KeepKnow 48V(51.2V)100Ah Server Rack LiFePO4 Battery stores approximately 5.12 kWh of usable energy, making it ideal for home backup, solar energy storage, RV systems, and off-grid applications.

Depending on power consumption, it can support essential appliances such as refrigerators, lighting, Wi-Fi routers, TVs, and other household electronics for several hours or longer.

Backup time depends on the total power consumption of connected devices.

For example, under a typical 5,120Wh (1P) configuration, low-power loads such as lighting and network equipment (around 200W total load) can operate for approximately 25 hours. In contrast, high-power appliances such as air conditioners or electric heaters (around 2,000W load) will reduce runtime to approximately 2.5 hours.

For extended backup duration, multiple batteries can be connected in parallel.

Server rack batteries are designed for modular installation, efficient space utilization, and easy system expansion.

Their rack-mounted design simplifies installation and maintenance, making them ideal for residential solar storage, backup power systems, and scalable energy projects.
