Inverter – EcoFlow – EF_HD-P3-8K-S1 – hybrid – HV
Product details
PowerOcean
PowerOcean is a modular solution with an LFP battery and a hybrid inverter for residential three-phase photovoltaic systems. It allows capacity expansion and use as a backup power supply during power outages. Users have access to the EcoFlow app and web portal.
Key benefits of PowerOcean
- Modular capacity: the battery’s nominal capacity is 5.1–15.3 kWh, depending on the configuration, with the option of later expansion.
- Power matched to the configuration: the battery’s maximum output power is 3.3–9.9 kW, and its input power is 2.5–7.5 kW.
- Backup power: the ability to use the system during power outages.
- Battery protection: LFP cells and an integrated active aerosol fire protection module.
- Battery operating parameters: IP65 protection rating, natural convection cooling and a noise level not exceeding 35 dB.
- User access: EcoFlow app and EcoFlow web portal designed for system users.
Who is this a good choice for?
PowerOcean is designed for households with a three-phase photovoltaic system that want to store energy and use backup power during power outages. The modular design also meets the needs of homeowners planning to start with a smaller battery capacity and expand it later.
