Established in 2010, Shenzhen Grenergy Technology Co., Ltd. is a recognized national high-tech enterprise specializing in the R&D, engineering, and manufacturing of premium lithium-ion batteries, smart Battery Management Systems (BMS), and vertically integrated home energy storage solutions. Over the past decade, we have dedicated ourselves to transforming renewable energy distribution by producing highly customizable, safe, and efficient power systems for residential, commercial, and emergency utility applications worldwide.
From design prototyping to high-volume automated manufacturing, our facilities support end-to-end OEM and ODM customized services. Whether you require customized mechanical enclosures, tailored cell configurations, or communication integration for local grids, Grenergy has the technical expertise to elevate your brand.
Decentralized energy distribution is no longer a concept—it is a critical modernization requirement. High global utility prices, carbon neutral mandates, and dynamic grid structures drive consumer demand for robust energy backup.
Maximizing the utilization of locally generated solar energy. With the declining rates of Feed-in Tariffs (FiT), storing excess PV energy during peak sunlight hours is the key driver of residential grid independence.
Enabling home systems to interact with regional grids. Dynamic electricity markets demand smart bidirectional charging protocols, facilitating passive income through grid peak shaving.
Protecting homes against blackouts caused by extreme weather conditions. The demand for sub-10ms automatic transfer switching (ATS) systems ensures continuous operation of critical home loads.
Different geographic markets present distinct grid demands, safety regulations, and configuration requirements. Grenergy customizes solutions for various environments:
For US and Canadian installations, residential power lines typically require split-phase output configurations (120V/240V). Grenergy’s custom OEM systems integrate seamless low-frequency inverters and autotransformers to support split-phase balancing without additional hardware.
In Germany, Central Europe, and the UK, three-phase grid topology is standard. Our high-voltage stacked systems (up to 400V+ nominal DC) reduce line losses, enhance efficiency, and integrate with hybrid inverters (SMA, Fronius, Sungrow) via Modbus RTU/CAN protocol mapping.
From remote cabins in Northern Europe to off-grid farms in Australia, we customize battery packs with integrated thermal management jackets, allowing operational stability from -20°C to +55°C.
Over the years, 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.
As a future-proof OEM manufacturer, Grenergy is expanding its engineering scope beyond current LFP (Lithium Iron Phosphate) tech boundaries:
Grenergy's manufacturing advantage is built on the global power electronics capital: Shenzhen, China. This industrial ecosystem allows us to achieve cost and timeline efficiencies unmatched in Western markets:
Vertical Integration of Raw Materials: We have direct strategic alliances with top-tier mineral suppliers and cell-core chemical manufacturers. This raw-material stability buffers our OEM clients from pricing spikes in lithium carbonate, ensuring stable contract pricing.
Complete Battery Accessory Sourcing Ecosystem: Components ranging from high-precision BMS circuit boards, customized metal casings, and liquid cooling channels are sourced and processed within a 50km radius, reducing development turnaround to weeks instead of months.
Agile Shipping & Logistics Hub: Proximity to major global deep-water ports (Shenzhen Port, Hong Kong Port) allows for the safe and compliant transport of Class 9 dangerous goods (UN3480).
Compliance and safety are critical to energy storage imports. Grenergy maintains rigorous quality control procedures certified to international standards.
Our products meet international certification standards, earning credentials such as ISO9001, ISO14001, ISO45001, UL1973, UL9540A, CE, FCC, PSE, and UN38.3. Our certifications guarantee compliance with stringent utility grid codes across North America, Europe, Australia, and Asia.
For peace of mind, we provide a $3 Million USD third-party product liability insurance policy on all items, protecting your business, operations, and installers against unforeseen electrical or system events.
Through localized distribution support, we coordinate customs clearances and offer technical compliance documentation, easing the path to market for local brands.
We are proud to have partnered with some of the world’s leading organizations and technology providers. These collaborations help us bring the latest advancements in energy storage and management systems to market, providing our clients with the most efficient and innovative solutions available.
Don’t just take our word for it—our clients trust us to provide safe, high-performance energy storage systems that meet their needs. With global customers from various industries, including renewable energy, manufacturing, and transportation, we have built a reputation for delivering reliable, top-quality products.
"Partnering with Grenergy for our residential solar battery launch in Europe was a major milestone for our business. Their technical team customized the CAN bus communication to work with our existing inverter systems, and the UL certifications sped up our market launch by months."
- Chief Technology Officer, European Energy Solutions IntegratorWe offer comprehensive OEM/ODM customization services. This includes customized metal enclosures (wall-mounted, floor-mounted, or server-rack), tailor-made Battery Management Systems (BMS) with specific communication protocols (CAN, RS485, Modbus RTU, Wi-Fi, Bluetooth), specific C-rate charging options, and branding/private labeling solutions.
Our intelligent BMS protocols are pre-integrated and compatible with leading global inverter brands, including Victron Energy, Growatt, Solark, Deye, SMA, Studer, GoodWe, and Sofar. Communication protocols can be configured at the factory level to match your specific inverter requirements.
We use high-grade A-class Lithium Iron Phosphate (LiFePO4) chemistry, which provides over 6000 cycles at 80% Depth of Discharge (DOD). Standard designs carry a comprehensive 5 to 10-year warranty, backed by our $3 Million USD product liability insurance policy.
Yes, all our systems undergo rigorous regulatory testing. We hold international safety and transport certifications, including ISO9001, ISO14001, ISO45001, CE, FCC, UL1973, UN38.3 (battery transport safety), and MSDS documentation. This ensures seamless customs clearances and regulatory compliance.
MOQ requirements vary based on the level of engineering customization needed. For baseline white-labeled products, we support low MOQs to help partners test their local markets. For deep mechanical or electrical engineering customizations, please contact our engineering division directly.
