This is a day and morning showing the effect of what a variable speed and capacity 5 Ton AC load looks like to your houses electrical load
It's a lennox signature series 20 Seer unit that can vary the compressor speed as well as the fan speed.
The first morning bump in the left is from space heaters and coffee maker.
The middle bump is the mid day run that shuts down totally at 4PM when the electric rate goes to 49C KWH, this exhibits quite a different ramp curve than the night shift.
The bump on the far right Is the 9PM-5AM AC run to cool the whole house back down.
This exhibits very pronounced step down plateaus.
The blue curve is solar productivity but this isnt about that.
The Lennox control system is what I would call - good but not great, leaving me unable to control the system as finely as Id like with the T stat I have - maybe there is an upgrade maybe not?
