Client Challenges
This leading equipment manufacturer faced structural design and integration bottlenecks in high-end project bidding.
As a well-known PV equipment supplier in the industry, this manufacturer encountered challenges that its internal capabilities couldn’t quickly match when expanding into the market for highly customized primary equipment enclosures requiring extreme environmental adaptability (such as the IP54/C5 ratings and adaptation to -40°C to +55°C temperature range and heavy sandstorms required by this Hami project):
High Standard Structural Design Requirements: The end customer demanded enclosure protection levels (IP54), anti-corrosion capabilities (C5), and resistance to sandstorms (requiring verification via wind tunnel tests) and extreme temperature differences (-40°C to +55°C) far exceeding standard requirements, putting immense pressure on their existing structural design and manufacturing capabilities.
Tight Delivery Schedule Pressure: The end project required completion of production, integration, and delivery for the first batch of at least 50 enclosures within 4 months, which the client's internal production and integration processes struggled to support.
Complex System Integration Workload: Efficiently and reliably integrating multiple brands and nearly a hundred models of primary equipment specified by their customer (string inverters, pad-mounted transformers, communication cabinets, etc.) along with complex auxiliary systems (including dual-source precision air conditioning, HFC-227ea fire suppression, smart monitoring units) into the enclosures consumed significant engineering resources, becoming a production bottleneck.
Balancing Cost and Quality: While meeting stringent technical requirements, they also needed to control manufacturing costs to maintain market price competitiveness.
Desire to Focus on Core Business: This manufacturer wished to allocate more resources to its core competencies in electrical equipment R&D, software algorithm optimization, and marketing, rather than asset-heavy structural manufacturing and cumbersome integration processes.

Customized High-Performance Structure Supply
Based on the extreme environmental requirements of the end project, we designed and manufactured reinforced modular structures featuring double-layer insulation, sand-trap labyrinth air inlets, and high-reflectivity white coating meeting IP54 protection and C5 anti-corrosion standards. Utilized 2.5mm thick Zinc-Aluminum-Magnesium coated steel (ZMA310), fully automated robotic welding, and a three-layer coating system (epoxy zinc-rich primer + epoxy mid-coat + polyurethane topcoat) compliant with ISO 12944 C5 standards to ensure structural strength, sealing, and durability. Modular design facilitated transportation and incorporated standardized interfaces, laying the groundwork for rapid subsequent integration.
Professional System Integration Services
We assembled a dedicated project team and, strictly following the client's BOM and technical requirements, efficiently completed the installation, wiring, and connection of all equipment, including the client-supplied string inverters, pad-mounted transformers, and medium/low-voltage switchgear, within our ISO Class 8 certified clean integration workshop. Performed precise integration and commissioning of auxiliary systems like industrial air conditioning and smart ventilation systems, HFC-227ea fire suppression systems, video surveillance, and environmental monitoring systems. Executed rigorous in-process quality control and full system functional joint commissioning, IP54 protection level rain tests (60 minutes duration), and electrical safety (ground continuity 20MΩ) tests prior to shipment to guarantee integration quality.
Collaborative Engineering & Project Management
We held bi-weekly online collaboration meetings with the client's engineering team and utilized a shared PLM platform to optimize structural design and integration plans for a perfect match. Provided a cloud-based project management system for transparent progress tracking, ensuring on-time, high-quality completion of structure manufacturing and system integration for delivery to the client for final factory acceptance.
Technical Advantages
Advanced Structural Design & Simulation Capabilities: Professional structural engineering team with capabilities in thermal simulation and structural strength Finite Element Analysis (FEA) using ANSYS to handle complex environmental requirements.
Precision Sheet Metal Fabrication & Surface Treatment Processes: Possess German YAWEI laser cutting and bending equipment, guaranteeing dimensional accuracy (±1mm), sealing, and superior weather resistance of structures.
Professional Electrical & System Integration Capabilities: Experienced integration teams (average 15+ years industry experience) and MES system-based standardized operating procedures ensure efficiency and quality (First Pass Yield >99.5%).
Flexible Manufacturing & Rapid Response: Adopting a Lean Manufacturing model, capable of quickly adjusting production schedules based on customer orders to meet urgent delivery needs (expedited order response time <48 hours).
Strict Quality Control System: ISO 9001:2015 certified, comprehensive quality control from raw material inspection (providing Material Test Certificates - MTC) to final integration testing.

Impact and Value
Our collaboration not only solved specific project challenges but also fueled this leading manufacturer’s long-term growth.
Won Key Market Orders: Enabled the client to secure a large power station project order worth nearly 100 million RMB with extremely high technical requirements, increasing market share.
Focused on Core Competencies: Allowed the client to reallocate approximately 25% of internal engineering resources to core strengths like electrical equipment R&D, brand building, and market expansion.
Enhanced Product Portfolio Competitiveness: Enabled them to quickly launch high-end enclosure products meeting stricter environmental standards like IP54/C5, about 6 months ahead of competitors.
Optimized Supply Chain & Cost Structure: Reduced overall manufacturing costs by 15% (compared to full in-house production) by outsourcing structure manufacturing and system integration, and lowered internal production complexity and fixed asset investment risks.
Strengthened Brand Reputation: Successful delivery of the 150MW Hami, Xinjiang benchmark project further solidified the client's industry position as a leading equipment supplier.
"For that incredibly challenging Hami desert power station project, the end customer's requirements were extremely demanding. Without the strong support from ETENZ in high-performance enclosure structures and professional system integration, it would have been very difficult for us to meet all technical specifications and win the order within such a tight timeframe. Their professionalism, responsiveness, and quality control (especially the IP54 rain test and C5 anti-corrosion process) truly impressed us. They are a trustworthy strategic partner."
