<br>
Here's a metering conundrum for you.<br>
<br>
I have a client with a dual stacked Outback 3648 inverter panel
and a PV array. He has been off-grid for years, but he is now
going on-grid. He is getting the Outbacks rebuilt at the factory
to be grid tie compatible.<br>
<br>
As per our local requirements, he needs a meter to read just the
output of the inverter. The problem is that he has the whole house
on the inverters, not just a vital loads panel. He wants to keep
it that way. That gives him two separate outputs, "AC Out" to the
main breaker panel and "AC In(teractive)" to the grid connection.
If he just puts a meter on the AC In line, he will lose track of
the inverter output that goes to power the house, and he'll get
his output reduced by any grid-based charging he does.<br>
<br>
There is a "green tag" method of wiring the meter to avoid this,
but it is designed for two single-leg 120VAC outputs and the
stacked Outbacks are putting out 240VAC on two legs.<br>
<br>
Aside from dropping $600 on an e-Gauge, is there any way to get
around this?<br>
<br>
Many thanks,<br>
<br>
