6.2 BOSS System
Alencon’s Bi-Directional DC-DC Optimizer for Storage Systems (BOSS) controls the charge
and discharge of individual battery racks with a galvanically isolated approach. BOSSs are
generally co-located and easily daisy chained to a PODD. An example BOSS system
architecture using a Single PODD configuration is shown in Figure 10.

6.3 GARD System
Alencon’s Ground Arc and Rapid Disconnect (GARD) System is a protection device to detect
harmful arc and ground faults in PV arrays. These can be configured as stand-alone
protection or be paired with other Alencon devices (ie. SPOT or BOSS).
