5th Generation Conversion Topology & Battery Engineering

Providing significant performance improvements for commercial and off-grid residential installations.

98.5% Inverter Efficiency

Equipped with 36 independent patents, our fifth-generation hybrid solar inverter achieves a peak conversion efficiency of 98.5%. This reduces thermal output and system losses, ensuring consistent performance in high-demand industrial systems.

LiFePO4 Chemistry

Our solar power walls (ranging from 30kWh to 60kWh configurations) utilize high-safety Lithium Iron Phosphate (LiFePO4) battery packs. These offer stable operation for over 6,000 charge cycles, helping lower the total cost of ownership (TCO) for off-grid operations.

Adaptive MPPT Control

Smart controllers match current output dynamically using high-speed Maximum Power Point Tracking (MPPT) algorithms. This minimizes efficiency losses due to shading, helping systems adapt to challenging environments.

Enterprise Procurement Capabilities

  • OEM & ODM Capabilities: Developed to support major retailers like Walmart and Home Depot.
  • Flexible Packaging: Options including customized metal enclosures and custom branding.
  • Reliable Freight Logistics: Organized to meet UN38.3 transport safety regulations.

B2B Sourcing, Global Supply Chains & Scale Production

For international procurers, sourcing off-grid solar equipment requires a balance of engineering quality, regulatory compliance, and consistent delivery. We offer flexible OEM/ODM services, supplying solar generator kits, portable power banks, and large-scale battery systems to major organizations globally.

Our custom workflows cover all project stages—from engineering design validation and electrical safety reviews to thermal chamber analysis. We maintain long-standing raw material partnerships to protect supply chains, allowing us to manage lead times and support large-scale rollouts.

With an annual capacity of 50,000 units, we help commercial clients transition away from fossil-fuel generators. This transition reduces operational expenses (OPEX) and supports long-term ESG and emissions targets.

Macro-Industry Clean Energy Solutions

Integrated setups designed to support commercial microgrids, remote facilities, and emergency power systems.

Industrial Commercial Storage (100kW – 215kW)

Designed for data centers, manufacturing centers, and large warehouses. These grid-scale solutions provide peak shaving, load balancing, and reliable backup power during grid instability, helping maintain continuous operation.

Off-Grid Power Walls (30kWh – 60kWh)

Designed for off-grid residences, remote telecommunication hubs, and agricultural projects. High-voltage lithium battery architecture pairs with local solar systems to store and deliver stable power when solar input is low.

Mobile Energy Storage (3kW – 10kW)

Rugged, compact generators designed for medical outreach, emergency response, and field work. Heavy-duty enclosures shield internal components from dust and moisture, ensuring reliable deployment in demanding field conditions.

Technology Development Roadmap: Target 2030

We continue to invest in battery research and development, focusing on high energy density, thermal safety, and recycled materials. Our active pipeline includes work on solid-state battery integration, aiming to increase energy density while keeping footprint minimal.

We are also working to optimize local system control through IoT and edge software integration. Integrating AI-enabled smart energy management (EMS) allows our generators to monitor weather patterns and historical use, adjusting charge and discharge cycles dynamically to help prolong system life.

As part of our commitment to environmental responsibility, Zhejiang Wenzhou New Energy Technology Co., Ltd. is working toward a Net-Zero Manufacturing Facility. We target a reduction of one million metric tons in global carbon emissions through our active systems by 2030.

Key Research Initiatives

Solid-State Cell Integration

Grid Connection & Support

Our hybrid inverters feature programmable charging profiles and parameter controls, allowing integration with varied grid codes across European, North American, and Asia-Pacific regions.

24/7 After-Sales Support

Supported by a global technical service network, we offer 24/7 multilingual support. We provide troubleshooting guidance and help optimize systems for industrial, commercial, and residential uses.

Frequently Asked Questions

Technical details and support information for partners, distributors, and procurement teams.

What customization options are available for OEM/ODM orders?
We offer comprehensive branding and hardware customization. This includes custom branding and logo integration, custom colors for metal enclosures, tailored input/output port configurations, and localized grid parameter presets. We also customize battery capacity sizing (from portable 120W models up to 215kW containerized setups) to match specific market demands.
How does Wenzhou New Energy maintain high battery cell quality?
We use A-grade Lithium Iron Phosphate (LiFePO4) cells sourced from established global suppliers. Every batch undergoes capacity screening, voltage balancing, and thermal chamber evaluation in our CNAS-certified laboratories. Our factory also integrates a production trace system to log test results for each serialized battery pack.
What safety certifications do your off-grid generators and power walls hold?
Our complete systems and battery sub-assemblies hold certifications including CE, RoHS, and UN38.3 transport compliance. We design systems to align with relevant safety standards (such as IEC 62619, UL 1973, and UL 9540A) to support project compliance in major export destinations.
How does the 5th generation hybrid inverter achieve 98.5% conversion efficiency?
Our 5th-generation inverter topology uses high-speed silicon carbide (SiC) semiconductor switches and optimized multi-phase circuit topologies. This helps minimize switching and conduction losses, allowing the system to achieve 98.5% conversion efficiency under standard test conditions.
What is your warranty policy, and how is after-sales support managed?
We provide warranties tailored to specific product categories: 5 years for off-grid battery power walls and up to 2 years for portable power units. To support commercial clients, we offer 24/7 multilingual technical assistance. Using our tracking system, we aim to resolve 90% of service inquiries within 2 hours.
