Sunwoda Atrix SE5 5kWh Low Voltage Battery Module

Sunwoda Atrix SE5 5kWh Low Voltage Battery Module

The Sunwoda Atrix-SE5 is a compact 5 kWh low-voltage lithium iron phosphate (LFP) battery module designed for residential energy storage and flexible modular battery systems.

With 5 kWh usable energy at 100% depth of discharge, high charge and discharge capability and scalability from 5 kWh up to 1.8 MWh, the Atrix-SE5 supports solar self-consumption, time-of-use energy management and backup applications with a compatible inverter.

Designed for indoor rack or built-in cabinet installation, its compact plug-and-play design supports two-person installation, straightforward expansion and reliable operation across a wide temperature range. An integrated low-temperature heating film helps support battery operation in colder conditions.
