sorry, the end of that cable is now soldered to a DB9 connector as screenshot below...

Yes, the cable is plugged into the comms board of the inverter...there is 11,13Vdc measured across pins 7&8 Wow, I can't believe this emanated from a failed firmware upgrade....

Hi Coulomb It's definitely not working after shorting pins 7&8 (The other end of the cable is not connected to anything and not shorting between cables to be used (cable is ready for the DB9 connector once I have it on hand)- no response from the inverter at all - completely dead. What are the next steps after this failed firmware upgrade?

Noted, I tried this with no effect though. The inverter did not restart. Checked battery voltage at the Inverter input terminals - correct - checked the inverter 150Amp fuse - all ok.

Thank you Coulomb....I haven't got around to this yet as I've searched for a female DB9 which I thought I had but to no avail...will be passing by an electronic store tomorrow and will purchase at least 2 x male and 2 x female for future ..., so for clarity, would the inverter start up just be shorting 5&6 out together without the RS232 connection to the PC, or is the necessary voltage supplied by the RS232 PC connection?

Coulomb, I've unzipped again and placed them in separate folders, named accordingly. I'm in a rut as the display wont power up due to the inverter not powering up. I there a way around powering the inverter without the display? Failing this, I will have no choice but to take the display in to reflash the Eeprom in order to get the inverter powered up.

Hi Coulumb Thank you for your assistance thus far. I've attached 2 x screenshots of the relevant MCU folder with the associated reflash tool that displays the DSP upgrade option as well as the CPU folder with relevant files. I've been told by someone else that I would need to take the brick display in to reflash the Eeprom. The Inverter does not power up at all, no lights, no sound - nothing - completely dead. Is there another way to restart? (Maybe by physically disconnecting everything and rebooting from the battery alone? (I doubt this but am clutching at straws now).

Hi No, definitely on 2 x fully charged Revov batteries.

Hello everyone...I'm really in need of advice. Received the relevant MCU & CPU firmware from the installer and attempted to update myself using the USB to RS232 method, which seems relatively simple. Isolated Grid input / Isolated Load output and switched off battery, connected USB to RS232 cable to Inverter - opened the reflash tool - selected the update file. See image attached. LCD Panel went blank after this and inverter completely dead - no screen, no lights - nothing. The firmware versions shared were as below MCU (02.83) CPU V41.17

Hi Nitesh....are you using the Solar assistant app as an alternative to Watchmanager? Via Bluetooth only? I also have the Kodak OG3.24 without WiFi and am looking for an App as well as an RS232 to wi-fi adapter... TIA

Hi everyone...Is there an alternative Bluetooth App other than Watchmanager for Kodak OG.3.24 Inverter? The Watchmanager App wont install on my Android because it says its meant for an older version of Android. This Kodak does not support wifi, only RS232 and I will seek a RS232 to wifi converter, but for now I want to use the Bluetooth functionality. I can pair my phone, but its useless without an App.

which App did you use? The Watchmanager only works on older versions of Android and I have the same problem using a Kodak OG3.24 inverter.
