What the manufacturer documents

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)
EG4's 3000EHV-48 specification sheet, version 1.1.2, lists a rated output of 3 kVA / 3 kW, pure sine wave, 110/120 VAC plus or minus 5 percent at 60 Hz or 50 Hz, and surge capacity of 2 times the rated power for 5 seconds. It also lists overload protection of 5 seconds at about 150 percent load and 10 seconds at 110 to 150 percent load. The sheet gives no temperature for the 3 kW rating. (eg4electronics.com)
The Victron datasheet 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 charge voltages of 57.6 V absorption, 55.2 V float and 52.8 V storage mode. It lists an AC input range of 90 to 140 VAC at 55 to 65 Hz, a transfer switch rating of 50 A and a maximum AC input current of 50 A. (victronenergy.com)
The EG4 3000EHV-48 sheet, version 1.1.2, lists battery charging current of 60 A from AC and 80 A from PV and AC together (both at 120 VAC input), and a bulk charging voltage of 58.4 V for a flooded battery or 56.4 V for an AGM or gel battery, with a floating voltage of 54 V. It lists an AC input of 95 to 140 VAC for electronics and 65 to 140 VAC for home appliances, 50 Hz or 60 Hz with automatic detection, and a maximum AC input voltage of 150 VAC. For short circuit protection it lists a 30 A circuit breaker in line mode; it does not list a maximum AC input current as such. (eg4electronics.com)
The Victron datasheet says the MultiPlus-II takes over supply to the connected loads in a grid failure in less than 20 milliseconds, and that it has two AC outputs: the main output, and a second output that is live only when AC is present on the input. (victronenergy.com)
The EG4 3000EHV-48 sheet, version 1.1.2, lists a transfer time of 10 ms typical for its UPS setting and 20 ms typical for its Appliances setting. (eg4electronics.com)
The Victron datasheet has no solar input section for the MultiPlus-II. It says the unit can be used in off grid as well as grid connected PV systems and is compatible with both solar charge controllers and grid-tie inverters. (victronenergy.com)
The EG4 3000EHV-48 sheet, version 1.1.2, lists a built-in solar input with one MPPT, a rated power of 5000 W, a maximum PV array open circuit voltage of 500 VDC, an MPPT voltage range of 120 to 450 VDC, a maximum current draw of 18 A and a maximum PV charging current of 80 A. (eg4electronics.com)
The Victron datasheet lists maximum efficiency of 95 percent and zero load power of 11 W for the 48/3000/35-50 (7 W in AES mode and 2 W in Search mode). It does not state battery voltage, temperature or other conditions for those figures. (victronenergy.com)
The EG4 3000EHV-48 sheet, version 1.1.2, lists idle power consumption of under 70 W without stating the conditions, battery to inverter efficiency of 94 percent, PV to inverter efficiency of 97 percent, and a line mode efficiency entry for a rated resistive load and a fully charged battery. That entry shows 95 percent with an unreadable character before it in the sheet itself, and we could not verify what qualifier the character stands for. (eg4electronics.com)
The Victron datasheet lists an operating temperature range of -40 to +60 C (-40 to 140 F) with fan-assisted cooling, protection category IP22, 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. Its listings row shows UL1741 for this model. (victronenergy.com)
The Victron datasheet says up to 6 units can operate in parallel, and that two units of the same model can be connected for a 240 V split phase output. (victronenergy.com)
The EG4 3000EHV-48 sheet, version 1.1.2, lists an operating temperature range of -10 to 55 C (14 to 131 F), an operating altitude of 0 to 1500 m, an enclosure rating of IP 21 (indoor use), a net weight of 8.2 kg (18 lb), a safety certification of CE and a warranty of 3 years. On its specification page it lists dimensions, labelled in the order depth, width, height, of 16.5 x 13.4 x 5.6 in (420 x 340 x 142 mm), while its first page gives 17 inches tall, 11.75 inches wide and 4 inches deep. (eg4electronics.com)
The EG4 3000EHV-48 sheet, version 1.1.2, lists up to 12 units in parallel (12 single phase, 2 x 6 split phase or 3 x 4 three phase) with CAN parallel communication and a built-in parallel kit through an RJ45 port. (eg4electronics.com)
Victron's Cerbo GX manual, revision 41 dated 09/2026, lists third-party batteries known to have been tested, and EG4 is not among them. For batteries not on that list it says many are compatible, permitted under warranty, and need additional information and support from a local supplier. A separate line in the manual says to use only batteries listed on Victron's compatibility list to ensure proper communication, and that others are not supported. (victronenergy.com)

What happened to us

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)
We have run an EG4 3000EHV-48 for a few months in different settings. In the review video it had been running a 12,000 BTU mini split for a few days from a battery that was mostly full, with no solar and no grid connected to it on camera (the solar array was on a 6000XP), and with the battery communication working with a lithium battery pack that was not an EG4 battery. (video)
We built a portable 5 kWh power station around a 3000EHV-48 that we called the second generation, with an EG4 48 V 100Ah waterproof battery, and said it had powered a 12 inch miter saw, a 10 inch miter saw, a compressor and a heat gun. No timed or controlled measurement is documented in the transcript of that video. (video)

Specifications side by side

From Victron's MultiPlus-II 120 V datasheet (no version printed) and EG4's 3000EHV-48 sheet (version 1.1.2), not our measurements. The last column says whether the two figures are like for like.
Specification	Victron MultiPlus-II 48/3000/35-50 (120 V)	EG4 3000EHV-48	Like for like?
Continuous output	3000 VA at 25 C (77 F) per unit (non-linear load, crest factor 3:1); 2400 W at 25 C (77 F), 2200 W at 40 C (104 F), 1700 W at 65 C (150 F)	Rated 3 kVA / 3 kW; the sheet states no temperature for this rating	Partly. Victron states the temperature for each figure, including the 3000 VA rating, and EG4 does not. All figures are per inverter.
Peak or surge output	Peak power 5500 W, duration not stated	Surge 2 times rated power for 5 s; overload 5 s at about 150 percent load, 10 s at 110 to 150 percent	No. The two sheets define the figure differently.
Output voltage and frequency	120 VAC plus or minus 2 percent, 60 Hz plus or minus 0.1 percent	110/120 VAC plus or minus 5 percent, 60 Hz or 50 Hz	Comparable nominal output; the sheets state different tolerances.
Battery voltage	DC input voltage range 38 to 66 V	Nominal 48 VDC; low DC cut-off 38.4 to 42.0 V depending on load; overcharge protection 63 V; no operating range stated	No. Victron states a range; EG4 states a nominal value and trip points.
Battery charge current	35 A maximum (up to 25 C / 75 F ambient); absorption 57.6 V, float 55.2 V	60 A from AC and 80 A from PV and AC together (at 120 VAC input); bulk 58.4 V flooded or 56.4 V AGM or gel, float 54 V	Partly. The EG4 80 A figure includes solar charging, which the Victron has no input for.
AC input	90 to 140 VAC, 55 to 65 Hz; maximum AC input current 50 A; transfer switch 50 A	95 to 140 VAC for electronics, 65 to 140 VAC for home appliances; 50 or 60 Hz automatic; 30 A circuit breaker listed in line mode; no maximum AC input current stated	Partly. EG4 does not list a maximum AC input current.
Transfer time	Less than 20 ms	10 ms typical (UPS setting), 20 ms typical (Appliances setting)	Partly. Victron gives a limit and EG4 gives typical values per setting.
Built-in solar input	None listed; the datasheet describes use with separate solar charge controllers or grid-tie inverters	One MPPT, 5000 W rated, 500 VDC maximum open circuit, MPPT range 120 to 450 VDC, 80 A maximum PV charging current	No. Only the EG4 has a built-in solar charge controller.
Idle consumption	Zero load power 11 W (7 W in AES mode, 2 W in Search mode); no other conditions stated	Under 70 W; no conditions stated	No. Neither sheet gives comparable test conditions, and no measurement of either unit is documented in the transcripts.
Efficiency	Maximum 95 percent	Battery to inverter 94 percent, PV to inverter 97 percent; line mode entry shows 95 percent with an unreadable character before it in the sheet, whose meaning we could not verify (rated resistive load, battery fully charged)	No. The sheets define efficiency differently, and the EG4 line mode entry is partly unreadable.
Operating temperature and altitude	-40 to +60 C (-40 to 140 F), fan-assisted cooling; no altitude limit listed	-10 to 55 C (14 to 131 F); 0 to 1500 m	Partly. Victron lists no altitude.
Weight and size	19 kg (42 lb); 572 x 277 x 147 mm (22.5 x 10.9 x 5.8 in), listed in the order height, width, depth, for the UL1741 listed model; the datasheet gives 536 x 277 x 147 mm for a model that is not UL1741 certified	8.2 kg (18 lb); 420 x 340 x 142 mm (16.5 x 13.4 x 5.6 in), labelled in the order depth, width, height, on the specification page, while the first page gives 17 in tall, 11.75 in wide and 4 in deep	Yes for weight. EG4's sheet gives two different size sets and we have not resolved them.
Ingress rating	IP22	IP 21 (indoor use)	Yes
Warranty	Not stated on the datasheet we cite	3 years	No. We did not check Victron's separate warranty terms.
Certifications as listed	UL1741 in the listings row for this model; the datasheet also lists CSA 22.2 107.1-16 among its safety standards	Safety certification listed as CE	No. The sheets list different things and we have not seen certificates.
Units in parallel	Up to 6; two same-model units for 240 V split phase	Up to 12 (12 single phase, 2 x 6 split phase, 3 x 4 three phase)	Partly. The counts depend on topology and are not the same measure: EG4's 12 is a total split among single, split and three phase arrangements, while Victron describes parallel, same-model split phase and three phase sets separately.

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 many rows in the table are marked as not like for like.
The MultiPlus-II has no built-in solar charge controller and the 3000EHV-48 does, so these are different kinds of product. The Victron system we show also uses separate parts (a Cerbo GX and a display) and no solar charge controller was connected in our video. We did not price or compare those parts here.
Our videos were published 2024-08-16 (gXKkSoRidAg), 2024-11-29 (pMTB4NYTx9s), 2024-04-26 (GRNK03la2kA) and 2023-10-29 (g0Gr46-I-mM). The EG4 sheet is version 1.1.2 and bears a 2025 copyright notice, the Cerbo GX manual is dated 09/2026, and Victron's datasheet prints no date, so we cannot place it relative to the videos. The EG4 sheet's 2025 copyright notice and the 09/2026 Cerbo manual are later than the videos. The specifications are for the listed datasheet and sheet models only: the Victron model variant we filmed was not recorded, and the second-generation 3000EHV-48 in our video is not matched to sheet version 1.1.2.
The transcripts document no measurement of idle consumption, transfer time, efficiency or output limits on either product, and the owner has not confirmed whether any was made, so we cannot say whether the figures on either sheet match what we saw. The idle figures here are the makers' and are not comparable with each other.
EG4 is not on the list of tested third-party batteries in Victron's Cerbo GX manual (revision 41, 09/2026). That manual says unlisted batteries need support from a local supplier. We have run an EG4 battery with a Cerbo GX and MultiPlus-II, but seeing it work does not mean Victron or EG4 support that combination, and this page does not compare battery communication between the two inverters.
Our video of the 3000EHV-48 shows it with a non-EG4 lithium battery. We did not verify EG4's battery compatibility list for it.
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

Does the Victron MultiPlus-II have a solar charge controller?

Not built in. Victron's datasheet lists no solar input for it and describes using it with separate solar charge controllers or grid-tie inverters. EG4's sheet lists a built-in MPPT for the 3000EHV-48.

Which one has the higher continuous output?

The sheets do not compare cleanly. Victron lists 3000 VA at 25 C and 2400 W at 25 C, falling to 1700 W at 65 C, per unit. EG4 lists 3 kVA / 3 kW per unit and states no temperature for it.

How fast do they switch to battery?

Victron lists less than 20 milliseconds. EG4 lists 10 ms typical in its UPS setting and 20 ms typical in its Appliances setting. Our transcripts document no measurement of either.

Do both products have the same warranty?

EG4's sheet lists 3 years. Victron's datasheet does not state a warranty, and we did not check Victron's separate warranty terms.

Which 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.
