Inspection & Containment
Resident and roving inspection programs at BESS manufacturing facilities. We deploy trained quality teams directly to your production floor to catch defects before they ship.
Vayan's disciplined process playbook covers incoming component QA, in-process checks, and final system verification. Our technology collects inspection data in real time, including:
- Module and rack-level inspection with serial traceability
- Non-conforming part documentation with photos and disposition
- Defect trending and breakpoint management
- Time tracking and workforce performance analytics
Rework & Remediation
System-level defect correction for wiring, thermal management, fire detection and suppression, and enclosure integrity. We fix what's wrong so it doesn't ship wrong.
Our rework capabilities include:
- HV/LV harness inspection, rework, and replacement
- Fire suppression system correction and verification
- Thermal management defect remediation
- Enclosure seal, wiring, and integration rework
- Post-integration system-level QA before commissioning
Battery Module Services
Certified Off-site Inspection & Staging
Regional Technical Centers of Excellence (TCoEs) for complete component-level inspection, containment and rework capacity, inventory management, safe handling protocols, and logistics coordination.
We provide:
- HV-certified teams and climate-controlled storage facilities
- Full inventory management and lot traceability
- Safe handling protocols as needed
- Regional staging to reduce transit risk and lead times
Quality Intelligence & Reporting
Feedback, feed-forward, and real-time reporting are critical priorities for Vayan. Emails or texts with reference information can be immediately sent with non-conforming findings.
Summary reports can be automatically sent (or accessed directly from Vayan's systems) to show all rejects or conformances by day, part numbers, traceability IDs, and more. Root cause analysis, defect trending, and predictive analytics don't just find problems — they prevent them from recurring.
Why Vayan Wins
We Have Expertise
We Know Quality
We Have the Infrastructure
Who We Serve
BESS OEMs & Integrators
"We're ramping production but quality escapes are delaying commissioning and creating warranty exposure."
We've been solving factory-floor quality problems at scale for 46 years. Your BESS ramp doesn't need to reinvent inspection — it needs a partner who already knows how.
Data Center Operators
"We can't afford commissioning delays. We need assurance that BESS units arrive defect-free."
Your data center uptime depends on battery systems that work exactly as intended. Vayan provides independent quality verification that gives you confidence before a single rack goes live.
EPC Firms & Developers
"Post-delivery rework is killing our timelines and margins."
We embed quality at the manufacturing source so problems get caught before they ship — not after they arrive at your site and blow your schedule.
Scaling Fast?
Quality Can't Wait.
Whether you're ramping BESS production, commissioning systems for a data center deployment, or looking to de-risk your supply chain quality — Vayan has the infrastructure, expertise, and workforce to help.
