[oil pan 4]

There is nothing wrong with grid tied.
I just think its absurd to do all that off grid stuff when there are power lines and service drops all around.

I didn't hear the part about it having lithium batteries and figured it had lead acid since its "counter weighted" and looks like it needs tens of thousands of pounds of counter weighting.
Having lithium is even worse, its light, more expensive, LiFePO4 sucks in the cold (if that's what they are using) and its not currently recyclable.

Smartest thing to do is put lead acid in very slow moving (fork lift, golf cart) or stationary monolithic formations (like this) and put Lithium chemistry in the smaller things that stop, go and move around a lot.

I like the part about how they say "it wont be affected by grid outage". That is hilarious. Every single person with an EV will be thinking the exact same thing when the power goes out. And that is to get down to the solar charger. Then a huge line will develop.
So power outage means the solar charger will be over loaded and sucked dry as the sun goes down.
Something like the gas lines of the 1970s oil embargo and energy crisis.
