The Solar installation is great. It produces enough power to run the house and chage the battery for the cloudy bits of the day. However. I've had a lot of trouble with the smarts on the battery controller. From day one it was very inconsistent. Sometimes the battery drains back into the grid during off-peak hours. Other times it, does not power the house at all, even though it's at full charge. It took nearly 3 months of back and forth with Tesla to fix this problem. Harrisons was not a great help during this phase, but it was not an installer issue. it was a product issue. After Tesla finally fixed the firmware, it now works as expected. In hindsight, I should not have gone for the Tesla battery. But the rest is great.
