Please review the below design for my airstream travel trailer. There is limited roof space and I was concerned about panel shading so I've opted to wire all the panels in parallel. I've considered a 24v system, but I decided against it for a few reasons:
- 24-12v dc conversion loss. The Victron reported efficiency is 92%, or 88% with their dc to dc battery charger. (Offset somewhat with 12v system losing some efficiency due to higher amps/line impedance).
- I run starlink and a lot of the trailer components including fridge, furnace, router and others off the 12v system.
- Can't run the 12v solar panels in parallel with 24v system.
