Best forEarly adopters wanting one vendor for battery, smart panel, EV charging, and solar at whole-home scale.
EcoFlow's 2026 leap from portable stations into permanently-installed storage, and on paper it's a monster: 10kWh IP67 modules stacking to 80kWh per inverter, a hybrid inverter platform rated to 24kW output with 205A LRA motor-start, 40kW of solar input, an integrated Smart Electrical Panel 40 and 11.5kW EV charger, plus a 15-year warranty that beats everyone except Enphase's on paper. Pricing is quote-only through certified installers - the price shown is an estimated installed starting system (inverter + battery + smart panel) based on early published system ranges; treat it as directional, not gospel. One early owner reports the AI-driven time-of-use optimization working well; the cautions are a brand-new installer network, unproven long-term support for installed products from a portable-power company, and unknown service logistics.

Summarised from owner discussions and forums
The OCEAN Pro is EcoFlow's first permanently installed whole-home system: a 24kW hybrid inverter, 10kWh IP67 battery modules that stack to 80kWh, a Smart Electrical Panel and an optional 11.5kW EV charger, all sold through certified installers. The people asking about it are comparing it with Powerwall 3 and Enphase, existing EcoFlow owners on Delta Pro Ultra and Smart Home Panel 2 who want grid-tie and solar backfeed, and households that want the whole house backed up rather than a handful of circuits. The draw is the power and expansion: one shopper pointed to solar and generator input at the same time and 80kWh of storage against 13.5kWh for a single Powerwall 3.
Installs began in late 2025, and early reports are positive. A first-week owner on a free-nights plan ran the house on battery from 5 to 9 pm using about a quarter of capacity and logged only a couple of self-clearing error messages, another confirmed it works alongside an existing SolarEdge inverter and runs the house in outages without a flicker, and a Gulf Coast owner with six battery modules has tested two Delta Pro 3 units on the generator port as extra reserve. Quotes run about $19,000 for panel, inverter and two batteries and about $24,000 with the EV charger, one owner paid $20,000 all in, and a 48-panel solar build with three batteries came to roughly $30,000 after the tax credit and a utility rebate in Texas. The concerns come largely from EcoFlow's other home products: support that answers quickly but confusingly, home systems that don't all work together, and a stated possibility of paid app features.
More power and expansion than a Powerwall 3 offers is the draw, and for owners already invested in EcoFlow gear it adds grid-tie and generator support their current setup lacks. Buyers who want to purchase hardware outright and choose their own electrician can buy Anker's E10 and Power Dock from retailers, which they cannot do with the OCEAN Pro, and at least one household that waited for open sales went with the E10 instead.
