  1. This can't be flashed via jtag if briked becouse is password protected
  2. If memory damaget can't write serial number
  3. i test all eeproms chips from same control board with problem: i can read data but i cand write, i try erase chip but data still there, chips are broken. i place new chip with data from bad chip, remake serial and inverter work very good. will see in 60-90 days if problem is. Also, monitoring software no report anymore "eeprom fault"!
  4. Serial number can be changed ! Settings also. also i read chips 24256, i put backup here. Use only memory 24256, or M24C256 32k 8Kw_good.bin 11kw_good.bin
  5. Hi again, today I changed the memories between 2 control boards and it seems that the cause of F11 is the memory chips . Problem solved!
  6. Yes, is normaly!, All inverters have that voltage there, at the PV input, it is normal, it is not a problem if it does not exceed the minimum accepted by the MPPT, in our case 90V. I saw that voltage in all inverters, with small differences, between 25V-45V. Also, i have now in service 3 inverter 11kw all with fault F11, problem is from CONTROL BOARD. They were installed in three-phase. will try to change memory on CB (Control Board)
  7. NOT TESTED!!, I try to SML II but not accepted. VMII_Ver31.06_reflash_SN92931807100085.7z
  8. Any news? It's posible to read bootloader from good DSP from inverter? I think, if buy new DSP (chip only) if I can write firmware from hex and bootloader from good DSP ?
  9. First, try update firmware MCU, if not work need to change communication board near the display!
  10. This is full firmware with bootloader. Write with jtag. Firmware for serial like U2 not exist for VE series
