Battery storage

EcoFlow today, sodium-ion coming soon

A battery stores the solar you don’t use during the day so you can use it in the evening. It can also charge from cheaper overnight electricity, with or without panels.^S6b^S12

Typical systems we fit

Every system is designed at survey, but most of ours look like one of these.

Most homes

4.4 kW home system

10 LONGi 440 W panels with an EcoFlow OCEAN 2 Single-Phase 5 kVA inverter and a 5 or 10 kWh battery.^S60^S2

Larger homes

6 to 7 kW home system

14 to 16 LONGi panels with the new OCEAN 2 Plus Single-Phase and 10 to 16 kWh of battery, room to add more later.^S60^S3

Three-phase homes and farms

9 to 10 kW three-phase system

20 to 22 LONGi panels with an OCEAN 2 Three-Phase 10 kW inverter and 15 to 20 kWh of battery.^S60^S5

Businesses and farm sheds

Up to 40 kW commercial system

Shed or factory roofs with EcoFlow PowerOcean Plus at 29.9 kW and storage sized to your daytime load, up to 180 kWh.^S4

Lithium iron phosphate, by EcoFlow

Whole-home backup with room to grow

EcoFlow PowerOcean pairs a hybrid inverter with stackable lithium iron phosphate (LFP) batteries, the chemistry most home batteries use. Here is why we offer it.^S1^S2

Whole-home backup

The OCEAN 2 range can keep your whole home running in a power cut, with conditions we check at survey.^S2

The most storage on one inverter

Batteries come in 5 or 8 kWh modules: up to 48 kWh on one OCEAN 2 inverter, or 96 kWh on the OCEAN 2 Plus and Three-Phase, for larger homes and heavy evening use.^S2^S3^S5

Built for outdoors

IP66 rated, so it can go on an outside wall or under a carport as well as in a garage.^S2

15-year warranties

The inverter and the 5 kWh battery carry 15-year warranties. The 8 kWh battery carries 10 years.^S2^S6

Adds to the solar you have

It can be added to an existing solar system, so you do not need new panels to get a battery.^S2

Scales to three-phase

PowerOcean Plus runs at 29.9 kW with up to 180 kWh of storage, for larger homes, farms and businesses.^S4

Sodium-ion, by Eleven Energy

Coming soon

A battery built from salt, not lithium

Most home batteries fitted in Northern Ireland are lithium. Eleven Energy’s batteries use sodium-ion, a different chemistry designed in Cambridge for UK homes. Here is why we plan to offer it once it is certified in Northern Ireland.^S10

Made from abundant sodium

Sodium comes from seawater and is plentiful. There is no lithium in the cell, which avoids the mining concerns around lithium and rare minerals.^S10^S12

Works in a cold garage or shed

Rated to charge down to minus 20°C and discharge down to minus 30°C, so it suits garages, outbuildings and farm sheds through a Northern Ireland winter.^S11

Thermally stable

Eleven describes the chemistry as having excellent thermal stability, one reason it is described as a safer option for storage in and around the home.^S12

8,000 cycles, 10 years

Each battery carries a 10-year warranty and an 8,000-cycle guarantee. That is daily charging and discharging for well over the warranty period.^S11^S16

Grows with you

Stackable 4.5 kWh Galvani modules, IP65 rated for indoors or outdoors. Add modules later and the battery management balances old and new.^S11^S12

Your data stays in the UK

The Eleven app runs on iOS, Android and the web, works locally over Bluetooth, and hosts its data in the UK.^S12

Good to know: Eleven backs up selected circuits in a power cut rather than the whole home, and needs an Eleven inverter. If whole-home backup matters most, EcoFlow OCEAN 2 may suit you better, and we’ll say so at survey.^S12

Which one?

A quick way to choose

Choose EcoFlow if

whole-home backup matters most^S2
you want the most storage on one inverter^S2
it’s a large three-phase site^S4

Coming soon

Eleven may suit you if

the battery will sit in a cold garage or shed^S11
you’d rather avoid lithium^S10
backing up chosen circuits is enough^S12
