I have 150AH, 12V, 2 batteries Group24 (older batteries). I'm trying to figure out the best solution to improve my current AH availability and allow me to go longer between generator runs since I don't have solar.
Over the next 12 months, we will be boon docking MORE in the southwest and west...therefore, before I head out, I want to replace my battery configuration and/or add solar to help.
This is, more-less, what you should've started from. Posting your current setup. Also, if there is any room for expanding the battery bank. Also, your goals - i.e. how long you plan to boondock. "More" is not very informative. Also - whether a generator is going to be in the picture at all. Also - your daily energy needs, i.e. energy audit. This is perhaps the very 1st step that you should take.
Answering your question - my solar is 490W, made (of course) of 24V panels. It is not practical to have solar larger than 300W made of 12V panels (if this is what you meant by "panel type").
Portable solar has its limitations, this is a separate topic, but if you are heading that way, you have to lower your energy needs. This is what I meant by saying that energy needs have to be of the "right size" for your charging method.
Also, - again a separate topic - running 200AH bank flat overnight with only one 12V fan running doesn't sound normal.
