Backstory to this is located here: Tesla PW price increase I currently have a 13kW (Peak) solar system that's grid tried using Enphase micro inverters, after doing a ton of research on energy storage for existing grid tied systems I ended up going with the same process Tesla uses with the PW. AC Coupling, it's not as efficient as DC coupling but I'm not about to re-wire all the modules on the roof. That being said, the inverter i'll be using for this is: 12000 Watt Inverter | Pure Sine Wave 48V 12KW Inverter Charger For the storage I bought a 60kW battery pack which I'm in the process of taking apart (pics to come). In the meantime I came up with a quick mock up of the wiring for the system. I'm currently building a BOM of all the other parts I'll need, as more parts come in I'll update this thread.
