I am running into issue properly sizing my MPPT for my solar panel.....I have one LG355N1C -V5 on my van and victron site is stating MPPT 100/30 however www.explorist.life is stating 100/50. Not sure what to choose? Also what would be proper size disconnect/isolator for my panel. Thank you!

We need to know your battery voltage

If it's 12v then the Victron 100/30 will work

If your voltage is 24v, then an even smaller controller will work like 75/15

For your low voltage, and current any of those cheap dc breakers on amazon will be fine. I'm assuming you're using PV cable? If so that should be rated for 30a and you'll never overload it with that one panel.

Does any anyone know what might be causing my Solar Charge Controller 100/30 to disappear from view on the Victron Connect app each morning?
