One module on a balcony
You have one module in the stated 355–670 W band and you can accept a short review file. The elejoy EGMI-500 is about £99.99, with 4.8 from seven reviews and a 230 V AC field. It does not name a BS 1363 plug.
The best micro inverters, compared.
Top pick: elejoy EGMI-500 – Highest stored score in this set, 96, from 4.8 across seven reviews, three of them from the United Kingdom. Seven reviews are still a small sample, and no UK 13 A plug is named. Best value: VKY NEP 800 W – Lowest shelf price with a star line, about £92, score 74. The output-voltage field says 60 V DC, and the reviews are not from the United Kingdom. Updated October 2026.
A micro inverter turns direct current from one photovoltaic module, or a pair of modules, into alternating current that runs in parallel with the UK mains. You buy one so each module can track its own output, on a balcony, a flat roof or a small array. The plug-in route is a maximum rated AC output of 800 W into one fixed BS 1363 socket, with one device per customer installation. A hard-wired roof unit follows BS 7671. G98 is connect-and-notify for fully type-tested micro-generators up to and including 16 A per phase, 3.68 kW on a single phase. The checks that stay useful when the range on sale changes are in the [micro inverter buying guide](/hub/electrical-equipment/micro-inverter/sub/micro-inverter-buying-guide). Read the AC watts with the voltage and the frequency. UK mains are 230 V at 50 Hz, so a 120 V or 60 Hz field is outside this route. Two independent MPPT inputs suit two modules facing different ways, and one shared tracker does not. A grid-tie unit stops when the mains stop.

Question 1 of 2
How many modules are you connecting?
Across seven amazon.co.uk reviews at 4.8, the elejoy EGMI-500 is listed at £99.99 as a 500 W pure sine inverter, with an MPPT window of 22–50 V for one module from 355 W to 670 W and above. Three of those reviews are from the United Kingdom and call the setup easy, the case waterproof and the app clear. Two further reviews in the file are from Germany, and one of them says no EC declaration was found. The highlight says plug-and-play with Wi-Fi, Bluetooth and the Smart Life app, and it does not name a BS 1363 plug or a G98 line. One field prints 1.8 kg and a bullet prints 1.2 kg, and the warranty field is one year. It is the top pick in this set because the stored score is the highest, at the star line times 20, and seven reviews is still a small sample. It is a single-module listing, not a two-panel kit.
Pros
Cons
Best for: One module in the stated 355–670 W band, if you accept a short review file and no named UK plug
Less suitable: Two modules, or a socket install that needs a printed G98 model and a BS 1363 plug in the title
Specifications
Common questions
How many modules does the listing describe?
The bullet says a single solar panel from 355 W to 670 W and above, with an MPPT range of 22–50 V and a 22 V start.
Is a UK plug named?
No. The highlight says plug-and-play with Wi-Fi and Bluetooth. It does not name a BS 1363 plug.
What do the UK reviews say?
Three United Kingdom reviews call setup easy, the case waterproof, and the app clear. Two further reviews in the file are from Germany. One of those says no EC declaration was found.
Across 12 amazon.co.uk reviews, all of them from the United Kingdom, the Solarsys 800 W kit is listed at £139.99 with dual MPPT for two panels of 300–550 W, IP67, 230 V at 50 Hz, and a 3 m lead to a UK 13 A plug. Reviewers often praise that included lead. More than one could not find an approval listing, one names the hardware as Elecway VN2T, and one unit was reported dead after 23 days. The standards field says CE. A bullet mentions off-grid auxiliary use, while the same reviews say the inverter looks for grid voltage and stops in a power cut or on an isolated shed. Those reviews also say a 5 GHz Wi-Fi network is rejected and that the app can show zero while the unit is generating. The warranty field is one year against manufacturer defects.
Pros
Cons
Best for: Two modules on a lead that the title calls a UK 13 A plug, if you treat the register as still unchecked
Less suitable: An off-grid shed, a power cut, or a buyer who needs a confirmed ENA line in the listing
Specifications
Common questions
Does this listing include a UK plug?
Yes. The title says a 3 m AC cable with a BC01 female connector and a UK 13 A plug.
Will it run without the mains?
The bullet mentions off-grid auxiliary projects. United Kingdom reviews say the inverter looks for grid voltage and stops in a power cut or on an isolated shed.
What do the 12 reviews agree on?
All 12 are from the United Kingdom. Setup with the included lead is often praised. More than one reviewer could not find an approval listing, and one unit was reported dead after 23 days.
The VKY listing is an NEP 800 W inverter at £92, with IP67 in a bullet and one power cable in the box line. Across 26 amazon.co.uk reviews the star line is 3.7, and the saved review text is from Poland, Germany, Italy and the Netherlands, so it is not British experience. Reviewers describe Wi-Fi setup trouble, and several say the mains cable was missing. The output-voltage field prints 60 V DC, while the title is an inverter and the waveform field says pure sine. A bullet claims a 12-year warranty, expandable to 25, plus CE, and no UK 13 A plug is named. It is the best value here only as the lowest shelf price with a star line. The 60 V field still has to be settled before you treat the listing as a UK socket inverter.
Pros
Cons
Best for: Comparing an 800 W title at the bottom of this price file, while you still check the voltage field
Less suitable: A UK socket install that needs a named 13 A plug and a 230 V field
Specifications
Common questions
Does the listing name a UK 13 A plug?
No. The box line is one NEP 800 W inverter and one power cable. The plug face is not described.
What output voltage is in the specification field?
The output-voltage field says 60 V DC. The title is an 800 W inverter and the waveform field says pure sine.
Are the 26 reviews from the United Kingdom?
No. The reviews saved in the saved listing are from Poland, Germany, Italy and the Netherlands. Several describe Wi-Fi setup trouble or a missing mains cable.
The BATENORY listing is an 800 W dual-MPPT inverter at £129.99, with a 230 V field, a 5 m AC cable, IP67 and the Solarman app. The technical bullet gives an MPPT window of 25–55 V, a 60 V maximum input, 2 × 13.5 A and a maximum AC current of 3.47 A. A bullet claims UKCA and G98, and the warranty field says 10 years, with no certificate number printed. The file has no customer-review line, so there is no star score and no comment on whether the cable ends in a 13 A plug. The colour field says Schwarz. A G98 word in a bullet is not an ENA register line, and this file does not show one. The manufacturer field says Astro Energy.
Pros
Cons
Best for: A dual-input 800 W title at £129.99, if you will confirm the model on the ENA register before you buy
Less suitable: Anyone who needs review evidence, or a title that already names a UK 13 A plug
Specifications
Common questions
Does the listing claim G98?
Yes. One bullet says the inverter holds UKCA and G98 certifications. No certificate number is printed, and the file has no reviews.
Is the AC cable described as a UK plug?
The title and the box line say a 5 m AC cable. They do not say UK 13 A or BS 1363.
What input does the technical bullet give?
MPPT 25–55 V, maximum input 60 V, 2 × 13.5 A, short-circuit 2 × 16.5 A, maximum AC current 3.47 A, 800 W and 230 V.
The COAKUE title selects 800 W from a list running from 300 W to 1600 W, at £147.25, and the bullets claim IP65 plus a mobile app. The specification fields say 120 V AC and 60 Hz, and the peak-output field says 1200 W, so the title and the table disagree. Another bullet says 120 V and 230 V adapt automatically, and that the output turns off when the grid fails. The number-of-items field is 20. There is no customer-review line, no named UK plug, no standards claim and no warranty field. A 120 V, 60 Hz table is outside UK 230 V, 50 Hz mains, whatever the title wattage says.
Pros
Cons
Best for: Only a check against a listing whose own fields say 120 V and 60 Hz
Less suitable: A balcony or roof on UK 230 V, 50 Hz mains
Specifications
Common questions
Is this listed as 230 V and 50 Hz?
The specification fields say 120 V AC and 60 Hz. A bullet says 120 V and 230 V adapt automatically.
What power is printed?
The title selects 800 W from a list that also includes 300 W up to 1600 W. The peak-output field says 1200 W.
Does the listing say it stops if the grid fails?
Yes. One bullet says the output turns off when the power grid fails, and that input and output are isolated.
The PioMue title selects 1400 W at £160 from a four-wattage list, and it carries model number 1v5un-924923, the same number as the 1800 W PioMue row. The shared bullets claim automatic 120/230 V detection, IP65, self-cooling and an app, for 30 V or 36 V panels and 36 V batteries. The package line is 10 × 10 × 10 cm and the weight is 1 kg, which does not read as a 1400 W outdoor inverter. There is no review text, no 50 Hz figure, no UK plug and no standards field. On the title, 1400 W AC is already above the 800 W plug-in cap. You cannot treat this ASIN and the 1800 W ASIN as two separately tested models.
Pros
Cons
Best for: Seeing how one model number is titled at two wattages, not as a UK socket purchase
Less suitable: A balcony socket, or anyone who needs a distinct tested 1400 W unit
Specifications
Common questions
How is this different from the other PioMue listing?
This title selects 1400 W at £160. ASIN B0FVT3L5DS selects 1800 W at £164.22. Both use model number 1v5un-924923 and the same bullets.
What voltage does the bullet state?
Automatic 120/230 V AC detection, for 30 V or 36 V panels and 36 V batteries. No 50 Hz figure is printed.
Is there a review line?
No. The saved listing has no customer-review line and no review text.
The PioMue title at £164.22 selects 1800 W from a line that also prints 1200 W, 1400 W and 1600 W. Model number 1v5un-924923, the bullets and the image match the 1400 W listing in this file. IP65 and an app are claimed, and the package line is again 10 × 10 × 10 cm at 1 kg. The saved listing has no reviews, no BS 1363 plug and no standards field. An 1800 W title is outside the 800 W AC plug-in route. The shared model number means the wattage at the end of the title is a menu choice, not evidence of a second product.
Pros
Cons
Best for: Comparing a duplicate title, not buying a unit for a UK socket
Less suitable: Any balcony or roof install that needs one coherent wattage and a UK plug
Specifications
Common questions
Which wattage is the product?
The title prints 1200 W, 1400 W, 1600 W and 1800 W, and ends on 1800 W. The model number is the same as the 1400 W PioMue ASIN.
Does the file name a UK plug or a standard?
No. There is no BS 1363 line, no 50 Hz figure, and no standards field.
What size and weight are printed?
Package dimensions are 10 × 10 × 10 cm and item weight is 1 kg.
Seven amazon.co.uk micro-inverter listings are on this page. The stored score is the star line times 20. A listing with no customer-review line scores 0. That figure is not a lab test. The top pick is the highest score. Best value is the lowest shelf price that still has a star line, and not the highest score. Listing conflicts stay in the written assessment. They were not used to change the stored scores.
Amazon star line
100%The stored score is the amazon.co.uk star rating times 20. A listing with no customer-review line scores 0. A high score on seven reviews is still a small sample. Reviews that are not from the United Kingdom stay labelled as such. This is not a lab test.
Use this order before you compare prices. Confirm you want a grid-tie micro inverter, not a battery inverter for a van or a power cut. Read the AC watts with the voltage and frequency, then count independent MPPT inputs. Check the plug, the fuse and whether that exact model is marked compliant. Warranty, the app and whether the reviews were written in the United Kingdom come after those checks. A low shelf price does not repair a 120 V or 60 Hz field.
A micro inverter turns direct current from one photovoltaic module, or a pair of modules, into alternating current that runs in parallel with the UK mains. It is a grid-tie device. When the mains stop, it stops. It will not run a house during a power cut, a van, or a shed that is off the grid. A 12 V or 24 V battery inverter is a different category.

The plug-in limit is rated AC output, not the watts printed on the modules. A pair of large panels can sit well above the inverter's AC figure. The memorandum caps panels at 2,000 W DC, and Electrical Safety First asks for an assessment above 960 W DC.
A CE mark, a UKCA bullet or the word G98 is a claim until the ENA register shows that model as compliant. Submitted is not compliant. In the same pass, read the voltage and frequency fields. A 120 V or 60 Hz row is not UK mains, whatever the title wattage says.
The plug-in case is one device per customer installation. Adding another socket inverter is outside that rule. A grid-tie unit stops when the mains stop. An off-grid line in a bullet does not make it run a power cut, a van or a shed that is not on the mains.
Read alternating-current watts and the voltage fields together. The plug-in route is a maximum rated AC output not exceeding 800 W, into a fixed BS 1363 socket. A title of 1,400 W or 1,800 W is already above that cap. Panel watts are not the cap. The cap is the rated AC output. UK mains are 230 V at 50 Hz. A specification field that says 120 V or 60 Hz is outside that route, even if a bullet says 120 V and 230 V adapt automatically.
Check the plug, the fuse and the register before the price. The plug-in route needs a non-rewirable BS 1363-1 plug with a BS 1362 fuse of 5 A or less. A box line that says only a power cable, or a 5 m AC cable, does not name that plug. Outdoor parts need at least IP55. A CE mark, a UKCA bullet or the word G98 is a claim until the ENA register marks that exact model compliant. Submitted is not compliant. No certificate number in a bullet is not a register line.
Three typical situations, each with a recommendation from this comparison.
You have one module in the stated 355–670 W band and you can accept a short review file. The elejoy EGMI-500 is about £99.99, with 4.8 from seven reviews and a 230 V AC field. It does not name a BS 1363 plug.
You are connecting two modules of 300–550 W and you want a title that names a UK 13 A plug. The Solarsys 800 W kit is about £139.99, with 4.1 from 12 United Kingdom reviews. Reviewers could not find an approval listing, so the register is still your check.
You are comparing the bottom of this price file and you will read the voltage field before you buy. The VKY NEP 800 W is about £92, with 3.7 from 26 reviews that are not from the United Kingdom. The output-voltage field says 60 V DC.
In this set of seven amazon.co.uk listings, the top pick is the elejoy EGMI-500 at about £99.99. The stored score is 96, from 4.8 across seven reviews, three of them from the United Kingdom. It is a 500 W single-module listing with a 230 V AC field, a one-year warranty field, and no named BS 1363 plug. Best value is the VKY NEP 800 W at about £92, score 74, because it is the lowest shelf price that still has a star line. The output-voltage field says 60 V DC, and the 26 reviews are not from the United Kingdom. Neither score is a lab test. A grid-tie unit stops when the mains stop.
