$10 a month here. Rates are the same, though.

No charge for 3-phase, I guess they figure you will be
using more juice and the bill will be larger.... he he...

| This is a theoretical question, as I am just thinking of going Gorilla
| solar and feeding some juice back into the grid.
|
| We have a 3-phase input to the meter, as we once had a large 3-phase
| 4 ton condenser. Now everything is running on single phase, just by
| tapping off one or the other of the 3 phases.
|
| The question is, would it make any difference as far as the meter goes
| and feeding juice back into the grid which phase the 220V would be fed
| back on? I think the power company man told me that we had 3 phases
| and a "stinger" phase coming into the box (I think that is grounded at
| bottom of box, not sure about that).
|
| Could you feed the juice back on any of the 3 phases and would it slow
| the meter down, or would I have to get a single phase feed to the
| house?
|
| I wonder if anyone has come across a situation like this before?
|
| Thanks,

Well if your on a single phase down stream of the meter to begin with, then its
just a matter of IF the meter will turn
backwards.
