It is that simple. Outback and xantrex offer PV/battery primary, grid
optional, and PV/grid primary, PV/battery backup modes.  In the pv/
battery primary role, the idea is that power is only taken from the
grid if the batteries are low due to low sun conditions, and only long
enough to bring the batteries up to a specific SOC. Outback calls it
their HBX mode.

Finally found a human at Xantrex [in Vancouver] who was helpful, but could
not find any references to 3ph 208 Wye systems that they offer. I sent her a
note to forward to apps engineers.

We want grid-tie such that ONLY PV output is sold,, never battery->grid.
Interestingly, PGE swears upsidedown and sidewise that they NEVER allow
a grid-tie with batteries attached; while both Xantrex and Outback say theirs
have same; and one, ISTM Outback, said that's how they think battery->grid,
with PV being battery recharge.

I am told in Ontario they do not allow systems to connect and bill / credit
on their MicroFIT programme with batteries. However they are paying 80.2
cents / kWh and it becomes obvious, quite soon, why they wouldn't want to
pay for regurgitated grid power, time shifted.

I ask "Why not" but the Hydro company isn't the one behind the big payout.
It's the gov. trying to promote overpriced PV systems to ge them accepted
into our culture.

Why even tell the power company what you plan to do?
They will only pay you some unreal wholesale price for
your PV power.  Guerilla solar is the way to go.  You
get FULL PRICE for your power, not a paltry fraction.

And, don't say anything about safety, it's no issue with
the new inverters.

This all depends where you are!


$.802/kWh here!!
