Sunpok 51.2V 300Ah: Consolidated Capacity for Residential Solar Integration
The effectiveness of a home solar system often hinges on the quality of its energy storage. The Sunpok 51.2V 300Ah Floor-Standing Lithium Battery is developed to provide a high-capacity, single-unit solution for residential properties. By offering a nominal capacity of 15.36kWh in a unified cabinet, it simplifies the process of scaling storage to meet the demands of modern households, moving away from the constraints of smaller, fragmented battery banks.
Stable LiFePO4 Electrochemistry
Central to this unit is the Lithium Iron Phosphate (LiFePO4) chemistry, recognized for its stability in stationary power applications. The 51.2V platform is designed for direct compatibility with mainstream 48V hybrid and off-grid inverters. The 300Ah current rating ensures the battery can sustain long-duration discharges, making it suitable for powering high-wattage loads such as air compressors, deep well pumps, and comprehensive lighting systems. This capability allows homeowners to extend their solar usage late into the night or maintain critical operations during grid disruptions.
Precision Battery Management
An internal Battery Management System (BMS) oversees the operational health of the pack. It performs essential functions such as cell balancing and voltage monitoring to maintain uniformity across the battery's lifecycle. To facilitate integration into smart energy systems, the unit is equipped with CAN and RS485 communication ports. This allows the battery to transmit vital statistics to the inverter, enabling automated responses to changing load conditions and optimizing the overall efficiency of the energy storage system.
Architected for Indoor Stability
The physical footprint of the Sunpok 51.2V 300Ah is optimized for indoor utility spaces. Its floor-standing design provides a low center of gravity and requires no supplementary racking hardware. Designed for protected indoor environments, the enclosure is suited for placement in utility rooms, garages, or equipment closets. The construction safeguards the internal components against particulate ingress and incidental moisture, ensuring reliable performance in standard residential settings. The terminal access is configured to streamline the connection process for professional installers.
A Component for Professional Deployment
This product is positioned as a core element for custom energy storage solutions. It is intended for installation by qualified electrical professionals who can ensure proper integration with existing electrical infrastructures. For distributors and integrators, this model offers a high-density, single-cabinet alternative that reduces on-site complexity and installation time. It serves as a reliable cornerstone for building resilient and efficient home power systems.
