DMS4 allows EWT customers to monitor the performance of their turbine portfolio with secure user access control. Users can monitor all their wind parks via the HOME section. Selecting a wind park takes the user to the PARK section which shows the operational status, power and wind speed of all turbines in the park, and provides park level reports of daily energy production and availability, downloadable in MS Excel format. Selecting a turbine takes the user to the TURBINE section where live operational data are displayed via a state-of-the-art graphical user interface or dashboard, as well as turbine-level reporting, downloadable in MS Excel format. Turbine alarms and warnings are visible as notifications in all sections. Once the app is installed on a device, the user must be registered on EWT's server before a login is possible. Contact EWT for registration.
