Export Limitation Systems

Main Content

Push Energy has been recently involved in a series of export limitation systems in ground mount and in rooftop commercial sites.

We are seeing that these types of applications are getting more common as the grid constraints have increased.

The technicalities of these schemes are summarised in the ER G100 regulations. Nowadays most of the inverter manufactures provide an export limitation solution that it is G100 certified for LV schemes. However, it is important to note that for HV metered sites there is also the requirement of the installation of a power reverse relay, which makes the scheme a bit more complex.

Another point to bear in mind it is the commissioning process of the export limitation system which is also described in the ER G100 regulations.

As the commissioning could be done in different ways it is important to liaise with the DNO to define a clear procedure.
