Setup for camper van

Hi

After hours of research I finally could manage to complete my setup for my camper van. I would be thankful if someone can review the setup and give me any tip to improve or correct the setup so it‘s done in a proper way

Components i used:

  • Orion Tr 12-12/30 to charge the 100Ah Lithium battery from alternator
  • MPPT 75/15 to charge the battery from my 120Wp solar panel
  • Phoenix smart charger 1+1 30A to charge/supply the system from AC
  • Phoenix 500VA inverter for AC loads
  • BatteryProtect 65A to secure DC loads
  • smallBMS to connect all remote connectors from all components

Looking good. Make sure you install a Orion-Tr Smart, not the converter.For fuses: 40A for Orion and Phoenix IP43 and 60A for the inverter are suitable values.

Thank you!


The inverter manual says that for the 500VA inverter 6mm² cross section is suitable. 60A sounds a littile bit oversized for that cable?

The datasheet and your diagram says 10mm2 hence my suggestion. Peakpower is 900W. Depending on what type of AC loads you want to power, I'd go with 10mm".

I would create a negative bus and like the positive bus return all loads and charging sources there rather than connecting everything to the vehicle chassis.

A 120 watt solar panel won't provide much in terms of charging energy. Remember that number is with intense, direct sun which you aren't going to get with a roof-mounted solar panel. For reference, I have two 180 watt panels on my travel trailer roof and get about 250 watts with full sun or about 70%. Also 6 hours of sun is a good rule of thumb. So you will probably get less than 500 watt-hours per day. You should characterize your power needs to see if solar can keep up. Add larger or more panels if needed.
