[RE-wrenches] Adding battery to grid tie

[scot.arey at solarcentex.com]

Wow - what a nice find. EGauge just got too pricey and setting it up reminded me of FORTRAN in college. Thanks for sharing.

Now to find out if my utility might be compatible with the device that uses AMI data.

Correction They still do.  This is what I have customers install when they want to track all usage. Have installed dozens of them with zero issues.

That's actually what I prefer doing on most systems, to have exactly the monitoring I want, at higher precision than the AIO's give, and also independent of the AIO's server, wherever that may be.   And accessible on the LAN, with data storage, if their internet blips out too.  But, not all customers can take the cost of a good egauge setup, which tends to run at least $2k if you start adding DC ct's and voltage transducers to monitor the MPPT inputs.  $1k even for a basic AC monitoring setup.

I suppose one could add an E-gauge system with CTs in appropriate locations.

I like data. Not being able to measure AC coupled PV input is far from my ideal in my opinion, but when there is no other practical choice, I guess I would do it. In fact, I have done ita couple of times.
