Since we all want to promote green technology in our daily lives, we should conserve our energy usage and find solutions that go in this direction and also help reduce our consumption costs.

I imagine that we can install batteries to store energy captured by the solar panels for our homes, so that we don't have to totally rely on the main grid. This should help reduce our electricity bill, right? But, after going through some posts, it sounds like it is an illegal method?

Which post says battery with solar is illegal? In fact many DIY go for this option because the profit by vendors from NEM can be used to buy a battery size of 48V 100Ah.

If you understand Solar panel inverter that is not the problem , there is no need to separate it.

The problem is:-

1.) Night usage of electricity exceed 1500kWhr. Your idea does not solve that.

2.) The inverter used is most likely a single phase version , which means it is not able offset all 3 phase daytime electricity.

How about this option: a three-phase grid-tied hybrid residential-storage inverter with battery support, and an extendable/stackable system allows us to add more solar panels in the future. It can support EV charging and power backup during the main grid blackout.
