Inverter/converter

First, I would contact Magnum Energy. They are known to be very helpful solving problems over the phone.
The generator will run but no power to anything.
Start by checking breakers on the generator. Next step would be to check the transfer switch, then on to the breaker box inside your coach.
The "no power to anything" statement.!
Do you mean just some of the 120V plugs?? Could be as simple as one of the breakers on the inverter

Thanks for the reply but there is no power to anything.The management system is showing green lights to everything.Thank you again

Had a similar problem with our Xantrex Prosine 2.0 pure sinewave inverter.

I disconnected the AC power AND the battery cables. Waited 10 minutes, reconnected, all was well. Worth a try.

Have you checked the circuit breakers on the Magnum....two on the side of the inverter.

exactly what "magnum management system" is this?

We have a magnum 2012 inverter, that error message is not in the book.
Our Energy management system is by another company though.

Thanks for all the great response when some of the snow clears I will try them.The Mangum Remote is the ME series. Thanks again Ron
