About
2 out of 3 BESS projects have issues during factory acceptance testing. 🪫That's not a guess — it's what we find, project after project, across Asia, Europe, and the Americas. Voltage deviations between cells that nobody checked. Temperature hotspots hidden inside containers. Performance specs that look great on the datasheet but fall apart when you actually test every rack.I'm Arthur Claire, Director of Technology at Sinovoltaics. I've spent my career on the factory floor inspecting battery energy storage systems — 350+ factories visited, 8GWh+ of projects covered, across 6 continents. My team and I catch the problems that manufacturers don't want you to find.What I focus on:→ BESS factory acceptance testing (FAT) — including our BESSential 100% battery pack diagnostics→ Factory audits and supplier due diligence — China, Vietnam, Thailand, Korea, Europe, US, India→ BESS procurement risk — contract clauses, manufacturer financial rankings, OEM verification→ Quality assurance lifecycle — from specifications to commissioning and monitoringI developed the Sinovoltaics BESS Quality Assurance Plan (QAP) and co-created BESSential, which combines traditional FAT inspection with cell-level diagnostics. It was a finalist at the Energy Storage Awards 2024.I share what I learn here on LinkedIn: real findings from inspections, standards you should know about, contract clauses that save projects, and the occasional Dune reference.If you're developing, financing, or insuring a BESS project and want to reduce your risk: connect with me or book a call.🔋 BESSential white paper: https://sinovoltaics.com/bessential-white-paper/📺 Webinars: https://sinovoltaics.com/sinovoltaics-webinar-series/🏆 Manufacturer Rankings: https://sinovoltaics.com/manufacturer-ranking-reports/🔋 BESS E-Book: https://sinovoltaics.com/sinovoltaics-battery-energy-storage-systems-(bess)-e-book/

Experience

Director of Technology
Lausanne et périphérie
Leading BESS and solar PV quality assurance strategy across 6 continents. Key achievements: → Developed the Sinovoltaics BESS Quality Assurance Plan (QAP), now used as the reference framework for BESS quality inspections covering the full lifecycle from specifications to commissioning → Co-created BESSential with volytica diagnostics — advanced battery diagnostics that go beyond traditional FAT by analyzing 100% of battery packs at the cell level. Finalist at the Energy Storage Awards 2024 → Contributed to the Volta Foundation Battery Report 2025 (773 pages, 120+ experts) → Our findings: 66% of BESS projects miss at least one acceptance criteria during FAT. Safety systems account for 20% of non-conformities → Managing a global team of quality engineers and auditors across China, Vietnam, Thailand, South Korea, Europe, US, and India → Overseeing 8GWh+ BESS inspection across 50+ factories & 19GW+ PV inspection track record across 300+ factories

Head Of Technology
Lausanne et périphérie
Built Sinovoltaics' BESS quality assurance capabilities from the ground up. Designed inspection protocols for battery energy storage systems, established partnerships with battery diagnostics providers, and expanded the quality engineering team to cover BESS projects alongside the existing solar PV inspection business. Drove the company's positioning as a BESS quality specialist — from solar-only to solar + storage.

Contributor
Contributing author to the 2023 & 2025 Battery Reports — a 700+-page annual publication by the Volta Foundation, compiled by 120+ battery professionals from 90+ institutions worldwide. In the 2025 edition, I focused on BESS procurement contract, FAT best practices and inspection findings as well as grid connection bottlenecks. Sinovoltaics data on BESS non-conformities found during FAT was featured in the stationary energy storage chapter (pp. 209-210) - including the finding that 66% of BESS projects miss at least one acceptance criteria when analysed with our BESSential solution In the 2023 edition, I focused on battery cell, battery packs and BESS manufacturing processes, quality assurance and factory acceptance testing

Energy Storage Consultant
Monaco di Baviera
Independent energy storage consultant advising companies across Europe, Asia, and the Middle East on battery strategy, procurement, and product development. → Battery cell and ESS strategic sourcing for multiple clients across 3 continents → Energy storage system product development — from cell selection to EU compliance → Supplier selection, quality control frameworks, and gigafactory audit programs → Technology mapping and market analysis: solid-state batteries, sodium-ion, microgrids → Clients included hardware startups, energy developers, and global consulting firms This period gave me deep, hands-on exposure to every stage of the battery value chain — from cell chemistry to system integration — which directly shaped the quality frameworks I later developed at Sinovoltaics.

Project Manager
RAS Hong Kong
Led the development of a new battery energy storage system at this Hong Kong-based startup electrifying the construction industry. Defined product development processes, aligned cross-functional teams on strategic priorities, and established project and product management frameworks. Short but formative stint that gave me my first hands-on experience developing a battery storage product from concept to prototype — bridging the gap between my previous career in semiconductor imaging and the energy storage industry I work in today.

Solution Creation Manager
RAS Hong Kong
5+ years managing international technology products from development through production at this $3B global leader in imaging and sensing technology. Progressed from project engineer to project manager to marketing manager, overseeing 8 product launches across autonomous driving, drone, industrial, and medical applications. Managed cross-functional teams of 10-15 people across France, Taiwan, the UK, and Asia. Key achievements: recovered a strategic Chinese supplier relationship that was months behind schedule, delivered the product to market (now a major revenue contributor). Increased yield rate by 25% through hands-on supplier quality management. This role built my foundation in international supply chain management, factory-level quality control, and working with Asian manufacturers — skills that directly translate to what I do today in BESS quality assurance.

Research Assistant
Montréal, QC
Master's thesis at CIRANO (Quebec's leading economic policy research institute). Developed econometric models to measure international illegal waste trade flows using Monte Carlo simulations. Not batteries — but this is where I learned to work with large datasets, build quantitative models, and turn complex data into actionable insights. The same analytical approach now drives our manufacturer financial rankings at Sinovoltaics.

Supply Chain Planner
Гренобль
Supply chain planning internship at Schneider Electric (medium voltage equipment). First exposure to industrial production management, SAP ERP systems, and the discipline of on-time delivery in a manufacturing environment. Achieved 100% on-time completion rate during my assignment (vs. 80% average).
