Ante-litteram I've made the very same system for myself: a small p.v. with 8kWh LiFeP BYD storage to have: - AC coupled solar inverter functioning in case of an outage - battery backup for critical loads (fridge, freezer, VMC, lights, computers) in the same case when there is no Sun shining - a small generator to recharge in case of emergency I feel the pain of a totally non-integrated IoT where devices can be barely commanded via ModBUS and only some can be monitored via ModBUS or MQTT, crappy flexibility and overall design etc... No vehicle-to-home integration so far (while a monodirectional to recharge an EV from p.v. depending on current availability is on sale from my battery inverter vendor) and an uncertain possible future expansion due to the crappy design EVEN if I choose "the most flexible and open solution on the market" (that's not their advertisement, that's what I've read in various forum) a Duch-centered brand with a light blue colored theme... I still wait for: - a damn open and common protocol to pilot IoT devices - a damn realist design, witch means knowing how "a complete home" can be instead of try selling self-contained walled gardens crap I doubt without public research that happen soon...
