Aferiy describes the PS240 as an “all-in-one design with integrated battery, micro-inverter and solar controller”, sold through its UK store and on Amazon UK. It's marketed as a balcony solar system with a “plug-and-play design”. Under the UK rules a box with a battery inside can't be a plug-in solar device, so the useful questions are what it does well and what you can lawfully do with it.
Aferiy PS240 specs
From Aferiy UK's product page, read on 8 October 2026:
| What it is | Battery, microinverter and solar controller in one box |
|---|---|
| Model | AF-PS240; expansion battery AF-PS240-B |
| Battery | 1,958 Wh LiFePO₄ (EVE cells), up to 9,790 Wh with expansion batteries |
| Cycle life | Up to 6,000 cycles |
| Solar input | Four MPPTs; up to 2,000 W on one unit, 2,400 W with an expansion battery |
| On-grid output | 800 W, which Aferiy qualifies as "potential grid functionality where permitted by law" |
| Off-grid output | 1,200 W; USB-A QC3.0 (18 W) and USB-C PD (100 W) |
| Backup switchover | 10 ms |
| Weather rating | IP65, minus 20 to 55 degrees C |
| Weight and size | 23.5 kg, 468 × 312 × 242 mm |
| In the box | 5 m AC cable with plug (plug type not stated), output cable with aviation connector, L-shaped wall brackets |
| ENA register | No record of any type |
Two details stand out. The 2,400 W solar figure in Aferiy's headline needs an expansion battery; one unit takes 2,000 W. And the plug on the 5 m AC cable isn't named anywhere we looked, so we can't tell you whether it's a UK BS 1363 plug or a European Schuko. Aferiy's PDF manual is mostly images, and we couldn't verify anything further from it.
The “UK Compliance Ready (G98*)” badge
Aferiy's UK product page carries this box, in full:
“UK Compliance Ready (G98*). Certification Applies To Specific Components Or Configurations Only. Grid Connection Subject To UK Regulations. Off-Grid Use Recommended.”
G98 is the engineering recommendation for connecting small generators, solar inverters among them, to the local network, and type-tested devices are listed on the ENA Type Test Register. We downloaded every record on the register on 8 October 2026, all device types, and searched for Aferiy, PS240, PS-240 and AEC, the name of Aferiy's app. Nothing came back. The asterisk and the line about specific components may explain the gap, but we couldn't find a register record behind the badge.
The Amazon UK listing goes further than Aferiy's own page. It claims “BV certification complying with UK standards”, an output “expandable to 1200W with local electricity supplier agreement”, and “simple plug-and-play installation that requires no professional skills”. Those are the listing's words. BV certification isn't ENA register verification, and none of those claims is backed by a register record.
Aferiy's own “different approach” wording
Aferiy's UK blog, in a beginners' guide to balcony solar published on 15 September 2026, says the PS240 stores solar energy during the day for use later, “making it a different approach from a basic plug-in solar setup.” The same article says that “battery storage or a portable power station can provide additional flexibility, but these are separate from the plug-in solar system itself.”
Read alongside “Off-Grid Use Recommended”, Aferiy is telling UK buyers fairly plainly that the PS240 isn't a plug-in solar kit in the legal sense.
The UK plug-in rule
The plug-in rule in one line
SI 2026 No. 848, in force since 27 August 2026, lets a plug-in solar device of up to 800 VA go into an ordinary socket. The government's Interim Product Specification says it “does not apply to other technologies including but not limited to … Plug-in battery systems; Plug-in solar PV devices integrated with battery systems”, and that “a device being submitted for registration shall not, in itself, be regarded as demonstrating compliance.” The PS240 has a battery and no record, so it fails on both counts.
What it means for a UK buyer
- Use it off-grid. Charge it from panels and run things from its off-grid output, up to 1,200 W. That's what Aferiy recommends, and it doesn't touch your house wiring. Our guide to power stations against plug-in solar covers where that line sits.
- Don't plug its grid output into a socket. Whatever the listing says about plug-and-play, that isn't the UK plug-in route.
- Grid connection means an electrician. A battery unit goes in as a conventional installation with a G98 notification to your network operator (our DNO finder tells you who). With no register record for the PS240, ask an electrician whether they can connect it at all before you buy for that purpose.
- Ask Aferiy which plug ships. We couldn't confirm it, and it matters even for charging from the mains.
One separate point, about a different product. Aferiy UK publishes a compliance update about its AF-P010, a portable power station, after a batch was flagged by UK Customs in May 2025 over labelling, address and instruction issues, which Aferiy says it rectified. It doesn't concern the PS240.
Alternatives on this site
- A kit you can plug in yourself. 120 kits were Compliant under Plug-in Solar at the last check of our register tracker, and the best balcony solar kits picks from them.
- A registered balcony battery. The EcoFlow STREAM Ultra X is on the register as an energy storage device, ready for an electrician's G98 notification.
- The battery rules. Our battery rules explainer and battery storage guide, plus how to check a kit is legal.
Where to buy
Aferiy sells the PS240 in five capacities and the PS240-B expansion battery on its UK store, with free delivery to mainland UK. Its prices change with its sales, so check the store on the day. The Amazon UK listing we found is titled as a PS240 with one PS240-B, so check which option you're choosing.
Frequently asked questions
Is the Aferiy PS240 legal to plug in in the UK?
Not as a plug-in solar device. Since 27 August 2026 the plug-in route covers only devices verified Compliant on the ENA register as Plug-in Solar, with no battery. The PS240 holds a 1,958 Wh battery and has no register record. Aferiy's own UK page says "Off-Grid Use Recommended".
What does Aferiy's "UK Compliance Ready (G98*)" badge mean?
Aferiy's small print says "Certification Applies To Specific Components Or Configurations Only" and "Grid Connection Subject To UK Regulations". We searched every record on the ENA Type Test Register on 8 October 2026 for Aferiy, PS240 and the app name, and found nothing. So the badge isn't backed by a G98 type-test record we could find.
Can I use the Aferiy PS240 off-grid?
Yes. Charged from up to 2,000 W of panels, it can run appliances from its off-grid output at up to 1,200 W. Nothing is connected to your house wiring that way, which is the use Aferiy itself recommends for UK buyers.
What plug does the Aferiy PS240 come with?
We couldn't confirm it. Aferiy lists a 5 m AC cable with plug in the box but doesn't say whether it's a UK BS 1363 plug or a European Schuko. The manual is mostly images, so it didn't settle the question.
How big can an Aferiy PS240 system get?
Aferiy sells it in five sizes, from 1,958 Wh to 9,790 Wh, by adding PS240-B expansion batteries of 1,958 Wh each. Solar input rises from 2,000 W to 2,400 W once an expansion battery is added.
When did the Aferiy PS240 launch in the UK?
We couldn't confirm a launch date. Aferiy hasn't published one that we found, and the dates on its store listing are listing data, not an announcement. It's on sale on Aferiy UK's store and on Amazon UK.
