Thanks so much for the support. The inverter was new and I sent it back to the seller for service. They fixed it for me by telling me that it was the first time something like this had happened or that "I found the signal cable that manages the front button disconnected" Thanks again

After several tests I have seen that the on / off button has no influence on the inverter. I tried to put the HS diaplay on the SL but the result is the same. I think it's some internal link. Can you give me instructions on how to force the function of the key? Thank you

If your switch is definitely on, as others have said, it could be faulty, or there is a break in the cable from the removable display to the inverter, or something is faulty in the inverter itself. *I have inverted the displays and the result is the same. That is, that Axpert does not power loads through the conversion from DC If you remove PV and AC-in from the slave, does it go dark after 30 seconds? *I will do this test If you isolate the master and switch it off, does the slave then power the loads? *I will do this test. I tried to turn off the Master switch, but the result hasn't changed

The slave inverter is acting like it is switched off. This can be caused by: It IS switched off. The switch is faulty. The inverter is faulty. 1 seems very unlikely, but easily rectified.😀 The switch is on. In fact, when it switches to mains power, the output is active 2 is easily checked by swopping the 2 Remote Display Units. The switch is a purely mechanical pushbutton - if that is faulty it is easily replaced. Test already performed, the result is the same. 3 seems unlikely given that there are no error codes. Perhaps @Coulomb may have some insights? What do you mean by "some insights?"

Good evening, I searched the forum but couldn't find any place that can help me. I have recently installed 2 inverters, Axpert king 5k, in parallel. The connections are all correct but I have this peculiarity. One inverter, in this case the HS, converts from DC to AC and sends it to the output while the other, the SL, does not carry out the conversion and only outputs when the bypass occurs. In practice, the inverter powers the output only with the utility and never with batteries / panels. I attach some photos. I hope you can help me.
