If this configuration would actually Start up, it seems like the 12VDC-to-120VAC inverter
would be using very little from the battery, since the grid-tie inverter
would try to make it's voltage just a tad higher..

Anyways, I was thinking this might be the lowest cost way to DIY off-grid power..

If it did work, you could stack the little 300 watt grid-tie (or Enphase) GTIs
and get some nice power-point-tracking from each panel..

Comments please:

Thanks,
Rich
