The myenergi libbi Cable Expansion Kit 15kWh (MYEN-LIBBI-EK151) is the pre-cut, pre-terminated interconnect cable set required to connect a 15kWh libbi battery system (3 × 5kWh battery modules, arranged in two stacks) to the libbi hybrid inverter. Every libbi installation requires the cable kit matched to the battery capacity — this kit is sized precisely for a three-module, 15kWh system.

⚠️ Essential Component — Choose the Correct Kit for Your Battery Size
Each libbi cable kit is engineered for a specific battery configuration. This kit (LIBBI-EK151) is for a 15kWh system using 3 battery modules arranged in two stacks (2+1). For 15kWh and 20kWh systems, the libbi battery arrangement splits into two side-by-side stacks, and 2 × LIBBI-FS01 floor stands are recommended. The LIBBI-TP1 top cover is also available for a neat finish on these larger systems.

Frequently Asked Questions
Is the cable kit included when buying a complete 15kWh libbi bundle?
Yes — complete 15kWh libbi bundles include the LIBBI-EK151 cable kit. This product is listed separately for installers purchasing components individually or replacing a cable kit.
Why are two floor stands recommended for the 15kWh system?
A 15kWh libbi system uses three battery modules arranged in two separate side-by-side stacks (one stack of two batteries, one stack of one battery). Each stack sits on its own floor stand, so two LIBBI-FS01 units are recommended to ensure both stacks are level. The floor stand is optional if the installation surface is confirmed to be perfectly level.
Do I need the LIBBI-TP1 top cover for a 15kWh system?
The LIBBI-TP1 top cover is optional but recommended for 15kWh and 20kWh systems. On these larger installations, the top of the shorter battery stack (the single-module stack in a 15kWh system) has exposed handles that the top cover neatly conceals, giving the installation a cleaner, more professional appearance.
Are the cables pre-cut and pre-terminated?
Yes — all 12 cables in the kit are factory pre-cut to the exact lengths specified in the libbi installation manual for a 15kWh three-module system, and pre-terminated with the correct connectors. The longer cable runs (including the 1700mm and 1800mm cables) bridge the distance between the two battery stacks.
Can I later expand a 15kWh system to 20kWh?
Yes — libbi is modular by design and can be expanded up to 20kWh (4 modules) with a single inverter. When adding the fourth battery module, this EK151 cable kit would be replaced with the LIBBI-EK201 (20kWh) cable kit, which includes the additional cables for the fourth module. An additional LIBBI-B05H battery module would also be required.
