Why us

 

Fully Integrated In-House Supply - No More Piecemeal Sourcing

We provide complete solutions for PV power plants and energy storage systems, covering solar PV modules, storage batteries, power conversion systems (PCS), battery management systems (BMS), energy management systems (EMS), and all related electrical equipment. Unlike copycats who only mimic appearances, we design and supply virtually all core components ourselves, eliminating the complexity of coordinating multiple vendors.

Both System Integrator and Original Manufacturer

We are not only a professional system integrator for PV and storage solutions - crucially, we also manufacture most core components in-house. This means our customers enjoy both one-stop system-level service and the cost advantages and quality assurance that come from working directly with the original factory. We completely avoid the double trap that imitators create: middleman markups and outsourced core components.

Vertically Integrated Manufacturing - Control Over Quality and Cost

From battery cells (or battery packs), BMS, and PCS to mounting structures and distribution cabinets, we insist on in-house production of core components. This vertical integration allows us to control product consistency and reliability from the source, while passing cost optimizations directly to our customers - a fundamental advantage that copycats cannot replicate.

Over a Decade of Technical Expertise - Beyond Surface Imitation

Since 2012, we have accumulated extensive experience in power electronics, battery pack engineering, and system integration. Unlike vendors who only mimic appearances or perform simple assembly, we possess proven expertise and a large portfolio of real-world projects in core areas such as battery thermal management, system protection strategies, and energy scheduling algorithms.

Professional R&D Team - Continuous Innovation

Our R&D team of over 60 engineers collaborates closely with the PV Institute of Fudan University and Shenzhen Foxconn, continuously advancing key technologies in energy storage systems, PV inverters, and intelligent control. We hold more than 20 national patents and operate under our own brand, LUYOU. Our technological strength is far beyond what imitators can achieve.

Large Factory with Full In-House Production and Testing Capabilities

Our 6,000 facility is staffed by a team of 400. We are equipped with battery pack assembly lines, PCS test benches, aging test systems, charge/discharge testers, insulation withstand voltage testers, and more. From cell sorting to final system assembly, every step is performed and rigorously tested in-house, eliminating the quality fluctuations that imitators experience through outsourced manufacturing.

Transparent Cost - No Middleman Markups

By manufacturing core components in-house and optimizing overall costs through scale and system-level integration, we offer competitive pricing without compromising quality. As an original manufacturer, we sell directly to customers with no middleman markups. Additionally, our system integration capability further reduces customers' total cost of ownership (TCO) - a structural advantage that copycats cannot replicate.

One-Stop Solutions for Residential, C&I, and Utility-Scale Storage

We offer a complete product matrix for PV and energy storage, covering:
1.Residential Storage: All-in-one PV storage systems for homes and small commercial applications
2.Commercial & Industrial (C&I) Storage: Modular energy storage systems for factories, industrial parks, shopping malls, and other commercial sites
3.Utility-Scale Storage: Containerized energy storage systems for grid-side, generation-side, and large-scale commercial projects
Regardless of project size, customers receive consistent technical support and service guarantees.

Our Services

Clear Warranty - No Empty Promises

YANGDE guarantees that its PV modules, storage batteries, and energy storage systems will be free from defects in materials and workmanship for a period of two (2) years from the date of purchase. We provide clear repair or replacement policies, in contrast to copycats who often make verbal promises but offer little after-sales support. For storage batteries, we can also offer additional warranty terms based on cycle life.

Professional System Design and Integration Services

Based on each customer's actual electricity demand, solar irradiation conditions, and application scenario (residential / C&I / utility-scale), we provide customized PV storage system designs. From capacity planning, equipment selection, to system integration, every step is handled by our professional engineering team to ensure optimal system efficiency and safety.

Installation Guidance and On-Site Technical Support

We provide detailed installation instructions, electrical wiring diagrams, and commissioning videos. For commercial & industrial and utility-scale storage projects, our technical team can provide on-site installation guidance, system commissioning, and grid connection support free of charge to ensure smooth project deployment.

Spare Parts Included - Reducing Maintenance Pressure

Based on the transaction amount, we provide 0.5% to 1% of key spare parts (including battery modules, BMS boards, PCS modules, control units, etc.) free of charge. This helps customers establish an initial spare parts inventory, avoiding the difficulty of sourcing parts from copycats who often lack spare part support.

After-Sales Support and Lifetime Service

We provide lifetime technical support and repair services for our PV storage systems. Any questions or issues raised by customers will be responded to within 24 working hours. Additionally, we can provide remote monitoring and maintenance support (requires compatible EMS system) to help customers monitor system performance in real time.

Recommended Maintenance to Extend System Life

Although our PV storage systems are designed for high reliability, the following routine maintenance is recommended:
1.Monthly: Check system operating data via the monitoring platform (if available), paying attention to key parameters such as battery voltage, temperature, and state of charge (SOC).
2.Quarterly: Inspect battery connection terminals for looseness, clean dust from equipment surfaces, and ensure proper ventilation and heat dissipation.
3.Semi-Annually: Perform battery balancing maintenance (depending on BMS functionality) and check the operating status of the PCS and distribution equipment.
4.Every 3 to 5 Years: Evaluate whether additional or replacement battery modules are needed based on battery degradation, ensuring system capacity continues to meet operational requirements.

ODM & OEM Customization Services

We have complete in-house capabilities from battery cell packaging, BMS development, PCS design, to full system integration. We provide ODM and OEM services for PV storage products. Unlike copycats who simply add a label, we help customers create truly differentiated, cost-effective energy storage products with solutions built from the ground up.
