Portable Solar Panels

[kpsf]

I have a 2003 Sportsmobile with a 100W Grape solar panel on the top of the van wired to Blue Sky Solar Boost 2512i(x)-HV and INP-Proremote charge controller and battery monitor, and 2 6 volt GPL-4CT Lifeline AGM batteries. This was done by an RV dealer. The van can only fit a 100W panel on the top. We find that this keeps us in power for about two + days but we want to have power for longer. We typically run our fridge and LED lights. We don't camp where there are hookups.


I was thinking to add a portable solar panel. I don't really know that much about solar power but I was thinking a portable panel of 100-200W would be what I need. I don't want the panel to be too heavy. Do you have any suggestions for options and the cost?


Other questions:


Could is just a hook up the portable panel to the batteries?


My understanding is that my existing battery monitor would not register or measure the input from the portable but that this is not a problem if the portable has a controller. Is that true? If so do you sell controllers with your portable panels?




Thanks
