With a strong commitment to technological innovation, Grenergy has become a leading provider of energy solutions for various applications worldwide.
Leveraging over a decade of chemical engineering and assembly automation, we deliver cutting-edge OEM/ODM options to tier-1 distributors globally.
Understanding the shift in smart cells, solid-state integration, and multi-protocol hardware.
Compact power stations have transitioned from volatile NCM mixtures to high-density, safety-optimized Lithium Iron Phosphate (LiFePO4) frameworks. Offering over 3000 to 6000 cycles at 80% DOD, LFP is the default standard for long-term commercial applications.
Global electrical grid compatibility requires integrated smart inverters. Modern ODM architectures must support pure sine wave output, auto-switching UPS functionality (<10ms), and direct integration with photovoltaic solar controllers (MPPT).
AI-monitored active cooling, state-of-the-art heat sink designs, and self-extinguishing battery cell casings work to minimize the risk of thermal runaway, making compact units safe for indoor, home, and transit use.
Enterprise buyers, industrial developers, and hardware brands demand more than simple branding. B2B procurement strategies are increasingly focused on supply chain visibility, component traceability, and comprehensive engineering support. As compact power generators move from leisure outdoor activities to emergency home backup systems and remote operations, buyers look for structural modularity, app-enabled control units, and customized high-voltage options.
Additionally, custom battery enclosures must withstand drops, UV degradation, and water ingress. High-performance portable batteries, like the 51.2V rack-mounted frameworks or trolley systems, require extensive structural analysis to ensure they remain functional in demanding field environments.
Since its establishment, Grenergy has focused on the development of sustainable energy solutions to meet the growing demand for efficient, reliable, and eco-friendly power systems. With over 10 years of expertise, Grenergy has developed a diverse product portfolio, including Lead-acid replacement lithium batteries, Wall-mounted power walls, Portable power stations, Mobile home energy storage systems, Trolley box portable power stations, and much more. We are committed to enhancing energy efficiency while reducing environmental impact.
Our core values include integrity, innovation, and customer satisfaction, which have been the foundation of our growth. Grenergy’s history is one of continuous improvement and dedication to providing advanced energy storage solutions to businesses and individuals globally.
Grenergy’s products support various OEM and ODM customized services, allowing us to tailor solutions that meet specific client needs. With nearly 10,000 square meters of production space and a team of 200 highly skilled professionals, we are equipped to deliver high-quality products at scale. Over the years, we have consistently met international industry standards, earning certifications such as ISO9001, ISO14001, ISO45001, UL, CE, FCC, PSE, and UN38.3.
We also provide third-party product liability insurance worth $3 million USD for all products, ensuring our global clients can trust our reliability and commitment to service excellence.
China dominates the global battery supply chain, accounting for over 70% of global battery manufacturing capacity. For international purchasers looking for custom compact power stations, partnering with a Chinese supplier like Grenergy provides access to a complete upstream and downstream network. From raw lithium processing to cell manufacturing, advanced active balancing BMS engineering, and automated testing, every component of the production cycle is optimized for efficiency and quality.
| Procurement Metric | Regional Sourcing (US/Europe) | Shenzhen Grenergy Supply Chain |

"Grenergy's ODM design process transformed our outdoor backup system lineup. Their in-house testing facility resolved our compliance challenges in Europe and Japan, cutting our launch timeline by three months."
— Procurement Director, European Off-grid Solar Brand
From initial design to final output, our products undergo rigorous testing. Operating under ISO9001, ISO14001, and ISO45001 standards, our production lines are equipped with automated cell sorters, high-precision laser welders, and computerized aging systems that subject every power station to simulated multi-climate cycles.
We conduct real-time structural analysis and check for defects before, during, and after assembly. Every circuit is checked by advanced optical machinery, ensuring that trace elements in the BMS function reliably when operating under load.
Essential compliance and design insights for international B2B purchasers.
These certifications ensure your products comply with local import laws and are safe to sell. Specifically, UL 2743 governs portable power systems in North America, while UN38.3 is mandatory for shipping lithium battery configurations safely by air or sea.
Custom ODM developments typically take 3 to 6 months. This timeline covers industrial styling (ID), hardware design, firmware adjustments, molding, safety testing, and pre-production certification.
We configure the electronics in our systems to match local electrical grids. This includes adjusting AC voltage (110V/230V), frequency (50Hz/60Hz), and using regional outlet styles (US, EU, UK, AU, Universal) to ensure out-of-the-box compatibility.
We back all products with a comprehensive factory warranty and a $3 million USD product liability insurance policy, giving your brand extra security in competitive international markets.
MOQ ranges from 100 to 500 units depending on the size and complexity of the system. For simple color changes or logo printing on standard models, we can offer more flexible lower limits.
