Quattro 12/5000 does not charge anymore from generator

Until yesterday all was working fine. No error lights on the Quattro. Since today of we want to charge by generator, the Quattro stops charging. Quattro is first switched to charging mode from gender and then switched off again (we can hear the clicks). Generator is working fine, that is tested. All other functions working fine (solar comes in, Quattro is inverting). Both BMV and Venus work well and show all other functions. Does somebody have an idea what we can do?

If you have an MK3 dongle, connect to the quattro and check the quality of the output voltage and frequency. Many at times, the generator looks good on other appliances that are not connected to the quattro..... but if the quattro is getting inadequate voltage or unbalanced frequency this can happen. Secondly, swap the working AC input to where does not work and see before concluding if the relay and contactor to the leg is bad.
