Description

SunGoldPower 4X 48V 100Ah Server Rack LiFePO4 Lithium Battery SG48100P

The SunGoldPower 4× 48V 100Ah Server Rack LiFePO4 Lithium Battery SG48100P is a high-capacity, modular energy storage solution engineered for residential, commercial, and industrial use. This pack combines four robust 48 V 100 Ah LiFePO₄ battery modules into a scalable rack-mountable system that delivers reliable and efficient backup power, solar energy storage, or off-grid support for demanding applications.

Designed with advanced lithium iron phosphate chemistry and an integrated smart Battery Management System (BMS), this battery pack provides superior safety, efficiency, and cycle life. The BMS continuously safeguards against overcharge, over-discharge, short circuit, and temperature extremes, while smart communication support (RS232/RS485/CAN) ensures seamless integration with most inverters and energy management systems.

With a nominal 51.2 V and a total energy capacity of around 20.48 kWh (4×5.12 kWh), this battery pack stands out for its ability to support extended energy demands and heavy loads in off-grid homes, emergency backup systems, data center UPS setups, and hybrid solar installations. Its stackable design lets you expand further — up to 32 units in parallel — for even greater storage potential as your energy needs grow.

Built for long-term performance with a cycle life exceeding 7,000 cycles and a calendar life of over 15 years, the SunGoldPower SG48100P pack delivers dependable, maintenance-free power for years to come. Whether you’re adding resilience to your home, supporting a commercial system, or powering critical infrastructure, this battery pack is a professional-grade choice
