Looking for advice: converter/inverter brands, models etc.?

Thanks for all of the help everyone... I just ordered the charge wizard from best converters, should be here soon. I did think of another question though. I also just ordered a Sunsaver 6 to connect my 50watt solar panel. How will that work with the 9100 converter & Charge wizard when I'm plugged into shore power? With regard to will both be trying to charge / over charge my batteries?

Thanks.
