I believe the Outback configuration will spin the meter backwards when
utility power is used to charge the batteries. I checked with former
co-workers in a utility meter department. A meter with a detent would be
the simplest way to make the meter unidirectional, but those meters are
supposedly long gone. A meter programmed to be unidirectional would
achieve what the installer wants.

We are installing a grid interactive, with battery back-up,
OutBack Radian GS8048 with 5kW of PV. Vermont has a “Solar Adder”
premium that varies from utility to utility but in this case adds
6 cents per kWh over and above net-metering (basically to come up
to a par value of 20 cents/kWh for PV production).
We need to install a gross PV production meter between the main
(utility) load center panel and the Radian inverter. We need a
meter that is not multidirectional, as we only want to count the
kWh’s that are pushed out into the grid (and not subtract what the
Radian uses from utility power to satisfy the protected loads
center when the sunlight doesn’t handle that).
Hialeah Meter offered a GE KV2CE meter that can be programmed to
do what we need for $ 260 plus $25 programming fee.
The utility will have an option, but I’m wondering what other
options others have used for this situation.
