So it is 200 kW, allowing two cars to charge at pretty much full speed, but how many kWhs? It looks like 6 Powerpacks, so that would be 1,260 kWhs. Or enough to charge ~18 100s from 10% to 80%. (Assuming of course it is setup to work during power outages and not just be for peak demand shaving.)
How much do you think would be appropriate to install? (Both kW and kWh)
