I reserved a Powerwall 2 over two and a half years ago. The price of the Powerwall was $5500 and the Gateway was $700. Installation just recently became available in South Carolina so I contacted a certified installer. I was surprised to find out that the price of the Powerwall 2 had increased to $6700 and the Gateway to $1100. Since I want to install 2 powerwalls, this increases the price by $2800. I expected Tesla to honor the price at the time of the reservation. However, when I called I was told this was not the case. Has anyone else had this situation? It seems this is similar to getting a rain check on an item that is not available. When the item becomes available you do not pay a different price.
