Product Description

The LFP 9kWh/HV home battery is modular in 2.88 kWh increments, providing a capacity range of 8.64kWh-28.8kWh per stack. This also allows for easy servicing and future expansion. With continuous output at up to 14.4kW, true full-home backup is here.
Product Introduction
Product Introduction Showcase

The lithium iron phosphate battery (LiFePO4 or LFP) is the safest of the mainstream lithium battery types. A single LFP cell has a nominal voltage of 3.2V. A 57.6V LFP battery consists of 18 cells connected in series. LFP is the chemistry of choice for very demanding applications.

Some of its features are:
  • Rugged - It can operate in deficit mode during long periods of time.
  • High round trip efficiency.
  • High energy density - More capacity with less weight and volume.
  • High charge and discharge currents - Fast charges and discharges are possible.
  • Flexible charge voltages.
