Week 25 (4/16/17-4/22/17)

4/17 – System Testing

  • Conducted the test (again) to get the AC and DC conditions when all loads are being powered. Meticulously recorded timestamps of what we did at each time.
  • DC power meter was not accurate at all so we ended up using data from the Whiz Bang
  • Conducted test to drain batteries to 20%. Loads we had plugged in were: 1 laptop charger, 1 cradlepoint, 1 iphone charge, motor blower, 3 speakers, 1 270W crock pot

4/18 – System Testing

  • Connected charge controller to internet via cradlepoint, such that its data was continually being uploaded to My Midnite
  • Began test to recharge batteries using solar panels, with no load (small cradlepoint load was compensated for in the end)
  • Began taking irradiance data by pointing meter straight up into the sky, every hour.
