Page 11: Product Overview
Installation and Operations Manual Product Overview The aPbox can be used to measure the amount of electricity generated by a PV system, and can also be used as a disconnect to sever the connection to the PV system when the photovoltaic over-generation is triggered. It supports access of up to two PV systems with a total current of no more than 65A. -
Page 12: Components
(Communications) • Control System: Consisting of a DC Power, a relay and a contactor, executing the command from the aGate X that allows the aPbox to disconnect from or reconnect to the PV system. • Metering System: Metering the PV production by a built-in meter and CTs. The CTs collect current data from the PV system and forward that data to the meter for analysis and reporting to the aGate X. -
Page 13: Application
While the aGate X 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 X or the grid. -
