[RE-wrenches] Metering

[Kent]

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.
