Eleven Energy North Sea EL5000 5kW Hybrid Inverter – Single Phase

Eleven Energy North Sea EL5000 5kW Hybrid Inverter – Single Phase is a smart, high‑efficiency 5kW hybrid inverter optimised for Eleven’s sodium‑ion Volta battery system. It combines a powerful single‑phase PV inverter, high‑rate battery charger and intelligent energy manager in one compact IP65 unit, ideal for larger domestic installations.

Key Features

• 5kW single-phase hybrid inverter – delivers 5 kW nominal AC output power at 230 V for typical UK households with higher loads.
• Optimised for sodium-ion batteries – purpose‑built to work with Eleven Volta sodium‑ion packs, matching voltage range and charge/discharge characteristics.
• High solar input – supports up to 8 kWp of PV input with dual MPPTs, enabling oversized arrays and flexible roof layouts.
• Fast battery charging – battery charge/discharge rate up to 100 A (5 kW), ensuring rapid storage of surplus PV and fast response to load changes.
• Backup power capability – dedicated EPS (emergency power supply) port for backup circuits during grid outages (when configured and within rating).
• Smart tariff compatible – supports time‑of‑use strategies, allowing charging from cheap off‑peak tariffs and discharging at peak times.
• High efficiency – PV conversion efficiency up to 98%, with battery charge/discharge efficiency around 95%, minimising system losses.
