What options exist to provide the equivalent of a Tesla PowerWall from the
removed pack of this Rav4EV?
Rather than fill up this vehicle oriented forum, perhaps a viewer can redirect
me to a suitable forum? Also, I feel it's important to note that we have a
PowerWall and 9Kw of solar PV and it would be great to make this all work
together. I have real estate on the south wall adjacent to the PowerWall, no
windows, power meter and primary cut-off all in the same location
The below from me, not Fred. I plead editor impairment.
I've had good luck augmenting my PW with ~250w micro inverters powered
from 36 v batteries. Those 36v batteries coming from battery banks
made up of ebike/hoverboard batteries and golf carts. All LFP or the
ebike chemistry. I had a single battery PW which I eventually
upgraded to three batteries and thus no longer attempt augmentation.
I've fiddled trying to do similar with 12v out of both imievs and
Teslas but was unable to get good ~36v out of 12v with cheap DC-DCs.
I do recomnend 36v into microinverters.
I have a couple of leftovers that I no longer have use for:
1) I bought three PW batteries to add to my single battery system but
apparently killed one. Likely by crossing L1 and L2. I wish to find a
home for the non functioning PW battery. Or find a repair path.
2) Long ago, I bought an EVTV off grid unit, 6kw/15kwh battery/inverter
I think, intending to make another of my electric meters/transformers
more immune to grid outages. I've lost interest in that project so
would like to find it a home.
I agree with Phil that PW upgrade is almost certainly the easiest and
cheapest path.
