CNLONQ Delivers Full PV Electrical Solution Package for 200MW Gobi Solar Project in Saudi Arabia
Date:7/13/2026 11:04:05 AM Click:8
CNLONQ has officially completed the delivery of a full suite of DC-side electrical equipment for the 200MW Gobi photovoltaic power plant project in Riyadh, Saudi Arabia. As a key energy initiative under Saudi Arabia's Vision 2030, the project marks another milestone in CNLONQ's overseas expansion. As the core electrical solution provider, CNLONQ supplies the full spectrum of PV DC-side products, including smart combiner boxes, MC4 connectors, DC circuit breakers, and SPD surge protectors, ensuring the safe and efficient operation of the solar plant through an integrated one-stop solution.
Project Background: Extreme Gobi Conditions Demand Robust Equipment Performance
Located in the Gobi Desert region east of Riyadh, the 200MW solar project spans approximately 600 hectares and forms a critical component of Saudi Arabia's National Renewable Energy Program (NREP). The site's persistent high temperatures, strong sandstorms, wide diurnal temperature variations, and high lightning strike risk impose stringent requirements on the protection rating, weather resistance, and operational reliability of outdoor electrical equipment.
Comprehensive Solution: Four Core Products Engineered for Extreme Gobi Environments
Tailored to the complex conditions of the Saudi Gobi, CNLONQ has developed a full DC-side electrical solution for the project. Four core product categories work in synergy to build a robust defense for the safe and stable operation of the solar plant:
- IP65 Industrial Protection: Fully sealed enclosure design certified under stringent dust and water ingress tests, effectively blocking Gobi sand and dust from penetrating internal components
- Wide Temperature Range Design: Core components rated for -40°C to 85°C operation, fully adaptable to extreme high-temperature environments exceeding 50°C
- Smart Monitoring Function: Integrated current sensing and RS485 communication enable real-time per-channel current monitoring, fault localization, and remote alarm, significantly reducing O&M costs in remote Gobi locations
- Tin-Plated Copper Terminals: High conductivity with low contact resistance, operating temperature rise below industry standards, suitable for high-current, high-load scenarios
- UL94-V0 Flame-Retardant Housing: High-strength engineering plastic with UV resistance and anti-aging properties, delivering over 25 years of service life under intense Gobi UV exposure
- IP67 Waterproof and Dustproof: Multi-layer sealing structure with locking mechanism ensures reliable connections and stable insulation performance even in sandy environments
- DC1500V High-Voltage Breaking Capacity: Dedicated DC arc extinguishing system reliably interrupts DC fault currents, eliminating arc flash and fire risks
- High-Temperature Trip Characteristic Optimization: Calibrated bimetallic trip curves prevent false tripping or failure-to-trip under high-temperature conditions, ensuring continuous plant operation
- DIN Rail Quick Installation: Standardized mounting dimensions compatible with various combiner box enclosures for convenient on-site installation
- 20kA High Discharge Capacity: Multi-stage lightning protection design effectively dissipates induced overvoltage from Gobi thunderstorms, safeguarding downstream inverters and modules
- Thermal Trip Failure Indicator: Built-in overheat protection automatically disconnects from the grid upon failure with visual indication, simplifying O&M inspection
- Remote Alarm Interface: Supports remote status monitoring, enabling real-time lightning protection status tracking when integrated with the combiner box smart system
Delivery Assurance: One-Stop Supply Localized Service for On-Schedule Grid Connection
Leveraging its synergistic product portfolio advantage, CNLONQ achieves unified production scheduling, consolidated shipping, and one-stop delivery for combiner boxes, connectors, circuit breakers, and surge protectors, significantly reducing customer procurement and management costs. The company has also activated its Middle East rapid response mechanism, optimizing shipping and customs clearance processes to compress the overall delivery lead time to 80% of the industry average.
On-site, CNLONQ deploys a team of senior electrical engineers to provide full technical support, covering installation guidance, commissioning training, and O&M solution development, empowering local construction teams to quickly master full equipment operation and maintenance. This embodies CNLONQ's deep-market expansion philosophy of "product export technology empowerment localized service."
Strategic Significance: From Single Products to Full Solutions, Building China's PV Electrical Brand
This project represents another landmark application of CNLONQ's full PV electrical solution package in large-scale overseas ground-mounted solar plants, marking the company's strategic upgrade from a single equipment supplier to a comprehensive electrical solution provider. To date, CNLONQ's PV electrical products — including combiner boxes, MC4 connectors, DC circuit breakers, and SPD surge protectors — have been exported to over 50 countries and regions worldwide, with a cumulative installed capacity exceeding 30GW.
A representative from CNLONQ's Overseas Business Division stated: "The successful delivery of the 200MW Saudi project is an important milestone for CNLONQ in deepening the Middle East market and advancing our full-category overseas expansion strategy. Going forward, we will continue to increase R&D investment and overseas market presence, delivering safe and reliable full PV electrical solutions with localized services, partnering with global customers to build a greener, low-carbon future, and contributing Chinese expertise to Belt and Road energy cooperation."
