Installation
Any circuit connected to the SE Box will not be powered when disconnected from the grid. During
on-grid operation, these circuits are still metered by the internal site net metering with no additional
metering hardware required.
However, if non-backup load panels exist upstream of the SE Box, additional CTs are required. In this
case, refer to "Usage of External CTs".
