What the manufacturer documents

• Victron's Quattro 120 V datasheet (3 kVA to 10 kVA, no version number printed; the file's own metadata is dated 2026-04-14) lists the 48/10000/140-100/100 120 V model at 10000 VA continuous at 25 C (77 F), with the footnote non-linear load, crest factor 3:1. In watts it lists 8000 W at 25 C (77 F), 6500 W at 40 C (104 F) and 4500 W at 65 C (150 F). It lists peak power of 20000 W without a duration, an output of 120 VAC plus or minus 2 percent at 60 Hz plus or minus 0.1 percent in inverter mode, and an inverter input voltage range of 38 to 66 V. We read the 10 kVA values from the last column of a table that our text extraction laid out unevenly. (victronenergy.com)
• Victron's MultiPlus-II 120 V datasheet (no version number printed on it) lists the 48/3000/35-50 model at 3000 VA continuous at 25 C (77 F) per unit (non-linear load, crest factor 3:1) and, in watts, 2400 W at 25 C (77 F), 2200 W at 40 C (104 F) and 1700 W at 65 C (150 F). It lists peak power of 5500 W without a duration, output of 120 VAC plus or minus 2 percent at 60 Hz plus or minus 0.1 percent, and a DC input voltage range of 38 to 66 V. (victronenergy.com)
• Victron's Quattro 120 V datasheet (3 kVA to 10 kVA, no version number printed; the file's own metadata is dated 2026-04-14) lists a maximum battery charge current of 140 A for the 48/10000/140-100/100 (its footnote says up to 25 C ambient), with charge voltages of 57.6 V absorption, 55.2 V float and 52.8 V storage mode. (victronenergy.com)
• Victron's MultiPlus-II 120 V datasheet (no version number printed on it) lists a maximum battery charge current of 35 A for the 48/3000/35-50 (its footnote says up to 25 C / 75 F ambient), with the same charge voltages of 57.6 V absorption, 55.2 V float and 52.8 V storage mode. (victronenergy.com)
• Victron's Quattro 120 V datasheet (3 kVA to 10 kVA, no version number printed; the file's own metadata is dated 2026-04-14) describes two AC inputs with an integrated transfer switch, each with an input voltage range of 90 to 140 VAC, input frequency of 55 to 65 Hz and power factor 1, and lists a maximum feed through current of 2 x 100 A for the 10 kVA model. It says the unit connects automatically to the active source and that, in a grid failure or when shore or generator power is disconnected, it takes over supply to the main output in less than 20 milliseconds. (victronenergy.com)
• Victron's MultiPlus-II 120 V datasheet (no version number printed on it) describes one AC input (90 to 140 VAC, 55 to 65 Hz) and lists a transfer switch rating of 50 A and a maximum AC input current of 50 A for the 48/3000/35-50. It says the unit takes over supply to the main output in less than 20 milliseconds. (victronenergy.com)
• Both datasheets describe two AC outputs. The main output is the one the unit keeps live from the battery, and the second output is live only when AC is present on an input (on the Quattro, on one of its two inputs). The Quattro datasheet lists an auxiliary output of 50 A for the 10 kVA model and the MultiPlus-II datasheet lists 32 A for the 48/3000, both noting that the auxiliary output switches off when no external AC source is available. (victronenergy.com)
• Victron's Quattro 120 V datasheet (3 kVA to 10 kVA, no version number printed; the file's own metadata is dated 2026-04-14) lists maximum efficiency of 96 percent for the 10 kVA model and zero load power of 60 W (40 W in AES mode and 15 W in Search mode), without stating battery voltage, temperature or other conditions for those figures. (victronenergy.com)
• Victron's MultiPlus-II 120 V datasheet (no version number printed on it) lists maximum efficiency of 95 percent for the 48/3000/35-50 and zero load power of 11 W (7 W in AES mode and 2 W in Search mode), without stating battery voltage, temperature or other conditions for those figures. (victronenergy.com)
• Victron's Quattro 120 V datasheet (3 kVA to 10 kVA, no version number printed; the file's own metadata is dated 2026-04-14) lists a common operating temperature of -40 to +65 C, humidity (non-condensing) up to 95 percent, an aluminium enclosure and protection category IP 21. For the 10 kVA model it lists a weight of 128 lb (58 kg) and dimensions of 572 x 488 x 344 mm (22.6 x 19.2 x 13.6 in), in the order height, width, depth. It lists the battery connection as four M8 bolts (two plus and two minus) and the AC connection as M6 bolts for the larger models. Its safety line lists UL 1741 for the 48 V 5 kVA and 10 kVA models only. The weight and size row is laid out unevenly in our text extraction, so we read the largest values as the 10 kVA model. (victronenergy.com)
• Victron's MultiPlus-II 120 V datasheet (no version number printed on it) lists an operating temperature range of -40 to +60 C (-40 to 140 F) with fan-assisted cooling, protection category IP22, a steel enclosure, a weight of 19 kg (42 lb) and, for the 48/3000 listed as UL1741 certified, dimensions in the order height, width, depth of 572 x 277 x 147 mm (22.5 x 10.9 x 5.8 in), with a footnote giving 536 x 277 x 147 mm for a model that is not UL1741 certified. It lists the battery connection as 2 M8 bolts. (victronenergy.com)
• Victron's Quattro 120 V datasheet (3 kVA to 10 kVA, no version number printed; the file's own metadata is dated 2026-04-14) says two units can be configured for split phase and three units for three phase output, and that up to 4 sets of three units can be connected in parallel, quoted as 120 kVA of inverter power and more than 1600 A of charging capacity (the printed text gives the power figure in a garbled form that includes 96W, which we could not resolve). It does not state in the text we extracted a count for plain single phase parallel connection of the 120 V models. (victronenergy.com)
• Victron's MultiPlus-II 120 V datasheet (no version number printed on it) says up to 6 units can operate in parallel, that two units of the same model can be connected for a 240 V split phase output, and that three units of the same model can be configured for three phase output, with up to 6 sets of three units in parallel. (victronenergy.com)
• EG4's WallMount Indoor 280Ah battery specification sheet, version 1.1.8, lists a maximum continuous discharging current of 140 A and 200 A maximum continuous for 30 minutes. Its changelog says version 1.1.5 modified the maximum continuous charging and discharging current from 200 A to 140 A and version 1.1.7 added the 200 A for 30 minutes discharge value. Which sheet revision applies to the battery in our videos is not recorded. (eg4electronics.com)

What happened to us

• We set up a Victron Quattro 48 V 10 kVA (the video shows it as a 120 V, single phase unit) with an EG4 WallMount Indoor battery, a Cerbo GX linked by a VE.Bus cable and a load center fed from the Quattro. The owner has since confirmed it is the 48 V 10 kVA 120 V model; the exact model label, firmware, serial and UL1741 status are not recorded. On camera the heater on the output was drawing about 1,400 W on the Cerbo GX screen, and we said that was low for a unit rated for about 8,000 W continuous. We also said the three fans were fairly quiet and the transformer gave a low frequency hum. (video)
• In the setup video we read out the front-panel and datasheet specifications for the 10 kVA model in our own words (8,000 W continuous at 25 C, 6,500 W at 40 C, 4,500 W at 65 C, 20,000 W peak, 96 percent maximum efficiency, idle consumption about 60 W, 40 W in AES mode and 15 W in Search mode, weight 128 lb). These were read from the documents and are not measurements. (video)
• In our first load test the Quattro was fed from the EG4 WallMount Indoor battery and the loads were induction cooktops (each aimed at roughly 1,500 W), an electric kettle, a resistive heater, a Makita air compressor, two shop vacuums, a small fan and a water boiler. Readings were spoken from the Cerbo GX screen and are approximate: about 6,000 W, then 7,200 to 7,300 W, then about 8,000 W which we called 8,000 W continuous, and about 180 A out of the battery. The duration at each level is not stated. (video)
• In the same video, after a restart with a different pot on an induction cooktop, the reading reached about 9,000 W when the compressor started and settled to about 8,000 W, and we said that matched the rated spec in a warm room (the owner later gave about 78 F as the garage temperature, see the caveats). When the shop vacuums were added the reading reached about 9,500 to 9,700 W and the Quattro showed an overload and a low battery light, and the Cerbo GX showed an alarm for high discharge current. On camera we said we believed the cause was the battery, which we said from memory was rated for about 200 A continuous (see the EG4 sheet under What the manufacturer documents; the sheet revision applicable to our unit is not recorded), and that we should revisit the test with more battery capacity. The owner has since said that the shutdown at about 9,500 W was the Quattro's overload. Both statements are recorded here and we do not say either is wrong. Afterwards the loads ran again at about 7,000 to 7,600 W with the battery reading about 154 to 176 A. We also said a 120 V flux core welder and starting the compressor and shop vacuums worked without an issue. We did not time any of these runs. (video)
• In the second video we ran the 120 V Quattro through a Victron auto transformer, described on camera as the higher amperage of two versions (the owner has since said it was the higher-amperage, US version), which we described as taking 120 V single phase and creating 240 V split phase with a neutral. We said its neutral current limit was about 20 A continuous and not more than 30 minutes, and later said 32 A continuous, and we were not sure of the figure; those are spoken guesses. The auto transformer model number is not recorded. The loads were an EG4 chargeverter wired for 240 V and charging batteries, induction cooktops, an electric kettle and a resistive heater, on a load center wired for the test. (video)
• In that test the chargeverter display reading was about 54.4 V and about 94.1 A, which we described as charging. Separately, the Cerbo GX screen showed about 5,700 W (we also said 5,600 W) on the load when the chargeverter breaker was the only load, and a clamp meter on one leg read about 24 to 25 A. We spoke an estimate of about 5,700 W for the charger; that was our spoken arithmetic and is not verified here. These are different readings (charger DC side, Cerbo GX AC load and clamp current), all approximate, and we do not reconcile them. (video)
• Adding 120 V loads gave Cerbo GX readings of about 6,600 W, about 8,200 W and about 9,500 W, all approximate. At about 9,500 W an alarm was shown (we said the battery could only put out about 200 A from memory, and it was not clear on camera which device we meant), the battery management system switched the battery off, and we said we had technically overloaded the Quattro because it was above its rated 8,000 W at a cool room temperature. The owner has since said the shutdown at about 9,500 W was the Quattro's overload. We state both and do not say either is wrong. We did not record an exact timed duration for any level, and the applicable EG4 sheet revision for our battery is not recorded. (video)
• In part 2 we added an Eco-Worthy rack mount battery in parallel with the EG4 WallMount Indoor battery, and we said, with I think, that the two batteries were rated for about 200 A and 100 A out (our recollection, not checked against a document, and the document revisions for those batteries are not recorded). We did not state a verified combined figure, and nameplate currents do not establish what a mixed bank delivers. With the chargeverter alone the reading was about 5,600 W with about 5 A on the neutral. Adding loads gave readings of about 6,600 W, about 7,800 W, about 9,500 W with the EG4 battery reading about 149 A, then about 10,000 W, 10,500 W and a little over 11,000 W, all approximate. (video)
• At a little over 11,000 W in part 2 we said the Quattro reported that it was overloading or overheating and that the Cerbo GX showed a high discharge current alarm but no overload notification, while the Touch 50 showed a red light blinking. We said everything stayed powered on and that it was handled for a few minutes, that we did not know how long it could do so, and that the test ended because the kettle finished boiling. The owner has since said the garage was about 78 F (not stated as measured, and not stated for which test day), we said on camera it was warm, and we said a heater beside the unit was blowing hot air at its intake. We do not claim the unit can sustain these readings. (video)
• We set up two Victron Quattro 10 kVA units in split phase with an EG4 WallMount Indoor battery, and said one battery was not enough and the system cut out on multiple tests. We then added an AO lithium battery stack, an Eco-Worthy rack mount battery, and a second EG4 WallMount Indoor battery that had just arrived and was not yet connected. We said the communication was set up with only one battery. No load readings are given in that video. (video)
• We have run a Victron MultiPlus-II 48 V 3000 VA inverter/charger with 120 V output, a Cerbo GX and an EG4 WallMount Indoor battery. On camera the Cerbo GX screen showed the MultiPlus at 120 V and about 60 Hz with a 40 W load. In that video no solar charge controller was connected to this system, and we said the MultiPlus is only an inverter and charger with no solar charge controller built in. (video)
• We said the MultiPlus changeover to the inverter was almost instantaneous and that we expected no electronics to be affected. No measurement of the transfer time is documented in the transcript. (video)
• We have set up two identical MultiPlus-II 48/3000 units for a 240 V split phase system, linked over VE.Bus, with a Cerbo GX and an EG4 indoor wall mount battery. We said the units had to be the same model to do this. (video)

Specifications side by side

What we did not verify

• This page compares manufacturer figures. The only things that come from our own use are under 'What happened to us'. We make no claim about which product suits any system, and some rows in the table are marked as not like for like.
• Both datasheets state their ratings under conditions, such as ambient temperature and a non-linear load with a crest factor of 3:1. For the load tests the owner says the garage was about 78 F; he did not say it was measured, and we do not extend it to every test day. The datasheet's 25 C rating is 77 F. We state both figures and do not present our readings as tests at the datasheet's rated condition or compare them to the 40 C or 65 C ratings.
• The readings in 'What happened to us' were spoken from a Cerbo GX or Touch 50 screen, a charger display or a clamp meter, and are approximate. No exact timed duration at each reading is documented (in part 2 we said only that the Quattro handled the overload for a few minutes), and the owner has not confirmed the exact loads, wiring or settings, so this page does not show that either product can sustain any level, and the load tests are not rated tests.
• In our load tests the shutdowns were attributed on camera to the battery. The owner has since said the shutdown at about 9,500 W was the Quattro's overload. We record both, give no further cause, claim no rated overload limit, and do not say this establishes the Quattro's capability. The battery ratings we quoted on camera were from memory. EG4's WallMount Indoor 280Ah sheet, version 1.1.8, lists 140 A maximum continuous and 200 A for 30 minutes, and its changelog says an earlier revision listed 200 A continuous. We do not call our statement false; the applicable revision is not recorded, and nameplate currents do not establish the deliverable current of a mixed bank or the cause of any shutdown. The Eco-Worthy rating was not checked.
• The load tests used a 120 V Quattro with a Victron auto transformer, whose model number we did not record (the owner says it was the higher-amperage, US version), and our spoken neutral current limits were guesses, so nothing on this page states the auto transformer's limits. Our wiring in those videos was for demonstration only and is not shown as a method.
• Our videos were published 2025-04-04 (ghWkEtrggew), 2025-04-27 (RdVQvhkYXZA), 2025-05-02 (EaLXBSsnxa0), 2025-05-09 (4qe2XhWqDNo), 2025-08-23 (XKxhORXp0Pw), 2024-08-16 (gXKkSoRidAg) and 2024-11-29 (pMTB4NYTx9s). Neither datasheet prints a version or date, so we cannot place them relative to the videos. The Quattro datasheet's file metadata is dated 2026-04-14, which is after the Quattro videos. The owner confirms the Quattro is the 48 V 10 kVA 120 V model; its exact label, firmware, serial number and UL1741 status are not recorded, and neither are the battery model names, quantities, firmware and sheet revisions, or the exact timed duration at each reading. The MultiPlus-II variant we filmed is also not recorded.
• Sizing a battery bank, solar array, wiring or protection for either product is work for a licensed professional using the manufacturer's current documents.

Questions and answers

How much higher is the Quattro's continuous output than the MultiPlus-II's?

Victron's datasheets list 10000 VA (8000 W) at 25 C for the 120 V Quattro 48/10000 and 3000 VA (2400 W) at 25 C for the MultiPlus-II 48/3000, per unit, with different figures at 40 C and 65 C. We did not measure either against its rating.

Does the MultiPlus-II have two AC inputs like the Quattro?

No. Victron's Quattro datasheet describes two AC inputs with an integrated transfer switch. The MultiPlus-II datasheet describes one AC input and two AC outputs.

What did you see when you loaded the Quattro?

Readings of roughly 8,000 W, about 9,500 W and a little over 11,000 W, all approximate and read from a Cerbo GX screen, with shutdowns and alarms. On camera we attributed the shutdown at about 9,500 W to the battery; the owner has since said it was the Quattro's overload. No exact timed duration or temperature was recorded, so they do not show a sustained rating.

Can a 120 V Quattro give 240 V?

Victron's datasheet says two Quattro units can be configured for split phase. In one video we ran one 120 V Quattro through a Victron auto transformer for 240 V and 120 V loads. The owner says it was the higher-amperage, US version; the model number and its limits are not recorded here, and this is not a method.

Which one should I buy?

We do not make that recommendation. Their specifications are listed above, and the right choice depends on your loads and system, which a licensed professional can size.
