Hi @Coulomb just want to let you know, I received replacement of remote display, and its working!! woohooo. so looks like the display was faulty, the supplier said they got a another unit that got an 32 error code. Thank you for your support to help me

Hi @CoulombI have changed it,I used 3 differents pc's the one pc still got an RS232 port,so I tried it without the converter,com port opened,after 30 seconds its says closed port and then connect failed,I literally tried everything,I phoned the supplier this morning,they are going to send me a new remote display. hopefully it will work then 🙏

Thank you so much for your reply,as I see you are the expert here on the firmware The inverter is working,it charge the batteries with solar,like normal,but now I want to try to update the firmware again,and click on MCU but after a few seconds it said "COM1 was opened!" and then it says connect failed,I even try an windows 7 notebook,sounds like it does not allowed me to connect anymore,I also tried a few different cables🙄

Hi guys I really need some help The inverter's mppt board failed about a week ago and after a few switch off's and turn back on's I got a 32 error code on the remote dispay (communications) anyway long story short,I send the inverter back to mustek and they replaced the mppt board after all the inverter was still under warranty,so after few days of wait and strugling with couriers I got the inverter back,mppt is working and the inverter is starting up correctly. the fricking 32 error code is still there so I have no display that is giving me any information. Reading posts and browsing through the forum I came across on reflashing and starting to try and reflash remote display with 02.49 and I make a mistake and click on DSP and now the remote display is dead and only button that works is the power button. Did I break my remote display? 😭

So sorry I have mistaken your E9 with an 09,apologies. Lithium battery does not need equalization and you should turn it off,battery equalization is only use for lead-acid type batteries

Hi,when did this happend? does your inverter perform normally? there is no electrical burn smell? when I check on my research you may blown a diode if I am not mistaken

Hey guys,so I was wondering if there is any expert (or Axpert...lol! ) electrical guys out there,so this was my previous inverter,I cannot remember what happend. it does not turn on,no LED or LCD display. As I have done some test and doing some research,the inverter receives power from AC and batteries,just little soft power noise on the mainboard. So I found a service manual on the net and it point me to the S.P.S (Switch Power Supply) so I found the area on the main board where the S.P.S is,I will attached 2x photos. My Question,Have any of you guys run in the same problem with the axpert inverters? and what component is that I need to replace? Its Lockdown and I am looking for something to do😋 I got an Axpert King 5kva and happy as can be,but would like to fix this one I have fixed some board issues like LCD screens,etc before

@Youda Okay tested with multimeter and so on,my pinout is not the same,so no2 that suppose to be green is Red,pinout 3 is green,tested it with multimeter again,and so I connected it now 2min ago,freaking awesome! thanx for all your help,I really do appreciate!

@Youda Sorry to bother you again,so I find good quality RS232 to USB converter (UNITEK) Just want to make sure the pinout to the RJ11 is correct,that yellow wire that show not in used,pin 1,does it need to be connect? because I left it out,but still no coms on battery view

Thanx @Youda I have looked at your system...man that is good work,well done!! I have the same blue cable that is on that picture,its standard Cisco Com cable to config Cisco Routers,got actually a few of them,going to try this.

@YoudaDamn!! I read that the usb cable that I ordered just need to crimp the RJ11 connector,well waisted R200 😫 I got a USB to RS232 converter and I got RS232 to RJ45 cable,so I can just cut of the RJ45 connector and crimp Rj11 and then connect the RS232 male and female together. @hancock possible you can send a photo of the RJ11 side,just need to see how many wires is crimp on the RJ11 and what nr pin sorry for all the hassle.

Many Thanx,I found the correct usb cable,I just need to figured/find the correct diagram for console reading then I can crimp the RJ11 connector

I am in IT so it cannot be so difficult,thanx it will be great!!!

Good day Gents, I am looking for pylontech USB cable for RPI for ICC software, I have spoke to manie,seems its still out of stock,I have also send an email to Riaan from diversified but not yet any response. Is there someone that maybe got one spare laying around? pretty please🙄
