One coordinated system, built around your home

OCEAN 2 Plus combines a high-output single-phase hybrid inverter, modular 5.02kWh LiFePO4 battery packs, integrated backup architecture and EcoFlow energy management in one clean platform. Instead of piecing together separate boxes, meters and backup components, your installer can design the system as a coordinated whole.

Indicative installed package from $9,999 Brisbane/Gold Coast/Sunshine Coast only

This guide is based on a 20.08kWh battery stack, compatible OCEAN 2 Plus inverter and a standard installation allowance. The inverter model, backup circuits, switchboard work, cable runs, metering and final installed price must be confirmed in a written site-specific quote.

Why homeowners will love OCEAN 2 Plus

Capture more roof space

Three independent MPPTs make it easier to work with multiple roof orientations or partial shading. Each MPPT supports up to 8kW input, with up to 24kW total PV input on the 12kW model.

Keep more of your solar

Store excess daytime generation and use it through the evening, overnight or during expensive tariff periods instead of exporting it for a lower rate.

Backup without the box maze

Integrated backup architecture simplifies the design. Your installer still needs to confirm which circuits and total loads can be supported by the selected inverter and battery configuration.

Expand as life changes

Start with the storage that suits today and expand within the approved system limits as your household, EV charging, heat-pump or backup needs grow.

What can change the installed price?

The guide price assumes a straightforward installation. A final quote may change for switchboard upgrades, long cable runs, metering or network requirements, difficult access, additional backup circuits, bollards or smoke-alarm requirements, travel, trenching or remedial electrical work.

We prefer to price the real job properly: no vague promises, no undersized backup expectations and no surprise system design after you have committed.

Is this the right system for your home?

Send us your suburb, a recent electricity bill, your existing solar-system size, whether the property is single-phase, and the appliances you want supported in a blackout. We can then recommend the right inverter, battery capacity and backup design.
