Electricity

 

The electricity to the house will come from Solar PV panels in the rooflight and 240V AC from the grid.
The house will have both a 240V AC distribution as well as a high power 48V DC distribution system.

48V DC System

The DC system has these sources

  1. Two 240V AC Power supplies each supplying up to 2Kw
  2. Solar voltaic panels >1Kw
  3. Large Lithium Iron Phosphate Battery bank >10Kwh

The power is distributed with large Aluminium bus bars running through the hall floor space with copper cable taps to each room.

The DC system mainly powers the LED lighting throughout the house.
