I am looking into getting an emonPi setup going to monitor my consumption on my panel, but I also have a PV array.
I have a SolarEdge inverter (SE6000) that I have a hardwire ethernet connection to, with Modbus-TCP enabled. I know that the API can be used but with infrequent calls. Can I use the Modbus-TCP connection to bring in the PV data, or would it be recommended that I just install separate CTs on the PV feed into the panel?
(ps. sorry i this is the wrong topic to post this question to!)
I’m looking to monitor SolarEdge production. I have one free channel on a WattNode Modbus meter. Is a single CT enough to get a reliable reading from the system? It doesn’t have to be perfect, but I’d like somewhat reasonable accuracy, +/- 10% maybe?
