Why I can not select " And"/" Or" in my adapter G2 settings?

Kindly make sure all the wiring is correct and adapter box can communicate with inverter. Then make there is battery connected to your inverter, also the battery should be solax lithum battery. What’s more, please make sure the "export control" value in your inverter setting is not 0. Also please be advised that the switched off signal has priority if both the "Signal ON" condition and the "Signal OFF" condition are met. If you still have further issue, kindly contact solax support for more help.
