Eleven Energy North Sea EL6000 6kW Hybrid Inverter – Single Phase

Eleven Energy North Sea EL6000 6kW Hybrid Inverter – Single Phase is a smart, high‑efficiency 6kW hybrid inverter optimised specifically for Eleven’s sodium‑ion battery chemistry. Using Silicon Carbide (SiC) power electronics, it delivers higher efficiency, reduced losses and a longer service life, making it a reliable workhorse for larger domestic PV and storage systems.

Key Features

• 6kW single-phase hybrid inverter – provides 6,000 W nominal AC output at 230 V for larger domestic loads and higher PV capacities.
• Optimised for sodium-ion batteries – purpose-built to maximise performance and lifetime of Eleven Volta sodium-ion batteries, with matched voltage and control profiles.
• Silicon Carbide technology – SiC-based power stage for higher efficiency, cooler operation and extended lifespan compared with conventional silicon inverters.
• High PV input power – supports up to around 9 kWp of PV input, allowing generous array oversizing and flexible roof layouts.
• High charge / discharge rate – battery charge/discharge current up to 100 A, enabling up to 6 kW of rapid energy transfer between batteries and loads.
• Backup power with fast switchover – integrated EPS (emergency power supply) output with sub‑10 ms on/off‑grid switchover for supported backup circuits.
• Smart tariff compatible – supports intelligent work modes for off‑peak charging, export limiting and smart‑home style energy optimisation.
• Easy commissioning – simple setup and monitoring through the Eleven Energy app, giving fine-grained control over system behaviour.
