A question about : Owl Intuition Solar PV >>> Type 2 >>> wiring

The Owl might may meet my needs. Can anyone answer these questions please?

[1] Wiring

/

Sensor 1 and Sensor 2 appear to be on the same wire. Does the distance apart matter? Can the sensors touch each other other?

[2] Data

Does the Owl web based system include a historian that retains past data?

Best answers:

  • After extensive research I've come up with very little, but it is an interesting conundrum.
    I didn't see anything to suggest that the proximity of the clamps would be an issue.
    Clamp 1 is purely measuring generation. Clamp 2 in conjunction with the grid clamp is working out import/export & therefore solar use. It appears that the Owl was originally designed for type 1 installations & the Y cable was added later to encompass type 2 (that's just hypothesis).
    Removing the outer sheaf from the inverter cable (usually 2.5 or 6mm T&E) might be an issue for someone planning on fitting it themselves.
    Sorry I can't be much help.
  • Your assumptions Sterling and Nicks research are correct.
    I'm no longer using my owl, but yes, doesn't matter about distance between clamps.
    If you are not comfortable strippng the outer casing back to expose the live and neutral cables (Brown and blue) then get a sparky, but careful pruning with a not too sharp knife does the job fine.
    Quite useful really as you need to do the same for a Wattson.
    Be aware though that if you have a diverter (to immersion element) then neither the owl nor the Wattson produce reliable figures...
    My personal experience anyway!
