Emergya Wind Technologies (EWT) EWT turbines incorporate a loss of mains relay in the control system of the wind turbines. EWT turbines are not double fed induction generators, nor synchronously connected, and hence where these relays cannot be reset to be compliant with EREC G59, the loss of mains function can be disabled.
Enercon State that inverters do not use VS or RoCoF. However many (but not all) Enercon devices have a separate relay which provides LoM functions and will need to be confirmed compliant and/or reset by a competent person. Enercon can be contacted to advise on what is required at each installation.
Enphase Enphase Energy has confirmed that their M-Series microinverter products can have their Grid Profile settings updated such that RoCoF or vector shift loss of mains techniques are not used. To achieve this an Envoy-S running software version 4.4 or higher must be installed at the site and the UK G59-3-7:2019 M-Series (ver 1.0.14 or higher) Grid Profile must be applied to the microinverters via Enlighten or the Enphase Installer Toolkit App.
It is the system owner's responsibility to organise for these settings to be changed on their installation. In the first instance it is recommended that the original installer is contacted. For further guidance please contact Enphase Customer Support team at the link below.

Mita Teknik Mita Teknik supply controllers/control systems for wind turbines, with frequency settings within the controllers being set by the wind turbine manufacturer or by the installer as part of the commissioning process. Some Mita Teknik controllers include loss of mains protection. Owners of Mita Teknik controllers with loss of mains (eg vector shift) will need to contact Mita Teknik for advice on how these settings can be made compliant with G59. Confirmation of the frequency settings can be undertaken by installers/contractors familiar with Mita Teknik controllers, but the loss of mains or anti-islanding protection needs to be referred to Mita Teknik. Mita Teknik can be contacted at [email protected] for assistance.
