Dear Community
This Tesla Solar project will make me an electrician soon, I read all the posts but still couldn't figure out some items, also I am trying to optimize my investment. Any suggestion or help will be appreciated. I am in N. California , PG&E
Situation:
-We have a 125a main panel, with 40 amp going to HVAC compressor and 90 amp going to sub panel in the second-floor bedroom, which is full (Electric Range, Electric Dryer, Gas Heater, Tankless Water Heater, and regular stuff for a 1900 sqft home). Currently consuming 400kwh monthly on average
-I want to install EV charger after solar is completed since all the electricians recommend a subpanel near the main service panel or load balancer I decided to wait until the solar project is completed. So I want my solar to EV charger ready with minimum cost
We are installing 6.8kwh Solar panels and 1 Powerwall. (we started with 4.4kwh and 1 powerwall+ and at that time it was all house backup)
This is the latest design document from Tesla, but I am confused.
1-This will be partial home back up, I can accept separating the 40a HVAC compressor out but is this means something my home will be also included?
2-Not to have all house back up: will this effect
-Nem 3.0 requirements? if any
-Can I still to time of cost use? What I mean, can I use the electricity I produce from solar in the day time, when peak hours 4pm-9pm, use it from the battery and then use grid? Will that mean only part of my home will use the powerwall and the rest will still use the grid even on pick hours?
-Should I increase it to 2 powerwall to optimize the cost?
3-If they will decide which items on my current subpanel hooked up to the powerwall, how this will work, currently only one cable going to subpanel and subpanel divide its to different circuit, how they will will split it to powerwall vs non powerwall
4-In previous design document there was something called 125A distribution panel but this design do not have it. what does it mean?
4- Future EV Charger, where this EV charger will be connected? Before electricians said, once Tesla put a subpanel outside, they can hook up the EV charge to it so it can be less costly. does it still make sense?
Thank you
