My system was installed by a 3rd party (A&R Solar in Seattle) with 2 Powerwalls, LG panels, and Enphase micro-inverters. When off grid, the solar panels provide power to the house, and excess goes to charge the Powerwalls. Note that if house demand is high, there may not be enough solar to charge a car at full rate. In this case, the car will draw from the Powerwall until it reaches the charge level you set in the app (I set mine to 95% so the car charger cannot deplete the Powerwalls too far).Thanks for the info. I suspect the rep I'm dealing with is not knowledgeable about Powerwalls and/or has an ulterior motive.
Do you know if the Powerwall can be charged by non Tesla solar power systems while the grid is out? Our solar power electronics is provided by Enlighten, not Tesla.
