this thing I am testing is my furnace which I also changed the fan On time from On for some time after it cycled to turning off within 1 min of furnace shutdown. which I think has saved me some of that money.  

But the other reason to tear my wall apart was to get a better idea of the capacity of Each of my 8 packs vs it's calculated capacity from the individual cells testing.  and oddly it's lower than the calc.  I thought it would be higher.  as I am testing at a lower current per cell than when i tested each cell.  

And I also got another box in the mail of Packs from another member on here (Headrc I think) and upping my pack count to 77 at a wopping estimated Capacity of 5.19KwH   WOOT!!!!

But some of this will be going out to camp and the rest will stay here and run my fridge and stuff.    

Next on my purchase list is Cheap Solar to help charge the Batts to further reduce my cost of Power.     But Since this is only playing and I'm not trying to go OFF Grid at this house.  this is the Learning for our eventual retirement house in the Woods totally Off Grid.

Once I get the house Powerwall back up and running I'll take some more pics

Hey jdeadman,

I would be interested in how you have your switch over / timer circuit setup.
I to am in Ontario with the same rates.

Also, how did you score 285lbs of cells?  Perhaps I could score some in the same way in my area?  (if you would care to share through PM)
A member of one of the facebook groups was getting rid of his cells as he was going to go a different direction. He was 5 hours from me in the states. Super great guy just not able to Do the power wall.

I had been using an automotive timer to turn on the UPS / charger AC input during Off peak. But with the new wall that is going to be much larger I will be going the MPT solar route I think with one of the LV series that can be paralleled together and it has a solar charger, and grid charging built in just need to program a timer within the unit for that charging.

I will be looking into that more in another thread i am starting soon.
