Top pick: Fit4Less 1500W 24V pure sine inverter Best value: elejoy EGMI-500 500W micro inverter – Lowest-priced micro with a stated 22–50 V MPPT window, about £99.99, 4.8 from 7 reviews. Score 59. No 13 A plug is named, and the standards field is CE only. Updated October 2026.
A solar inverter turns panel direct current into alternating current for a UK home, van or off-grid circuit. On amazon.co.uk that name covers a grid-tied micro, a hybrid that charges a battery, and a battery inverter for a 12 V, 24 V or 48 V bank. A battery inverter does not replace an MPPT charger.
Match the class, the PV window and open-circuit limit, a continuous AC rating the weight supports, and pure sine if you run electronics. Look for 230 V at 50 Hz and a BS 1363 plug or proper terminals. From 27 August 2026, compliant plug-in solar in Great Britain is 800 W registered capacity, one unit per installation, and you still notify the network operator. Northern Ireland still needs its own change.
G98 is fit-and-notify up to 16 A per phase, about 3.68 kW at 230 V. A G98 sentence is not a type-test number, and a grid-tied micro does not keep the house on in a power cut. The [solar inverter buying guide](/hub/electrical-equipment/solar-inverter/sub/solar-inverter-buying-guide) sets out class, voltage and grid role before you compare listings.

The Fit4Less listing is a 24 V to 230 V pure sine inverter at £89.99, with one BS socket, an LCD, USB and USB-C, and a fan that stays off below 35 percent of rated power. The published line is 5.0 from 1 review, and the saved listing has no review text, so there is nothing on heat, cable fit or a real load. The title and bullets say 1,500 W continuous and 3,000 W peak, while the wattage field says 1,000 W. The battery-capacity field says 100 Ah, which is not a battery built into the inverter. Power source is described as solar and battery, and no MPPT voltage window is printed. At 3.18 kg it is a compact 24 V box, and one silent star is too thin to show which wattage figure holds.
Pros
24 V in and 230 V out, with one BS socket, at £89.99
LCD shows voltage, frequency, power and battery level
Fan stays off below 35 percent of rated power
USB and USB-C are stated on the listing
Cons
5.0 from 1 review and no review text
Title says 1,500 W and the wattage field says 1,000 W
No MPPT window is stated
Best for: A 24 V vehicle bank, if you confirm which continuous wattage is on the unit you receive.
Less suitable: Anyone who needs UK review evidence, or a solar input rather than a battery inverter.
The elejoy EGMI-500 is a 500 W pure sine micro inverter at £99.99, with an MPPT window of 22–50 V and a 22 V start, for a single module the listing puts between 355 W and 670 W or more. It shows 4.8 from 7 reviews. UK comments call the setup easy, the app clear on a small array, and the waterproofing in line with the IP65 claim. The input-voltage field also says 60 V, the bullets say 1.2 kg while the item weight is 1.8 kg, and the browse node files it under hybrid inverters. No UK 13 A plug is named in the box, and the standards field is CE, with no G98 string in the file. A review from Germany, which is not a UK opinion, says a 400 W module ran warm and that an EC sheet was hard to find. It is the best value in this set when you want the lowest-priced micro that already has a handful of UK reviews, and you still have to supply the AC lead and check any approval yourself.
Pros
500 W micro with a stated 22–50 V MPPT window at £99.99
4.8 from 7, with UK notes on setup and the app
IP65 and a fanless housing are claimed, and one UK review agreed on waterproofing
Night consumption is claimed under 50 mW
Cons
No 13 A plug or AC lead is named in the box
No G98 reference in the file
Bullets say 1.2 kg and the item weight says 1.8 kg
Only seven reviews
Best for: A single module inside 22–50 V, if you already have a suitable AC connection and you are not treating CE as a type test.
Less suitable: A two-panel kit that needs the UK lead in the carton, or anyone who wants a published G98 reference.
The Novopal title is a 4,000 W pure sine inverter, 12 V to 240 V, at £339.89 and 9.32 kg, with two UK outlets, a USB port and a wired remote listed as 16.4 ft. The listing shows 4.5 from 384 reviews, and many of the stored texts describe a 1,500 W, a 3,000 W or a 24 V Novopal rather than this 4,000 W 12 V unit. Praise of quiet running, the LCD, and kettles or microwaves therefore belongs to that mixed pool, not to a confirmed test of this wattage. A 4,000 W load on 12 V is on the order of several hundred amps before losses, and the listing does not state an MPPT window. One text in the pool says a previous Novopal of another size shorted the battery input. The battery field says 260 Ah, which reads as a suggested bank, not a battery in the box. You are paying the highest battery-inverter price in this set for a star line that does not isolate this model.
Pros
Two UK outlets and a wired remote are in the box contents
Pure sine is stated, with a 1-year defect warranty
Spare fuses, a spanner and a ground cable are listed
4.5 from 384 is a large line, if you accept that the texts mix other models
Cons
Stored reviews often name other Novopal wattages or 24 V
No PV input is stated
4,000 W at 12 V implies a very large battery current
£339.89 is the dearest battery inverter in this set
Best for: A 12 V workshop or vehicle bank only if the unit in the box is the 4,000 W model the title describes.
Less suitable: A solar string, or anyone who would treat all 384 reviews as reports on this wattage.
The Renogy R-INVT-PUH1-101235-UK is a 12 V battery inverter rated 1,000 W continuous and 2,000 W peak, at £113.99, and UK reviewers have used it for 230 V circuits in a van, including a 1,000 W induction hob. Across 163 amazon.co.uk reviews it sits at 4.4, the largest battery-inverter sample in this set. Owners describe a straightforward setup, a useful remote on/off switch, and use with lithium batteries plus separate panels, because this listing states no MPPT window. The title says 240 V AC while the output-voltage field says 230 V AC, and the bullets say a 2-year warranty while the warranty field says 1 year. Fan noise is inconsistent between two units doing the same job, and the earth bolts are described as tiny. One unit died within 30 minutes and was replaced after an installation dispute, and another smoked on a 650 W heater after about 15 months, which that reviewer treats as outside a 1-year warranty. It is a van and motorhome inverter, and it does not take a solar string on its own.
Pros
1,000 W pure sine with two UK sockets at £113.99
4.4 from 163, the largest battery-inverter sample here
Reviewers ran van 230 V circuits and a 1,000 W induction hob
Remote on/off is listed in the box
Cons
No PV or MPPT input is stated
Title says 240 V and the output field says 230 V
Warranty printed as 2 years and as 1 year
Fan noise, tiny earth bolts, and a failure on a 650 W heater after the cited warranty window
Best for: A 12 V camper or boat bank that already has its own charge controller, if you want UK sockets and a remote switch.
Less suitable: A balcony or roof string that needs an MPPT window, or any grid-tied connection.
The Y&H RS-3200W-24V-M80A-UK is a 24 V hybrid at £255.99, with an MPPT window of 55–450 V, a 450 V open-circuit limit, a start above 60 V and an 80 A charge rate, and the bullets put the array at up to 3,000 W. UK reviewers, five texts against a listing count of 8 and a 4.4 score, describe battery settings, mains charging for continuous running, and daytime solar that still needs a real battery at night. The output-power field says 3,000 W while the title says 3,200 W. Wi-Fi is not clearly in the box: reviewers bought a dongle elsewhere, and they called the Sun House app poor, with updates about every five minutes and little history. Bluetooth monitoring is described when you stand close to the unit. Standards are CE only, with no G98 or G99 reference, and the AC side is terminals rather than a 13 A plug. It is the hybrid in this set that UK reviewers describe as running, with the monitoring extra left out of the price.
Pros
24 V hybrid with a 55–450 V PV window and an 80 A charger
4.4 from 8, and UK texts describe it running on sun plus a battery
Mains and solar charging modes are listed, including a battery-less start claim
A 2-year manufacturer warranty is stated
Cons
The Wi-Fi dongle is not clearly included
A reviewer called the Sun House app poor
The title says 3,200 W and the output-power field says 3,000 W
CE only, and the AC output is terminals rather than a plug
Best for: A 24 V bank whose panels sit inside 55–450 V, if you buy the dongle separately and keep the unit off-grid unless a competent person says otherwise.
Less suitable: A plug-in balcony, or a grid-parallel install you hoped the UK model suffix had already approved.
The Solarsys kit is an 800 W pure sine micro inverter at £139.99, with dual MPPT for two modules the listing puts at 300–550 W each, a 3 m AC cable and a UK 13 A plug. It shows 4.1 from 12 reviews. Owners describe straightforward wiring on a log cabin with 540 W modules, a garden-office setup that worked, and instructions in the kit. One reviewer compared yield with an Enphase IQ8HC and reported about half the energy, another called the app awful and said good Wi-Fi was essential, and a third was not sure of ENA approval while using the unit islanded. One unit died after 23 days, having worked for 22 days on two 400 W panels. The manufacturer field says Elfcam, the standards field is CE, and there is no G98 reference number. It is the top pick in this set because it is the grid-tie micro with a UK 13 A lead and the largest review sample in that class, not because a lab or a type-test register was checked.
Pros
800 W dual MPPT with a 3 m lead and a UK 13 A plug at £139.99
4.1 from 12, with notes on cabin and garden-office installs
IP67 is claimed, and the kit states 230 V at 50 Hz
Start-up is claimed from 18 V
Cons
One unit dead after 23 days on two 400 W panels
One comparison reported about half the yield of an Enphase IQ8HC
The app is criticised, and ENA approval was unclear to a reviewer
No G98 reference number, and the manufacturer field says Elfcam
Best for: A two-module daytime setup, if you will check the register for the exact kit and you can accept a 12-review sample that includes an early failure.
Less suitable: Night-time loads, a proven type-test number, or anyone who needs the unit to run in a power cut.
The Spark SM3V12AT is a 12 V modified sine inverter titled 3,000 W continuous and 6,000 W peak, at £184.99 and 5 kg, aimed at a motorhome. It shows 3.9 from 19 reviews. One reviewer ran an air fryer and called the price fair, and the listing itself says a full load needs about 250 A and cable around 70–95 mm², which that reviewer echoed. The same listing excludes CPAP, active power-factor correction, laser printers and some motors. One UK review says the delivered unit burst into flames on connection, and another says the remote did not work. The wattage field says 6,000 W against a 3,000 W output, and the output-voltage field says 215 V against a 240 V title. There is no solar input. A fire report in a 19-review sample is the reason to leave it unless you already accept modified sine and that battery current.
Pros
Modified sine is stated on the listing, so the waveform is not hidden
The listing states the 250 A and 70–95 mm² full-load case
One reviewer ran an air fryer
A remote LCD and battery cables are in the box contents
Cons
One UK review describes the unit bursting into flames on connection
A remote failure is reported
The listing excludes CPAP and active power-factor correction
The output field says 215 V against a 240 V title, and there is no PV input
Best for: A 12 V motorhome load the listing already allows, if you size the bank for about 250 A and you have read the fire report.
Less suitable: CPAP, sensitive electronics, a solar string, or anyone who wants pure sine.
The Y&H SUN-6.2KW-HV-UK is a 48 V hybrid at £399.99 and 14.5 kg, with bullets of 6,200 W continuous, a PV window of 60–450 V, a start above 90 V, a 450 V open-circuit limit and a 120 A charge rate. It shows 3.8 from 3 reviews: one mentions packing and delivery, another says it did not meet their requirements without saying why, and a third could not discharge the battery below 70 percent. The title also says 220 V and 6.2 kW, while the bullets say 230 V AC and 6,200 W. The seller claims on-grid and off-grid modes, and the standards field is CE, with no G98 or G99 reference. At 6.2 kW it sits above the 3.68 kW single-phase G98 line if it were paralleled with the grid. A second AC output is said to stay on after the main output stops between 40 V and 46 V battery voltage, which is a listing claim, not a blackout test.
Pros
48 V hybrid with a 60–450 V window and a 120 A MPPT claim
Dual AC outputs are described, and a 2-year warranty is stated
Wi-Fi and BMS communication are claimed
6,200 W on the bullets matches the 6.2 kW title more closely than the smaller Y&H listings
Cons
3.8 from 3 reviews, including a stop at 70 percent discharge
On-grid wording with CE only, and 6.2 kW is above 3.68 kW on one phase
The title says 220 V as well as the 230 V bullets
One reviewer said it did not meet their requirements
Best for: A 48 V off-grid bank whose open-circuit voltage stays at or under 450 V, if you treat the on-grid sentence as unproven.
Less suitable: A grid-parallel house, a plug-in socket, or a battery you need to discharge below the 70 percent point one reviewer hit.
The Y&H NMS-1000-12 is a 12 V hybrid at £159.99, with a stated PV window of 20–150 V, a 150 V open-circuit limit, a start above 30 V and a 40 A charge rate, and the bullets cap the array at 600 W. The title and VA field say 1,000 W, the output-power field says 600 W, and the wattage field says 2,000 W, with a 2,000 W peak also printed. It shows 3.1 from 4 reviews, and one of those four is a colouring book, so it is not about this inverter. The only relevant UK review says the unit keeps switching off after about two minutes. Solar-only, mains-first and combined charging modes are listed, and there is an LCD. No plug type is stated, and the standards field is CE. Three power figures and a two-minute shutdown are the record, on a sample that is not even four inverter reviews.
Pros
12 V hybrid with a printed 20–150 V window and a 40 A MPPT claim
Solar and mains charging modes are named on one unit
An LCD and three LED indicators are stated
£159.99 is the lowest hybrid price in this set
Cons
The title says 1,000 W, the output-power field says 600 W, and the wattage field says 2,000 W
3.1 from 4, including a colouring-book review
The relevant UK review says it switches off after about two minutes
No plug type is stated, and the standards field is CE only
Best for: A small 12 V system only after you decide which of the three wattage figures you will plan around, and you accept the shutdown report.
Less suitable: A daily household load, or anyone who needs more than one relevant review.
The SPORTARC title says 3,000 W pure sine, 24 V to 220 V, at £68.29, and the item weight is 700 g, with a second dimension line of 21 × 3 × 6 cm beside 24 × 14 × 7 cm. It shows 2.7 from 6 reviews. UK texts say it trips at about 250 W, will not run a 900 W microwave, and is not 3,000 W. One short UK review says so far so good and also says the positive and negative leads were missing. A Belgium review in the saved listing, which is not a UK test, puts a ceiling near 600 W. The bullets claim both 12 V and 24 V, and the output fitment is 220 V rather than a stated 230 V UK output. There is no MPPT window, only the word solar in the title. The low price does not rescue a wattage the UK reviews contradict.
Pros
£68.29 is the lowest shelf price in this set
An LED indicator is stated
One UK reviewer had not found a fault yet, aside from missing leads
Cons
UK reviews say it trips around 250 W and will not run a 900 W microwave
3,000 W is claimed at about 700 g
12 V and 24 V are both claimed, and the output line is 220 V
Leads were missing for one buyer, and no PV window is stated
Best for: Only a very small load if you ignore the title watts and plan for a trip near 250 W.
Less suitable: A microwave, a bank you expect to support 3,000 W, or any solar array.
The BATENORY listing is an 800 W dual-MPPT micro inverter at £129.99 and 3 kg, with an MPPT window of 25–55 V, a 60 V maximum input, and a stated maximum AC current of 3.47 A at 230 V. The box includes a 5 m AC cable, and the plug format is not named. Bullets claim UKCA, G98, IP67 and a 10-year warranty, and the saved listing contains no type-test number and no customer-review line. The colour field is the German word Schwarz. The manufacturer is given as Astro Energy, and the model field simply says 800W. A fanless aluminium housing and a range of −40 °C to 65 °C are seller claims. With no UK review text, the specification is the whole of the evidence, and a G98 sentence is not an ENA register entry.
Pros
Dual MPPT, 25–55 V, 800 W, with a 5 m AC cable at £129.99
Maximum AC current is stated at 3.47 A
IP67 and a 10-year warranty are printed on the listing
Solarman is the named app
Cons
No star line and no review text
UKCA and G98 are bullets, with no type-test number in the file
The plug on the 5 m cable is not named
The colour field reads Schwarz
Best for: Comparing an 800 W dual-input micro on the printed window, if you will verify any register entry before it touches a socket.
Less suitable: You want UK reviewers to have described this ASIN, or you need the plug type confirmed on the listing.
The PioMue title lists 1,200 W, 1,400 W, 1,600 W and 1,800 W on one micro inverter at £164.22, and the item weight is 1 kg with a package size of 10 × 10 × 10 cm. There is no customer-review line and no review text. MPPT is claimed, and no panel voltage window is stated. Output is described as automatic 120/230 V, which is a mismatch risk on a UK 230 V circuit, and there is no G98 reference. The material field says Synthetic while the bullets also claim a waterproof aluminium casing, and the weather line says IP65. SPWM is named, which is a control method rather than a waveform. First listed on 11 October 2025, it is a grid-tie claim with four wattages and no UK evidence behind it.
Pros
IP65 is claimed, and remote monitoring is mentioned
Input and output are described as electrically isolated
The shelf price is £164.22 if the box matches one of the title wattages
Cons
Four continuous wattages in one title, at about 1 kg
No star line and no voltage window
Automatic 120/230 V is stated
The material field says Synthetic against an aluminium-casing claim
Best for: Only a buyer who first gets the seller to state one wattage, one output voltage and a panel window.
Less suitable: Any balcony or roof where you need a single output figure and a UK review.
The title lists 1200 W, 1400 W, 1600 W and 1800 W. There is no single spec-table wattage.
Is there a UK review score?
The saved listing has no customer-review line.
Will it only output 230 V?
The bullets claim automatic 120/230 V detection. A UK-only 230 V output is not stated on its own.
How we compared
Twelve amazon.co.uk solar-inverter listings were scored from shelf prices captured on 19 October 2026. Notes use those listing lines and the UK review themes stored with them. This is not a lab test. A G98 bullet, a UKCA line, a CE field or an on-grid sentence is a listing claim. None of these 12 listings is treated as an ENA type-test entry, an MCS install, or a unit that will be paid the Smart Export Guarantee or the Feed-in Tariff.
1
Amazon evidence
20%
The amazon.co.uk star rating is divided by 5, then multiplied by 20 and by a count factor. The factor is 0.85 at 100 reviews or more, 0.45 from 8 to 29, and 0.25 at 7 or fewer. No review line scores 0. Half values round up to the next integer.
2
Listing fit
40%
A class that matches the job, a PV window or an honest statement that there is no solar input, a continuous wattage the fields agree on, and a UK connection the listing names. A second wattage, a 220 V-only fitment, 120 V auto-detect, four wattages in one title, or a G98 sentence with no reference number, lower this part. Battery-only units are capped because this category is a solar inverter.
3
Review outcome
25%
UK themes about the unit that arrived: whether it ran, whether it died, and whether the watts matched the title. A star line with no text, or texts that describe a different wattage, cannot take the full share. A Germany or Belgium review is not used as UK opinion.
4
Value
15%
Shelf price against the job the listing actually supports. The lowest price does not win when UK reviews say the unit trips near a much smaller load. The dearest battery inverter does not win while its reviews describe other models.

Solar inverter buying guide
Start with the class, then the grid role, then whether the PV window, the continuous watts and the UK connection agree. Price comes after those three. The notes below follow that order for these 12 amazon.co.uk listings, checked on 19 October 2026. None of the scores is a lab test.
What is a solar inverter?
A solar inverter on amazon.co.uk is not one product. The same search mixes a grid-tied micro, a hybrid with an MPPT charger, and a battery inverter that only turns 12 V, 24 V or 48 V into about 230 V AC. Buyers include balcony occupants, off-grid and motorhome users, and people comparing a cheap hybrid with an installer-brand unit. A battery inverter does not replace an MPPT.
Best for
A balcony or flat occupant in Great Britain who will check the lease, the socket and the network-operator notification
An off-grid or vehicle owner with a 12 V, 24 V or 48 V bank who needs pure sine and an honest current
A household that wants night-time loads from a hybrid and will treat an on-grid bullet as unproven
Not ideal for
Anyone treating a G98 or UKCA bullet as an ENA type-test entry
A buyer who expects a grid-tied micro to run the house in a power cut
Anyone who ranks a battery inverter against a micro by review count alone
Mistakes to avoid
1
Ranking every class by review count
A large star sample on a battery inverter does not describe an MPPT window. Compare micros with micros, hybrids with hybrids, and battery inverters with battery inverters. Panel watts are not the G98 rating. Use the inverter’s continuous AC output.
2
Trusting a G98 bullet or a title wattage
A G98 or UKCA sentence with no reference number is not an ENA type-test entry. Where UK reviews describe a much smaller load than the title, plan for the load the reviews describe. Modified sine is a poor match for CPAP, active power-factor correction and many motors.
3
Expecting export pay or blackout cover
The Smart Export Guarantee for solar PV at or under 50 kW normally needs a certified install, often MCS, and half-hourly export metering. The Feed-in Tariff is closed to new applicants. A grid-tied micro shuts down in an outage. Island mode must not run in parallel with the network.
What to weigh up
Class, grid role and electrical match
High
Decide micro, hybrid or battery-only before you compare prices. A micro takes panel DC to grid AC. A hybrid adds a PV charger to a battery inverter. A battery inverter has no MPPT, so it does not replace a charge controller.
Off-grid use, a plug-in micro inside the Great Britain 800 W rules, and a parallel connection under G98 or G99 are different jobs. G98 is fit-and-notify up to 16 A per phase, 3.68 kW at 230 V, with notification within 28 days and shutdown in an outage.
Waveform, continuous watts and evidence
High
Pure sine is the waveform to look for if you run electronics. Modified sine is a poor match for CPAP, active power-factor correction and many motors. A 12 V multi-kilowatt load is hundreds of amps before losses, so the battery cables are part of the job.
Read the continuous AC figure the fields agree on. A title that lists several wattages, or a wattage field that disagrees with the title, is a conflict, not a bonus.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
🏠
A daytime balcony or garden office
You want panel DC into a UK socket in daylight, and you will check the lease and notify the network operator. The Solarsys 800 W kit is about £139.99, with a UK 13 A lead and 4.1 from 12 reviews. It does not run the house in a power cut, and the file has no G98 reference number.
You need pure sine and UK sockets from a leisure bank, and the panels already have their own charge controller. The Renogy 1,000 W is about £113.99, with 4.4 from 163 reviews. The listing states no MPPT window.
You want a hybrid that can charge from a panel string and invert after dark, and you will keep it off-grid unless a competent person says otherwise. The Y&H 3,200 W is about £255.99, with a 55–450 V window and 4.4 from 8 reviews. The Wi-Fi dongle is extra, and the standards field is CE.
A solar inverter turns panel direct current into alternating current. On amazon.co.uk the same search mixes three classes: a grid-tied micro, a hybrid with an MPPT charger, and a battery inverter that only turns 12 V, 24 V or 48 V into about 230 V AC. A battery inverter does not replace an MPPT. Match class, PV window, continuous AC watts, waveform and the UK connection before you compare prices.
Which solar inverter is the top pick in this set?
The top pick is the Solarsys 800 W micro inverter kit, about £139.99, with 4.1 from 12 amazon.co.uk reviews and a score of 65. The listing includes dual MPPT and a 3 m lead to a UK 13 A plug. The sample includes an early failure, a low yield comparison and no G98 reference number. The score is not a lab test, and the kit is not treated as an ENA type-test entry.
Which solar inverter is best value?
The best value is the elejoy EGMI-500, about £99.99, with 4.8 from 7 reviews and a score of 59. It is the lowest-priced micro in this set with a stated MPPT window of 22–50 V and a UK rating of at least 4.5 from at least five reviews. No 13 A plug is named in the box, and the standards field is CE, with no G98 string. Seven reviews is a small sample.
Can I plug a solar inverter into a UK socket?
Great Britain allowed compliant plug-in solar from 27 August 2026, at 800 W registered capacity and one unit per installation, and you still notify the distribution network operator. Northern Ireland still needs its own change. The listing has to name a BS 1363 connection, not only a G98 bullet. A new circuit or a mains-parallel connection is work for a competent person. A grid-tied micro still shuts down in an outage.
Does a G98 bullet mean the inverter is approved?
No. G98 is the fit-and-notify route up to 16 A per phase, 3.68 kW at 230 V, with notification within 28 days and shutdown in an outage. Above that, G99 applies first. A sentence that says G98 or UKCA, with no type-test reference, is not an ENA register entry. This comparison does not treat any of the 12 listings as MCS-certified, or as a unit that will be paid the Smart Export Guarantee or the Feed-in Tariff.
Will a grid-tied micro run the house in a power cut?
No. A grid-tied micro is meant to shut down in an outage so it does not energise the network. Island mode must not run in parallel with the mains. Night-time loads need a battery and a hybrid or a separate inverter, and an on-grid bullet stays unproven until that model is on the type-test register. DC from the panels stays live in daylight even when the AC side is off.
When should I call a competent person?
Call a competent person for a new circuit, any connection in parallel with the mains, high-current battery cables, and a flat or a timber balcony. BS 7671 still applies, and BS EN 62109 covers inverter safety without setting the grid code. If you cannot confirm the PV window, the continuous watts and the UK connection, do not energise the unit. Panel-DC micros are lined up in the micro inverter comparison.
Our verdict
In this set of 12 amazon.co.uk listings, the top pick is the Solarsys 800 W micro inverter kit at about £139.99, with 4.1 from 12 reviews and a score of 65. It has a UK 13 A lead and dual MPPT, and the largest review sample among the micros here. The best value is the elejoy EGMI-500 at about £99.99, with 4.8 from 7 reviews and a score of 59: the lowest-priced micro with a stated MPPT window and a UK rating of at least 4.5 from at least five reviews. Neither score is a lab test. A G98 bullet is not an ENA type-test entry, and none of these listings is treated as an MCS install or as a unit that will be paid the Smart Export Guarantee.
Lowest-priced micro with a stated 22–50 V MPPT window, about £99.99, 4.8 from 7 reviews. Score 59. No 13 A plug is named, and the standards field is CE only.
