BESS and load banks in Denmark – panels, connection and service

Automation and control of your BESS

A BESS needs a control system that can communicate with the BMS, PCS, SCADA and EMS – in real time, because the electricity market doesn't wait.

We deliver BESS automation with integration of Modbus, CAN bus and IEC 61850, so your system can communicate with aggregators, grid operators and your own energy management system without delays. We program SoC (State of Charge) control so the batteries are not overloaded.

Remote monitoring is standard on all our BESS installations. You can monitor the system from a tablet or PC, and alarms are sent directly to you. Do you need automation for other parts of your production? See our automation solutions.

Turnkey and flexible solutions for BESS

At SystemTeknik, we deliver both complete turnkey solutions and flexible partial deliveries for BESS projects. We can advise on and develop several different concepts, so you can use the solution that best fits your existing or new setup.

The panel is the heart of any BESS. This is where power is distributed, protected and controlled. We manufacture AC panels and distribution panels for BESS installations in our own production and size busbar systems, fuses, protection relays and circuit breakers based on your PCS and your battery cell specifications.

• Distribution panels from 800 A to over 1000 A
• Integrated management module
• Circuit breakers and fuse systems to the highest standards
• ABB VMS plastic enclosures and ABB Kabeldon metal enclosures
• Full documentation and CE marking on every panel
• Panel rebuilds and connection to your existing installation

Fire protection of BESS

Lithium-ion batteries require serious fire protection. We integrate automatic fire suppression systems directly into BESS container systems and battery cabinets.

The system detects temperature deviations and gases before an actual fire breaks out and activates suppression in the affected section. The rest of the system can continue operating.

Fire protection is not an optional add-on with us – it is part of the design from the start. Read more about automatic fire suppression.

Load bank testing for BESS and data centers

Before you put a BESS into operation, you need to know that it can deliver the power it is sized for. Load bank testing verifies this under controlled conditions.

We perform load bank testing with both resistive and inductive load banks – on BESS, UPS systems, emergency generators and data center installations. We can test capacities of up to several MW and document all results, so you have data for your operations team and insurance.

Service and maintenance of BESS

A BESS is an investment that needs to be protected. Regular inspection prevents unplanned downtime and ensures you get the full benefit of your system.

We service BESS throughout Denmark from our base in North Jutland. For critical faults, we typically respond within 24 hours.

• Preventive maintenance of battery cells, PCS and panels
• Troubleshooting and rapid response to alarms
• Annual capacity test with load bank

BESS for data centers and industry

Data centers have a particular need for uninterrupted power supply. A BESS can supplement or replace traditional UPS solutions while also participating in frequency regulation when it is not being used as backup – double the value for the same investment.

For industrial companies, it is often about shaving power peaks and reducing the tariff. And solar panels and wind turbines produce power when the weather allows – a BESS stores the surplus and releases it when consumption is high.

We have experience with BESS installations for industrial plants and wind farms. See also data centers and green energy.
