PeterGutti Posted October 17, 2017 Share Posted October 17, 2017 Hi everybody! The USB interface of my Axpert 5kva inverter is broken. Is anybody out there that does not use the USB interface? I'm running two Axpert 5KVA in parallel. One has RS232 the other has USB interface. Since months the USB interface is broken. The installer and salesman ordered vom Voltronic a replacement USB but received instead an RS232. He explained that Voltronic does not deliver replacement USB cards. (True? i don't know) Quote Therefore i ask you if you own a USB interface from an Axpert 5KVA and not using it, would you give it to me? Of course i pay for it and the shipment. I live in Spain, Costa Blanca, near Calpe/Denia, 100km south of Valencia Peter Quote Link to comment Share on other sites More sharing options...
PeterGutti Posted December 25, 2017 Author Share Posted December 25, 2017 Hi Cem! only now i'm reading your messages, sorry! As the Axpert inverter and ICC are running very smoothly i don't check the forum very often. ICC currently is connected with RS232-to-USB cable. and... yes i still would like to have a USB port. I could use it as backup. My dealer/supporter explained me that this replacement part cannot be ordered. Serial: 92931506100847 Quote Link to comment Share on other sites More sharing options...
Mars Posted December 27, 2017 Share Posted December 27, 2017 Hi Peter Hope i can help.I checked , we have attached cards in stock. Send me PM if it works. Quote Link to comment Share on other sites More sharing options...
PeterGutti Posted July 25, 2018 Author Share Posted July 25, 2018 I'm terribly sorry I just have seen your post offering a USB interface card. Mine looks a bit different: see images. With PM you mean my postal address? I will not post it here rather directly to you. Quote Link to comment Share on other sites More sharing options...

Mars Posted January 25, 2019 Share Posted January 25, 2019 @Chris Hobson @plonkster @The Terrible Triplett are well known forum writers. i guess they might help or know the ones who can help us/ A forum member Peter from Spain has a broken Communication card. Attached 2 photos. I am a Voltronic distributor in Europe trying to help Peter. Attached PDF is what i have in stock. How we can be sure this will work for Peter ? thank you for your kind help Big KS5 COMM CARD.pdf Quote Link to comment Share on other sites More sharing options...
Coulomb Posted January 26, 2019 Share Posted January 26, 2019 (edited) That one should be fine. For whatever reason, the communications board has evolved far more than the other parts of the inverter-chargers; see for example this post. His is a 2015 model (looks exactly like the customer's); yours is a 2017 model (we don't have a photo of one of those as yet). They should inter-work just fine. Edit: I pinched a photo so we have a 2017 board photo; I hope you don't mind. I'm happy to blank the serial number if you thing that's important (I don't). You can see that there is little to no real difference between the 2015 and 2017 boards. Edited January 26, 2019 by Coulomb Quote Link to comment Share on other sites More sharing options...
Guest Posted January 26, 2019 Share Posted January 26, 2019 @Mars Thanks for that. With Voltronic, Coulomb and @weber are the men to speak to. Quote Link to comment Share on other sites More sharing options...
PeterGutti Posted January 26, 2019 Author Share Posted January 26, 2019 Hi everybody! I'm impressed how people in this forum support each other! Hope i can give back something in the future. Yes,, my cards looks exactly like the 2015 fotos in the pdf. I would be happy to buy one. Will send PM with address. Energy-Jason 1 Quote Link to comment Share on other sites More sharing options...
PeterGutti Posted March 8, 2019 Author Share Posted March 8, 2019 Good news: The USB interface Mars sent me finally works. I now can connect both, BMV and Voltronic, over USB to ICC. Before, under mixed communication (RS232 for Voltronic and USB for BMV) the connection failed every now and than: After 80 hrs ... 800 hrs of ICC running time. I learned that this might be a problem of Linux(!?). But now no longer its an issue. The replacement was not that complicated: make Inverter powerless: Power off, disconnect batteries and panels (by pulling fuses) disconnect old card, unscrew it screw in the new card and connect the three plugs (cannot be confused) back on power by inserting all the fuses and switch the inverter power on Connect USB cable and watch! It did not work the first time, so i left it for a few days. Today i checked all the connectors and tried again. I have been told, that the inverter may have to be reset multiple times to make changes work. But today i did not power off the inverter... I hope with this setup the communication problem i experienced are over! Thanks again to Mars who shipped a replacement part within days. Great support!

StrikerX Posted July 4, 2019 Share Posted July 4, 2019 (edited) 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.

Coulomb Posted July 4, 2019 Share Posted July 4, 2019 (edited) On 2019/07/04 at 6:24 PM, StrikerX said: looks like its gone. The transformer (really a multi-winding inductor) appears to be browned in one spot; it's not a an order-able part. Is should be possible to order a comms board from the same place you got your inverter. They'll want to see a photo of your inverter's bar-code to be sure you're not a clone owner, or some other reseller's customer. Failing that, you occasionally get people not needing their comm boards and willing to sell, or getting one from an unrepairable inverter. You might be able to get them from Ebay or Ali Express, but I don't hold much hope of that. A really desperation move would be to make a separate power supply from an isolated DC-DC converter module and a rectifier, but you'd need pretty good electronic skills to pull that off. Sorry, the options are not great. I'd work a little harder on your supplier, pointing out they're the one that should be supporting their product.

Actually, looking at the partial schematic trace in this post, it might be easier to figure out your own multi-turn inductor, and replace the diode and 0R resistors (used as fuses, presumably). Take the original inductor out altogether. You could probably use a readily available pot core. I don't have the know-how to design the inductor (what material, air gap, and number of turns).

Mars Posted July 5, 2019 Share Posted July 5, 2019 Hi @StrikerX i can not see photos. If @Coulomb or @weber or @PeterGutti can see photos maybe they can compare with my old photos. If it is matching i may supply you card. Quote Link to comment Share on other sites More sharing options...
Coulomb Posted July 6, 2019 Share Posted July 6, 2019 (edited) On 2019/07/06 at 6:04 AM, Mars said: maybe they can compare with my old photos. They're not the same. Mars' has the clean contact relay and connector, StrikerX's does not. The inductors also have different part numbers, sadly. Despite that, if you can fit the larger board in somehow, I believe there is a small chance it would work, but I can't be certain. The HFPW (High Frequency PoWer) may come in on a different connector, or they might be paralleled so it doesn't matter.

Would appreciate any leads @Coulomb @plonkster @Mars Here's the image of my comm card Hello to everyone, I just signed-up to this forum because I had exactly the same problem, the diode PJ705K RS1J just broke and burnt. Fortunately, the inverter works unplugging the comms-port-board, can I break something else working regularly with the inverter? It seems that goes good, what gives me the chance to continue working while I find a replacement. Does anyone knows where I could find a spare part of this board? I found a technician near Valencia, Spain, who can provide a replacement one for 80€ aprox, but it seems to be pricey for such a little board (and problem). Thank you so much for all the attention that a post here seems to create. Salud!! Quote Link to comment Share on other sites More sharing options...
Mars Posted October 8, 2020 Share Posted October 8, 2020 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. 4ldesign 1 Quote Link to comment Share on other sites More sharing options...

That part costs under R10: https://www.mouser.co.za/ProductDetail/Vishay-Semiconductors/RS1J-E3-5AT?qs=lBalI7KQBwqGckUc1sVLow== 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). 4ldesign 1 Quote Link to comment Share on other sites More sharing options...

Thanks a lot, I will try to check first if I can find the diode in a local electronics provider. However, I will keep in mind the solution you gave me. Cheers!
