Hi Daniel,
I changed +/- and were successful in getting response from the inverter.
BUT now I getting a strange behavior of the W4K. It restarts every approximately every 3-4h. It is definitely related to the RS485 connection.
Any idea why? I have no resistor oder termination in the RS485 bus and just 2 wires D+/D- connected. Also just the W4K and the Goodwe inverter are on the BUS.
Many thanks for your help!
Best Regards
Steffen
