High-efficiency, long cycle life, and fully certified battery products designed for industrial, residential, and mobile energy needs.
Shenzhen Grenergy Technology Co., Ltd., established in 2010, is a high-tech enterprise specializing in R&D and manufacturing lithium batteries, energy storage systems, power batteries, battery management systems, and all-in-one solutions. With a strong commitment to technological innovation, Grenergy has become a leading provider of energy solutions for various applications worldwide.
In the modern era of the global energy shift, global procurement for utility-scale and portable power stations is undergoing a profound structural evolution. Procurement managers at major energy and shipping conglomerates are no longer simply examining basic output metrics. In order to optimize the Levelized Cost of Storage (LCOS), companies now demand comprehensive energy efficiency, system stability, thermal safety protocols, and supply-chain track records.
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. By positioning our production paradigms at the intersection of material science and mechanical engineering, we deliver systems engineered for multi-decade operations.
Modern commercial infrastructure demands diverse modular topologies for power integration. Standardizing power stations for high-stress applications requires rigorous tailoring. Grenergy addresses these macro-level needs through specific technological clusters:
Utilizing high-capacity 51.2V rack-mounted and floor-mounted systems to offset grid dependency during peak tariff hours, shifting loads to optimize operating expenses.
Deploying ultra-stable, high-density LFP rack modules with low latency transfer limits, preventing packet loss and hardware downtime during local utility failure events.
Coupling 5kWh to 30kWh residential wall batteries with PV arrays to yield full energy autonomy, leveraging intelligent BMS software for zero-export configurations.
In addition to static energy assets, modern industries demand mobile high-capacity electrical setups. High-voltage lithium battery solutions (such as 76.8V for utility vehicles and golf carts) offer significant power density, lower thermal profiles, and virtually zero maintenance overhead. Similarly, marine and RV fleets require optimized, lightweight 12.8V deep-cycle batteries to run life-support, communication, and refrigeration electronics. These demands underscore why procurement professionals focus on specialized suppliers who understand vehicular dynamics, shock/vibration resilience, and dust/water-ingress protection ratings.
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. This high financial backing guarantees security for EPC contractors and municipal energy departments dealing with grid-scale projects.
From the beginning, Grenergy’s mission has been to empower the world with cutting-edge energy storage solutions.

In search of maximizing life cycles while minimizing the footprint of electrical components, Grenergy leverages advancements in chemistry and battery design. Below is our engineering approach to modular energy design:
Compared to Lithium Nickel Manganese Cobalt Oxide (NMC) chemistries, LiFePO4 offers unmatched thermal runaway thresholds (up to 270°C compared to 150°C for NMC). This makes LFP inherently safe for residential homes and densely populated industrial zones. Additionally, LFP boasts a deep cycle life of over 6,000 charge/discharge cycles at 80% Depth of Discharge (DoD), drastically reducing total lifecycle costs compared to lead-acid batteries, which typically degrade within 500 cycles.
Every cell array is monitored by a proprietary BMS system. The system performs active and passive cell-balancing algorithms to ensure uniform state of charge (SoC) across the module pack. Features include:
Grenergy packages these cells in varied mechanical form factors to accommodate diverse spatial footprints. Wall-mounted designs save valuable floor space in residential setups, while server-rack enclosures utilize standard industrial racking for high-capacity C&I deployments. For mobile sites, portable trolley-style designs incorporate rugged wheels and high-capacity pure sine wave inverters (up to 2500W AC outputs) to handle power tools, medical equipment, and emergency communications under harsh conditions.
For B2B distributors and importers, importing complex electrical equipment presents strict regulatory challenges. Grenergy solves this by adhering to a comprehensive international certification matrix:
Certified ISO9001 (Quality Management), ISO14001 (Environmental Standards), and ISO45001 (Occupational Health & Safety) to ensure systematic production consistency.
UL, CE, FCC, and PSE certifications verify that our electrical products pass rigorous fire, short-circuit, and operational shock tests.
UN38.3 compliance confirms that our batteries safely withstand extreme vibrations, altitude pressures, and thermal impacts during ocean and air transit.
Operational stability is not only an engineering concern; it is also a commercial risk. Grenergy provides a third-party product liability insurance policy valued at $3 million USD. This security ensures that utility managers, system integrators, and B2B distributors can install, distribute, and scale Grenergy energy storage systems with complete protection against unexpected operational liabilities. Combined with robust localized technical support, we guarantee project continuity and absolute peace of mind.
Critical answers for engineers, purchasing managers, and distributors seeking to partner with Tier-1 battery manufacturers.
Grenergy has over 10 years of manufacturing experience (since 2010), operating a high-tech facility spanning nearly 10,000 square meters. Our extensive R&D engineering focus, coupled with a $3 million USD product liability insurance policy and full ISO9001/ISO14001/ISO45001 certifications, offers commercial clients a unique blend of custom OEM/ODM capability and robust financial security.
51.2V is the industry standard for telecommunication base stations, data center UPS backups, and residential solar micro-grids. It offers an optimal balance between electrical safety standards (staying below extra-low voltage limits in many regions) and high capacity efficiency, minimizing line current losses during heavy-duty discharges.
LiFePO4 (Lithium Iron Phosphate) offers superior chemical and thermal stability. LFP does not suffer from thermal runaway under standard operations, contains no toxic heavy metals (like cobalt), and maintains over 80% of its original capacity even after 6000 cycles, providing a significantly lower total cost of ownership (TCO) than alternative chemistries.
Yes. Grenergy specializes in full ODM/OEM customization, including electrical sizing, BMS protocol optimization (such as customized CANbus parameters for specific inverters), structural casing modifications (wall-mounted, floor-mounted, or trolley housings), and customized brand branding.
All products are certified under UN38.3 safety testing, ensuring safe logistics through ocean freight, air transport, or road transit. Additionally, our batteries carry UL, CE, FCC, and PSE certifications for seamless entry through global customs frameworks.
