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.
You don't say what, if any, battery backup you have.
If it fits your budget, I can HIGHLY recommend a PowerWall. Though I'm
not sure how well it might work without a good sine wave inverter. It
does work well with all grid tie inverters. Though a grid is not required.
I can tell you that, once your PW battery is fully charged, balancing
load and supply is a very delicate matter.
I'll extol PW virtues if asked.
