As a new Powerwall owner I find the documentation totally inadequate. It seems to be written in a way that gives plenty of sales hype, but little detail. Like what is the real difference ( implications at a practical level) between the Advanced mode options of Balanced and Cost Saving. Like how do you control the system when day today weather variation makes a difference between 3 kWh and 13 kWh solar generation. Like how do you configure when on holiday and you only use 3 or 4 kWh per day (do I increase backup to say 75%?, why no holiday mode?). Like what does the yellow and green circles after the Storm Watch option tell me? They don’t seem to add anything obvious. Like how am I supposed to get a greater off peak charge when we are likely to use more electricity tomorrow or when we know the solar charge will be down because it is forecast to rain all day (or the converse). The only option seems to be to wake up in the dead of night, increase back up percentage to a very high level and turn it down again just before it goes onto peak time.. Like what happens when the clocks change? Powerwall time can only be seen on the graphical screen or by downloading data. How am I supposed to sync up when I don’t know if Powerwall respects local time zones and changes to/from daylight savings at the right times? I know my electricity smart meter is permanently on GMT (UTC) so do I have to change Powerwall off peak twice per year?
I can monitor what Powerwall is doing but cannot control it. Does Tesla intend to base Its design on a mantra of the customer never knows best and therefore can contribute nothing? That’s the way the documentation/app design appears to me as someone who feels he has paid out for better. Answers when I rang Tesla customer were inadequate to. They seem to have read the same manuals and knew little more, even though they claimed to have contacted their technical guys. Honestly, my confidence levels in Tesla have plummeted.
