SkelGrid supercapacitor energy storage systems

Turn-key energy storage solutions for megawatt-level power needs

SkelGrid is an energy storage system that can be used for short-term backup power or to increase power quality for industrial applications or infrastructure.

As a modular system, SkelGrid components can be customized according to the customers' needs. The system consists of individual SkelMod 102V 88F modules, which come in the industry standard 19" size, and can be installed in 600 mm deep cabinets. The maximum installation size is a standard 40 ft container, which can provide MW level power for short-term needs.

The SkelGrid energy storage system is designed for demanding applications such as voltage and frequency regulation and peak shaving in addition to having the ability to provide reliable backup power for short-term needs.


System examples

  • Max power: 520 kW - 1200 kW
  • Max current: 1400 A - 2500 A
  • Nominal voltage: 612V
  • Capacitance: 14.8 F
  • Nominal power: 75-220 kW
  • Nominal current: 250 A - 750 A

ElevatorKERS - Kinetic Energy Recovery for elevators

Cut elevator energy consumption by up to 70% by capturing and re-using energy

The up and down movement of elevators is in many cases a missed opportunity and a waste of energy. The ElevatorKERS recovers and stores the energy generated by the elevator to return it in the next consumption trip or to support the drive's standby. 

The ElevatorKERS can be installed in new buildings or retrofitted to existing elevators, increasing the energy efficiency of buildings significantly.

Main parameters


  • Optimal power: Up to 15 kW (parallelizable)
  • Stored energy: 60,000 W
  • Nominal power: 6,300 W
  • Efficiency: Up to 98%
  • Standby: <2 W
