance criteria; it excludes PCE with built‑in batteries unless removable.

Q: Who typically uses it?

A: Product developers, test houses, certification bodies, system integrators, procurement teams and regulators involved in PV equipment qualification and procurement.

Q: Is it current or superseded?

A: Current — IEC 62093:2022 (Edition 2.0) is the active edition and it cancels and replaces IEC 62093:2005. The IEC record shows the 2022 publication as the valid edition.

Q: Is it part of a series?

A: It is produced by IEC TC 82 (Solar photovoltaic energy systems) and sits alongside related IEC and EN standards for PV components (for example standards addressing PV modules, system testing, electrical safety and environmental classifications such as IEC 60721). It has been adopted regionally as EN IEC 62093:2022 where applicable.
