I think that technically, the combiner panel is not compliant if the
possible feeds from various sources exceed 120% of the busbar
rating. <br><br>
Inspectors have been reasonable on this issue, as it can be done
safely. The solution, if the AHJ won't accept a small combiner
panel is to use a panel with a higher busbar rating and a main breaker
small enough so that the combination of the main and solar feeds does not
exceed 120% of the busbar rating. It can result in some awkwardly
large and technically unnecessary boxes. <br><br>

<blockquote type=cite class=cite cite="">If the combining panel is next
to the main panel, can you use a Main Lug panel as the combining panel or
does it need a main breaker? I'm not sure what the purpose of the main
breaker would be if there are no loads.<br><br>
