We wanted to build a DC microgrid at CCCamp19, but never fully got around to it. So we'll keep on trying in our lab, for the next camp and other events.

Gear we have built so far

Hacks and other related information

Name

Our gear at CCCamp19
  • Forty Eight Grid
  • Team Forty Eight

List of recommended devices


Power Out Boxes

48V-> 24/12/5V

  • DC sockets
  • Car sockets
  • USB
  • Switches + Fuses
    • What kind of fuse?
  • Volt/Amp Measurment - "Battery computer" -> Stats via LoRaWAN?

USB Charging Station

I have two 48V->5V DCDC converters (Product page, datasheet), which we could used tu build USB charging stations for powerbanks etc.

  • USB "power sensing" via data pins: [2], [3], [4]

Power In Boxes

12/24V -> 48V

  • Schottky Diode
  • Fuse / Currentlimiting
  • Batterymonitor / Datalogging -> LoRaWAN?
  • Auto-Disable with Under/Overvoltage

Connectors

  • SELV [5] [6] [7]
  • Speakon
  • XT60
  • XLR-4
  • Car lighter plugs
  • DC barrel plugs

Further Reading

Ideas

Biolite "MicroGrid"

Biolite has a "base station" with a battery and connected lights to it (Core77 blog post). We could build a similar station and connect other stuff to it.

  • Connection between lights via some common cable we all have - RJ45? passive PoE? To remain compatible with a bunch of other gear out there...
