Retrofitting your turbine control system pays off

>> Reduce service costs and increase availability <<

A competitive retrofit wind turbine control system for a variety of turbine types. Replacement of old obsolete turbine control system has been largely ignored, even though retrofitting of ageing Nordex, Micon or Wind World turbine, many of which are surpassing their designed lifetime, has long been an area of interest for service and maintenance companies and the wind turbine owners.

So far, most focus has been put on replacing critical mechanical spare parts in wind turbines - while the obsolete control system has stayed largely untouched. With around 20% of downtime in aging turbines caused by control system errors, a new, modern wind turbine control system makes surprisingly good business sense.

Plug-and-play wind turbine controller for troubleshooting

Spica Technology delivers the only truly competitive alternative to time-consuming control system repairs and price-sensitive second-hand turbine controller purchases on the market today. The Spica SCS Retrofit Turbine Controller, and the easy access to spare parts that follows, allows service providers and owners to move focus from the dwindling second-hand turbine controls pile to that of investment optimisation.

With more than 20 years of experience in the wind power industry, Spica Technology has developed a unique line of retrofit control systems for a variety of wind turbine models currently in operation. Our retrofit wind turbine control system is an affordable, plug-and-play system that allows you to professionally manage your investment and trouble-solve, as you would with a new modern turbine.

Crucial data for a range of turbine types

The Spica SCS Retrofit Wind Turbine Controller is based on advanced technology, comparable to what you find in modern wind turbines. We replace the old wind turbine control system in your Nordex, Micon or Wind World turbine with an up-to-date system that provides you with full, remote access to previously unavailable, valuable data. This extensive data collection makes it possible to monitor the wind turbine closely and carry out predictive maintenance that helps prevent costly breakdowns.

The Spica SCS Retrofit Controller is designed to fit most ageing stall-regulated turbine models, such as Nordex, Wind World, Nordtank, Micon and NEG Micon turbines. The Spica turbine controller is compatible with most monitoring systems and fully compliant with the environment in your turbine. Our retrofit turbines controls are certified by the Danish Authorities for installation and operation in turbines.

Quickly up and running - guaranteed

At Spica Technology, we know and respect the costs connected to downtime. Therefore, we have developed a product aimed at reducing downtime from the moment your order is placed. Besides building a wind turbine control system that physically fits into the turbine controller panel and current wiring - a genuine plug-and-play solution - we provide you with an unprecedented three-year exchange guarantee in case of a controller breakdown or serious malfunction. Also, our controller allows you to add additional sensors, monitoring systems, etc. Once onsite, the Spica SCS Retrofit Controller is installed easily and quickly.

Easy installation – simple to use


Spica Technology is accustomed to handling orders from service providers, professional and individual turbine owners on markets across the world. We deliver the same swift service and close dialogue regardless of company size and number of turbines.


The control system is easily and quickly installed into your wind turbine. We may take on the complete task of installing the retrofit controller or make use of a skilled, local service partner who is familiar with the system.


Help is always nearby, but we doubt that you will need it much. Our Support Hotline is ready to offer qualified guidance and technical support. Remember, we offer a full three-year exchange guarantee.
