Hey everyone! I'm working on a solar setup for my Skoolie build and have most of the components sorted out (all from Victron, except the panels and rails). Unfortunately, the rails are still backordered, so I haven't been able to install everything yet. I just got invited on a summer road trip in my old camper, and since some campgrounds won't have power, I'm considering using my existing gear temporarily.
I can fit one solar panel in the back of my truck, but I've got a 48V system, and each panel only outputs around 31V at maximum. I'd rather not install two panels on my camper, especially for just a month or two of usage. I've heard about using boost converters, but I've seen mixed opinions about whether they work properly with MPPTs. Any suggestions on safely doubling my panel voltage without risking my equipment, which is worth about $5k?

What's your battery voltage and which MPPT are you using? Knowing this will really help, as it affects how you can configure everything. Just a heads up, though, if you have a Victron SmartSolar MPPT 150/70 and a 51.2V battery from Li Time—your panel with 31V Vmp and 12.9A Imp should work as long as you set everything correctly.
You might want to check out the BougeRV MPPT; they actually have models that can boost voltage, which sounds like it would fit your needs perfectly. A buck converter isn't ideal for this situation, so focus on that boost option!
