Inverter troubleshooting help

Not a big problem, but i would like to try and solve. of course, Saturday makes it impossible to reach the company!
Magnum MM series inverter with remote panel. When I press the ON switch , the screen lights up but not the on/off light. Status reads Float. Yesterday it read OFF. so I don't know if the inverter is off or on. The two inverter powered plugs are lit green. Unit is about 11 months old. Previously the green on/off switch would not always be lit, so maybe the light is malfunctioning. I am thinking it is user error.
Any suggestions? I want to use the rv when parked. But I can wait until my trip is over to have it checked by my tech.

    Disconnect from battery and let it sit for a few minutes, then reconnect. That will also do a reset. Might be prepared for a big spark.

    There is a reset on the Magnums. Check the manual on how to do it.

    If that doesn't solve the issue, find the ground for the batteries and remove the ground lug and clean the lug and the metal under it. I had an issue with a bad ground and I ended up needlessly replacing the inverter. I sent the old Magnum back to the factory and they fixed it under warranty. Note: Magnum's warranty is 2 years, but they extend it to 5 if you have a remote control panel.
