CCCamp 2019 - Obri's Setup

About two months before the camp i decided to replaclace the two allmost dead 95Ah lead acid batteries in my campervan with new LiFeYPO4 cells. I was able to save about 25kg of weight with this upgrade.

The only thing that was powered with diesel power during the camp was a small 16 port switch. I had enough PV power to run all stuff i needed during the camp.

Upgrades/Changes/Notes for the next camp

• The Fuji F-wave where connected to the same relays as the inverter, i had to switch it off manually each evening to save some power.
• My android car stereo does user a lot of power when it is switched on
• The Fuji F-wave panels did not produce a lot of power.
• Add more sensors!
• Install more 12V Outlets
• Switch to Speacon connectors for all 12V Outlets
• I should replace my absorber fridge with a compressor model
• Clean up the massive mess in the battery box.
• I need to finish my custom LED PCBs for all lights in the campervan.
  • The campervan manufacturer did install LED lights that where made for exactly 12V
