Island mode details

Three ways to secure power when the grid is gone

From compact single-unit hybrids to scalable multi-unit systems, EnBrilion delivers TÜV-certified battery storage designed for Nordic conditions, integrating seamlessly with existing or new PV and diesel generators.

Why Island Mode Matters

When the grid goes down, your site needs to keep running — without interruption. EnBrilion’s island mode solutions turn outages into manageable events. With solar integration, diesel backup options, and advanced cooling technologies, you stay powered safely and cost-effectively.

Choose the setup that fits your needs

Single-Unit Hybrid ESS

Best for: Small to medium-sized sites needing compact, all-in-one resilience.

Power/Capacity: 60 kW / 208 kWh (optional 60/184)
Cooling: Liquid cooling
Inputs: Grid, direct PV (up to 90 kWp), direct diesel connection
Logic: PV priority, diesel as backup, grid charging at low prices
Applications: Municipal facilities, telecom stations, commercial sites

Applications:

Small municipal facilities (e.g. water pumps, schools, local offices)
Telecom base stations and tower backup
Small-to-mid size commercial buildings
Remote/off-grid sites needing diesel + PV integration

EnBrilion supplies the ESS backbone. PV and diesel can be integrated if already on site, or supplied by us as part of a turnkey solution.

Multi-Unit Parallel ESS Systems

Best for: Large facilities requiring MW-scale backup and Medium Voltage (MV) island mode.

Power/Capacity: Scalable — up to 6 units in parallel (MW-level)

Cooling: Immersion cooling for maximum safety and uptime

Inputs: Direct PV per unit, optional diesel integration via site setup

Switching: <10 ms seamless transition

Logic: Parallel ESS units supply critical loads, ensuring uninterrupted operation of entire facilities

Applications:

Hospitals and healthcare campuses
Data centers with critical uptime requirements
Large industrial plants (plastics, manufacturing, metal)
Municipalities securing multiple services (e.g. water + transport hubs)

Our multi-unit ESS solutions scale to megawatt-level, Medium Voltage (MV) island mode, securing power for critical infrastructure.

Standard C&I ESS

Best for: Municipal and industrial sites that don’t require direct PV input.

Power/Capacity: 130 kW / 261 kWh (immersion or liquid cooling)
Inputs: Grid; diesel integration via site setup
Flexibility: Backup, peak shaving, load shifting
Applications: Water/sewage infrastructure, logistics depots, mid-scale industry

Applications:

Mid-scale industry (logistics depots, food processing)
Municipal water and sewage infrastructure
Local utilities needing reliable peak shaving
Industrial parks or community infrastructure with diesel backup

EnBrilion delivers the ESS as core. PV and diesel can be connected from your site or supplied by us.

Operation Logic Explained

PV priority → maximise renewable input.
Diesel as backup → engage only when required.
Grid optimisation → charge during off-peak hours.
Seamless switching → <10 ms transition keeps critical loads safe.
