  1. Thank you Columb for your help. I however failed to repair the inverter BUT I was contacted by Reinier who lives in Wolmaransstad and I live in Cape town. he told me what to do to repair the inverter The Problem was that I didn't replace all the components that he asked me to replace. Hence the problem wasn't resolved. He then offered to pay for the courier service from my home and back as a favour to me. I trusted that he will be honest enough to fix and return the inverter. I must say after chatting to Reinier it restored my faith that there are good honest ppl still left in this world. And extremely knowledgeable. He knows these inverters inside out. I promise anyone who listens to Reiniers Problem solving tips will save you a lot of time and money. He had the inverter fixed in 20 minutes after it landed on his table and sent me proof that it was working..even replaced those SMDs that i was advised to replace but those SMDs wasnt the problem. I dont think it will be fair for me to give away his trade secrets lol. I will let him decide if he wants to or not .lol I'm not sure if Reinier is available to help but my experience with Reinier and his extreme honesty knowledge and kind heart really blew me away. I just wanted to tell my story. Bless your soul for your kindness Reinier
  2. Good day I live in Cape town and I'm looking for a charge controller board for my 5kva inverter. Does anyone know where I can get one. Thanks
  3. Where do you live? I'm in Cape town South Africa
  4. Is it worth taking out the others that measures 330k ohms in line?
  5. Hi Columb I took out R130 and found it to also be 330k ohms
  6. Hello Columb Yes the resistors measured in  kΩ I took the R140 out of the circuit and it measured 330 kΩ do you think its necessary to remove other resistors and measure or rather look elsewhere for a Problem?
  7. Hi Columb I found a discrepancy in the R130 and R140 resistors R130 measures 0.226 R140 measures. 067 Yet both resistors are the same. Could this mean a Problem with resistors? Also the board is not dusty..it seems like the coating has faded.
  8. I need to locate the circuit to determine if resistors are blown or faulty. Can it be just a software Problem Columb?
  9. This is the underside of the board..Columb I'm lost lol
  10. Maybe a circuit diagram will help if you have one please
  11. Yes its Mks. Will the resistors be under the board? Because theres something preventing the board from lifting up after I removed most of the screws.
  12. Hi Columb My main board seems different from the pic you sent to me. Even the resistors are numbered different. See the picture attached. I'm not sure if the 4 resistors are the voltage divider circuit. Please help
  13. Thank you Columb Can you please send me a link if you have or know of.. how to disassemble axpert inverter. And yes 145V max controller. Thank you very much Columb. I'm going to attempt to repair myself.
  14. Voltage from PV Good Day My inverter stated to act up this Morning. I noticed that the inverter is displaying much higher voltage than what the PV is pushing out. I then connected just 1 panel which is 48 volts I noticed Inverter displays around 80..if I connect 2 panels the inverter solar voltage goes over the 145Volts and cuts out the solar charging.. I measured the voltage from solar with multi meter and its not the same as what the inverter is displaying. Please help...
