AkuBox LiFePO4 314 Ah 51.2 V CAN 2.0/RS485 Stackable

The high-capacity AkuBox 314 Ah / 51.2 V battery combines a set of high-performance prismatic LiFePO4 cells with advanced Jikong (JK) BMS technology. This combination ensures precise active balancing and comprehensive cell protection, making the AkuBox the optimal solution for modern photovoltaic systems (PV).

Thanks to its high reliability and modular design, the storage capacity can be scaled as needed—up to 15 units can be connected in parallel, meeting the needs of both single-family homes and larger commercial buildings.

Optional Warranty

With this product, you can choose the warranty period yourself based on your preferences:

  • The standard version comes with a 2-year warranty. This is the most affordable option for those seeking high-quality technology at the lowest possible price.
  • You canextend the warranty to 5 years by checking the box in the “Extra Options” section. This option provides long-term peace of mind, ensuring that your investment in battery storage is secure.

Key Features: 

  • Integrated Smart BMS with active balancing: Unlike conventional passive systems, it actively balances the voltage between cells, thereby maximizing usable energy and significantly extending the battery’s lifespan.
  • Wide System Compatibility: The AkuBox features CAN 2.0 and RS485 communication ports, ensuring seamless integration with leading solar inverters (Must, Victron Energy, Growatt, GoodWe, DEYE, and others).
  • Maximum safety and durability: The certified cells are protected by a robust cold-rolled steel (SPPC) chassis with an IP40 rating. An integrated DC circuit breaker is mounted on the front panel for overcurrent protection.
  • Battery Monitoring and Management: The front panel features an LCD display for real-time diagnostics and configuration of communication protocols for interfacing with inverters.
