How to Install EcoFlow STREAM: Step-by-Step UK Guide

A complete walkthrough of installing the EcoFlow STREAM plug-in solar kit on a balcony, garden, or flat roof in the UK.

Before You Start

You'll need about 30-60 minutes and no specialist tools. The EcoFlow STREAM comes with everything required — panels, inverter, cables, mounting hardware, and a BS 1363 plug with 5A fuse.

Check these prerequisites:

A suitable location — balcony, garden, or flat roof
A 13A wall socket within cable reach — no extension leads allowed
WiFi coverage at the inverter location (for app monitoring)
Ideally south-facing with minimal shading

Step 1: Choose Your Location

The best output comes from panels facing south at 30-35° tilt. Use our panel angle guide to optimise for your setup. For balcony railings, the tilt is typically limited to the railing angle (usually ~70-80°), which reduces output by about 30% compared to optimal.

Step 2: Mount the Panels

The STREAM kit includes mounting hardware for three scenarios:

Balcony railing: Clip the mounting brackets onto your railing (fits 20-80mm rails). Secure with the included tool-free clamps. Each panel weighs approximately 20kg — manageable alone but easier with help.

Garden / ground: Use the included ground stands. Position on a flat, stable surface. The adjustable tilt brackets let you set the optimal angle. Consider using the ballast mounting approach for windy locations.

Flat roof: Similar to garden mounting but elevated. Ensure panels are secured against wind — check our storm-proofing guide.

Step 3: Connect the Cables

Connect each panel's MC4 output cable to the STREAM inverter's MC4 input
Check polarity — positive to positive, negative to negative
Secure cables with the included cable ties
Route cables neatly using cable management best practices

Step 4: Position the Inverter

Place the STREAM inverter:

Within cable reach of both panels AND a wall socket
In a ventilated location (it generates some heat)
Protected from direct rain if outdoors (IP67 rated but shelter extends lifespan)
Within WiFi range

Step 5: Plug In

Connect the STREAM's AC cable directly into a 13A wall socket. The 5A fuse in the BS 1363 plug is pre-fitted — don't replace it with a higher-rated fuse.

The system starts generating immediately when plugged in during daylight hours.

Step 6: Set Up the App

Download the EcoFlow app and follow the app setup guide. You'll need:

Your home WiFi network name and password
A free EcoFlow account (email registration)

The app shows real-time generation, daily/monthly totals, and lets you configure smart scheduling for the battery (if included).

Step 7: Notify Your DNO

Within 28 days, you must notify your Distribution Network Operator under G98 rules. This is a simple online form — it doesn't require a site visit.

Common Installation Mistakes

Using an extension lead — this is prohibited by the IPS v2
Wrong panel angle — too steep (like a wall mount) reduces output significantly
Shading from nearby objects — even partial shade dramatically cuts output
Poor cable routing — exposed cables degrade and create trip hazards
Forgetting DNO notification — legally required within 28 days

Do I need to tell my landlord?

For renters, it depends on your tenancy agreement. Balcony-mounted panels don't modify the building structure, but check your AST for clauses about external fixtures. The Renters' Rights Act 2025 strengthens your position.

Can I install it myself?

Yes — that's the entire point of plug-in solar. No electrician required. Just plug into a wall socket.

What if my socket is indoors and panels are outdoors?

Route the DC cables from outside to inside (through a window gap or purpose-drilled hole), and position the inverter near an indoor socket. See our cable routing guide.
