You have to have a charge controller to make sure you do not over charge the battery. The inverter relies on the batteries to supply any additional current/power the solar panels can not.
As Doug said - Don't remove the converter unless the charge controller also has the capability to run off shore power. I might add that the converter in the TM also incorporates all the fuses and breakers for the TM. Simply removing the converter opens a whole new can of worms, so to speak, since now the systems have no circuit protection. I'm pretty sure (more like absolutely sure) that those who have added solar power have not removed the converter. How would you run the air conditioning, microwave, hair dryer, etc.? All those larger appliances draw more than the small batteries on the TM can provide and solar takes a long time to recharge those batteries even in direct sunlight in Arizona in the summertime!
