SkelGrid is a full 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.

Ultracapacitors are ideal for power quality applications

The SkelGrid product family is based on Skeleton Technologies' industry-leading SkelCap ultracapacitors, which provide higher power and energy than any competing ultracapacitor on the market.

The SkelCap cells are also superior to batteries, currently the number one choice for backup power needs, in many ways: ultracapacitors can provide up to 60 times more power than batteries, can operate near full efficiency even at -40°C/°F, and can charge and discharge almost instantly for more than a million cycles. Ultracapacitors have the ability to react in milliseconds, enabling seamless bridging and backup power.

The SkelGrid product family 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.
