Diehl  

Diehl inverters do not use RoCoF or VS and Diehl have confirmed that frequency protection settings are compliant with the requirements for GB. ALoMCP believes there is no adjustment needed to be made on Diehl inverters. It is the owner’s responsibility to confirm their equipment is compliant.

Elpower  

Elpower have confirmed that Elpower inverters do not intrinsically have RoCoF or vector shift protection included in the inverter controlling software etc. However, Elpower have always included an ABB CM.UFD.M33(M) protection relay as part of the installation for G59 compliance. The ABB relay needs to be reset in accordance with the attached application note (excluding menus “Nominal voltage” and “I/O setup”). It is the owner’s responsibility to ensure that this is done by an appropriately competent person

Eltek  

The Programme believes that all Eltek Theia and Plantinum inverters did not use RoCoF or VS techniques and therefore there are no adjustments to be made. It is the owners responsibility to confirm this for their inverters.

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.

Emerson Electric  

Emerson have been taken over by Nidec Industrial. Owners of Emerson equipment will need to contact Nidec Industrial to discuss compliance issues on a case by case basis.

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.

Ingeteam state that their inverters do not use RoCoF or VS loss of mains. ALoMCP therefore believes there is no adjustment to make on Ingeteam inverters. It is the owner’s responsibility to confirm this.

LTI ReEnergy  

Owners of LTI inverters can interrogate their inverters via a web browser to check the settings. If the settings need to be corrected, a password is needed to make the changes and the Programme believes that this can be obtained from LTI ReEnergy at https://www.lti-reenergy.com/

Mastervolt  

The Programme believes that Mastervolt inverters up to 20kVA rating are compliant and need no adjustment. The Programme has no information relating to Mastervolt inverters of sizes greater than 20kVA.

It remains the owner’s responsibility to ensure their equipment is compliant.

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 support@mita-teknik.com for assistance.
