On Bluetti’s website it states that roof solar arrays are only applicable with AC300 systems (at least as compared to the AC200 MAX). It also says that solar expansion module is sold separately.
I don’t get it! I bought six 100 Watt Renogy rigid solar panels. What difference does it make if I put them on my house roof OR make them portable so I can take them out of storage and put them out on the ground on an “as-needed-basis” (i.e., power outage situations)?
And what is a “solar expansion module” and how much does it cost? Why can’t the solar panels simply be hooked directly into the AC300? Any help will be truly appreciated.
