EcoFlow PowerOcean, designed around how you use electricity
EcoFlow PowerOcean is a modular home battery system: an inverter that manages your solar panels and battery together, with battery packs you can add over time. Our own team designs and fits EcoFlow PowerOcean across Devon and Cornwall, with new solar panels or alongside panels you already have. We size it around how your household uses electricity, starting with what you need now.

Specifications and warranty
EcoFlow PowerOcean in the maker’s own figures.
EcoFlow PowerOcean is one of the battery systems we design with and fit.
- Single-phase invertersFive models rated from 3 to 6 kilowatts (kW): 3,000, 3,680, 4,600, 5,000 and 6,000 watts.enterprise-service-eu-cdn.ecoflow.com
- Battery packEach PowerOcean LFP (lithium iron phosphate) pack holds 5.1 kilowatt-hours (kWh) nominal and 4.8 kWh usable, at a 95% depth of discharge that can vary in the cold.enterprise-service-eu-cdn.ecoflow.com
- Three-phase6, 8, 10 and 12 kW inverters, starting from one 5 kWh battery; EcoFlow’s page says “expandable up to 45kWh”.energy.ecoflow.com
- PowerOcean PlusThree-phase models of 15, 20, 25 and 29.9 kW, which EcoFlow labels “House / Light Commercial”.energy.ecoflow.com
- Existing solarEcoFlow’s installation guide says PowerOcean works with any single- or three-phase grid-tied solar system; if the existing inverter feeds in less than about 200 W, the battery is not charged.enterprise-service-eu-cdn.ecoflow.com
- Backup switchoverWith the EcoFlow Gateway (Single-Phase), EcoFlow states a “0 ms” load-side switchover for PowerOcean Single-phase, under the test conditions it publishes.energy.ecoflow.com
- Weather ratingThe single-phase inverter and battery are rated IP65 against dust and water and work from minus 20 °C to 50 °C; the inverter reduces output above 40 °C or below 0 °C.enterprise-service-eu-cdn.ecoflow.com
- WarrantyEcoFlow’s UK pages state a 15-year warranty; the policy shown there covers the battery for 15 years or 6,000 charge and discharge cycles, whichever comes first, keeping at least 70% of nominal capacity.energy.ecoflow.com
Modular storage
What EcoFlow PowerOcean is
PowerOcean pairs a hybrid inverter with stackable battery packs, each holding the usable energy shown in the table above, in kilowatt-hours (kWh). EcoFlow’s UK site lists three versions, so the system can match your property’s electricity supply.
It suits a household that would like to start with a modest battery and add to it, because EcoFlow says new packs work alongside existing ones. We begin with how you use electricity: the daytime surplus you could store, and the evenings you would use it. Our page on how battery storage works covers the basics; to compare, Sigenergy’s SigenStor is our premium option.
- PowerOcean Single-phase: for a single-phase supply, in the five inverter sizes listed above.
- PowerOcean Three-phase: for a three-phase supply, in four inverter sizes, and it can begin with a single battery pack.
- PowerOcean Plus: larger three-phase models, which EcoFlow aims at houses and light commercial use.
With your panels
Adding PowerOcean to solar you already have
Starting from scratch, we design your solar panel installation and the PowerOcean battery together, so each part suits the others from the first day.
If you already have panels, you can keep them: the installation guide quoted in the table above covers grid-tied solar photovoltaic (PV) systems on both single- and three-phase supplies. We check your current equipment before recommending anything, and our page on fitting a battery to your existing solar panels covers the process. In the guide’s terms:
- your existing system connects to the PowerOcean inverter’s GRID terminal
- its output supplies your home first, then charges the battery
- if its output falls below the level in the table above, the battery takes no charge
Two warranties
PowerOcean’s warranty, kept separate from ours
EcoFlow’s UK pages give PowerOcean a 15-year warranty. That is EcoFlow’s product warranty, separate from our own 10-year workmanship warranty, which covers our installation work. The policy shown on EcoFlow’s UK site is written for Europe, and the full document is worth reading alongside your quote.
| Term | What the warranty says |
|---|---|
| Inverters | 15 years for the PowerOcean hybrid inverter, single- and three-phase, and for the PowerOcean Plus inverter. |
| Battery | Cover ends at whichever limit in the table above comes first, years or charge cycles, and warrants no less than 70% of nominal capacity when used between minus 20 °C and 50 °C. |
| Gateway | 10 years for the EcoFlow Gateway (Single-Phase). |
| Staying online | More than a year disconnected cuts the warranty to five years. |
| Start date | The earlier of commissioning or nine months after production. |
Fitted and looked after
How our team fits and supports it
Every PowerOcean we fit goes through the four steps below, each handled by our own team. If your system needs approval from National Grid before we can connect it, known as a G99 application, we handle the application for you and keep you updated while we wait for their response.
At handover, we show you how PowerOcean works and how to follow it in the app, and your first year of The Solar Owners Club begins. When you’re ready to start, get in touch with our team.
- Survey: free, with a no-obligation quote, looking at your roof’s orientation, shading and space; a copy of your electricity bill helps.
- Design: panels and battery options worked out in Easy PV Pro, including how many packs to start with.
- Installation: our own DBS-checked team; homes usually take one to three days.
- Aftercare: an annual system health check and a dedicated support line through The Solar Owners Club.

We are not loyal to a box. At the survey we look at your roof, your supply and your evenings, and recommend the maker whose equipment suits them.
Reviews
In our customers’ words.
-
Excellent service. Polite and friendly while carrying out the work. Very knowledgeable about their trade. After care five star too. Very helpful for helping me set up the app. I can't recommend them enough. Thank you for stress free and a lovely service.

Adam and Ellie are great to work with; they use sensible technology and are reasonably priced. Very pleased with everything they have done for me.
John K. Customer -
They fitted my panels, kept me informed about the process and Ellie and Adam are passionate about all that they do, great service at a great price.
Chris & Debbie G. Customer -
I couldn’t rate the quality and professionalism any higher.
Jon H. Google -
Finally, someone who responds, listens and helps in the solar world. Wouldn't hesitate to recommend.
M&J, Somerset Owners Club member -
Chuffed to bits with our upgraded system - working better than ever! Thanks guys.
P&M, Devon Owners Club member -
We've already saved the full membership cost in our battery upgrade alone! Great value for money.

OCEAN 2 is a newer range on EcoFlow’s UK site, listed alongside PowerOcean. It includes OCEAN 2 Single-Phase, OCEAN 2 Plus Single-Phase and OCEAN 2 Three-Phase, with lithium iron phosphate (LFP) batteries of 5 kWh and 8 kWh. The system we fit is PowerOcean; ask us about OCEAN 2 at your survey.
Each PowerOcean battery pack holds 5.1 kWh nominal, of which 4.8 kWh is usable. The three-phase system can grow to 45 kWh, by EcoFlow’s figure. We size the first stage around your household, not the maximum.
It can, where backup is included and suitable. With the EcoFlow Gateway fitted, the single-phase system’s switchover time is zero milliseconds under EcoFlow’s published test conditions, as the table above notes; for the three-phase system, its manual says backup loads switch over “within 20ms”. We’ll tell you plainly whether yours can.
EcoFlow’s single-phase datasheet rates the inverter and battery for dust, water and temperature as the table above shows, and the battery can stand on the floor or mount on a wall. We agree the right spot with you at the survey.
Next steps
Let’s talk about your project
If EcoFlow PowerOcean sounds like the right battery for your home, let’s start with the way your household uses electricity. We’ll explain how many packs would make sense now, how the system could grow, and whether backup is suitable for you. Call us, or use the form below, to arrange your free site survey.
