the solar panel is just to charge your inverter,if it is charging and the inverter is on it will drain the current the solar panel is supplying to the batteries,this makes it look like it is not charging ,so i advice you to switch off you inverter when charging it,get another set of batteries connected to your solar panel then charge both, let them be separated so that the new one is not in use so that when solar is out you can switch to the other set of batteries

This a possible failure of the voltage detection circuit in the inverter main board and requires the fault be identified by checking the voltage/current feed/limiter to the battery.
Once when the battery voltage has reached the threshold set up the charging should stop and then the circuit will analyse the voltage on the board to trigger the charging to be put ON.
This can be a failure of the detection circuit and if not checked can damage the battery.

I'm sorry that I can't help you, but if you're in a hurry, you can visit the Magnum website at: http://www.magnumenergy.com/Service/Servicefront.htm and try to find your model's online manual and search troubleshooting advice or you can email customer service at
email@example.com and they should at least be able to lead you in the right direction.
A few questions: Does this problem remain even when there is at least a 10+ watt load on your system? is your Magnum in a hot environment? Does your inverter feel extraordinaryily hot? Have your batteries outlived their lives? Have you cleaned all the connections? Even if they 'look' like they don't need it?
All the best to you.
