Hi,
So we're building van that will be used for year around living, mostly in warmer climates. I've been doing a lot of research for the solar system and landed on using the DCC50S 12V 50A DC-DC On-Board Battery Charger with MPPT from Renogy, as it seems to be an easily installed and intuitive option for someone who doesn't have that much experience.
However, I've seen in several places that it's recommended to use this with a solar array of max. 400W (instead of the rated max. 660W) and understand that this is due to the low max. input solar voltage of 25V of the Renogy, which requires you to install your panels in parallell and have high amperage. The issue is that I'm not sure 400W will fully cover our need, and as we'll be working remotely and I really want to make sure we have enough power. It's not that big of a difference, but bumping it up to 500W-550W would probably be preferable. So, my question is really related to that. What would it take to be able to connect say 3 x 175W panels to the battery charger? Thicker wires and adapters? Would it be worth it, or should I look into getting an MPPT and a charger separately instead?
Thanks a lot,
M
