Hey everyone! I'm diving into solar for my van and wanted to share my planned setup to get your thoughts. I'm considering starting with 2 200W solar panels connected in parallel, paired with 2 100Ah LiFePO4 batteries also in parallel. For the solar charge controller, I'm looking at the Victron MPPT 100V 30A model, but I'm wondering if the 100V 50A would be a better option for future upgrades. My ultimate goal is to have 800W of solar and 400Ah of batteries. How does that sound? I found a similar setup where the response was positive, but I'd love to hear more insights! Also, I noticed suggestions about going with a 50A controller for expansion potential; given that my 200W panels will produce around 27.2A, do you think the 50A option is safe?

You might want to wire your two panels in series to simplify the connections—just make sure not to exceed 100V. Also, don’t forget to include fuses or breakers for safety!
Thanks for the tip! I’m going to update my post because I’m concerned about possible shading issues if they're in series on the van.
