Axpert Aerox 5.2 kw not working witout battery

That model doesn't exist on the voltronic power website nor inverex website which according to your video is what it says on the screen (I assume it is the brand).

Are you sure you don't have a fake?

Anyway the newer versions of the Axpert, namely VMIII and King won't turn on without a battery attached.  That is why it is sold as off-grid, you have to have a battery.  If you don't want a battery the Infini solar is more like what you want.

Looks like Axpert VMIII based on specs

Except that the Axpert VM III doesn't allow paralleling (no Value model does) or grid tie, and it doesn't mention batteryless operation .

The Axpert VM II does mention batteryless operation, certainly has no grid tie, but has the older display and doesn't look like this one.

The Axpert II (and others) allow paralleling, but don't allow batteryless operation or grid tie and have the older display and looks.

The Axpert King seems a closer match to me, but still doesn't have grid tie or mention batteryless operation.

The Mustpower PH1800 series have the grid-tie and self consumption feature; maybe this is something that Voltronic Power are learning from one of the clones?

Maybe it's a new Voltronic Power model, perhaps requested by Inverex, and possibly exclusive to Inverex (perhaps for a limited time)?

Or maybe Inverex have decided to become the latest clone maker (while possibly still remaining an official Voltronic Power reseller??), except it's a clone with extra features?

I thought so too then I looked at the specs and there are several missing features, most importantly 0ms transfer time

The thing is they don't have ANY hint of it on their web-site.  I think it is more likely it is a fake made by a company claiming to be Inverex.

But I bought it from the company's display center

Sometimes even the suppliers don't realise that this source from China is illegitimate, while that one which looks much the same is legitimate.

But perhaps the Axpert Aerox will appear on the Voltronic Power website soon.

So there are two web-sites of a company claiming to be Inverex:

http://www.aptinverex.com/

https://inverexpower.com/

Both do seem to be the same company based on the contact us address.

I've never seen any Axpert models that don't exist on the Voltronic power web-site.  Even when the King came out it was immediately on the Voltronic web-site.  Point being, this is either a "fake" or they are re-badging an Axpert with a new name.  Giving it a different name is not unheard of.  The MPP Solar are real Axpert inverters and they have a different name.

Are you staying in Pakistan or did you import to South Africa?

Aerox seems to be good.

He probably brought it in Pakistan, and probably lives in Pakistan. 

 

@mazo78 that unit doesn't look like a genuine, or rebranded Axpert inverter. It's a probably a fake knockoff. 

That being said, most of the Axpert inverters need batteries to work

@mazo78

to me it looks like Aerox 5.2 KW is able to run without batteries only if you enable feeding into the grid in the program 08.
At the same time,  it might need you to set program 01 to SUB or USB.

I'm not sure, but it's worth a try:

Anyway, if you've been able to solve the issues in the meantime, can you update us on the results, please?

Thanks!

I am Adnan from Pakistn. I am using Aerox 5.2 for the last two months and it really is a mystery to me. as I could not find any voltronics or mpp solar similar models. Yes it can run battery less with or without feeding to grid. It is not  a double conversion like king but is a hybrid inverter. I opened mine to take a look inside. It is in warrenty so was not able to take the cover apart. Kindly Coulomb  and other try to figure out what this thing is and is it a voltronics made unit.

U1 is 72.10

U2 is 01.22

U3 is 88.88

This brochure from Inverex says it has zero transfer time, implying double conversion: http://www.aptinverex.com/wp-content/uploads/2018/04/Aerox5.2.pdf

Yet the manual gives normal Axpert transfer times: http://www.aptinverex.com/wp-content/uploads/2018/03/APT-AEROX-5.2KW-manual-20190117.pdf

So one has to be wrong, and it seems obvious that it's the brochure. This has no doubt fuelled a lot of the confusion.

I think it's an Axpert MKS III, i.e, like an Axpert VM III, bit without the "V" (Value line) limitations. So it has the ability to parallel up to 9 units, it has the 450 V MPPT/SCC, and has the latest display with Bluetooth etc ability.

But it also has the ability to blend PV and AC-in power, and also to feed (export) power to the grid. These features presumably require certification from testing laboratories, and Voltronic Power don't seem to want to do this on behalf of all their resellers, so maybe that's why this is (at least for now) an Inverex-only product. Perhaps the certification requirements in Pakistan are less, or the authorities turn a blind eye, I would not know. I see no ability in the Aerox menus to select a country code, as is usual with grid interactive inverters.

It does look like a Voltronic Power manufactured product; the layout, components, and the numbering on the printed circuit boards are very Axpert-like.

That's really surprising. Could you double check this, please? Main firmware version 72.10 is usually for a 5.0 kW PF1 inverter-charger with 64 V option and 145 V MPPT/SCC. I have a copy of a 72.10 firmware, and it doesn't have menu option 08 ("Solar energy feeding to grid configuration"). Is it possible that 72.10 is a typographical error?

This is presumably a third processor that handles the Bluetooth etc, and possibly the ability to talk directly to a Pylontech BMS (suggested in some brochures, but we know that sadly the brochures aren't necessarily accurate).

I believe that the inductor on its own printed circuit board nearest your thumb in the first photo is the boost inductor for the Solar Charge Controller.

This is the first Voltronic Power inverter-charger that I've seen with Urdu (?) characters on a sticker, but presumably that's a customisation for Inverex.

Thanks for the internal view photos; these are always welcome.

Yes U1 is 72.10 . it has no operation logic setting 10 in menu so i think as it can blend solar and utility and the inverter is running so inverex folk thought why not say zero transfer time as marketing tactics. As i talked to couple of inverex guys and they clearly don't know what 0 ms is or any thing about double conversion.

When choosing USB in setting 01 it does not take utility when solar is available and always work in hybrid mode using solar first???

Can it be made a pure double conversion by some firmware upgrade by not using grid tie feature???

How to reset these units to factory defaults???

What is this board upside down on the heat sinks, i had not seen this in other axpert models. pic attached

I'm shocked! 😮  Not. 😐

It looks like they did a copy and paste from an Axpert MKS manual. Actually, Axpert MKS II manuals are the same (with different names for some of the modes).  It seems that these aren't updated to reflect the ability to combine PV and Utility power.

It seems clear however that in this mode, Utility has highest priority for connecting to loads, so I don't understand "When choosing USB in setting 01 it does not take utility when solar is available".

No, for double conversion it needs a full rated power AC to DC converter.

Use the provided software. Do these come with WatchPower?

I believe it's the SCC board, see for example this photo from my 2015 model:

Internal_view_2.jpg

The clincher would be if you can see the metal straps heading to the PV connector between the fans (at the bottom of my photo, and at the right side of yours; I can't be sure from your photos). Your SCC board looks a bit different to mine, as mine is one of the last 60 A models they made, and also it's an interleaved buck converter with two inductors. Yours is a boost converter, and seems to have only one inductor.

Hi @Adnan Idrees

I am from Lahore also and considering to buy this inverter .How your experience has been so far specially its batteryless operatoion ?

I intend to run 2 1.5 Ton Acs(GREE Inverter based) during daytime only with SUB setting ofcourse there will be no battery 

I would like to talk to you if you dont mind my number is 0300 4055732 or [email protected] 

 

Thanks
