EcoFlow PowerOcean 2 Plus 12kW Three-Phase Hybrid Inverter
- 12kW three-phase hybrid inverter for solar PV, compatible PowerOcean LFP battery storage and 400V three-phase properties.
- Supports up to 16kW of solar PV input across two independent MPPT trackers.
- Provides up to 12kW on-grid output and 12kVA three-phase backup power when installed as part of a correctly designed system.
EcoFlow PowerOcean 2 12kW 3-phase hybrid inverter
The EcoFlow PowerOcean 2 Plus 12kW Three-Phase Hybrid Inverter is designed for compatible homes and light-commercial premises with a 230/400V three-phase electricity supply. It connects solar PV, compatible EcoFlow PowerOcean high-voltage batteries, site loads and the grid to support solar self-consumption, battery storage and managed backup power.
With two MPPT trackers and up to 16kW maximum PV input, the inverter is suitable for solar arrays installed on two roof orientations or arranged as two independently designed strings. It supports up to 12kW battery charging and discharging power, with a stated maximum battery capacity of 45.9kWh.
Key features
- 12,000VA nominal and maximum apparent output power to the utility grid.
- 16,000W maximum PV input, with two MPPT trackers and up to 8,000W per MPPT.
- 12,000W maximum battery charging and discharging power.
- 12,000VA nominal three-phase backup output, with 14,400VA maximum apparent power for one second.
- IP65 protection, natural-convection cooling and integrated electrical protection functions.
Where to use the EcoFlow PowerOcean 2 Plus 12kW inverter
The EcoFlow PowerOcean 2 12kW three-phase hybrid inverter is suitable for larger homes, farmhouses, workshops and compatible light-commercial premises with a three-phase grid connection. It can be specified for high-output solar PV systems, battery storage, solar self-consumption and designed backup-power installations.
It is particularly relevant for sites with higher electrical demand, such as properties with EV charging, heat pumps, large outbuildings, workshop machinery or several substantial electrical loads. The final system should be designed around the site supply, peak demand, PV array configuration, battery capacity and required backup circuits.
This inverter is not a plug-and-play product. A competent installer must confirm PV string voltage and current, three-phase supply arrangement, battery compatibility, metering, protection equipment, backup-load design and G98/G99 grid-connection requirements. UK expert support is available, and Energian can help arrange installation through trusted partners.
