Error 05 is output short circuit and 09 bus soft start failed. 
You have had great service out of the inverter 😀
This is one for @BritishRacingGreen or @Coulomb

The MOSFETs in these models run right along the side, hidden under an overhang. That's where you usually see the worst carnage.
In this case, you should also check the IGBTs on the middle heatsink. Sometimes the damage is fairly subtle, like a crack in the epoxy. 
Unless you are handy with electronics, fir example you have access to a desoldering station, it's probably time to retire this inverter. 

Awesome! I would try all the thing you mention. Enough guidance to go one step further
Thanks a lot again, you have been so careful to explain things that I would probably need to know in advance to do any reparation.

Heya Luis, that's a rough one and sadly when not done right you just end up burning replacement components constantly. 
So the DC-bus is likely damaged, the PV connects to the charging circuit through there so no wonder the PV isn't charging. The real issue is that if a single MOSFET blows, you have to replace every other MOSFET and possibly the MOSFET controls. If you want to check the MPPT you can try reading the voltage across the 2 bars that connect from the MPPT to the mainboard (As long as it's the same as the Axperts I work on), that is where the MPPT pushed voltage to the charging circuit.
Otherwise, due to their sensitive nature, if one MOSFET blowing will damage others (may not be visibly blown but there is often invisible damage). So, the ones I work on have IRFB3307ZPBF MOSFETs and I know the values should be the following:
Resistance:
GS: 11.7k/GD: 250k/DS: OL
Then when Diode measuring you should get:
SD: 0.43V/DS: OL
So you can check the relevant values for the IRFB4110 and try sort the damaged ones from the ones that are fine but you'll likely have to replace them all...

You're welcome Luis! I have been repairing these things for a while now so happy to share my experience!
So between the 2 MOSFET heatsinks, you should see two bars that connect to the smaller MPPT that is mounted above. They should be a socket size 5,5mm. Those are the points where the MPPT feeding into charging, picture below:
 
If you google the MOSFET spec-sheet, it should show you the label of each leg and what values to expect. Some measurements are just a resistance measurement, so you will need a multi-meter that can measure resistance. The other is a diode reading, since there are semi-conductive gates between certain legs and it should give you the breakdown voltage for that semi-conductive gate.

Honestly, I have nothing against people repairing their own devices and I advocate for the right to repair. However, if it feels like you're out of your depth there is no shame in taking it to someone that does repairs like myself. The reality is that these are extremely complex devices that can be a major pain to test and work on, sadly I don't know anyone in Spain to recommend xD

Exactly! Thanks so much, these two parts were burn. A Valencian technician repared it and works fine again.

Indeed. A sadly common problem with the comms boards is that the small transformer (technically a multi-winding inductor) overheats and there are shorted turns. Those transformers are one of the very few components that you can't order from an electronic component supplier; they are all custom wound. Check for discolouration of the transformer (the thing with yellow tape on it).
I've heard of people obtaining replacement communications boards from Ebay or the like. Fortunately, the comms boards haven't changed in function all that much, so one from a slightly different model should be fine (as long as it has the right connectors).

My concern with that is not just replacing the diode, which is easy, but why it blew in the first place. Diodes don't usually break like that unless their maximum current was exceeded by a LOT (if you only exceed it by a bit, the diode just gets too hot and, if it gets hot enough, may even desolder itself from the PCB) or their max. reverse voltage was exceeded by a fair amount. So I would guess that something else broke first and the blown diode is just a symptom. My guess would be that something else blew short circuit and the diode had to carry the short circuit current, which caused it to blow as well.

That part costs under R10:

It will of course cost a lot more for shipping. And of course, it may not be the only part that failed.
It's just a high speed 1 A silicon diode. Rated at 600 V, but it only need to be about 50 V. You might be able to buy one at a local electronics store (I have no idea where you'd go in South Africa). Even if it's a through-hole part, you could probably make one fit to see if that fixes the problem (if you or a friend is handy with electronics).

Hi
Thats true i am a Voltronic distributor & service center. But now i am living in Netherlands i am only selling Lifepo4 cells for Voltronic and Victron here.
So all of our Voltronic stock is in Istanbul Turkey and i preffer not to supply parts within Europe. As you are looking the cheapest solution.
Cheapest option for you to check with @PeterGutti from Spain. He got a new card from me  and he promised to buy me coffee when i go Alicante in summer
If he kept his old card maybe he may unsolder this diode from his old card and send to you. Good luck.

Bumping this old thread...My Axpert VMII's (5Kva) comm card stopped working (USB & RS232). Opened it up yesterday and looks like its gone. Looking for a replacement part but it doesn't seem to be available locally with the Axpert distributors here. Would appreciate any leads @Coulomb @plonkster @Mars
Here's the image of my comm card
