The myenergi libbi Hybrid 3.68kW (MYEN-LIBBI-310SH) is a complete all-in-one hybrid inverter and 10kWh battery storage bundle — including the 3.68kW libbi hybrid inverter, 2 × 5kWh battery modules, LIBBI-C110W controller, and 10kWh cable kit. Designed for UK homes with solar PV systems generating 1–4kWp, it operates as an AC-coupled, DC-coupled, or hybrid coupled battery system, with EPS blackout backup capability and deep integration with the wider myenergi ecosystem.
3.68kW Hybrid Inverter
10kWh Storage Included
AC & DC Coupled
G98/G99 Compliant
EPS Blackout Backup
IP65 Rated
10-Year Battery Warranty
⚠️ Professional Installation Required
All myenergi libbi systems must be installed and commissioned by a trained and approved installer. Installation by an uncertified person will void the manufacturer's warranty. The system must be registered via the myenergi Installer Portal and comply with G98/G99 grid connection requirements.

Frequently Asked Questions
What is the difference between the 3.68kW and 5kW libbi inverter options?
The 3.68kW inverter (LIBBI-HS3680) is suited to PV systems generating 1–4kWp and is the most common choice for typical UK domestic installations with standard solar arrays. The 5kW inverter (LIBBI-HS5000) is suited to larger PV systems generating up to 5kWp and provides higher AC output power. Both inverters support the same battery modules (1–4 × 5kWh modules) and the same ecosystem integration.
Can libbi be used without solar panels?
Yes — libbi can be installed in homes with no solar generation as a grid-optimisation battery. In this configuration, it charges from the grid overnight on cheap time-of-use tariffs (e.g. Octopus Go, Agile, Economy 7) and discharges during peak-rate periods, reducing electricity costs. This makes it particularly cost-effective with a smart export or dynamic tariff.
How does the EPS blackout backup work?
When the grid fails, libbi's Emergency Power Supply (EPS) mode automatically disconnects from the grid and uses stored battery energy to power a dedicated circuit (typically a single socket or lighting circuit). The switchover is near-instantaneous. Note that EPS backup must be specifically wired in during installation — it is not automatically available on all installed loads, only those connected to the designated backup output.
How does libbi integrate with a zappi EV charger or eddi solar diverter?
libbi communicates with other myenergi devices via the LIBBI-C110W controller and the myenergi ecosystem (868/915MHz radio + app). When libbi, zappi, and eddi are installed together, the system makes intelligent decisions about whether to store surplus solar in the battery, use it to charge the EV via zappi, or heat water via eddi — based on your priorities and available energy. This whole-home energy management can significantly improve solar self-consumption.
Can I expand this 10kWh system in the future?
Yes — the 3.68kW libbi supports up to 4 × 5kWh battery modules (20kWh total). This bundle includes 2 modules (10kWh), so you can add up to 2 more modules to reach 20kWh. When expanding, you will need additional LIBBI-B05H battery modules and the corresponding larger cable kit (LIBBI-EK151 for 15kWh, or LIBBI-EK201 for 20kWh) to replace the included EK101 kit.
