Quattro 48/8000/110 s/n HQ17426YBN5 CHIPSET 6955161.HEX
using VE flash attempted to upgrade firmware to 6955476. The uploaded appeared to work. after the upgrade quattro did not turn on.
I have tried firmwares 69552xx and also 6955161 as above the upgrade appears to work but inverter fails to turn on.
I have powered the entire system down after each firm ware update but inverter fails to turn on
After upgrading to 6955476 was able to communicate with VICTRONCONNECT but still unable to turn inverter on.
PROBLEM SOLVED
I connected to the inverter with VICTRONCONNECT and did a firm ware upgrade with that. the firmware loaded was 6955475 and the inverter is now running.
