I am looking at using the same setup for my solar panels and inverter as you have. What is your opinion of the flex panels and inverter? Are the charge controller and remote also something you would recommend? I am just starting to look into this. Do you have 6 volt or 12 volt batteries. I have the 28 and not the 30 but mine came with 6 v batteries. I was reading somewhere to use 24 v panels and not the 12v.
