Earth Notes: Historic Off-Grid Stats via K8055 (2007 to 2014)

Updated 2019-09-26 05:52 GMT.
Historic power-management system statistics for the off-grid system storage via K8055.
Historic off-grid data as logged via the K8055 USB I/O board.

Previous K8055-measured off-grid storage parameters from 2007-10 to 2014-07 when the k8055/SheevaPlug were decommissioned. K8055 log format: YYYY MM DD HHMM timestamp;digital;analog1;analog2;counter1;counter2.

Digital inputs 0--4 meaning/assigment as of 2007-11:

  1. True/1 if battery voltage indicates good charge and currently charging.
  2. Not assigned.
  3. True/1 if input to DC-DC converter is good (no low-voltage disconnect).
  4. True/1 if output from the wind turbine is available.
  5. Never assigned, so should always be false/0.

Input 1 until 2008-06-24:

  1. True/1 if output of DC-DC converter is good (laptop off-grid).
