"Full backup functionality will also be available with a backup unit from 3rd party vendors." in addition to its "2000 W of convenience power". It's still grid-tied as it comes out of the box.jray3 wrote:Yes Joe, the Sunny Island was based on 48V, but the new model will support packs anywhere between actual voltages of 100 and 600 VDC. Our 360V pack is right in the middle.
Here's the spec sheet.

I'm afraid that I've lost sight of what it was we were trying to do.
In the few power outages we've had over the last couple of years all I did was hook up my 48vdc-->120vac inverter and ran an extension cord over to the refrigerator, and I was ready to run my 12vdc-->48vdc dc-dc converter from the i-MiEV's 12v battery to slowly recharge that 48vdc pack. Luckily, the outages were less than about ten hours.
The longest my power was out for was after the Loma Prieta earthquake of '89, and that was over a week. I figure if it happens again I'll be able to cobble up something to charge the i-MiEV - providing my garage is still standing. My ground-mounted solar array is well under 360vdc so I can't use it directly to charge the i-MiEV through the CHAdeMO port. At worst I can clamp that array's output directly onto the 48v pack and then use that to charge the i-MiEV using the 48vdc-->240vdc 4kW inverter through the throttled-down EVSEUpgraded Mitsu EVSE.
