Sorry, but this is a very naive question....
When SMB-TX did electrical work on my homebrew in 2009, they added a 4D AGM battery ($495) under the van step, as they do with the RB-50 layout.
Now that I'm thinking about adding solar, I need to know the capacity of the battery. I can't find it on my receipt, nor can I find it on the SMB website.
Can anyone help?
Also, once the capacity is established, how do I figure out the correct size of solar panel to match the battery?
