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 12V
  • I should replace my absorber fridge with a compressor model
