Howie:

The IG has an integrated disconnect section, but it the electronics are not removable from the disconnect. Therefore it is not safe to replace an IG unless it is dark or you can tarp the modules.

The Plus series has two chassis that mate. You can turn of the DC and remove the electronics for repair, which we have had to do all too often.

We had an IG burst into flames and scared the heck out of the widow who was home alone. She called the fire department and then called us. Sure we get replacement inverters for the asking, but we get tired of asking.

Thanks for the feedback Kistopher.  1 question:  I thought that the IG
also came with the integrated AC/DC disco as well as the IG Plus.  I know
the IG doesn't come with the string fusing.  Am I missing something here?

Thanks,
Howie
