Thanks to Emporia’s excellent tools, I have outlets and usb chargers in my house that only work when I’m generating excess solar. I don’t need my power banks every day so they get plugged into those outlets.
Oh, and my car. My car only charges as fast as my solar generation permits. I love Emporia.
I’ve got a 5kW array of panels so yea, piddly stuff like charging USB is nothing - it’s more the principal of the thing.
My EV charger is definitely the biggie. The system will dynamically adjust charging current in 1A steps to make use of available excess generation. It works pretty well - 16kWh spinning my meter backwards would earn me a whole $1.50 - instead it added ~20% charge to the car.
I’d love to have smartedr charging of the car. Currently we just use a plug in portable charger, which actively advises against putting anything between it and the socket (e.g. no smart plugs).
One day we will get a nicer car and then install an appropriate charger that can connect to home assistant 😍
