I have a sunny boy inverter with sunpower monitor for production and consumption. The data is very delayed, at least 10-15 minutes. I use https://www.amazon.com/Efergy-EE-HH-T2-Engage-hub-kit/dp/B0128Z0K1I/ref=mp_s_a_1_1?ie=UTF8&qid=1549312767&sr=8-1&pi=AC_SX236_SY340_QL65&keywords=efergy+engage&dpPl=1&dpID=410UBhyRefL&ref=plSrch and (Updated) Efergy 2.0 (Connect) for real time production data to trigger additional loads.
You may also want to take a look at curb or aetoec CTs.
