Hello TMC Energy folks, I have an opportunity to buy a Powerwall 2 from an estate sale in SoCal. I'm trying to gather as much info as I possibly can before deciding what to do. The cost of the Powerwall will only be ~$1,000, but I'm gonna have to find an installer to do some work...this is my thought so far: 1) Find installer to uninstall PW2 and gateway from solar system at estate home and set up to function without it. 2) Have installer install PW2 and gateway at my residence (I have a 7.4kWh solar system installed). 3) Have it connected to my Tesla account so I can monitor it/change functionality/etc. I know it is going to cost a decent amount in labor for this to be done, I'm thinking at least a couple thousand dollars or more probably? I'm just not sure if it'll be worth it in the end for me. My bill through SCE at year's end is already negative, even with my Model 3. I'm on a grandfathered TOU-D-A plan and charge after 10pm during super off peak. I don't think there's any real ROI on the PW2 to be had for me until I get a 2nd electric car. I think it'll only function as a battery back up for me? I believe I can arbitrage and have the PW2 charge up during off peak/shoulder hours up to 2:00pm on my TOU plan, and then I can feed that into my house during Peak hours? This'll save me some Peak power usage, but since SCE basically only pays $0.03 per kWH at the end of the year, it isn't going to be a lot of money, correct? Just kinda looking for some input as to whether I should go through with it or not...thanks for taking the time to read.
