Power One Inverters will easily string that low. We have used quite a few
of these with no problem. They are ungrounded on the DC side.

JESSE:
The Power-One specs lists 160V to 530V as the MPPT working range. It's
possible to set the per MPPT input as low as 120VDC. Power-One does not
provide info for loss of efficiency if the high-temp DC in[put voltage
drops below 160V.
Do you have any info on performance degradation
Friends:
We have a client that wants to divest of 8 Fronius LG-4500 LV
inverters. They are experiencing a high number of failures. The Fronius
have an unusually low DC input window: 150 to 450 VDC. This means the
stringing will result in a lower voltages than typically found and makes it
Off the top of my head...Power-One?

I think some Solectria inverters have a low number (115vdc). The Solectrias I
have worked with had a max DC voltage of 400vdc though.
