If the inverter(s) provided energy production data, you would already
have all the information you really need. Sounds like it must not. So,
if you are looking for something that is relative inexpensive and
reasonably accurate, but not revenue grade, you could use an Efergy True
Power meter <https://efergy.us/efergy-tpm> to measure the solar energy
produced. It provides daily energy produced or used on the circuit being
measured for seven days. Then the data roll up into weekly and monthly
totals. This device doesn't communicate via the internet so there is no
data storage on a cloud server. I have been using one on my personal
system for many years. Transmits about 200 feet from the PV array to the
portable monitor that I keep at the house.

Does anyone have a recommendation for a high quality meter that can be
installed near the Main 200 Amp Electric Service Panel at the Point Of
Interconnection in the Main Service Panel for a Grid Tied System
The client wants to be able to track the electricity the household is actually
using
And how much the solar electric system is producing
In the net metering arrangement with Central Hudson in NY, all the client gets
to see on their bill is the net result of the solar credits subtracted from the
actual usage. In this case, the solar generated credits is consistently zero
because the usage exceeds the production
