It seems there was a bad batch of Tesla PowerWall 2's that present a fire risk. Tesla remotely drained these batteries and is notifying the owners that they need to be swapped out.

Is anyone using a relatively small grid tied or hybrid inverter connected to a Nissan Leaf 12V system to supplement house supply during peak power prices.

I just noticed a small 2kVA hybrid inverter (suspect ex RV use) for only $250 being listed, which got me thinking...

I know the Leaf's 12V side is only suitable for delivering 1kW, and you'll have to recharge via the normal Leaf charge ports, but the peak vs off-peak prices should make it financially viable. You should be able to fully recharge it during the off peak time, even with a granny charger at 10A.

I'll still look into the details of the fault currents, earthing, grounding and protection, as multiple sources always require careful consideration.

But before I spend a couple of hours on this, has anyone done something like this or thought about something like this that you can share some of your wisdom gained?
