The Rack Battery Cabinet offers an affordable, customized energy solution. By including only essential components such as batteries and PCS, the system retains its critical energy storage functionality while reducing overall costs.
PKNERGY handles the complete construction process, from battery assembly to PCS integration. All internal wiring is pre-installed at the factory, requiring only simple on-site connections to set up an off-grid system, eliminating complex installation procedures.
From battery capacity to cabinet type, and even cell brands, the Rack Battery Cabinet is fully customizable. Customers can tailor the system to fit their specific site requirements, ensuring optimal configuration.
The cabinet uses LiFePO4 cells, renowned for their outstanding safety performance. They are resistant to fire and contain no harmful substances, unlike lead-acid batteries, which require regular maintenance.
With three times the energy density of lead-acid batteries, the PKNERGY Rack Battery Cabinet conserves space. Its robust rack design allows flexible placement without requiring wall support.
A battery cabinet is a structured enclosure designed to house and organize multiple batteries, typically used in energy storage systems for commercial, industrial, or residential applications.
A typical household uses 20~30KWH of batteries a day. A Battery Cabinet assembled with 4 5kwh rack-mounted batteries can maintain a household’s power for a whole day, but it depends on your load requirements. Calculating the actual power consumption will help you choose how many battery units the Battery Cabinet needs and effectively control costs.
