EcoFlow PowerOcean 2 Plus 8kW Three-Phase Hybrid Inverter
- 8kW three-phase hybrid inverter for solar PV, compatible PowerOcean LFP batteries and 400V three-phase properties.
- Supports up to 12kW of solar PV input across two independent MPPT trackers.
- Provides up to 8kW of on-grid output and 8kVA of three-phase backup power when installed as part of a correctly specified system.
EcoFlow PowerOcean 2 8kW three-phase hybrid inverter
The EcoFlow PowerOcean 2 8kW Three-Phase Hybrid Inverter is designed for compatible three-phase homes and light-commercial properties with solar PV and high-voltage battery storage. It manages energy between the solar array, PowerOcean battery, site loads and the electricity grid to support solar self-consumption and battery-led energy management.
The inverter supports up to 12kW of PV input through two MPPT trackers, making it suitable for arrays on two roof orientations or two separate solar strings. It can be paired with EcoFlow PowerOcean LFP battery storage, with a stated maximum battery capacity of 45.9kWh.
Key features
- 8,000VA nominal and maximum three-phase on-grid output power.
- 12,000W maximum PV input, with two MPPT trackers and up to 6,000W per MPPT.
- Up to 8,000W maximum battery charging and discharging power.
- 8,000VA nominal backup output, with 9,600VA maximum apparent power for one second.
- IP65 protection, natural-convection cooling and integrated electrical protection functions.
Where to use the EcoFlow PowerOcean 2 8kW inverter
The EcoFlow PowerOcean 2 8kW three-phase hybrid inverter is suitable for compatible homes and small commercial premises with a 230/400V, three-phase supply. Typical applications include larger homes, farmhouses, workshops, small businesses and properties with greater electrical demand from EV charging, heat pumps or multiple electrical loads.
It can be specified for new solar-and-battery systems or as part of an upgrade where the existing PV array, supply arrangement and battery design are compatible. The two MPPT inputs are useful where solar modules are installed on different roof aspects, such as east/west or south/east.
This is not a plug-and-play product. A competent installer must confirm the PV string design, three-phase supply arrangement, battery compatibility, smart-meter connection, backup-load requirements, protective equipment and G98/G99 grid-connection process. UK expert support is available, and Energian can help arrange installation through trusted partners.
