Four panels on one microinverter
You already have four panels inside a 16–60 V window and a 65 V maximum, and you will buy an S-series DTU separately. The HMS-1800 listing is about £429.99 and rates 1,800 VA.
The best Hoymiles inverters, compared.
Top pick: HMS-1800 four-input – Only kept row with a consistent four-input spec and a reviews line: about £429.99, 3.3 from 4, score 66 from that star line, not a lab test. Best value: HM-700 balcony package – Same about £379.99 as the HMS-1000 listing, and the box adds balcony brackets and a 3 m cable. Updated 22.10.2026.
A Hoymiles inverter here is a photovoltaic microinverter that turns panel DC into AC for a grid-tied UK installation. You match a small array or a balcony set to the model suffix, the panel count, the AC connector and the gateway. Plug-in rules apply only if the unit is an 800 W AC microgenerator with a BS 1363 plug. None of these three is shown as type-tested or as legal for a UK socket. The checks are in the [Hoymiles inverter buying guide](/hub/electrical-equipment/hoymiles-inverter/sub/hoymiles-inverter-buying-guide). Is the later single-phase family on these shelves: the listing and the four-input listing. A model with the radio inside the inverter is a third pattern, and none of these rows clearly is one. A title that says Hoymiles is not enough when the standards line is UL 1741 and rather than a UK type-test reference. The datasheet for to describes 230 V, 50 Hz, IP67, fanless units wi-1G monitoring. Two of the listings print UL and text instead.

Question 1 of 2
How many panels are you connecting?
The Solarsys HMS-1800 listing at £429.99 is the four-input row, rated 1,800 VA, with an MPPT window of 16–60 V, a 65 V maximum and 4 × 16 A. The saved amazon.co.uk line is 3.3 from 4 reviews, and those texts are from France and Spain, including one report of output falling once four 410 W panels pushed past about 1,200 W. That is a single account, not a failure rate, and 1,800 VA on the title is not 1,800 W of British generation. The pack is the microinverter alone: a DTU-WLite-S or DTU-Pro-S is required for S-Miles Cloud and is not in the box, and the listing does not name a BS 1363 plug. A France review says the AC output is rectangular while the recommended cable is round. The standards line prints UL 1741, IEEE 1547 and NEC rapid shutdown, with no G98 type-test number. It is the top pick here only because it is the only kept row with a consistent four-input spec and a review line, and the score is that star line scaled to 100, not a lab test.
Pros
Cons
Best for: You already have four panels inside the 16–60 V window and 65 V maximum, and you will buy an S-series DTU separately.
Less suitable: You need a BS 1363 plug, a G98 number on the listing, or a two-panel unit under an 800 W socket cap.
Specifications
Common questions
Does this HMS-1800 listing include a DTU?
No. The bullets say a DTU-WLite-S or DTU-Pro-S is required for S-Miles Cloud, and the pack line is one item.
Does the listing name a UK 13 A plug?
No. It does not name a BS 1363 plug. A France review says the AC output is rectangular and the recommended cable is round.
Which standards does the listing print?
UL 1741, IEEE 1547, UL 1741 SA, CA Rule 21, CSA C22.2 No. 107.1-16, FCC, and NEC/CEC rapid shutdown. It does not print a G98 type-test number.
The HM-700 balcony package is £379.99, the same shelf price as the HMS-1000 listing, and the box adds balcony brackets and a 3 m AC cable, with no solar panel. The inverter bullet says an AC maximum of 700 W and two panels of 280–470 Wp, while the MPP line is printed as 16–20 V DC, narrower than the 16–60 V window on the Europe HM sheet. The cable is a Betteri BC01 lead to an EU embedded plug with VDE certification, not a BS 1363 plug. Standards named are VFR, VDE-0126-1-1, VDE-AR-N 4105 and EN 50549-1, with no G98 number and no customer-reviews line. The warranty field says lifetime against manufacturer defects and a bullet also says 25 years, so those two lines should not be merged, and the manufacturer field says Elfcam while the brand line says Solarsys. It is the best value here only because the same £379.99 includes brackets and a lead the HMS-1000 row does not. That value goes if you needed a UK 13 A plug or a panel in the carton.
Pros
Cons
Best for: You want the older HM-700 plus balcony brackets at £379.99, and you will not adapt the EU plug.
Less suitable: You need a BS 1363 socket kit, a panel in the box, or an HMS unit with an S-series gateway.
Specifications
Common questions
Is a solar panel included?
No. The title says without a solar panel. The pack is the HM-700, balcony brackets, and a 3 m AC cable.
Is the plug a UK 13 A plug?
No. The cable is described with a Betteri BC01 female connector and an EU embedded plug with VDE certification.
What MPP range does the listing print?
16–20 V DC, and CEC efficiency as ninety-seven percent. A separate bracket line mentions 60-cell and 72-cell panels from 200 W to 600 W.
The Solarsys HMS-1000 listing is £379.99, and the title says 1,000 W for two panels, with an MPPT window of 16–60 V, a 65 V maximum, 2 × 16 A and a rated 1,000 VA. One bullet on the same page says 800 W and up to one panel, and a voltage field says 12 V DC, so those figures should not be averaged into one spec. The saved listing has no customer-reviews line, no BS 1363 plug, and no DTU in the box even though the bullets require a DTU-WLite-S or DTU-Pro-S for S-Miles Cloud. The standards line repeats UL 1741, IEEE 1547 and NEC rapid shutdown, with no G98 number. A lifetime-against-defects field is the listing’s wording, not a confirmed Hoymiles factory term. One bullet also says “hm series”, which does not turn this HMS title into the older HM family. Leave it out of the basket until the seller confirms inputs, wattage and voltage against the label.
Pros
Cons
Best for: You are checking a two-panel HMS title and will match the label before you pay, rather than treating the bullets as settled.
Less suitable: You need a listing whose wattage, panel count and voltage already agree, or any UK review sample.
Specifications
Common questions
Is the saved HMS-1000 listing consistent?
No. The title says 1000 W and two panels. One bullet says 800 W and up to one panel. A voltage field says 12 V DC while the max input is 65 V.
Does this listing include a DTU or a UK plug?
Neither is listed. The bullets say a DTU-WLite-S or DTU-Pro-S is required, and they do not name a BS 1363 plug.
How many amazon.co.uk reviews are on the saved page?
The saved listing has no customer-reviews line, so there is no UK review count to quote.
Three Hoymiles inverter listings on amazon.co.uk were kept. There is no lab test. The only published score is the HMS-1800 star line scaled to 100, which is 3.3 from 4, set to 66. The other two saved pages have no customer-reviews line, so their score stays 0. A title that says Hoymiles does not add points when the standards line is UL and NEC, or when the bullets disagree with the title. The top pick is the only kept row with a consistent four-input spec and a review line. The best value is the £379.99 HM-700 package because the box adds balcony brackets and a 3 m cable. The weights below are the order of the buying checks, not a lab score.
Model suffix and standards line
25%Read HMS-1800, HMS-1000 or HM-700, and the -2T or -4T suffix if it is printed. UL 1741 and NEC text is not treated as a G98 type-test number.
Inputs and the DC window
25%Panel count, MPPT window, maximum DC voltage and input current have to agree on the listing. Conflicting wattage or voltage bullets are not averaged.
AC connector and UK plug
20%A named BS 1363 plug is the UK socket check. An unnamed connector, or a Betteri BC01 lead to an EU plug, does not pass that check.
Monitoring gateway
15%HMS listings that require a DTU-WLite-S or DTU-Pro-S for S-Miles Cloud lose nothing for saying so, and they do not gain points when the DTU is absent from the box.
Connection paperwork
15%G98 or G99, and the ENA type-test register, sit beside the listing. An Amazon page is not scored as a completed DNO notification or as an export-tariff application.
Start with the exact suffix, then the DC window, then the AC connector and the gateway. Price comes after those checks. The notes below follow that order for three amazon.co.uk listings. None of the scores is a lab test, and none of the listings is treated as a finished G98 notification.
A Hoymiles inverter in this comparison is a photovoltaic microinverter. It turns panel DC into AC for a grid-tied UK installation. You are matching a small array or a balcony set to panel count, the AC connector and a gateway. HMS is the later single-phase family on these shelves: the HMS-1000 listing and the HMS-1800 four-input listing. HM is the older family, kept here as the HM-700 balcony package. HMT is three-phase and is not in this set.

A 12 V inverter, a DTU, or a lead is not the microinverter. The HMS-1000 page has a 12 V field beside a 65 V maximum. Match the suffix on the label before you pay.
The HM-700 cable is Betteri BC01 to an EU embedded plug. The HMS listings do not name that connector. Do not join the families, and do not cut a plug to force a fit.
UL 1741, IEEE 1547 and NEC rapid shutdown on the HMS pages are not a G98 type-test number. The ENA form for some HMS-600W-2T to HMS-1000W-2T units does not prove these ASINs.
The model line is the first filter. HMS-1800 on this shelf is a four-input listing at 1,800 VA, MPPT 16–60 V, 65 V maximum and 4 × 16 A. HMS-1000 is titled as two panels and 1,000 VA, and one bullet also says 800 W and one panel, with a 12 V field beside 65 V. HM-700 is a 700 W package for two panels of 280–470 Wp, with MPP printed as 16–20 V DC. Use the label when those lines disagree. Do not turn 1,800 VA into a promise of 1,800 W in UK sun.
The HM-700 lead is Betteri BC01 to an EU plug. Neither HMS listing names a BS 1363 plug. Plug-in rules from 27 August 2026 are for an 800 W AC microgenerator on a fixed UK 13 A socket. They are not met by an unnamed connector or by an EU plug. Do not mix HM and HMS leads. Both HMS pages require a DTU-WLite-S or DTU-Pro-S for S-Miles Cloud and leave it out of the box. The HM-700 page does not name a DTU. G98 is the notification route up to 16 A per phase, within 28 days.
Three typical situations, each with a recommendation from this comparison.
You already have four panels inside a 16–60 V window and a 65 V maximum, and you will buy an S-series DTU separately. The HMS-1800 listing is about £429.99 and rates 1,800 VA.
You want the older HM-700 plus balcony brackets and a 3 m cable at about £379.99, and you will not adapt the EU plug. No solar panel is in the carton.
You are comparing the HMS-1000 title at about £379.99 and you will match the label before you pay. One bullet on that page does not agree with the title.
In this set of three amazon.co.uk listings, the top pick is the HMS-1800 four-input at about £429.99. It is the only kept row with a consistent four-input spec and a reviews line, 3.3 from 4, and the score is that star line scaled to 100, not a lab test. The best value is the HM-700 balcony package at about £379.99, because that price includes balcony brackets and a 3 m cable the HMS-1000 row does not. The HMS-1000 listing has no award: the title and a bullet disagree on wattage and panel count. None of these listings is treated here as G98 type-tested or as a UK 13 A plug-in kit.

HMS-1800 four-input
Only kept row with a consistent four-input spec and a reviews line: about £429.99, 3.3 from 4, score 66 from that star line, not a lab test.

HM-700 balcony package
Same about £379.99 as the HMS-1000 listing, and the box adds balcony brackets and a 3 m cable.
