Why OCEAN 2

A Complete Storage System, Not Just a Battery

5 kWh or 8 kWh modules

We size storage around your usage. Any future expansion depends on the model, compatibility and installation requirements.

Backup power

Backup is included only where expressly agreed in your order, with the supported circuits and limits confirmed.

Safe LFP cells

Lithium iron phosphate chemistry for long life and a strong safety profile.

Live app monitoring

Watch generation, storage and usage in real time from your phone.

Peace of mind · Backup power

Keep the Lights on When the Grid Drops

A battery does not automatically mean your home has backup power. If your order includes backup, we explain which circuits it supports and the agreed operating limits. Available power and duration depend on the equipment, battery charge and connected loads.

Frequently Asked Questions

What is the EcoFlow OCEAN 2?

It is EcoFlow’s current home battery range, using 5 kWh or 8 kWh modules. We specify a compatible inverter and storage capacity around your usage, with monitoring through the EcoFlow app. Your quotation confirms the equipment and any backup features.

Can I expand the OCEAN 2 later?

Expansion may be possible, subject to the model, compatibility, available space and installation requirements. Ask us to check your system before choosing additional modules.

Does the OCEAN 2 use safe battery chemistry?

Yes. It uses LFP (lithium iron phosphate) cells, which are known for their long cycle life and strong safety profile compared with some other lithium chemistries.

Does it provide backup power?

Only where backup is expressly included in your order. We confirm the supported circuits, power limits and operating conditions for the agreed equipment. A standard battery installation does not automatically provide backup.
