LFP Home Battery Overview
Modular Home Battery System

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 Diagram

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.

Frequently Asked Questions
What is the modular capacity range of the LFP home battery?

The battery is modular in 2.88 kWh increments, allowing a capacity range of 8.64kWh up to 28.8kWh per stack. This modularity ensures easy maintenance and simplifies future capacity upgrades.

Why is Lithium Iron Phosphate (LFP) preferred for home storage?

LFP (LiFePO4) is the safest chemistry among mainstream lithium batteries. It delivers high round-trip efficiency, superior energy density, support for fast charge/discharge currents, and reliable performance even in rugged deficit operating conditions.

What voltage options are available in this battery series?

Depending on the configuration, the nominal voltage ranges from 172.8V (for 3 modules) up to 576V (for 10 modules), with operating voltage windows stretching between 135V and 657V.

What safety standards do these batteries comply with?

Our battery modules comply with major international quality and safety certifications including CE, UN38.3, IEC62619, IEC63056, and IEC62477.

Can the capacity be expanded in the future?

Yes, the stack-mounted modular design allows you to add additional 2.88 kWh battery modules to scale up your storage capacity up to 30kWh per stack as your power backup requirements grow.
