  • Highly safe energy storage system
  • Light weight modular rack design
  • Horizontal or vertical mounting
  • Optional pre-installed busbars and cabling
  • Plug and play
  • DNV type approval optional
  • Safe LiFePO4/LFP chemistry with prismatic cells

Safe modular accuracy system

Perfect for power installations with an inverter up to 7 kW, for example in medium-sized yachts, mobile workshops, and RVs. Strong housing with aesthetically sleek looks. A very safe way of energy storage. The cabinet is screwed into the technical space, therefore no chance of sliding let alone falling over. No additional ventilation or cooling required. Advanced BMS system with precise battery monitoring through Whisper Interface Box WIB (not included). This ensures the modules charge and discharge equally.

Safety

  • Safest and most reliable energy storage on the market
  • Extinguishable with all common extinguishing methods including water
  • Integrated safety measures
  • No risk of thermal runaway
  • Passive safety: even without electronics, the battery modules are safe

Lithium Battery with LiFePO4 Technology

This battery rack is equipped with 8 modules that deliver a capacity of 420 Ah and a total energy storage of 11.1 kWh at a voltage of 24 VDC. Guaranteed highest quality thanks to LiFePO4 chemistry with primary cells. LiFePO4 stands for lithium iron phosphate and is also known by the abbreviation LFP. This is the safest lithium technology ensuring a longer lifespan, improved discharge, and charging efficiency. This makes the battery perfectly suitable for maritime applications. Additionally, lithium is completely maintenance-free and lighter in weight compared to other technologies. Want to know more? Everything about this lithium technology and applications can be found on the lithium battery information pages: part 1 and part 2.

Outstanding Scalable Energy Solution

Our Lithium Power Plus modular battery racks are excellent scalable energy solutions ensuring high-performance output. This specific construction of the battery modules within the enclosure extends lifespan, reliability, and ensures stable energy delivery. The design process includes carefully balancing the charging and discharging of each module, which poses a challenge with individual modules and their wiring.

Custom Design

Besides the standard models in horizontal and vertical configurations, much more is possible. We are happy to design your enclosure custom, with or without integrated DC distribution and one or more Whisper Interface Box battery management systems.
