What does an EcoFlow OCEAN Pro really cost in 2026?

EcoFlow doesn’t publish a price. It sells the OCEAN Pro only through installers, and none of the 425 products in its U.S. online store is an OCEAN item. So we gathered every real dollar figure we could find, with the date we found it.

What else goes into an installed price

• A certified installer. EcoFlow says the OCEAN Pro “requires certified installer with local utility & authority having jurisdiction approval.”
• A smart panel or gateway. It decides which circuits stay on in an outage. EcoFlow’s 8-circuit panel also carries 32 standard circuits.
• Permits. Houston needs only a service-connection permit now. Dallas still reviews zoning, building and fire, with a $577 plan review fee plus inspection fees. See the permit rules.
• Extra electrical work. An older panel or a long wire run can add to the quote. Ask for it in writing before you sign.

Pick a size. This adds up the inverter and batteries at the prices two online stores showed on Oct 15, 2026. It’s the floor of your cost, before the panel, labor and permits.

Yes, if you own a house with no solar in parts of Houston or Dallas-Fort Worth. It’s Energywell’s program, and it’s a trade: Energywell installs and owns the battery, and you buy your electricity from Energywell.

Get these 4 things in writing

1. 1
   The brand and size

   Energywell’s pages say OCEAN Pro, but its agreement says the company “will select the brand and model.” Ask for “EcoFlow OCEAN Pro” and your kWh on the paperwork.

2. 2
   Your usage can go up

   Energywell’s terms say your use “may increase,” because it may charge the battery from the grid. You pay for that power.

3. 3
   Keep the Wi-Fi on

   The agreement needs a working internet link. If the company loses access, a fee of $5 a day can apply, up to $100.

4. 4
   The 20% reserve is a goal

   Energywell makes “reasonable efforts” to keep 20% charged for outages. The agreement says that isn’t guaranteed.

It’s a whole-home battery that’s wired in for good, not a plug-in power station. Here’s what EcoFlow’s own datasheets say, and what each number means for a Texas house.

EcoFlow launched the OCEAN Pro in the U.S. on July 15, 2025. Its launch notice says it was built with states like California, Texas and Florida in mind, and that it builds on EcoFlow’s PowerOcean system sold in Europe.

It depends on three things: how many batteries you have, how full they are, and what you run. Central AC is the big one. Try it.

How many batteries do you need?

• A day of basics: about 1 kW for 24 hours is 24 kWh, so three batteries (30 kWh).
• Central AC overnight: about 3 kW for 12 hours is 36 kWh, so four batteries (40 kWh). That’s the most Energywell’s program installs.
• A long outage: plan on a recharge. Solar or a 2.5–10 kW generator can refill the batteries.

Most homes don’t need to back up everything. The smart panel picks the circuits that stay on, so your fridge and AC keep runing while the dryer waits. For more on what to do when the lights go out, see who to call in a Texas power outage.

Both are EcoFlow batteries, but they’re built for different jobs. The OCEAN Pro is wired into your home by an installer. The DELTA Pro Ultra is a portable unit you can plug in and take with you.

Which EcoFlow name is which?

• OCEAN Pro: the installed whole-home system on this page, sold in the U.S. since July 2025.
• PowerOcean: EcoFlow’s home battery line in Europe. EcoFlow says the OCEAN Pro builds on it, with “over 17,000 installations across Europe.”
• DELTA Pro Ultra: the portable, stackable power station sold on EcoFlow’s store.
• DELTA Pro Ultra X: the model EcoFlow compares with the OCEAN Pro on its own page. EcoFlow says it’s “typically installed within 7 days of delivery.”

Not if you buy it for your home. The IRS says the 30% homeowner credit “is not available for any property placed in service after December 31, 2025.”

Two takeaways. If you buy an OCEAN Pro yourself, price it with no federal credit. And if a seller’s math still counts a 30% credit for a 2026 install, ask them to show you the IRS rule. This page isn’t tax advice, so check with a tax pro for your situation. More on the change: what solar costs in Texas without the credit.

EcoFlow covers the battery, inverter, smart panel and meter backup switch for 15 years. The battery should keep at least 70% of its capacity after 15 years or 6,000 charge cycles.

The 3 lines to read before you buy

1. 1
   Flood-resistant isn’t flood-covered

   EcoFlow says the OCEAN Pro can withstand up to 3.3 feet of water. Its warranty still excludes products “damaged by fire, flood, lightning” and other force majeure events. In a Houston floodplain, ask about placement and your home insurance.

2. 2
   Buy it through an installer

   The warranty is for first buyers who purchase “through an installer,” in the U.S. It starts on the day the products are delivered.

3. 3
   In a $0 program, the company owns it

   Energywell’s agreement says the company “makes no warranties” itself. It passes the maker’s warranty to you “to the extent assignable,” and it repairs the battery during the 15 years.

Usually, but less than before. Since Sept. 1, 2025, a state law (SB 1252) says Texas cities can’t regulate or inspect a home backup system of 50 kW or less, or 100 kWh or less. One OCEAN Pro inverter is 24 kW.

Where it can go in your home

Model codes cap home battery storage by location, unless fire-test data allows more. By UL’s summary of those codes: 20 kWh per unit, 40 kWh in a utility closet, basement or storage space, and 80 kWh in a garage, on an outside wall or outdoors. Each OCEAN Pro module is 10 kWh. EcoFlow’s guide also says that in a garage, “keep it away from the driveway.”

Your install checklist

• A licensed electrician does the wiring. You can look up any Texas license with TDLR.
• The permit is pulled and the inspection passes before your utility reconnects you.
• Shade and space. It cuts power above 113°F, so skip a west wall in full sun.
• Floodplain check. In Houston, the city says to contact its Floodplain Management Office first if your site is in a floodplain.
• Utility approval if you add solar, so the system can connect to the grid.

Maybe, but don’t count on EcoFlow’s savings example. It’s modeled on a California home with 11 kW of solar, a 20 kWh battery and the California utility PG&E’s 2025 export rate.

• No solar? A battery alone mostly buys backup, not savings. It can save money only if your plan charges less at some hours than others.
• With solar, what you’re paid for extra power depends on your plan. See how Texas solar buyback plans work.
• Grid programs are growing. ERCOT’s pilot for groups of home batteries reached 293 of its 500 MW cap by Sept. 25, 2026, “driven largely by residential battery installations.”

On paper, it’s one of the strongest home batteries you can buy: big power, a 15-year warranty and an outdoor rating. The hard part is the price, and in Texas that’s the part you may be able to skip.
