My microinverters communicate with a device known as a Solar Gateway. The sole purpose of the Solar Gateway is to communicate with each of the microinverters (over low power Blu-tooth) and collect that stats which are stored on the gateway, and then connect to my LAN via Ethernet. My switch powers the Solar Gateways via PoE.
So at night the microinverters are completely dead and the Solar Gateways report no connection to them. However, I can still talk to the gateways and pull historical data. The data is compressed on the gateway and it can store about 50 years worth of stats (doesn’t take much room). I can also pull the data from the gateways using its REST API and keep it all in a local database on one of my servers and create pretty graphs. Would be nice if Sense would expose a REST API so that I could suck data in from it as well.
I can ssh into each of my gateways and run “suntop” to see how each microinverter is doing real-time like so:
I have some cloud cover this morning and there is some shade the larger roof mounted array, but the ground mount is in the clear so I’m getting better numbers from it at the moment.
Yes, I have 2 failed microinverters at the moment. The replacements are actually being delivered today (along with a couple of spares).
