Full title and description

STB DIN IEC 62124 E 2001-09 — Photovoltaic (PV) stand‑alone systems — Design qualification and type approval. This document is the English-language national adoption (E DIN) of the IEC draft (IEC 82/259/CD:2001) addressing procedures for qualification and type testing of complete stand‑alone PV systems.

Abstract

This standard specifies qualification and type‑approval tests and evaluation criteria for stand‑alone photovoltaic systems to verify system design, functionality and performance under representative climatic and load conditions. It focuses on system‑level tests (including battery autonomy and recovery after low state‑of‑charge) to provide assurance that a PV stand‑alone system will perform as intended in typical deployment scenarios. The DIN 2001 national adoption was published in 2001 and has since been superseded by the consolidated IEC publication IEC 62124 (2004), which formalised the design verification approach at the international level.

Scope

The standard covers system‑level qualification and type approval of stand‑alone photovoltaic (PV) systems. It defines test sequences and criteria to verify functionality, autonomy (battery supported operation), the system’s ability to recover after prolonged low state‑of‑charge conditions, and performance across representative climatic conditions. The procedures are intended to evaluate the complete PV system (PV modules, mounting, battery/batteries, charge regulator, and typical DC loads; AC loads supplied via inverters are treated as equivalent DC loads for performance assessment). The intent is to produce repeatable, comparable evidence that a given system design meets stated performance and reliability expectations.

Key topics and requirements

• System‑level design qualification and type‑approval tests for stand‑alone PV systems.
• Performance testing including functionality checks, autonomy verification and recovery after low battery state‑of‑charge.
• Test conditions representing a range of climatic zones and typical load profiles to ensure broad applicability.
• Requirements for documenting test set‑up, component configuration and measured results for repeatability and traceability.
• Rule that changes to components or component specifications may require re‑qualification or a new type test to preserve the validity of the original type‑approval.
• Acceptance criteria and reporting formats for certifying bodies, manufacturers and test laboratories.

Typical use and users

Primary users include PV system manufacturers and integrators seeking type approval for stand‑alone designs, independent test and certification laboratories, national standards bodies, rural electrification program managers, procurement agencies specifying verified PV systems, and installers who require evidence of system qualification. The standard is used when a purchaser or regulator requires system‑level proof of performance and robustness rather than component‑only testing.

Related standards

Relevant companion and related standards include IEC/EN series addressing photovoltaic modules, inverters and system safety and testing (for example IEC 61215, IEC 61730 for PV module qualification and safety, IEC 62109 for power converters, and national adoptions/EN versions of IEC 62124). National adoptions and regionally harmonised EN versions (e.g., EN/UNE/ÖVE adoptions) reflect the international IEC work on system verification.

FAQ

Q: What is this standard?

A: It is the DIN national adoption (E DIN IEC 62124:2001-09) of an IEC committee draft covering design qualification and type‑approval testing for stand‑alone photovoltaic systems — a system‑level standard for verifying performance and robustness.

Q: What does it cover?

A: It covers test sequences, performance checks and acceptance criteria to verify system functionality, battery autonomy and recovery, and overall performance under representative climatic and load conditions; testing is focused on the complete PV system rather than isolated components.

Q: Who typically uses it?

A: Manufacturers, system integrators, test and certification laboratories, procurement and electrification program managers, and standards bodies use it to demonstrate or require verified system performance for stand‑alone PV installations.

Q: Is it current or superseded?

A: The E DIN 62124:2001 national adoption is recorded as withdrawn. The international work was formalised in IEC 62124 (published 2004) as the consolidated international publication for design verification; users should reference IEC 62124:2004 (or its current national/EN adoptions) for the up‑to‑date international requirements.

Q: Is it part of a series?

A: Yes — it is part of the IEC TC 82 (Solar photovoltaic energy systems) suite of standards that cover PV module qualification, safety and system testing; IEC 62124 complements module‑level and inverter standards by addressing whole system design verification.

Q: What are the key keywords?

A: Photovoltaic, stand‑alone, island system, design verification, type approval, battery autonomy, LVDC, system performance.
