I was looking at the whole house monitors like the TED and my own UK made monitor.
Elite Wireless Electricity Monitor
When it occurred to me
, the current probe could be placed on the
output of your grid-tied inverter(s)!
It would monitor your PV production, and like a Kill-a-Watt, display the data in kWhs and in $..
My Efergy saves kWhs daily for a week, then compresses it to a monthly
total number at the end of each month. Up to 24 months.
So, if I ever get to buy some EnPhase inverters (or Chinese copies), I can get
some more use out of my Efergy unit.. It can handle 120 or 230vac easily.
It does not have a USB I/O like the TED, but the cost is less, about $70 IIRC.
Cheers,
Rich
