Gentleman and Ladies. Be kind to each other. Attack the idea , do not attack the.person.
Like I mentioned. I thought of this as well.
1. Is your battery going to be on and off the premise during the day while solar power is charging? Say you have multiple cars and or motorbikes and you have the ability to manage your cars on site time. Which honestly does not work logistically.
2. If you have multiple cars that can be charged and than used, charge and used... Like a fleet. Probably can work.
3. Go watch Matt Ferrell's undecided on his take of Solar power. Got a few video discussing how the Solar grid tied system works. And it applies to battery solar grid tied system too.
4. Once you able to wrap the requirement of TNB grid orffering 60HZ, 230V. Than you can think of a inverter that is smart enough to be grid tied and also hybrid battery.
Btw: NEM requires that if TNB is down, that all back flow of electricity from Solar Nem to also shut down completely, as a safety feature to not electrocute OUR TNB technician doing repairs.
I do not work for tnb... But they are our Technician. Pls be kind to TNB technician.
Since your home already have solar panel installed , why not just upgrade the system to store any excess energy generated for the day?
Calculate the maximum energy your solar panel able to generate and buy enough battery according to maximum generated energy
This is more safe , easy and cost effective to maintain then buying EV car as an energy storage
