These panels are all 12V with different wattages (and physical sizes and shapes) in order to maximize the wattage I can squeeze onto my RV roof. My friend called this playing Tetris with the various panels I could find from a large number of vendors. I haven't bought any yet, but this 800W collection looks good to me. The 300W panel is 10BB technology and the others are all 9BB.
I read Will Prowse's awesome book, but I am still unclear about what is the best strategy for managing an odd collection of panels like this. I would love to pump up the voltage by connecting some panels in series, but I think that's not good for this miss-matched wattages. So I have been thinking of connecting all 4 in parallel with a single 80Amp MPPT controller. Is that a good plan? Or would 2 (lower capacity) controllers (or perhaps more than 2?) be better? Or is this whole plan crazy?
For additional context, I am currently planning two 460Ah LiFePO4 batteries (specifically the ones from LiTime). I plan to charge them from the solar of course, but also from "shore" power at campsites, and from the RV's diesel generator when needed when we boondock.
What do you experts think? Should I use this odd collection of miss-matched panels to maximize wattage? If not, I'd love to see read your suggestions about how to proceed.
Thanks!
