The first thing I would check out is the connector for the remote wiring at the back of the control box on the left side of your gen. A pin could very well have pulled out preventing remote switch control. Also, try to start the gen with your #1 inverter. Does it start if you put the curser in the Set Gen menu under On? Does it go back off when you move the cursor back to Off? Remember after you stop the gen with the inverter to put the cursor back under the A in Auto so the inverter can at least start if on low battery.
Try those things and give us a report.
