We have a PV system with a PV inverter SMA X15-50 + Cerbo and RS450/200 + inverters Multiplus.
We follow all instruction and we test all according to the manuals.
Ping over LAN - is OK
PuTTY connection port 22 ot Cerbo - OK
telnet connection from Cerbo to SMA port 502 - SMA return connected.
The Cerbo can not find SMA inverter automatically and manual. No data no info.
We test with Cerbo firmware 3.10-8 from yesterday 11-June-23 and no changes.
With kind regards.
