Smart, Safe and
Scalable Energy Storage.

Battery island mode allows your site to disconnect from the public grid and operate as an independent microgrid during power outages. An Automatic Transfer Switch detects the failure, the BESS immediately stabilises voltage and frequency, and your critical loads continue without interruption. When the grid is restored, the Energy Management System synchronises and reconnects automatically. No manual intervention is required at any point.

The transition is automatic and takes place within milliseconds. When the grid fails, the Automatic Transfer Switch isolates the site and the battery takes over with no manual intervention required. In most installations the transition is fast enough that equipment with standard internal power supplies will not detect any interruption. There is no need to manually start equipment, wait for a generator to warm up, or accept any gap in power supply.

Island mode is designed for any organisation where a power interruption causes serious operational, financial or safety consequences. In Sweden the most common applications are hospitals and healthcare facilities, water treatment and municipal infrastructure, industrial production sites, data centres and IT operations, telecom networks and base stations, and public safety facilities. Remote locations with unstable grid connections also benefit significantly.

In many cases, yes. A properly sized BESS island mode system can fully replace a diesel generator for backup purposes, eliminating fuel costs, noise and emissions, and significantly reducing maintenance requirements. For sites with very long outage requirements, EnBrilion systems can also integrate with existing generators, using the battery to absorb peak loads and bridge shorter outages, significantly reducing generator runtime, fuel consumption and maintenance requirements. The two technologies work well together.

Runtime depends on battery capacity and your critical load profile. EnBrilion systems are sized specifically to each site based on your critical loads and backup requirements. For sites with on-site solar or a generator, the system can extend runtime significantly by managing all energy sources through the integrated Energy Management System. Contact us for a sizing assessment based on your specific loads.

Sizing depends on three factors: which loads are critical, how long you need to run during an outage, and whether you want to integrate solar or a generator. EnBrilion offers systems from 60 kW up to multi-megawatt scale. We handle the load analysis and system design as part of the project process, so you receive a system sized precisely to your requirements without over-investing in capacity you do not need.

Yes. EnBrilion island mode systems can integrate with existing PV installations. Without a battery and grid-forming controller, solar panels automatically shut down during a grid outage to comply with anti-islanding regulations. With an EnBrilion BESS configured for grid-forming operation and the EMS, your solar can continue producing during island mode, extending battery runtime and reducing dependency on the grid or a diesel generator throughout the outage.

Yes. All EnBrilion systems are designed and commissioned to Nordic and EU standards, including SS-EN 50549 and applicable DSO connection requirements. Systems are TÜV-certified and rated IP54 to IP55 depending on model. EnBrilion provides technical documentation and supports the grid approval process as part of the delivery scope.

Yes. Between outages, your BESS can participate in energy markets through peak shaving and load shifting, directly reducing your energy costs. Systems meeting prequalification criteria can also participate in ancillary service markets such as FCR-N via Svenska kraftnät, with income subject to market conditions. EnBrilion partners with CheckWatt and Aire for energy management and market participation. The same system that protects your operations during outages works to lower your energy costs during normal grid-connected operation.

The process starts with a no-obligation site assessment where we review your critical loads, existing grid connection and backup requirements. From that we design a system and provide a detailed proposal. Contact us at info@enbrilion.com or through the contact form on this page to schedule an initial consultation.
