Surge power time of phoenix inverter

Good morning.


How many seconds can a Phoenix inverter withstand peak power?

Specifically the 500VA?

Many manufacturers in the data sheet specify the possible time at various overload levels.

victron no.

Many low frequency inverters with transformers (such as the Phoenix victron) claim surge power over 3x the nominal power.


Victron instead declares a surge power of about 2x, like the cheap high frequency inverters.


Can anyone help me clarify?

Thank you

Thank you! I now these video.


But is the same for low power models like phoenix from 250 to 1200 VA?

Phoenix 12/500...
Pnom = 500 watts
P30 = 525 watts
Pstartup = 900 watts

I assume ...
Pnom = continuous
P30 = 30 minutes ?
Pstartup = Victron does not define Pstartup but Quattro states 2X for 1/2 second

Ok thanks you..


seems to be what I see in reality with the Phoenix 500.


I actually see startups up to 1200w for a few moments.


but with 800w it lasts about 10 seconds.


Why does it say in the webinar that the multiplus supports startup for.2 minutes?

it's different?


where did you find this data on the phoenix 500?


there are many high frequency inverters that claim up to 250% in startup.


and for 5 seconds.


it seems strange to me that the phoenix with a low frequency transformer has a startup of only 200% for half a second.

Thank you

I have tested phoenix 500 now.


At 525/540w handle 30 second.

At peak power 2 seconds.


Totally different from that says the webinar of quattro or multi.


I'm confused.

this 360 euro, 3,000 W low-frequency with transformer Chinese inverter supports a peak of 300%.

This Italian high frequency inverter of 3000w and 1000 euros supports a peak of 8000w for 5 seconds.

What is the point of having a victron with a transformer that weighs a ton if it bears less power than a Chinese one with a transformer, and less than a high-quality high-frequency inverter?

OK, so "P30" means 30 seconds, not 30 minutes. Good to know.

Are you sure the Phoenix 12/500 is "Low Frequency"? Victron states, High Frequency Hybrid Technology. I tend not to use terms like "LF" vs "HF". Since, there is no official definition.

I get my information directly from the Victron manual. Written information is usually more accurate. Unfortunately, Victron never defined the terms: "P30" or "Pstartup" in their manual.

I have not seen the webinar for the Phoenix 12/500.

Victron Phoenix 500 with toroidal transformer .

Max efficiency: 90%

Surge: 900

Weigh: 3.9 kg

Zero load consumption: 6w



EPEVER STI 500 with toroidal transformer.

Max efficiency: 91%

Surge: 1600

Weight: 7.3 kg

Zero load consumption:5w




Epever STI cost the same or a little less than victron phoenix.

All specs are better and the tech info are much more detailed.(like 4 different times of power, and various levels of efficiency). These is a really serious attitude of the company, in my opinion.


The only Better spec in victron is the frequency tolerance. 0.1% vs 0.2%


What's the technical reason why exactly the same technology (same bridge-toroidal transformer) of epever have a surge power almost 2 times of victron? And the reason why Epever weight a lot more?

If you don't like / agree with what you have there's four options.. (sort of )

1 - Send it Victron (under warranty?) for testing.

2 - Accept this is the way of things and move on.

3 - Buy Chinese...Good luck with that.

4 - Buy a more powerful Victron Inverter.


Your call Good luck i hope things get sorted .

ps i have a Phoenix inverter 1200va & two Inverter RS Smart 48/6000.

I never said I'm not happy. i said a startup of 2x is quite disappointing for a transformer inverter.


high quality transformer inverters reach 3x... and not only high quality.


China produces a lot of garbage, but also great products. even higher than European and American products. China produces garbage because Westerners pay it to produce garbage.


If you pay the right amount, China produces the highest quality. (Apple etc etc. The same victron products are produced in china and India, and victron rebranded a number of chinese-brands products in the past, only increasing the price. for example some old pwm controllers).


Saying " good luck with a Chinese product" means nothing. Almost everything is Chinese.

Where are the lithium cells of Victron batteries produced? From who?? I don't know.

Almost all of the lithium cells in the world are of Chinese production.


I have seen epever ipower HI(HF) and epever NPOWER (LF square iron transformer) inverters tested on an oscilloscope and they look very good.


they also cost the same as a Phoenix victron.

And they are designed and manufactured by a Chinese company

Also toroidal transmormer and capacitors inside victron inverter are 100% made in china, from cinese Company. Keen Ocean inductors and Sancon capacitor's.


Nothing USA made or Japan made or EU made.
