Hi I'd connected my Axpert Ultra 11K to my Daly BMS with RJ45 cable and i'm using CAN bus. I have the Li-Ion indicator on inverter that mean connection is Ok I'd selected "LIB" in setup battery. I'd selected Voltronic Can Bus communication in my BMS interface. At this time, setup is OK. I have voltage but not the percentage, it stay at 0%, on my BMS it indicate 40%, so the screen on inverter after some few minute flashing red to indicate some problem. Battery is charging but setup is 10% for to stop discharge and 80% to start discharge, as no percentage is getting back inverter is in fault. Do you know what can i do ? Thanks

Hi Coulomb The fuse is ok, mainboard conduction around contact are ok but the inverter give me a alert that the battery is missing so the problem will stay even if i repair and clean correctly the damaged area. Thanks

Hi First, i'd tested the internal fuse, he is ok, he didn't break. I'd put away the mother board from the bow to check motherboard. Nothing appear to be burned, Mosfet seems to be good, only the place of the fuse so i don't understant what happen. Do you have a idea ? Thanks

So i'd update my Ultra 11kW by isolar application. My dealer ask me my serial number, has contacted Voltronics to get code for to upload on my inverter and send me back my code. Now when you go back to application you can check "Firmware Update" and popup will ask you what you want to update and your code. Now this is my setup : MCU1 and DSP only change

Hi Normally with isolar application you can udate the inverter but it's not working !!! My dealer give me code to update by application but i don't know where to put this code. I'd found also the post from Coulomb member here --> https://forums.aeva.asn.au/viewtopic.php?t=9165 But i would like to use isolar application to do it. Thanks

Hi Do you know where to find this firmware ? I went to Voltronic website, nothing for firmware !!!! This is what i have. Thanks

Hi I get the logfile from my burned inverter but i understand nothing ☹️ If you can see something wrong into this logfile ? But i still don't understand, the fuse inside the inverter as burned, it's a 200A. My battery pack have 175A fuse protection and didn't burn, so why the internal fuse has burned and not the external ? My BMS is a 250A so it's not him who has protected the battery pack. Thanks 03102562.TXT

Hi I really don't know ? Perhaps some mosfet defect ? Perhaps bad electronics compenent ? I didn't change the setup since one year so ? Thanks

Hi I'd received my new Axpert Ultra 11K so i'd open the 7.2kw. As you can see battery fuse has burned and motherboard too a little i think. What can be the problem ? it was running well since one year. So repair shop ask me 300 euros to change mother board, can i find this mother board myself and install it ? Some link ? Thanks ps : Shop can send me motherboard for 250 euros.

Thanks fhocorp, je suis en région parisienne. La boutique m'annonce une réparation dans les 200-300 euros. Merci

Hi Everything is ok, battery and BMS are OK. I's was working perfectly until 1 week, it was smell burned electronic component in the garage, so i think something has burned inside. So new one is needed. Thanks

Hi Yes, there is battery voltage on inverter terminal. I'd check with my voltmeter and bypass BMS to be sure it's not him who is defect. Perhaps just board to replace inside ? When i will have the new i will open it to check what's wrong. Thanks

Hi everybody My Axpert Max 7.2kW has lost battery detection. I'd checked battery and BMS, everythink are ok, so i think it's inverter the problem. Can i check fuse inside or it's a board who is defect ? Can i change it myself ? If yes where to find parts ? Waranty is not avaible anymore so i think i will change it by Axpert Max II 10kW but can i find better product in other brand ? Without Fan and passive heat dissipation ? What i need : 10kW, 2 MPPT and 48V battery system. Thanks for your help.

Yes you are right, just adding 1S90P to my existing pack 😀

Hi What about to add Li-Ion Battery to your pack to get 14S pack ? Each pack is self protected. It's 10.000mAh so for my pack (900Ah) i will need 90 cells like this, so 640 euros. It will be less expensive for you Is it good idea ? Thanks
