I guess I'm overly optimistic in hoping that electrical engineers could
understand these concepts. Next time I'm sending in a modified
drawing without the genset.<br><br>

<font face="arial" size=3>As for 2, from our experience with the local
IOU, be careful when mentioning a motor-driven generator. They don't
understand that the XW can't sell that power--directly-- to the grid.
Since the cat is out of the bag, I think you'll need to show that the gen
set only charges the battery and passes thru the XW to the dedicated
loads.<br>

<font face="arial" size=3>May be simpler not to mention generator?<br>

<dd>Interesting that this topic comes up at this time:<br><br>
<dd>1. We inherited a grid-tie project wherein an elderly client was sold an SW installation some years ago. Come to find out, the installer never filed anything with the utility. The client was caught recently back-feeding without permission by a meter reader and told to cease and desist. We filed an application with the utility thinking this was a long shot since the client's SW inverter did not have the requisite Grid-tie Interface (GTI). We have several GTIs sitting on the shelf, but the inverter does not have the proper interface so one could not be installed. Lo and behold, the utility approved this installation for interconnection.<br><br>
<dd>2. We have an application to the local utility (PG&E) pending for a three XW installation with a motor-generator. We have received multiple communications from PG&E doubting the acceptability of the XW system for use as a gird-tied battery-back up system. We are hoping that PG&E accepts the listings from the various agencies and approves the project.<br>
<br>
<dd>Interesting that the old, non-complaint system receives swift approval but the latest and greatest gear hits a regulatory road block! We'll keep you posted.<br><br>
