@artyr3 I hear that they are working on the power requirements on their end as well. Honestly, having it on part of the day might be a way to reign in some of the negative effects of always being connected. You always use something better if you have to be intentional about it too. That is part of my reasoning for going off-grid in the first place. What do you think of Tesla Powerwalls? They are expensive, but have a good warranty. You can't say making your own system up to code is cheap.
