CHARGING OUR EV OFF PV PANELS
Can you offer any help with two questions related to charging our
Tesla Model 3 off our Tracking 3K PV system?
1. Since our PV system inverter does not produce a sine wave it has
been suggested that I might go through a filter to make the car
accept it. Do you have any idea this might work?
2. This summer we are making plans to add a 4K stationary PV set
using an OutBack sine wave inverter to our house. The present system
works well so are wondering about using a transfer switch between the
two independent PV sets. As we now must manually manage the power for
our house anyway, that should be helpful by giving us more degrees of
freedom as our usage varies.
Thanks

it boils down to how many range-miles you have left, how many
range-miles you need to put back-in to get to the next EVSE, and how much
time you have to charge?
Overnight sleep or @work, plan to charge for at least 7 hours. L1 might
regain you (3.5mph*7= ) ~25 miles of range.
It's not quite that bad. Our Nissan Leaf gets about 4 miles per KWH.
L1 charges at about 1.44 KW. That's about 5.6 miles range per hour,
or 40 miles for 7 hours of charging.
Charging efficiency will reduce this a bit. But then, most full-time
jobs will have your EV charging for 8 or more hours a day.
*Only buy an EV with a L2-6kW (j1772) charging capability that also has a
L3(quick) charging port.
Maybe if you live in California. Where I live, there aren't any L3
EVSE's within range of my EVs.
My home EVSE preference:: have a L2-6kW (j1172) or a L2-10kW (Tesla) hpwc (=
no surprises you can always get a good/solid charge).
I do 99% of my charging on L1, in my own garage. That's been fine for me!
