Our goal
A certificate confirms that we did things correctly on the day of the audit. However, the storage system runs for years — in heat and frost, during grid fluctuations, and after staff changes on the operator's side. Our goal is for it to remain just as safe throughout that entire time, not just on the day of handover.
Safe equipment
Cell selection, fire protection, ventilation, and the mechanical durability of cabinets — layers that must hold up even when no one is watching.
Secure control
Proprietary PLC and EMS developed in-house, segmented networks, and controlled access. We know what is in the control system because we wrote it ourselves.
Safe operation
Supervision, service, and clear procedures for when things don't go according to plan. The operator should know what is happening and what needs to be done.
Accountability
Every intervention, measurement, and shutdown is recorded. When an audit or insurance claim arises, the operator doesn't have to rely on memory, but on records.

Standards we build by
Each standard covers a different layer — production quality, environmental impact, occupational safety, and control system protection.
ISO 9001:2015 — Quality Management System
We manage design, production, and installation according to documented procedures with checkpoints at every stage. Traceable manufacturing and testing documentation exists for every storage unit.
ISO 14001:2015 — Environmental Management
We monitor the environmental impact of both production and operation—from handling chemicals and waste to the recycling plan for battery modules at the end of their service life.
ISO 45001:2018 — Occupational Health and Safety
Working with high voltage and battery modules requires defined procedures, training, and protective equipment. The same rules apply in production and during on-site installation.
IEC 62443 — Security for Industrial Automation and Control Systems
A standard written for OT environments, not office IT. We design the storage control layer with network segmentation, secure communication, and separation of the operational network from the corporate network.
NIS2 — EU Directive on Cybersecurity
The energy sector is a regulated industry. We design our solutions to ensure operators can meet NIS2 requirements for risk management, access logging, and incident reporting.
MFA — Multi-Factor Authentication
Access to the EMS and dispatch interface is protected by multi-factor authentication. Every change to the storage settings is linked to a specific user and logged.
