BS IEC 62891:2020

Overview

BS IEC 62891:2020 establishes the requirements for the maximum power point tracking (MPPT) efficiency of grid-connected photovoltaic (PV) inverters. This standard is crucial for ensuring that PV systems operate at optimal efficiency, thereby maximising energy production and enhancing the overall performance of solar energy installations.

Key Requirements

The standard outlines specific criteria for evaluating the MPPT efficiency of PV inverters. Key requirements include:

• Testing Conditions: Inverters must be tested under standardised conditions to ensure consistency in performance evaluation.
• Efficiency Metrics: The standard specifies the calculation methods for determining MPPT efficiency, including the necessary parameters to be measured.
• Reporting Standards: Manufacturers are required to provide detailed reports on MPPT performance, including any deviations from expected efficiency levels.
