Same symptoms was described here previously. Solution unknown!
Hello all
This is the old model with VE.Bus (firmware ver. 1959132.hex)- not charger.
It has been working in standalone mode for several years, with AGM Batteries. The flashing green led (power) started flashing from one day to another. Nothing has changed during that time.
After my research and according with some sugestions, I purchased an MK-3 Interface to try a reset system or a version upgrade. Dowloaded the software and connect it. MK-3 interface is detected but the inverter is not. It shows a message “help on communication” – “Please select a communication port”. The port used is COM5 no doubts.
I checked, pin to pin, the VEBus connector RJ45 to discard a possible contact problem but all are fine.
Any ideas or someone who experienced something similar with a solution? Suggestions are welcome.
Thank you all!
