​VINAC Supply Chain Management: 

​Client Background​

A leading Ukrainian electronics retailer with 15 stores across Kyiv and Lviv sought to reduce energy costs and ensure uninterrupted operations amid frequent grid outages. The client aimed to transition 60% of its stores to solar power using pure sine wave inverters, critical for sensitive retail equipment like POS systems and refrigeration units.

​Challenges Identified​

​Grid Instability: Monthly outages averaged 12 hours, risking perishable inventory and sales continuity.

​Equipment Compatibility: Non-sinusoidal inverters caused motor-driven refrigerators to malfunction.

​Regulatory Hurdles: Ukraine’s 2024 energy certification mandates required CE/IEC 62109-3 compliance for imported inverters.

​Logistical Complexity: Cross-border shipping from EU suppliers faced customs delays due to heightened security checks near conflict zones.

​VINAC’s Integrated Solution​

VINAC designed a localized solar-plus-storage system tailored to retail operational needs:

​Inverter Selection: Procured Huawei SUN2000-10KTL-M2 hybrid inverters (10 kW) with pure sine wave output, ensuring compatibility with refrigeration systems and POS terminals .

​Policy Optimization: Leveraged Ukraine’s 2024 Energy Act exemptions to waive VAT for commercial solar installations, reducing upfront costs by 18% .

​Secure Logistics: Routed components through Port of Constanța, Romania to Port of Odessa, Ukraine to reduce total cost.

​Implementation Process​

​Energy Audit: Mapped 24/7 energy consumption patterns to size inverters and batteries for 8-hour backup during peak demand.

​Hybrid System Integration: Installed 144 kWp of LONGi Solar panels paired with SUG inverters and Victron MPPT controllers, achieving 98.5% system efficiency.

​Compliance Assurance: providing CE certificate.

​Client Benefits​

​Operational Resilience: Solar systems eliminated revenue losses during outages, safeguarding €2.1M monthly sales.

​Cost Efficiency: Reduced grid dependency by 55%, cutting annual energy costs from €480,000 to €210,000.

​Regulatory Compliance: CE-certified inverters avoided €50,000 in non-compliance penalties.

​Scalability: Modular design allowed adding 20 kWp per store without downtime.

​Long-Term Partnership​

VINAC established a regional service hub in Kyiv, offering 4-hour emergency repairs and battery swapping. Within 12 months, the retailer expanded solar adoption to 90% of stores, achieving a 4.2-year ROI and earning Green Business Certification from Ukraine’s Ministry of Ecology.

​Conclusion​

By aligning technical specifications with Ukrainian regulations and addressing logistical risks, VINAC enabled the retailer to future-proof its energy infrastructure. This case highlights the critical role of compliant, localized supply chains in driving sustainable transitions in conflict-affected markets.
