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"!

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

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!

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)

NOT TESTED!!, I try to SML II but not accepted. VMII_Ver31.06_reflash_SN92931807100085.7z

is working?

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 ?

First, try update firmware MCU, if not work need to change communication board near the display! -
no, sorry

This is full firmware with bootloader. Write with jtag. Firmware for serial like U2 not exist for VE series
