What is BS EN 62109-2:2018?

BS EN 62109-2:2018 is a technical standard that addresses the safety requirements for grid-connected photovoltaic (PV) inverters, which are used in solar power systems. In this article, we will provide a thorough of the standard and its significance in ensuring the safety and reliability of PV inverters.

The Scope of BS EN 62109-2:2018

The standard covers various aspects related to the electrical safety of PV inverters. It outlines specific requirements for the design, testing, and documentation of these devices. The scope of BS EN 62109-2:2018 includes protection against electric shock, fire hazards, mechanical risks, and environmental influences.

Moreover, the standard also encompasses measures to ensure the durability and dependability of PV inverters in a range of conditions, such as high temperatures, humidity, and excessive loads. Compliance with BS EN 62109-2:2018 is crucial to mitigate potential risks associated with grid-connected PV systems.

Key Requirements of BS EN 62109-2:2018

BS EN 62109-2:2018 sets forth several key requirements that PV inverters must meet to ensure safety and reliability. These requirements include:

Isolation and Protection: The standard mandates appropriate isolation techniques to prevent electric shock and reduce the risk of short circuits or other electrical faults.

Clear Markings and Warnings: PV inverters must be clearly labeled with voltage levels, safety instructions, and other important warnings to help users operate them safely.

Temperature Control: The standard establishes temperature limits for different components of PV inverters, ensuring they do not overheat or compromise their performance.

Environmental Compatibility: BS EN 62109-2:2018 requires the evaluation of PV inverters' performance under various environmental conditions, including humidity, extreme temperatures, and mechanical stress.

Benefits of Compliance

Compliance with BS EN 62109-2:2018 provides several benefits to manufacturers, installers, and end-users of PV inverters. Firstly, it ensures a higher level of safety by reducing the risk of electrical accidents and fire hazards associated with these devices.

Secondly, compliance enhances the overall reliability and performance of PV inverters. By meeting the requirements outlined in the standard, manufacturers can develop products that are better equipped to handle different environmental conditions and load demands.
