Digital inputs 0--4 meaning/assignment as of 2007-11:
- True/1 if battery voltage indicates good charge and currently charging.
- Not assigned.
- True/1 if input to DC-DC converter is good (no low-voltage disconnect).
- True/1 if output from the wind turbine is available.
- Never assigned, so should always be false/0.
Input 1 until 2008-06-24:
- True/1 if output of DC-DC converter is good (laptop off-grid).

Equipment Change/Upgrade Notes
These should be read alongside the numbers above:
- 2008-07-01 (~0900UTC) new laptop/server internal battery fitted.
- 2008-06-26 Input1 NOW UNALLOCATED; no longer 'DC-DC converter output OK'. Current allocation/meaning of inputs:
- "Battery Voltage High" (Input0) reports essentially when the battery is full and still charging, so the system should dump some energy.
- "LVD Output On" (Input2) reports when the battery is fairly full and is running the server/laptop.
- "Wind Power" (Input3) reports when a turbine is turning, though not necessarily generating useful energy.
- 2008-06-24 laptop internal battery died so 2008-06-26 replaced mains/off-grid switchover mechanism with an 'instant' diode-based scheme.
- 2008-06-05 (~1600UTC) rewiring to reduce impedance and improve behaviour under heavy load.
- 2008-06-01 (~1700UTC) addition of 2x12Wp amorphous panels (Maplin N32CX, TopRay TPS-102-12) on east-facing near-flat porch roof, bringing off-grid total to ~120Wp.
- 2008-05-24 (~1200UTC) addition of 12Wp amorphous panel (Maplin N32CX, TopRay TPS-102-12) on east-facing near-flat porch roof (in place of 13Wp test panel).
- 2008-05-24 (~0700UTC) addition of tiny 2.4Wp (Maplin N59FU, Nikkai) amorphous panel on west-facing near-flat shed roof.
- 2008-05-10 (~1430UTC) to 2008-05-24 (~1200UTC): temporary/intermittent addition of 13Wp horizontal PV on east side of house to catch morning sun and extend off-grid period for server.
- 2008-04-17 (~0800UTC) to 2008-04-23 (~1100UTC): major rewiring.
- 2008-04-10 (~2000UTC): disconnection of 2x1W turbines for wiring rearrangement.
- 2007-12-01 (~1600UTC): installation and connection of MotorWind 8-turbine device.
