August 27, 20251 yr Author I made an IC, completely erased the EEPROM, and re-soldered it. The inverter worked, but after two months, the same fault returned.

August 28, 20251 yr Author My friend, I erased the EEPROM chip, but after 3 months the same error came back. E90

Voltronic got sick of this and put traps in the firmware to cause fault code 90 to come up after 60 days of running, if it detects that it's running in a clone.How long the inverter is running as a clone is stored in the EEPROM. That's why erasing the EEPROM gives it another 60 days. But you also lose all your settings and calibrations.
