PRODUCT DETAILS
Complete product details — specifications, images, FAQ, and downloadable resources for this VoltCrave power solution
The LS-5K25B is a 25KW stacked energy storage system designed around a modular LiFePO4 battery architecture. It combines energy storage, solar integration and power management in one compact platform.
Five 5.12KWh battery modules provide a total energy capacity of 25.6KWh. The complete battery configuration delivers 51.2V and 500Ah.
The system uses five vertically stacked 51.2V 100Ah LiFePO4 battery modules. Its modular structure provides substantial energy capacity while maintaining a compact floor footprint.
The PV MPPT operating voltage range is 120–450VDC for integration with compatible photovoltaic systems. Solar, battery and mains power priorities can be selected according to application requirements.
The battery supports up to 100A charging and 100A continuous discharging, with a continuous charging current of 40A. Charge and discharge cut-off voltages are 58.4V and 40V.
The LiFePO4 battery is rated for more than 6000 cycles with 80% DOD. This supports long-term energy storage applications requiring frequent battery cycling.
A 10ms transfer time supports rapid power-source switching. RS232, RS485, CAN and WiFi interfaces provide flexible communication and system integration.
Active cooling supports operation from -20°C to 60°C with specified noise below 50dB. VoltCrave Power can customize system specifications and configurations according to customer requirements.
