Our products

Product category: Super Capacitors / Double Layer Capacitors

Ultracapacitor Grid Stabilizer (UGS)

The Ultracapacitor Grid Stabilizer combines the STATCOM capabilities of an IGBT-power converter with active power support based on high-power Maxwell ultracapacitors. The UGS can provide voltage and frequency stabilization in transmission or distribution networks with high renewable penetration.

Respecting all relevant grid code requirements the Ultracapacitor Grid Stabilizer allows the operator to provide a number of grid support services and harvest multiple value streams:

Active power injection within 20ms

Fast Frequency Response (FFR)
Providing FFR to stabilize system frequency

Dynamic Reactive Response (DRR)
Reactive current response to compensate voltage dips

Harmonic filtering
Filtering of harmonics based on ultra-fast IGBT-switching

Ultracapacitor UPS System

The Ultracapacitor UPS System provides short-term back-up power and can mitigate process disruptions from frequency or voltage dips based on ultra-fast detection of grid events and successive injection of active or reactive power. The Ultracapacitor UPS System can provide transition power up to 30 seconds until a longer-term back-up source like diesel generator is up and running, thus replacing lead-acid batteries with their limited life expectancy.

MSC Solar

MSC Solar is a hybrid power converter for solar farms based on the „Multi Source Concept“. An energy storage system can be connected to the DC-link of the power converter, thus reducing installation costs and achieving a higher level of system integration in solar + storage projects.

The MSC Solar power converter can also provide reactive power compensation for dynamic grid voltage control.
