The best 800 watt inverters, compared.
Top pick: Yinleader 800W car inverter – Highest score in this set: about £31.18, 4.2 from six ratings, score 84. A 12 V modified-sine inverter, not a solar unit. Best value: Solarsys 800W micro inverter kit – Best value among listings that name a UK plug and have UK reviews: about £139.99, 4.1 from 12, score 82. Updated 22.10.2026.
An 800 watt inverter on amazon.co.uk is one of two products. A solar micro inverter turns panel DC into about 230 V AC so it can run in parallel with the mains. A portable inverter turns 12 V battery DC into AC for a car or van. It is modified sine, with a UK socket, and it is not a grid-tie inverter. A UK plug, or a bullet that says, does not prove a model is on the Energy Association type-test register. The order of the checks is in the [800 watt inverter buying guide](/hub/electrical-equipment/800-watt-inverter/sub/800-watt-inverter-buying-guide). A grid-tie micro inverter takes panel DC and makes mains-frequency AC that synchronises with the grid and must stop if the mains fail. A battery inverter takes 12 V DC and feeds appliances that are not the grid. A wider look at panel-side units is on the [micro inverter](/hub/electrical-equipment/micro-inverter) comparison.

Question 1 of 2
What are you powering?
The Yinleader is a 12 V battery inverter, not a solar micro inverter: 800 W continuous, 1,600 W peak, modified sine, one UK AC socket, and dual USB, at £31.18. The box includes a cigarette-lighter lead, and the case is about 220 × 97 × 57 mm at 650 g. The star line is 4.2 from six ratings, with only two United Kingdom review texts on the listing. Those texts praise it for small appliances and call the price right for a budget unit, and they also say it is sensitive to a low battery. One of the two texts says the output was too choppy for laptop chargers, which sits against a highlight that names laptops. A bullet prints 230 V while the attribute field prints 220 V AC. A lighter socket is typically fused around 10 A, so the lead in the box is not a route to the full 800 W.
Pros
Cons
Best for: You want AC for a simple load from a 12 V battery, and you will connect it at the battery rather than through the lighter socket at full rating.
Less suitable: You want pure sine for a laptop charger, or a solar micro inverter on a household socket.
Specifications
Common questions
Is a cigarette-lighter lead included?
Yes. The box list includes a cigarette-lighter power cable. The continuous rating on the listing is still 800 W.
Is the AC output pure sine?
No. The listing says modified sine wave. One of the two UK review texts says the output was too choppy for laptop chargers.
Which output voltage is printed?
A bullet says 230 V and the attribute field says 220 V AC. Both figures are on the listing, so the page keeps both.
The Solarsys kit is the only listing in this set whose title states a 3 m lead from a BC01 connector to a UK 13 A plug, with pure sine output at 230 V. It is built for two panels of 300–550 W on dual MPPT, claims IP67, and weighs 3.6 kg, at £139.99. Across 12 United Kingdom reviews the line is 4.1. One buyer with two 460 W panels reported about 730–750 W at midday in August, and several describe a straightforward MC4 and plug setup on 2.4 GHz Wi-Fi. Two reviewers said they could not confirm ENA or government approval and kept the unit off the grid. One unit died after 22 days on two 400 W panels, and one comparison put output at about half an Enphase IQ8HC in the same conditions. The warranty field is one year, and one review says the hardware is an Elecway VN2T sold under the Solarsys name.
Pros
Cons
Best for: You want the only solar listing in this set that names a UK 13 A plug, and you will still check the type-test register yourself.
Less suitable: You need a confirmed G98 device reference before you connect, or a warranty longer than one year on the listing.
Specifications
Common questions
Does this kit include a UK plug?
Yes. The title states a 3 m AC cable from a BC01 female connector to a UK 13 A plug.
Which panels does the listing name?
Two panels rated from 300 W to 550 W each, on two MPPT inputs. Dimensions of the inverter itself are not on the listing.
Do the UK reviews confirm grid approval?
Two United Kingdom reviews say the writer could not confirm ENA or government approval and used the unit off the grid. The listing itself claims European grid-connection standards.
The NEP listing is an 800 W solar inverter at £92, with pure sine, IP67, and Wi-Fi or PLC monitoring claimed, plus a 12-year warranty line. The star line is 3.7 from 26. The review texts on the listing are from Poland, Germany, Italy, and the Netherlands, so they are not United Kingdom owners. Those texts mention generation in sun and a solid build, and they also describe difficult Wi-Fi pairing, a seller who did not answer a defect complaint, a missing mains cable, and panel voltage that was too low for one buyer. The output-voltage attribute says 60 V DC, which conflicts with an AC inverter description, so a 230 V figure is not taken from this page. The box is one inverter and one power cable, and the plug standard is not stated. Brand is filed as VKY and the manufacturer as SHP.
Pros
Cons
Best for: You are comparing shelf prices and will not buy until AC voltage and the plug are confirmed in writing.
Less suitable: You need a UK 13 A plug in the title, or review texts from the United Kingdom.
Specifications
Common questions
What AC voltage does the listing state?
The output-voltage attribute says 60 V DC. That conflicts with an inverter description, so a 230 V figure is not shown.
Does the listing claim a UK plug?
No. The box is one inverter and one power cable. The plug standard is not stated.
Are the written reviews from the United Kingdom?
The star line is 3.7 from 26. The review texts on the listing are from Poland, Germany, Italy, and the Netherlands.
The BATENORY listing states 800 W at 230 V and 50 Hz, with dual MPPT from 25–55 V and a maximum input of 60 V. The box line is a 5 m AC cable, and the page does not name the plug, so you cannot tell whether a BS 1363 13 A plug is fitted. Bullets claim UKCA and G98, a 10-year warranty, and a fanless housing rated IP67, at £129.99. There is no amazon.co.uk star line and no review text on the listing, so those certification claims are not backed by buyers on this page. Waveform is not stated either. It sits close in price to the Solarsys kit, which does name a UK plug and has 12 UK reviews. The colour field on the listing reads Schwarz.
Pros
Cons
Best for: You already have a plug plan and a distribution-network route, and you want the 25–55 V window written on the page.
Less suitable: You want UK buyer reports, or a title that names a 13 A plug.
Specifications
Common questions
Does the listing include a UK 13 A plug?
The listing states a 5 m AC cable. It does not name the plug type, so that detail is n/a.
Is outdoor balcony use claimed?
The listing claims IP67 and describes the inverter for balcony and DIY solar use. The colour field reads Schwarz.
What solar input does the listing give?
MPPT voltage 25–55 V, maximum input 60 V, maximum input current 2 x 13.5 A, and rated output 800 W at 230 V.
Four 800 watt inverters on amazon.co.uk were scored from the listing and the review notes, not from a lab test. Prices are the GBP shelf prices on those amazon.co.uk listings. A missing star line keeps the score at 0, which is why BATENORY stays at 0 despite a full spec list. An output voltage that conflicts with an AC inverter, the 60 V DC attribute on NEP, is a clear deduction. Review texts from outside the United Kingdom are not treated as UK owner opinion. Yinleader is 84, Solarsys is 82, NEP is 74 and BATENORY is 0. Warranty length is noted and does not outweigh a missing plug or a missing star line. The weights below are the relative place of those checks.
Star line and rating count
35%The amazon.co.uk star average, and how many ratings sit behind it, is the start of the score. No star line and no review text keeps the score at 0.
United Kingdom review texts
20%Written reviews count as UK owner opinion only when they are from the United Kingdom. A star line from other countries is kept, and it is not treated as a UK sample.
Watts, waveform and UK connection
25%The listing needs continuous watts, a waveform and a UK mains connection you can read. A 60 V DC output attribute conflicts with an AC inverter and is a clear deduction.
Price against that evidence
15%Price is judged against the plug, the voltage and the review sample. A lower price does not win the value award when AC voltage or the plug is not stated.
Warranty as written
5%Warranty length is noted from the listing. It does not outweigh a missing plug or a missing star line.
Start with the class of inverter, then continuous watts rather than peak, then waveform, then whether that model may connect to the mains. Price comes after those checks. The notes below follow that order for these four amazon.co.uk listings from October 2026. None of the scores is a lab test.
An 800 watt inverter on amazon.co.uk is sold as two different machines. A grid-tie micro inverter takes panel DC and makes mains-frequency AC that synchronises with the grid and must stop if the mains fail. A battery inverter takes 12 V DC and feeds appliances that are not the grid. In this set, Yinleader is the only battery inverter. BATENORY, Solarsys and NEP are sold as solar micro inverters. They are not substitutes.
Yinleader prints 800 W continuous and 1,600 W peak. The peak is not the load you can run. A kettle or a 2 kW heater is outside this category.
Yinleader is a 12 V battery inverter with a UK socket. It is not a grid-tie micro inverter. Do not use it as generation on a household socket.
Solarsys names a UK 13 A plug. BATENORY bullets claim G98. Neither figure is a check of the Energy Networks Association type-test register. Two Solarsys reviewers did not grid-connect.
Class comes first. A grid-tie micro inverter synchronises with the mains and must stop if the mains fail. A battery inverter feeds appliances from 12 V and is not generation. Yinleader is the only battery inverter in this set. BATENORY, Solarsys and NEP are sold as solar units. Continuous output on every listing here is 800 W. Yinleader also prints 1,600 W peak. Do not size a load to that peak. Waveform splits the same way as class.
For solar onto the mains, read SI 2026/848 and look the model up on the ENA G98 register. A UK 13 A plug or a G98 bullet is not that check. This research did not confirm the three solar ASINs on the register. Regulation 3 of SI 2026/848 does not extend to Northern Ireland. One 800 W unit is about 3.5 A. Existing generation on the same phase counts toward the 16 A G98 limit, and National Grid Electricity Distribution asks for notification within 28 days. Panel match is only for the solar units.
Three typical situations, each with a recommendation from this comparison.
You want a few hundred watts of AC in a car or van, and you will connect at the battery rather than pull 800 W through the lighter socket. The Yinleader is about £31.18. It is modified sine, and it is not a solar micro inverter.
You want panel AC on a household socket, and you will check consent and the type-test register yourself. Solarsys is about £139.99 and is the only title here that names a UK 13 A plug. Two UK reviewers did not grid-connect.
You already have a plug plan and a distribution-network route, and you want the 25–55 V window on the page. BATENORY is about £129.99. There is no amazon.co.uk star line, and the plug type is not stated.
In this set of four amazon.co.uk listings, the top pick is the Yinleader 800W car inverter. It is about £31.18, with 4.2 from six ratings, and the score is 84. It is a 12 V modified-sine inverter with a UK socket, not a solar micro inverter, and only two review texts are from the United Kingdom. The best value is the Solarsys 800W micro inverter kit at about £139.99, with 4.1 from 12 United Kingdom reviews, because the title names a UK 13 A plug. Its score is 82. NEP at about £92.00 scores 74: the output-voltage attribute says 60 V DC, and the written reviews are not from the United Kingdom. BATENORY at about £129.99 scores 0 because there is no star line. None of these scores is a lab test, and none of the solar models was confirmed on the ENA type-test register.
