PV on the line side of the FHP
The installation of an aPbox is to monitor the generation of the PV system and provide
data to the FHP system.
In this scenario, one aGate X only supports one aPbox connection.
NOTE
When there is a grid outage, the separated PV system will disconnect from the
grid and shut down.
The example site layout is shown in the following figure.
