The Enphases are near > bullet proof. You'll definitely need to check the car-> DC2DC converter -> Microinveter combination to make sure it works with your powerwall and ATS when the grid is down. My advice would be to have a separate DC2DC converter for each microinveter, rated above the microinverter's peak power. Hopefully when the microinverter is working at max power the MPPT algorihtm won't take offense at being fed from a power supply instead of a solar panel. Perhaps something like this 12->24v 480 watt inverter: https://amzn.to/2HgKlc8 (it's not isolated...but as your micro inverters will all be in parallel, that should hopefully not mater??? I'm not sure if microinverters take advantage of the fact that individual solar panels are isolated or not....) Jay -------------- next part -------------- A non-text attachment was scrubbed...
