EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62116 testing. IEC EN 62116 provides a test procedure to evaluate the performance of island containment measures used in grid-connected PV systems. This standard describes a guideline for testing the performance of automatic anti-islanding measures installed in or with grid-connected single- or multi-phase grid-interacted PV inverters.
The test procedure and criteria described are the minimum requirements to allow repeatability. The major changes from the previous edition relate to the DC power supply and test conditions.
This standard is applicable to other grid-connected systems (for example, inverter-based microturbine and fuel cells, induction and synchronous machines). However, technical inspection may be required for systems other than inverter-based PV systems.
This standard provides a consensus test procedure to evaluate the effectiveness of island prevention measures used by the power regulator of grid-connected PV systems. Note that although this document deals specifically with inverters for photovoltaic systems, the setup and procedure can also be used, with some modifications, to evaluate inverters used with other generation sources, or discrete anti-islanding devices intended for use with PV inverters or other generations.
Inverters and other devices that meet the requirements of this standard can be considered non-island; this means that under reasonable conditions the device will detect island conditions and stop energizing the public electric power grid.
If the EUT can operate in grid-tied mode from a storage battery, a DC power supply can be used instead of the battery, unless the DC power supply is the limiting device when it comes to maximum EUT input current.
