Power Stored with Purpose: The SUNPOK 51.2V 300Ah Floor-Standing Home Lithium Battery
Energy independence begins with a decision to store power on your own terms. The SUNPOK 51.2V 300Ah Floor-Standing Lithium-Ion Battery is built for homeowners who want a substantial, reliable energy reserve at the heart of their solar or hybrid power setup. Engineered as a single vertical cabinet, it brings meaningful storage capacity into the home without complicating the living space.
A Vertical Cabinet Designed for the Home
The floor-standing form factor is conceived for practical placement in utility rooms, garages, or other protected indoor areas. Its vertical structure prioritizes stability and efficient use of floor space, allowing the battery to serve as a quiet, integrated component of the home energy system rather than an intrusive piece of equipment. The enclosure carries an IP21 rating, offering basic protection against dust and vertically dripping water, making it suitable for standard indoor environments.
LiFePO4 Chemistry for Long-Term Confidence
At the core of the unit is Lithium Iron Phosphate (LiFePO4) chemistry, chosen for its thermal stability, safety characteristics, and long service life. Combined with a built-in Battery Management System, the battery actively monitors voltage, current, and temperature while balancing cells during charge cycles. This protects the system and preserves capacity over years of daily use. Communication is handled through standard CAN and RS485 protocols, allowing the battery to exchange real-time data with compatible inverters and enabling intelligent oversight of the energy flow.
Substantial Capacity for Real Household Demands
With a nominal voltage of 51.2V and a 300Ah rating, the battery delivers a generous energy reserve capable of supporting essential household loads during grid outages or maximizing solar self-consumption from day into night. It is designed to work alongside industry-standard 48V hybrid and off-grid inverters, giving installers and system designers the flexibility to build a customized energy storage solution around it.
Engineered by a Dedicated Manufacturer
SUNPOK Energy develops and manufactures advanced lithium battery systems for residential storage applications. The 51.2V 300Ah floor-standing model reflects that manufacturing focus: a high-density, single-cabinet alternative that reduces system complexity and minimizes potential connection points. Every unit is factory-tested for performance and safety before shipment, ensuring consistent quality from production line to home.
A Foundation for Energy Resilience
The SUNPOK 51.2V 300Ah battery is a core component for professional integration. It is intended to be connected to a compatible external inverter by qualified electrical professionals, forming the storage foundation of a customized home energy setup. For distributors, integrators, and homeowners planning a robust residential power system, it offers a reliable, high-capacity building block.
