EPC and BESS commissioning for industrial projects

A confident execution partner for industrial energy storage projects

Solid Battery Kft. supports modern energy investments from planning to handover with EPC support, on-site commissioning experience, and a practical BESS system integration mindset.

Services

EPC-minded technical support for industrial energy projects

Energy project execution

We provide EPC-minded technical support for corporate and industrial energy investments. The objective is not only to complete the build, but to deliver a system that is reliable, transparent, and ready for handover.

BESS and energy storage infrastructure

For battery energy storage projects, we support commissioning and execution from site checks through safe energization support. Our experience includes CATL, Welion, and Synexel environments.

Electrical system integration

The alignment of BESS, PCS, EMS, and related electrical infrastructure is a critical point in industrial projects. We focus on control, communication, and functional testing to support a stable system start-up.

Technical delivery for solar projects

In solar projects combined with storage, generation, storage, and grid connection define the result together. Our references include a flagship 5 MWp solar and 9.75 MWh storage project.

Project coordination and commissioning support

Pre-commissioning checks, wiring verification, control and communication checks, functional testing, and troubleshooting handover. Structured site work helps bring projects to handover-ready condition.

Mobile BESS rental and R&D validation

Mobile BESS solutions support fast-deployment temporary power and mobile EV charging use cases. R&D and BMS testing experience strengthens OEM, PCS, and control-system alignment during commissioning.

EMS Cloud and remote monitoring

Digital visibility for BESS systems before handover

EMS Cloud and remote monitoring support a project view that is not limited to the site. The goal is O&M readiness: visible energy flow, site-level status, and practical technical signals in one operating picture.

Why us

Handover-focused execution shaped for industrial systems

01

BESS commissioning focus

We sell practical technical work, not generic energy-sector language. Pre-commissioning checks, wiring verification, communication tests, and safe energization support are part of the proven operating scope.

02

Strong partner and technology ecosystem

CATL projects, Welion partnership, Synexel installations, and InPower and Elecode PCS environments connect the technical cooperation to real industrial systems. That supports faster alignment and more targeted problem solving.

03

Verified storage references

References include 5 MWp + 9.75 MWh, 496 kW + 2.15 MWh, plus 1 MW / 2.5 MWh and 1 MW / 3 MWh storage projects. Every communicated figure is based only on verified project data.

04

Coordination on site and in the background

Commissioning is more than a test list: logistics, material staging, spare-part readiness, and partner coordination matter. We carry that work through with technical discipline and a handover-oriented mindset.
