Battery Energy Storage Systems, Verified at Every Stage of deployment.
Celdrix is a European BESS technical partner providing factory testing, pre-commissioning, commissioning, troubleshooting, system integration, and long-term servicing for battery energy storage systems.
We support manufacturers, EPCs, and asset owners throughout the technical lifecycle of energy storage deployment — from factory acceptance testing to site commissioning and ongoing service.
Commission. Integrate. Maintain perform.
Seven stages, one accountable partner
Most providers cover one stage. Celdrix follows the system from the factory floor to the years of operation after — so nothing gets lost in a handover between vendors.
Factory acceptance testing
Independent witnessing of factory tests before the system ships, confirming it meets specification while it's still cheap to fix.
DeploymentPre-commissioning
Verification that the site and installed equipment are actually ready for testing and energization — before the schedule says they are.
DeploymentSite acceptance testing
On-site testing against agreed criteria, with real verification of BMS, PCS, EMS, and SCADA communication — not a checklist exercise.
DeploymentCommissioning
Energization, start-up, and full system integration, bringing the asset into operational service with the documentation to prove it.
DeploymentPost-commissioning support
Performance verification in the critical weeks after go-live, closing out punch lists before they become disputes.
OperationServicing & inspections
Scheduled visits over the asset's lifetime, confirming continued safe and reliable operation under warranty and insurance terms.
OperationTroubleshooting & diagnostics
On-call root-cause diagnosis when something goes wrong, with direct coordination back to OEM and EPC technical teams.
ResponseThree roles, three different problems
The same lifecycle, but the reason someone needs it changes depending on where they sit in the project.
Manufacturers entering Europe
Local technical execution for OEMs without an EU bench yet — FAT witnessing, commissioning, and warranty-period support without standing up a full subsidiary first.
EPCs & integrators
Specialist commissioning capacity for projects that need it without a full-time hire — brought in for the stages that need deep system-level expertise.
Asset owners & operators
Independent verification that a system performs as promised, plus a direct line to someone when it doesn't — not a call centre.
Engineering depth, not a checklist
System-level integration expertise across BMS, PCS, EMS, and SCADA — verifying the system actually works together, not just that each box is present.
EU-based and mobile, able to reach a factory for FAT or a site for an urgent fault without a multi-week lead time.
Field background, not a desk job — commissioning experience earned on live, grid-connected systems, not produced as a paper exercise.
One accountable contact across the full lifecycle, instead of a different vendor for every stage and a gap between each handover.

Built on hands-on commissioning, not advisory paperwork
Celdrix is led by Carl Julius Lukhoba, a BESS commissioning engineer with direct, on-site experience across grid-connected storage systems in Europe.
The approach is system-level: understanding how a battery, its controls, and the grid connection behave together — not just whether each component passes its own isolated test. That's the difference between a system that's signed off and a system that actually performs.
