Product overview
Core is the open-rack member of Focal. It keeps the battery packs visible inside a 19-inch architecture and brings low- and high-voltage project paths into one maintainable product family.
Focal takes its name from the point where an orbit is organised: a C&I series for bringing storage, conversion and control together.

Product architecture
Define the system boundary first
The open format makes module arrangement, cabling and service access part of the visible design. Conversion, enclosure protection and site controls are coordinated around the rack.
One family, two voltage paths
Low- and high-voltage configurations remain under one Focal Core product identity.
Service-led structure
The 19-inch rack format puts module access and maintainability at the centre of the architecture.

Configuration shortlist
A focused product range
Each product stays focused on one or two published configurations. Installation, voltage, enclosure, interface and power-conversion choices stay visible without turning every option into another SKU.

- Wi-Fi option
- Bluetooth
- Low-voltage inverter pairing
-
- 14 kW three-phase
- 20 kW three-phase
The matching three-phase inverter platform uses a 40–60 V battery input, IP65 enclosure and touch LCD. This option applies to the low-voltage rack only and requires BMS, current and parallel-pack checks.

Application fit
Start with the project
Application fit shows where to begin the engineering conversation. Final compatibility and performance are confirmed during project review.
Integrator-built systems
Consider Core when the battery rack is one visible layer inside a wider engineered storage system.
Equipment-room deployment
Use the open format where the room or external enclosure supplies the required environmental boundary.
Service-oriented storage
Select the rack architecture where module visibility and planned access are central to the maintenance concept.
