You can indeed have two solar controllers on one battery bank. They will add their amps if of similar voltages.
Or you can add more solar panels to the same controller if it is "big" enough and get the same added amps.
It "depends", so need lots more picky details. If your Stealer (Dealer) will do this, then you can expect to be hosed for bug bucks compared with doing it yourself, which is not all that complicated.
So.-- If you are the least bit "handy" save your money, and ask more questions here! :)
I just read again your advice, did you mean that I could get another 100 watt panel and use my portable controller? That ai probably could do, just don't want to be on top of roof installing panels.
