Hi I am new to this topic. I've read a lot of posts in this thread, very useful.
Currently I've got solar panels at home, and looking at adding batteries. Main reason is to have power during an outage.
However, a PW2 costs roughly $18k. For that amount I can buy a 2nd hand Nissan Leaf.
I've searched a lot, but what are currently the options to use an EV as house battery? Is that possible, is that supported, any warranty issues?
So my plan would be to commute with the EV, and when I come home and the power is down, use the EV as backup, being charged by the solar panels.
You can use a Nissan Leaf to power an inverter to run essential appliances in your house in an emergency. Just google it. I have tried (for fun) and it worked. With the ignition on it charges it's 12v battery from the traction batteries at a rate of 1kW, which is fairly respectable and plenty to run lights and fridges (but not stoves or microwaves).
Thanks @tripper1000 . I won't be able to charge the EV from my solar panels during an outage, right? As the system shuts down during an outage to not kill the people working on the grid. Is there any workaround that?
As my goal is to still have power during an outage for extended periods of time.
You need to have a relay that can disconnect your house from the grid in the event of a grid outage. I think you need to talk to your lines company as it needs to be one they approve. I am not sure all of the lines companies allow them at this stage as if something goes wrong with one it can kill one of their workers.
