I agree. I think it is the ITC issue/simplicity/various regulations and that is why h2o is going to have a hard time grid charging the SGIP powerwalls. Heck I do not have solar and I am having to force the application to charge the batteries off peak. If the App was left to do what it wants to do my batteries would have been sitting at 15% capacity for the last 3 weeks in standby.I do not think this is accurate that Tesla would need to reprogram the app. Individuals in other countries, and a very limited (possibly as low as one who reported their experience on this site) number of individuals in the US do have grid charging with solar. The point being it is a configuration setting that disables this functionality rather than missing functionality. Why Tesla chooses not to make this option available in the US has been discussed at length, but the general belief has been some combination of the ITC and the patchwork of state/local/utility regulations, some of which might prohibit or have other rules around grid charging combined with solar/NEM. It also seems consistent with Tesla to keep things simple - fewer options - so it has been easier for them to just set a blanket rule for the US.
Some Tesla customers desperately need them to make advanced setting available in the application. My tesla app needs to grid charge my batteries off peak. Others need/want to be able to customized when and how they use their solar/powerwalls due to differences in rate structure and having a better idea of future weather forecasts and solar output changes in the near future where they live.
