This version comes with a stack control panel and base.
The Fogstar Energy 16.1kWh Battery Module is a high-capacity LiFePO₄ energy storage solution designed for residential, commercial and light industrial applications.
Each battery module forms part of the Fogstar Energy Modular Battery Stack system, allowing installations to be configured from a single 16.1kWh module up to large-scale multi-stack energy storage systems exceeding 1.23MWh.
Designed for flexibility, easier handling and future expansion, each 16.1kWh module integrates seamlessly into the wider Fogstar Energy ecosystem. When combined with the stack control unit and base plate, modules operate as one unified battery system with advanced monitoring, protection and communication capabilities.
With IP-rated construction, integrated heating and built-in fire suppression compatibility, the system is engineered for safe, reliable operation in demanding environments.

What's included?
The system is supplied with pre-terminated 95 mm² battery power cables for straightforward installation. These enable direct connection between the battery system and inverter, or via an external busbar where required.
Battery to battery cables are terminated with Amphenol connectors for secure, low-resistance connections.
A 1.5 m communication cable IS also supplied to enable system control and data integration.
The supplied power cables are compatible with most inverter systems. In some installations, battery cables may be routed to a busbar, with manufacturer-supplied inverter leads used for the final connection. For correct installation, all negative connections must be made before connecting the positive.
