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

I was using Modbus to collect some data and generate some nice graphs. I had some errors in the current measurements until i fixed it in the evening of August 24th. Screencapture-10-10-0-29-3000-d-qBcRzeOZk-pv-2019-09-08-13 16 57.png
