Driving 5 kW residential inverters from a single battery module.
FB-L-5.12 · 100 A CONTINUOUS · 5 KW DC

Driving 5 kW residential inverters from a single battery module.

Standard low-voltage batteries require connecting multiple modules in parallel to supply 5 kW. The FB-L-5.12 provides 100 A continuous output from a single unit.

16S series LFP cell string provides 51.2 V nominal (44.8–56.8 V operating range).
Delivers up to 5.12 kW continuous DC power into 48 V hybrid and off-grid inverters.
Internal pre-charge soft-start circuitry prevents inverter capacitor inrush tripping during startup.
Clean domestic aesthetics with scalable multi-module parallel links.
FB-L-5.12 · 100 A CONTINUOUS · 5 KW DC

Clean domestic aesthetics with scalable multi-module parallel links.

Eliminating industrial server-rack aesthetics in residential spaces, the FB-L-5.12 features a sleek, powder-coated casing that mounts cleanly on garage walls.

Supports versatile wall-mount or floor-standing installation with integrated concealed cable channels.
Parallel link up to 16 units on a shared DC bus using the Pylontech LV-Hub-V2.
IP65 rated enclosure certified for unheated basements, technical utility rooms, and sheltered outdoor alcoves (-10 to +50 °C).
