Introduction

GB/T 46986, "Requirements for Testing, Documentation and Maintenance of Photovoltaic Systems," aims to provide recommendations applicable to the maintenance needs of grid-connected photovoltaic systems.

The requirements are proposed to consist of the following two parts.

---Part 1: Documentation, Commissioning Testing, and Inspection of Grid-Connected Photovoltaic Systems. The purpose is to specify the documentation, commissioning tests, and inspections required after the installation of a grid-connected photovoltaic system.

Information and documentation provided to the client. This outlines the expected trial operation tests, verification standards, and documentation to validate the system installation.

Safety and correct operation.

---Part 2: Maintenance of Grid-Connected Photovoltaic Systems. The purpose is to specify the system documentation and verification procedures required for the maintenance of grid-connected photovoltaic systems.

Certificates, test and verification reports. Describes the basic requirements and recommendations for prevention, troubleshooting, and performance maintenance of grid-connected photovoltaic systems.

Note. The correspondence between each part and the IEC 62446 series of international standards is as follows.

---Part 1 corresponds to IEC 62446-1;

---Part 2 corresponds to IEC 62446-2.

This document provides necessary information and documentation for grid-connected photovoltaic (PV) systems, including design requirements and procedures for regular inspections and tests.

The law specifies corresponding test procedures for grid-connected photovoltaic systems of different scales, types, locations, and complexities.

1 Scope

This document specifies the information and documentation requirements that need to be provided to users when installing grid-connected photovoltaic systems, and describes commissioning testing, inspection standards, and...

This file is used to verify whether the system installation is secure and whether it is running correctly. This file can also be used for periodic retesting.

This document applies to grid-connected photovoltaic systems, but does not include photovoltaic systems or hybrid systems that use energy storage (such as batteries).

This document does not apply to concentrated photovoltaic (CPV) systems.
