Plug-In Solar Buying Guide

What to consider before buying, and how to get the best price when you're ready.

What to look for

  • Output: UK regulations allow up to 800W. Most balcony kits are 400–800W — match the size to your available space and energy usage.
  • Certification: Make sure the micro-inverter carries CE or UKCA markings with G98 anti-islanding protection. This is a legal requirement.
  • Mounting: Check what's included. Balcony brackets, ground stands, and flat-roof mounts all work differently. Renters should look for non-permanent fixings.
  • Warranty: EcoFlow offers 5 years on most kits. Some third-party sellers offer less — always check before buying.

Where to buy

We recommend buying direct from the EcoFlow UK store. You get the full manufacturer warranty, UK-based support, and access to any current promotions.

Amazon also stocks EcoFlow kits, but prices and seller warranties can vary.

Getting a better price

If you'd like to reduce the cost, here are a couple of options:

1

Use a cashback site

TopCashback currently offers 5.25% cashback on EcoFlow purchases. New members also get a £10 bonus.

2

Get 10% off with a referral

EcoFlow's referral programme gives new customers 10% off their first order. This link applies the discount automatically at checkout.

3

Wait for seasonal sales

EcoFlow typically discounts kits during Black Friday, Prime Day, and summer sales events. If you're not in a rush, it's worth waiting.
