My phone app and the system stopped communicating. It was just that the outlet needed to be reset, but David was extremely helpful and concise about all of the instructions to make sure that the system started talking to the network again. He also gave me instructions and a link for checking with Edison about what my production is. Very helpful!

When Oscar says they are having a flash sale, please don’t delay. I mean it. Take advantage while you can because that’s the best pricing you can find anywhere. Add on top that, professional customer service throughout the whole process, you’re good to go. I had work done by the company before, that’s why I went back. Have a good day.
