[RE-wrenches] Tesla 2.0

[Dan Fink]

I agree on checking into Sonnen, as they are using  regular Outback Radians
and the high<>low voltage conversion electronics are built into the unit.
The main complaints I have heard so far is that it's a really crowded
compartment in which you have to do your wiring.

You might also look into the Iron Edison Lithium-Iron packs; lots of
success stories, and they can scale up far bigger than Tesla....took a
couple of my classes on field trips there last week. 225kWh battery backup
for a mansion in California, big cell repeater towers in Canada, big
houseboat on Lake Powell.....the technology is safer than the Li-ion in
Tesla/Sonnen, it vents steam instead of flames and toxic chemicals if
everything goes south. Accessible and easy to wire, including the BMS
computers.

China is banking on Li-Fe instead of Li-ion with their massive push to
solar, wind and utility-scale storage.
