The exact extract asks for the levels of partner specialist certification and provides three checkbox options: HCSA, HCSP, and HCSE. The correct answer is A, B, C because all three are certification levels in Huawei's partner specialist structure. HCSA represents the associate or foundational sales/solution capability level. HCSP represents a professional-level specialist certification, indicating a deeper understanding of Huawei solutions, partner sales processes, and scenario-based solution positioning. HCSE represents a higher expert-level certification, generally aligned with stronger solution capability and advanced partner competence. Since the question uses checkboxes and asks for the "levels" rather than asking for one highest level or one entry level, all listed levels must be preserved as correct. Excluding any of them would make the certification hierarchy incomplete. The wording in the video contains only these three options, so the extracted answer must include all available certification levels shown.

The exact extract asks which option is not a feature of the residential PV+ESS on-grid scenario. The correct answer is C. Unstable mains or frequent power outages. A residential PV+ESS on-grid scenario is defined by grid connection. The system is connected to the utility grid and normally uses PV generation, energy storage, and grid power together to support household electricity consumption. Therefore, option A is a direct feature: it is a grid-connected residential PV+ESS system. Option B is also correct as a feature because the system is composed of PV and ESS components. Option C describes a different scenario: unstable mains or frequent power outages are usually the reason for backup or off-grid/hybrid operation, where a Backup Box or smart guard is required to switch the inverter between grid-tied and off-grid states. Huawei's Backup Box documentation positions that device for grid-tied/off-grid control, especially when backup power is needed. Therefore, option C is not an on-grid scenario feature.

The exact extract describes a safety-management phase where management makes safety commitments, safety personnel act as a deterrent, rules and procedures are established, and safety supervision plus accident control are emphasized. This clearly matches Supervision and management. In this phase, safety is no longer handled only by instinct or informal personal judgment. Instead, the organization begins to rely on formal rules, management commitments, safety personnel, supervision, and accident-control mechanisms. It is still not the highest maturity level, because employees may not yet be fully self-driven or team-driven in safety behavior. "By instinct" would mean safety behavior depends mainly on individual reactions and basic survival awareness. "Self-management" means employees voluntarily manage safety without heavy supervision. "Team management" means safety is embedded in collective team behavior. The statement specifically emphasizes supervision, rules, deterrence, and accident control, so the correct classification is supervision and management.

The exact extract states that Huawei Smart I-V Diagnosis supports string-level fault locating. This is true. Huawei Smart I-V Curve Diagnosis is designed to perform online I-V curve analysis across PV strings and identify strings with low performance, abnormal output, or malfunction. This function improves O&M efficiency because maintenance teams do not need to manually inspect every string first. Instead, the system scans string-level electrical characteristics, compares I-V curve behavior, and flags abnormal strings for targeted inspection. Huawei's Utility Smart PV Solution page describes Smart I-V Curve Diagnosis as helping find and identify strings with low performance or malfunction, enabling proactive maintenance, higher O&M efficiency, and lower operation cost. Huawei's Utility Smart PV & ESS Solution material also states that Smart I-V Curve Diagnosis carries out online I-V curve analysis on entire strings with advanced diagnosis algorithms. Therefore, the statement is correct: Huawei Smart I-V Diagnosis supports string-level fault locating. Reference: Huawei Utility Smart PV Solution and Utility Smart PV & ESS Solution brochure.

The exact extract asks which micro-grid scenario requires a backup time of more than 6 hours. The correct answer is B. New city micro-grid. A new city micro-grid is a large, high-continuity power-supply scenario, not a small backup-only C&I load scenario. It is closer to the Red Sea/New City type of architecture, where PV and ESS must support broad, continuous power demand and maintain stable power for a large community or city-level load. Huawei's public Smart Micro-grid materials emphasize grid black-start, multiple operating modes, rapid on/off-grid switching, high/low-voltage ride-through, and reliable supply for critical loads. Huawei's Red Sea New City project is described as a large PV+ESS microgrid intended to provide clean power at city scale. Compared with industrial or commercial backup scenarios, this type of new-city microgrid needs longer backup autonomy, so the "more than 6 hours" requirement aligns with option B.
