The exact extract asks which feature can increase the energy yield of a PV system. The correct answer is C. Module-level optimization. Module-level optimization improves generation by reducing mismatch losses between PV modules. In a string system, shading, dirt, aging, module orientation differences, or manufacturing variation can cause one weak module to reduce the output of the entire string. Huawei optimizer technology allows modules to work more independently and helps each module operate closer to its maximum power point. That directly increases energy yield. AFCI is a safety function for arc-fault detection and shutdown; it protects against fire risk but does not primarily raise generation. Smart string-level disconnection is also a safety and fault-isolation feature. Module-level shutdown improves emergency safety, not energy output. Therefore, only module-level optimization directly matches the energy-yield improvement requirement. Reference: Huawei HCSA-Sales-Smart PV V2.0 C & I Solution and optimizer training extract.

The exact extract says: “Huawei residential PV+ESS off-grid solution includes the whole-house backup box.” The correct answer is A. True. In a residential PV+ESS off-grid or backup scenario, the system must safely separate from the grid and supply household loads during power outages. A whole-house backup box, or backup switching device, is used to manage the grid-tied/off-grid transition and provide controlled backup power to the home. This is different from a simple on-grid PV+ESS scenario, where the system may operate with the grid and may not require a backup box unless backup operation is needed. For off-grid or backup use, however, the backup box becomes part of the solution architecture because it supports safe islanding, load connection, and reliable power continuity. The statement is therefore correct in the residential PV+ESS off-grid context. Reference: Huawei HCSA-Sales-Smart PV V2.0 Residential Solution training extract.
