aPbox Manual

Application
While the aGate has a PV breaker as an optional component, there are some situations in
which the PV system cannot be connected through the breaker or where there are
multiple PV connections needed. In those instances, an aPbox can be used to connect the
solar source to the aGate or the grid.
There are two scenarios that define how the external connections with an aPbox are
connected.
PV on the load side of the FHP
Installation of a RC65 is required to meter the production of and cutoff the connection to
an individual PV system installed on the load side of the FHP system due to:
• Existing constraints, such as the location of the PV system and the aGate X, preventing
the PV system connection to the aGate internal PV interface.
• Multiple PV systems on-site prevent a distinct PV system from being connected to the
aGate.
• The total PV system output power exceeding the power rating of the aGate internal
PV interface.
• The total amount of the PV production exceeding the aPower energy capacity.
One FHP system supports up to two RC65 connections. The FHP system controls the PV
system connection according to the loads consumption and SOC of the aPower, and
captures the PV production.
The example site layout is shown in the following figure.
