Recently upgraded 2 x phoenix 1200 inverters from Firmware version 1917141 to 1917209. One inverter upgraded without a problem. The second one starter the upgrade process and showed an error halfway through. Now this inverter is dead. No comms possible and the Red Alarm LED is permanently on. Both inverters had the same chipset (1917141 version)
Any ideas suggestions ...... much appreciated
make sure that the inverter that you are having a problem with is the ONLY one connected to the MK2 or MK3 so use a new cable and that cable is to be the only one connected. and load the VE flash make sure its the latest version of VE Flash
redo the com port connection turn on the inverter and it should connect if not then using the same cable does it connect ok to the first inverter ok still
try the secound RJ45 connector on the inverter
Try a different computer ( I sugest this as a last resort I dought it will help but try)
If the below does not help then [please send some screen shots of each step and discribe your issue and procedure as you go
Managed to resolve the problem. I used an older version of the VEflash. Upgraded without a problem.
Thanks for taking time to answer.
Thanks for reporting back. Glad to hear you resolved it.
Can you say which version failed and which one succeeded?
