Here is a summary of the electrical system:
> 4 - 100 watt solar panels
> 2 - 100 amp-hour LiFePO4 batteries
> 2000 watt inverter
> 12V 130L fridge
> Webasto Petro Heater
> 2.6 gal HW heater with 12 volt heating element
- The hot water is automatically energized when the battery capacity hits 100%, so most of the time it is heated with "excessive solar" power.
