Description

The EcoFlow STREAM Ultra X is a plug-and-play home solar battery system: it stores solar energy and feeds it back into your home to cut your bill, with no electrician and no rewiring.

Who is this kit for?

For flats and houses that want to start self-consumption simply: produce, store 3840 Wh, and use it in the evening or during peaks. Install it yourself, manage it from the app.

Produce, store, save

With 3840 Wh of storage and up to 1200 W output, the system shifts your solar production to when you actually use it. The app shows production, storage and savings in real time.

Plug-and-play install

No electrician, no heavy works: you plug it in, pair it in the app and you are producing. It scales with extra batteries or panels as your needs grow.

Why buy from Vantour?

We work directly with EcoFlow, not as an anonymous stock reseller: a 100% genuine, official product, stock managed by the brand (real availability) and after-sales handled by the manufacturer for the longest cover possible.

On price, to give you a concrete idea: £1499,00 at the brand, and £1424,05 with our code CARO5 (-5% off).

The code applies on its own, and we keep all the latest EcoFlow offers up to date.
