The myenergi libbi Controller (LIBBI-C110W) is the essential BESS (Battery Energy Storage System) controller required for every libbi home battery installation. It connects the libbi hybrid inverter and battery modules to the myenergi app ecosystem, handles system communication via RS485, and provides the local graphical interface for on-site monitoring and configuration. Without the controller, the libbi inverter and batteries cannot be commissioned or operated.

⚠️ Essential Component — Not Optional
The libbi Controller (LIBBI-C110W) is a mandatory component of every libbi home battery system. It cannot be omitted. One controller is required per libbi installation regardless of the number of battery modules. If you are purchasing a libbi system, this controller must be included alongside the inverter, battery modules, and cable kit.
What Does the Controller Do?
The libbi controller is the "brain" that connects all elements of the libbi system together. It communicates with the inverter and battery modules via a 5-metre RS485 cable, communicates with the myenergi app via WiFi, and connects to any other myenergi devices (eddi, zappi, harvi) via the myenergi radio network. It also provides the local LCD display and four-button interface for on-site status monitoring and configuration.
Key Features
RS485 System Communication
Connects to the libbi inverter and battery modules via the supplied 5-metre RS485 cable, providing reliable wired communication within the system cabinet.
WiFi Connectivity
Built-in WiFi connects the libbi system to the myenergi app, enabling remote monitoring, configuration, firmware updates, and tariff optimisation from anywhere in the world.
Radio Integration
Myenergi radio antenna communicates with other myenergi devices — eddi, zappi, harvi — enabling coordinated whole-home energy management without additional wiring.
Grid CT Monitoring
Includes a CT clamp with 5m cable for monitoring grid import and export — essential for the libbi system to make intelligent charging and discharging decisions.
Graphical LCD Display
Local display with LED backlight and four tactile navigation buttons for on-site status monitoring and configuration — no need for a phone or app for basic operation.
Indoor Mounting
Compact unit designed for indoor wall mounting near the libbi system, with a simple bracket fixing arrangement.

Frequently Asked Questions
Is the controller included in libbi bundle kits?
Yes — when purchasing a complete libbi hybrid bundle (e.g., the 5kW/5kWh or 5kW/10kWh kit), the controller is included as part of the bundle. This product is listed separately for cases where components are being purchased individually to build a custom configuration.
Where should the controller be mounted?
The controller is designed to be mounted indoors on a wall, typically in the same room as the libbi inverter and battery modules. The RS485 cable (5m) must reach from the controller to the inverter. It should be installed in a location with WiFi coverage for app connectivity.
Does the controller come with a CT clamp?
Yes — the controller is supplied with one CT clamp and a 5m cable. This CT clamp is the main grid monitoring sensor for the libbi system and is fitted at the meter board to measure grid import and export.
Can one controller manage multiple libbi battery modules?
Yes — one controller manages the entire libbi system regardless of the number of battery modules (up to four). The RS485 communication bus connects all modules and the inverter through a single controller.
