EcoFlow STREAM Basic System Set 2300W Output, 3.84kWh Storage and 1800W Solar

EcoFlow STREAM Basic System Set 2300W Output, 3.84 kWh Storage and 1800W Solar

This plug‑in solar plant bundle lets you harness and store your own solar energy without the complexity and cost of a grid connection or full rooftop solar. You can use this revolutionary system even if you live in a rented property.

Take advantage of our installation service and pay zero VAT on the system. Contact us for a quote. Available in London, the South-East and the Home Counties.

The bundle combines an EcoFlow STREAM Ultra 

with an EcoFlow STREAM AC Pro

Each of these devices includes a 1200W microinverter and 1.92kWh battery, giving you a total output up to 2300W and combined storage capacity of 3.84 kWh. The bundle delivers enough output to power common household appliances up to 2.3 kW. The EcoFlow STREAM Basic System Set 3.84 kWh can accept up to 2,000W of solar input power. Solar panels charge the batteries first, the batteries bridge any shortfall, and the grid only tops up the batteries when needed. When solar generation exceeds what you’re using, the surplus is stored in the batteries for later use. 

Bundle contents

• 1 × EcoFlow STREAM Ultra 1200W & 1.92kWh,
• 1 × EcoFlow STREAM AC Pro 1200W & 1.92kWh,
• 1 × EcoFlow STREAM parallel cable (0.55 m),
• 4 × DMEGC 450W bifacial rigid solar panels, and
• 1 x Set of solar cables and connectors.

Flexible and expandable

• Plug‑and‑play installation: Designed for straightforward setup – ideal for homeowners who want to manage their own solar without hardwiring. In the UK, any connection into your home’s distribution board must be carried out by a certified electrician.
• Expandable capacity: Each Ultra or AC Pro operates alone or in parallel. You can link up to six units together to increase storage from 1.92 kWh per unit to as much as 11.52 kWh. The price in this listing includes 3.84kWh of energy storage.
• High power output: When two STREAM AC/Ultra devices are linked with the parallel cable, they provide up to 2,300 W, enough to run hair dryers, kettles, washing machines and similar appliances on your own solar - without the expense of a full installation.
• Works in a power cut - use the two AC sockets at the back of the STREAM ULTRA to power your devices when the grid is down.
• Smart energy balancing: An AI‑driven system monitors connected units in real time and automatically balances loads, to maximise the use of your own solar energy
• Remote control and scheduling: Connect the system to Wi‑Fi and the EcoFlow app for remote control, historical energy data and smart time‑of‑use scheduling. Charge batteries using low-cost night tariffs and use AI to maximise solar generation based on predicted weather.
• Mounting options: Pair this system with our range of mounting kits for flat roofs, balcony, fence and facade mounting, or ground mounting. Need to mount on a different surface? Just contact us for a tailored quote.
• Software and accessories: Optional smart meters and smart plugs let you monitor surplus power, automatically switch devices and make the most of the solar energy you generate.

• Compatible with leading smart home control systems like Shelly.
• Compatible with third party solar panels.

Built to last

• Long‑life LiFePO₄ battery: Uses lithium iron phosphate cells rated for up to 6,000 cycles with 70 % capacity retention, giving up to around 15 years of use. EcoFlow backs the system with a 10‑year warranty.

• Quiet and weather‑ready: Whisper‑quiet operation (as low as 30 dB). Self‑heating technology keeps the units running down to −20 °C, and the IP65‑rated housing protects against rain and dust.

• Safety features: Flame‑retardant casing, multi‑layer overload and overheat protection, anti‑backfeed circuitry, rapid voltage drop on disconnection and smart battery management provide peace of mind. 

• Easy installation: The system is easy to install and maintain. Wiring the DIY cable into your distribution board or home circuits must be carried out by a certified electrician. The person installing must follow guidance 

How to connect the STREAM Power Plant to the Home Electrical Wiring

To comply with UK wiring regulations, the BKW-AC cable (which connects the inverter output to the home 230V wiring) must be connected to a fused spur - the white box shown to the right of the sockets in the photo below. Inside this box, the cable should pass through a 13A fuse and switch before being connected to one of the home circuits. In the photo, it is connected to the same circuit that powers the adjacent socket, but the installation does not need to be next to a socket. A blank plate can also be used to replace an existing socket.
