BESS Battery Storage

Battery storage can be integrated into a photovoltaic system to improve its efficiency and operational flexibility. BESS systems are an essential part of modern energy solutions, helping to optimise consumption, balance peak loads, and enhance the operational reliability and safety of photovoltaic power plants.

Advantages of large-scale battery storage installation

A photovoltaic system can be complemented by large-capacity battery storage (BESS), enabling excess generated energy to be stored and used during periods of peak demand or in the event of a grid outage.

This improves energy self-sufficiency, strengthens supply stability, and increases the overall efficiency of system operation.

Certification

We carry out all our activities in line with internationally recognised standards.

The ISO certifications we hold confirm our expertise, reliability, and responsible approach to environmental protection and occupational health and safety.

Battery storage contributes to the stability and security of the distribution grid.

Logistics and transportation of battery systems

The transport of battery containers is governed by ADR regulations for dangerous goods, including hazard classification and requirements for packaging, labelling, transport, and handling. Battery systems must be properly certified before shipment and must successfully pass integrity and safety testing.

We provide complete logistics in full compliance with these requirements — from collection from the manufacturer to delivery and on-site placement.

Energy storage helps reduce dependence on fossil fuels while increasing the flexibility and reliability of supply, both for businesses and for the wider energy system.

Battery storage systems must comply with the requirements defined by European regulations.

Installation of battery storages

Our expert teams have extensive experience in the delivery of BESS projects across the EU, in full compliance with applicable technical and legislative requirements.

‍

Scope of services provided:

  • Preparation of foundation slab or concrete bases for containers,
  • Placement of containers in accordance with technical drawings and materials,
  • Connection of battery modules, battery management system (BMS),
  • and integration with other electrical system components.
We provide commissioning services, including all required functional and safety tests.

Upon completion of the installation, we carry out full commissioning, testing, and certification.

BESS recovery and testing

After the installation is complete, we will provide:

  • SAT (Site Acceptance Test) — verification of the complete system under real operating conditions
  • Safety compliance testing — in accordance with harmonised European standards, including EN/IEC requirements for stationary batteries and lithium-ion systems
  • Permits and certifications — all documentation required for legal operation
  • Commissioning for commercial operation — including complete documentation and verification of compliance with safety, performance, and reliability requirements
