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.
EPC and BESS commissioning for industrial 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
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.
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.
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.
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.
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 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
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.
BESS / PCS / EMS
EMS Cloud
Real-time energy flow visibility across generation, storage, and grid connection.
Multi-site status overview for project and operations teams.
BMS cluster monitoring for battery subsystem status checks.
PCS curve tracking for active power, reactive power, and voltage.
Why us
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.
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.
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.
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.

Cooperation
We clarify the project goals, technical environment, and handover expectations quickly.
Based on BESS, PCS, EMS, electrical connections, and site conditions, we define the execution framework.
We provide a transparent, decision-ready proposal with the required technical steps and cooperation points.
With site support, testing, and troubleshooting handover, we bring the system to the threshold of operational use.
