Good point. You can add battery to existing NEM 2.0
Not sure if there are wattage limits, previously I thought I saw battery inverter up to 2x PV inverter? So the EG4 "12kbat" could be acceptable for minimum 6kW GT PV.
You may be allowed the choice between charging from PV only and later discharging into grid, or charging from grid and later discharging only for loads.
Under NEM 2.0, Peak used to be 2x Off Peak, I think, so some value to time-shifting exports. (NEM 3.0, dramatic value). But if $0.15 added to all times, same dollar but smaller percentage difference.
Do we know yet if OP wants to charge night time or day time?
Using battery to shift time when power is drawn from the grid would only be beneficial if he insists on charging during peak time of use (4:00 PM to 9:00 PM?) Easy to avoid.
What good can a battery possibly do for him? (Unless it is to make an offgrid system, so he can add PV without losing NEM 2.0 status of existing system.)
