At the heart of the BAT-HV-S Series is its high-voltage architecture, a key differentiator that elevates efficiency and performance compared to low-voltage alternatives. Each model is engineered with a tailored operating voltage range: the BAT-15K-HV-S operates at 134.4–168.48V, the BAT-20K-HV-S at 179.2–224.64V, the BAT-25K-HV-S at 224–280.8V, and the BAT-30K-HV-S at 268.8–350.4V. This high-voltage design minimizes current loss during energy transmission, reducing heat generation and improving overall system efficiency—critical advantages for both daily use and long-term durability. The series maintains consistent charging and discharging performance across all models: a 50A recommended charge current ensures fast replenishment from solar panels or the grid, while a 100A maximum continuous charge/discharge current delivers robust power to support high-wattage household appliances, including electric stoves, HVAC systems, electric vehicle chargers, and home office equipment.
Modularity is the defining feature of the BAT-HV-S Series, enabling homeowners to start small and scale up as their energy needs grow. Each system is constructed from 3 to 6 standardized 5.12kWh lithium iron phosphate (LiFePO4) battery modules (51.2V 100Ah per module), with the BAT-15K-HV-S (15.36kWh) using 3 modules, the BAT-20K-HV-S (20.48kWh) using 4, the BAT-25K-HV-S (25.6kWh) using 5, and the BAT-30K-HV-S (30.72kWh) using 6. Beyond individual system scalability, the series supports up to 4 parallel units, allowing a total storage capacity of up to 122.88kWh—enough to power an entire home for days during extended grid outages or to maximize self-consumption of solar energy for off-grid living. This flexibility makes the BAT-HV-S Series a future-proof investment, adaptable to changing household sizes, energy usage patterns, or the addition of more solar panels.
Durability and longevity are embedded in every aspect of the BAT-HV-S Series, starting with its premium LiFePO4 cell technology. Unlike conventional lithium-ion batteries, LiFePO4 cells are inherently safe, non-flammable, and resistant to thermal runaway—critical for indoor installation. The series boasts an impressive cycle life of 6,000 cycles at 80% depth of discharge (DOD), translating to over 15 years of reliable operation for the average household (based on one full charge/discharge cycle per day). This exceptional lifespan is further enhanced by a wide operating temperature range: the system charges efficiently between 0°C and 55°C and discharges reliably from -20°C to 60°C, making it suitable for climates with extreme winter cold (e.g., Northern Europe, Canada) or sweltering summer heat (e.g., Southern Europe, Australia). The IP65 protection rating shields the system from dust and water ingress, while a 5%–95% relative humidity tolerance ensures stability in humid environments, from coastal regions to tropical climates.
Design and usability are prioritized to ensure seamless integration into residential spaces. All models share a compact, stackable form factor with uniform dimensions (610×255×1390mm), making installation easy in garages, utility rooms, or basements—even in limited spaces. The weight scales proportionally with capacity: 170kg for the BAT-15K-HV-S, 223kg for the BAT-20K-HV-S, 275kg for the BAT-25K-HV-S, and 329kg for the BAT-30K-HV-S, with individual modules (high-voltage box: 610×225×250mm, 16kg; battery box: 610×225×250mm, 48.5kg) lightweight enough for easy handling during installation or maintenance. Natural air cooling eliminates the need for noisy, high-maintenance fans or liquid cooling systems, ensuring silent operation that blends seamlessly into home environments. A clear on-board display provides real-time battery status, including state of charge (SOC), voltage, and other critical metrics, keeping homeowners informed without the need for complex monitoring software.
Connectivity and compatibility are key strengths of the BAT-HV-S Series, with CAN and RS485 communication interfaces enabling seamless integration with solar inverters, smart home energy management systems (EMS), and remote monitoring platforms. These protocols allow for real-time tracking of energy flow (solar input, battery storage, grid export/import), automated load shifting (prioritizing battery power during peak grid tariff hours), and remote firmware updates to keep the system optimized. Whether paired with a rooftop solar array to maximize renewable energy usage, or as a standalone backup power source, the BAT-HV-S Series integrates effortlessly with existing home energy systems, reducing reliance on fossil fuel-based grid power and lowering electricity bills.
Safety and compliance are non-negotiable for the BAT-HV-S Series, which adheres to global industry standards and certifications (CAN/RS485 compliant). The IP65 protection rating, robust temperature tolerance, and LiFePO4 cell safety features ensure compliance with residential electrical codes worldwide, while the system’s natural cooling design and low heat generation minimize fire risks. For installers and homeowners alike, this compliance provides peace of mind, knowing the system meets the strictest safety and performance standards across Europe, North America, Australia, and beyond.
Beyond technical performance, the BAT-HV-S Series aligns with the global shift toward sustainable energy. By storing excess solar energy generated during the day for use during peak demand hours or grid outages, it reduces reliance on fossil fuels, cuts household carbon emissions, and enhances energy security. Its long cycle life also minimizes waste, as the system requires replacement far less frequently than traditional lead-acid batteries, contributing to a circular economy and reducing environmental impact.
In summary, the BAT-HV-S Series High-Voltage Stackable Residential Energy Storage System combines modular scalability, high-voltage efficiency, LiFePO4 durability, and user-centric design into a comprehensive solution for modern homeowners. Whether you aim to reduce energy costs, achieve grid independence, or ensure backup power during outages, the BAT-HV-S Series offers a flexible, reliable, and long-lasting solution that adapts to your needs today and tomorrow. Backed by premium materials, global compliance, and engineering excellence, it is more than a battery—it is a cornerstone of a smarter, more sustainable home energy ecosystem.
