Sunpok 51.2V 300Ah: High-Density Storage for the Modern Energy Landscape
As residential energy consumption patterns evolve, the need for robust and dependable storage solutions becomes critical. The Sunpok 51.2V 300Ah Floor-Standing Lithium Battery is engineered to serve as the primary energy reservoir in advanced home power systems. By consolidating 15.36kWh of nominal capacity into a single vertical enclosure, this unit provides a streamlined alternative to complex multi-battery arrays, offering a practical solution for homeowners seeking to maximize their solar utilization and maintain power continuity.
Reliable LiFePO4 Performance
This battery utilizes Lithium Iron Phosphate (LiFePO4) chemistry, selected for its inherent stability and suitability for stationary applications. The 51.2V configuration is purpose-built to integrate seamlessly with industry-standard 48V hybrid and off-grid inverters. With a 300Ah rating, the battery supports sustained power delivery for high-demand appliances, including air conditioning units, water heaters, and essential lighting circuits. This ensures that homes can remain operational through extended evening hours or during grid outages without the volatility associated with less stable chemistries.
Advanced System Monitoring
The internal Battery Management System (BMS) acts as the operational brain of the unit, continuously monitoring cell voltages and temperatures to maintain optimal performance. It facilitates active cell balancing, which is crucial for preserving battery health over long periods of use. Communication is handled via standard CAN and RS485 protocols, allowing the battery to interface directly with compatible inverters. This connectivity enables precise state-of-charge tracking and automated charge-discharge cycling, ensuring the system responds intelligently to real-time energy demands.
Designed for Protected Indoor Use
The floor-standing cabinet design offers a compact footprint while providing structural stability. Rated for protected indoor environments, the unit is suitable for installation in utility rooms, garages, or equipment closets where it is shielded from direct exposure to the elements. The IP21-rated enclosure protects against solid particles and condensation, safeguarding internal components. The front panel provides clear operational status, while the terminal layout is optimized for efficient wiring by qualified electrical professionals.
A Foundation for Custom Installations
Sunpok designs this product as a core component for tailored energy solutions. It is intended for integration by licensed installers who can ensure compliance with local electrical codes and proper synchronization with existing PV systems. For distributors and system integrators, the 51.2V 300Ah model represents a high-capacity, single-unit option that simplifies project logistics and reduces the complexity of on-site assembly. It is built to deliver consistent, long-term performance as part of a comprehensive home energy strategy.
