The myenergi libbi Cable Expansion Kit 20kWh (MYEN-LIBBI-EK201) is the pre-cut, pre-terminated interconnect cable set required to connect a 20kWh libbi battery system — the maximum configuration of 4 × 5kWh battery modules arranged in two stacks of two — to the libbi hybrid inverter. This is the largest cable kit in the libbi range and represents the maximum single-inverter storage capacity of 20kWh.
Required for 20kWh libbi Installation
Pre-Cut & Pre-Terminated
3-Year Warranty
Maximum Capacity Configuration
For 4 × Battery Modules
⚠️ Essential Component — Maximum 20kWh libbi Configuration
This is the cable kit for the maximum libbi storage configuration: 4 battery modules in two stacks of two, providing 20kWh total capacity. For this configuration, 2 × LIBBI-FS01 floor stands are recommended (one per stack), and the LIBBI-TP1 top cover is available to give the installation a neat, professional finish.

Frequently Asked Questions
Can I store more than 20kWh with a single libbi inverter?
No — 20kWh (4 × 5kWh battery modules) is the maximum storage capacity for a single libbi inverter. To store more than 20kWh, a second parallel libbi system would be required (with its own inverter and battery modules). The EK201 is therefore the largest cable kit in the libbi range.
Is the cable kit included in a complete 20kWh libbi bundle?
Yes — complete 20kWh libbi bundles include the LIBBI-EK201 cable kit. This product is listed separately for installers purchasing components individually or replacing a cable kit on an existing installation.
Why does the 20kWh kit include some cables in pairs (×2)?
The 20kWh system uses two stacks of two batteries each, arranged side by side. The duplicate cable lengths (e.g. two × 485mm negative cables) are used to make the connections within each battery stack, while the longer cables (up to 3300mm) bridge between the stacks and from the stacks to the inverter. All cables are factory-matched to the exact libbi installation topology.
Do I need two floor stands for a 20kWh system?
Two floor stand units (2 × LIBBI-FS01) are recommended for a 20kWh system — one per stack. The floor stand is optional if the installation surface is verified as perfectly level, but it is strongly recommended for a professional installation and to ensure system stability.
Is the LIBBI-TP1 top cover compatible with the 20kWh system?
Yes — the LIBBI-TP1 top cover is specifically designed for 15kWh and 20kWh systems, where the top handles of the battery units are exposed. For a 20kWh system (two stacks of two), one LIBBI-TP1 cover is used to conceal the top handles and give a neat, uniform appearance to the completed installation.
