I misunderstood the question the two options I listed are battery systems.
What I should have suggested as a solution was the Enphase microinverter
system with the Zero Export profile and Production CTs on the service to
the panel. That will do Zero Export so that all the power produced is self

Hi Wes and everyone else.
I’ve heard from Enphase and Fronius offsite and indeed its quite possible to do
“self consumption”. Both Enphase and Fronius need some additional hardware but
thats to be expected and pretty minor really.
SMA and SE both are supposed to do it but I didn’t pursue
HI Jay,
The Fronius line, primo or symo have that capability. You need the smart meter
to measure current flow at point of interconnection. The tricky bit is what
happens when a big load suddenly turns off. There will always be a small flow
of energy across the meter for a second or two while

The SolarEdge HD Wave line with their accompanying electricity meter (which
uses CTs to make sure that export does not take place upstream of the CTs)
should work fine for what you suggest.

Hi Chris,
So it doesn’t sound like what I’m after.
I’m looking for a GT WO batteries hooked to the main panel just like normal
but having communication from the main ( could be reading smart meter or using
sensors) to allow power to be consumed in the house but no export to the grid

Both SolarEdge and the Enphase IQ7 should be capable of doing zero export
with or without storage.

Enphase, Solar-Edge, Pika, and I believe now SMA. You can check HECO advanced
inverters list under CSS program which lists all compliant inverters.

I think you do need either a battery or AC source to start up the inverter
in the morning. It's also possible that if it is overloaded and shuts down
it might not restart. It will not start from PV alone.

Jay,
My understanding is that the Outback SkyBox is capable of supplying power
to AC loads (what they call “micro grid”) without needing grid input or a
DC storage system. Kind of like the SMA SunnyBoy secure power supply, only
on a larger scale. However, depending on the electrical demands of
are there any products out there that can do a grid tie w/o batteries but no
sell back to the
grid?
Thx
