In recent years, extreme weather, aging infrastructure, and soaring grid electricity tariffs have made household energy self-sufficiency a top priority for global consumers. Under the umbrella of net energy metering policies, such as California’s Net Billing Tariff (NEM 3.0) and Europe's feed-in tariff revisions, storing solar energy for peak-hour self-consumption has yielded much higher economic returns than exporting it back to the grid.
For distributors, installers, and project integrators across North America, the EU, Australia, and South Africa, securing a reliable, tier-1 qualified Home Solar Energy Storage System Factory is essential to address this massive transition. Home energy storage has transformed from a niche off-grid solution into a fundamental element of real estate optimization and virtual power plant (VPP) networks.
China remains the unmatched global powerhouse for lithium battery and complete energy storage system (ESS) manufacturing. By leveraging a highly integrated local supply chain spanning raw lithium refinement, cathode material synthesis, smart battery management system (BMS) design, and automated pack assembly, Chinese factories offer an unbeatable cost-performance ratio.
Furthermore, this concentrated infrastructure dramatically reduces the research-to-production cycle for OEM and ODM customization. Instead of dealing with disparate vendors, international buyers can procure custom high-density rack-mounted units, installer-friendly wall-mounted batteries, and high-performance portable power stations directly from a single specialized manufacturer.
Established in 2010, Shenzhen Grenergy Technology Co., Ltd. is a high-tech enterprise specializing in the R&D, production, and worldwide shipping of lithium batteries, energy storage systems, power batteries, and comprehensive all-in-one backup solutions. Over the last decade, we have established ourselves as an industry-leading OEM and ODM partner for clients across the globe.
Our comprehensive portfolio features state-of-the-art Lead-acid replacement lithium batteries, wall-mounted power walls, portable power stations, modular home energy storage solutions, and heavy-duty trolley box portable backup systems. By utilizing advanced safety architectures and smart BMS monitoring, we ensure that every system delivers optimum efficiency while minimizing environmental impact.
Operating from nearly 10,000 square meters of highly automated production space, and supported by a team of over 200 skilled engineers and quality inspectors, Grenergy operates with unmatched scalability and meticulous care. All incoming raw materials, structural frames, and electronic component assemblies undergo multi-layer QC validation.
Recognizing that system safety is a non-negotiable metric for residential energy storage systems, Grenergy provides a comprehensive $3 Million USD Third-Party Product Liability Insurance for our entire product catalog. This major safety and economic safeguard ensures our global wholesale and distribution partners can scale their business operations with complete peace of mind.
Our systems are engineered around Lithium Iron Phosphate (LiFePO4) cell chemistry. Recognized for its excellent thermal stability, extended lifecycle, and ecological footprint, LiFePO4 serves as the gold standard for high-performance home solar energy storage.
Unlike traditional NCM chemistry, which poses risks of thermal runaway under mechanical stress, LiFePO4 retains structural integrity up to 600°C. This makes it an ideal energy cell for residential installations close to living quarters.
Each Grenergy battery pack features an advanced built-in BMS tracking cell temperature, balance voltage, charge/discharge rates, and state of health (SoH). This integration maximizes system longevity up to 6,000 deep cycles.
Our high-voltage floor and rack-mounted batteries are configured with CAN, RS485, and RS232 protocols, enabling seamless plug-and-play integration with mainstream hybrid inverters from Growatt, Deye, SMA, Sofar, and Victron.
Since our inception in 2010, Grenergy's core mission has been to accelerate the replacement of toxic, inefficient lead-acid batteries with safe, smart lithium energy systems. By bridging the gap between state-of-the-art Chinese manufacturing efficiencies and local compliance standards, we empower families and grid operators to harness solar energy with complete reliability.
Grenergy maintains strategic collaborations with top tier-1 cell fabricators, electronic component suppliers, and certification institutions. These technical alliances allow us to offer leading-edge hardware iterations and firmware modifications, helping custom installers and distributors gain a competitive edge in their local markets.
No single solar energy storage layout fits all markets. Grenergy specializes in tailored configurations for specific residential, transport, and off-grid scenarios:
Engineered with space-saving requirements in mind, our wall-mounted power walls integrate seamlessly into residential garages or utility rooms, matching standard hybrid systems to offset peak load charges.
Ideal for motorhomes, yachts, and remote field camps. Heavy duty 12.8V 300Ah packs replace conventional dual lead-acid setups, offering three times the usable energy at half the weight.
Featuring rugged, heavy-duty wheels, telescopic pull-bars, and multi-port AC outputs, our mobile trolley stations are ideal for rescue operations, outdoor clinics, and mobile film production crews.
"By partnering with Grenergy for our custom 5kWh LiFePO4 battery enclosures, our installer network across Europe reduced setup times by 40%. The plug-and-play communication with our hybrid inverters worked flawlessly right out of the box."
— VP of Operations, German Renewable Energy Integration Company
"Grenergy's $3 Million USD product liability coverage provided the security our legal division required. Combining that insurance with their rigorous UL and CE certifications made choosing them as our main ODM factory an easy decision."
— Procurement Manager, American Commercial Solar Distributor

LiFePO4 (Lithium Iron Phosphate) offers significant safety and longevity benefits compared to NCM (Nickel Cobalt Manganese). LiFePO4 exhibits thermal stability up to 600°C, virtually eliminating the risk of thermal runaway and self-combustion, making it far safer for residential indoor installations. Additionally, LiFePO4 systems deliver an exceptional lifespan, maintaining over 80% capacity even after 6,000 deep cycles (at 80% depth of discharge), whereas NCM batteries typically degrade after 1,500 to 2,000 cycles. LiFePO4 is also cobalt-free, representing a more environmentally sustainable and ethically sourced option.
Product liability insurance is a critical risk-mitigation tool for international B2B distributors and engineering procurement contract (EPC) companies. In the unlikely event of system malfunction, electrical failure, or property damage resulting from battery integration, our third-party global insurance policy covers losses up to $3 million USD. This reduces the risk profile of importing products from China, shielding your distribution brand from costly lawsuits and liability disputes in your home territory.
Yes. Our dedicated in-house R&D team can customize communication protocols on the BMS (Battery Management System). We pre-program communications via CAN, RS485, and RS232 protocols to match the exact requirements of your preferred local inverter brands (such as Growatt, Deye, SMA, Victron, and Megarevo). During the ODM design phase, you simply provide the protocol sheet of the target inverter, and our firmware team will configure and test compatibility before mass production.
We maintain a complete array of international certifications required for smooth customs clearance and utility grid approval. Our home energy storage solutions carry UL 1973, UL 9540A (for the US and Canada), CE, IEC 62619, and EN 61000 (for European markets). For global maritime, air, and land transportation compliance, all our battery shipments are fully backed by MSDS and UN38.3 test documentation.
We offer comprehensive design and engineering customization services. Clients can customize voltage parameters (ranging from 12.8V up to high-voltage 51.2V setups), capacity ratings (ranging from 100Ah up to 314Ah), and form factor styles (including sleek wall-mounted profiles, modular floor-mounted cabinets, standard rack installations, and portable trolley cases). Furthermore, we can customize shell designs with custom branding, specific powder coatings, customized LCD interface panels, and specific IP ratings (such as IP65 for outdoor installation).
