Powerwall LifePO4 Battery 48V 100Ah

51.2V 100Ah Wall-Mounted Lithium Battery for Home Energy Storage – Reliable, Scalable & Efficient

This high-performance 51.2V 100Ah lithium iron phosphate (LiFePO4) battery is a premium wall-mounted energy storage solution designed for residential solar systems and off-grid power backup. With a rated capacity of 5.12 kWh and an actual usable energy of 4.6 kWh, this unit ensures dependable electricity supply during outages or peak demand periods—ideal for powering essential household appliances such as lighting, refrigerators, TVs, and medical devices. Engineered for long-term reliability, it delivers up to 6,000 charge-discharge cycles at 90% depth of discharge (DOD), making it a durable investment for modern homes seeking sustainable energy independence.

Designed with a sleek, space-saving wall-mount configuration, this battery system eliminates floor space requirements while offering easy access for maintenance and monitoring. Its compact dimensions (580 x 390 x 185 mm) and lightweight build (~48 kg) make installation straightforward in garages, basements, utility rooms, or dedicated indoor cabinets. The IP21 protection rating offers basic dust and drip resistance, ensuring safe operation in typical indoor environments without condensation issues.

Key features include advanced safety certifications like UN38.3, IEC 62619, CE, UL1973, and UL2054, plus integrated BMS (Battery Management System) and circuit breaker protection against overcharge, over-discharge, short circuits, and temperature extremes. It supports scalable setups with up to 10 parallel units, allowing homeowners to expand their energy storage capacity as needs evolve. Communication interfaces such as RS232, RS485, and CAN bus enable seamless integration with inverters and smart energy management platforms, enhancing control and efficiency across solar photovoltaic installations.

Operating efficiently across a wide temperature range—from -10°C to +50°C for charging and -20°C to +50°C for discharging—the battery maintains optimal performance even in challenging climates. It’s suitable for use at altitudes up to 2,000 meters and humidity levels below 95% non-condensing conditions, making it adaptable to diverse global residential settings beyond China and its territories.

Perfect for households aiming to reduce grid dependency, maximize solar self-consumption, and ensure uninterrupted power during blackouts, this Lifepo4 Battery serves as a cornerstone of any residential energy storage strategy. Whether used in conjunction with rooftop solar panels or as a standalone emergency power source, it provides peace of mind through consistent, clean, and cost-effective energy solutions.

Users consistently praise its quiet operation, minimal maintenance needs, and robust build quality. Many report significant reductions in electricity bills when paired with solar generation systems, along with improved resilience during storm-related outages or planned load shedding events. Installation by certified professionals is strongly recommended to ensure compliance with local electrical codes and maximum system lifespan.

Common inquiries often focus on compatibility with existing inverters, scalability options, and expected lifespan under daily cycling. This model performs reliably with most hybrid inverters supporting 51.2V DC input and can be expanded in parallel configurations to meet growing energy demands. With a design life exceeding 15 years at room temperature, it represents one of the most future-proof home battery technologies available today.
