Free Practice Questions for Huawei H19-260_V2.0 Exam

The exact extract asks how the traditional solution ensures PV DC-side security. The correct answer is A, B, C. A fuse is a traditional protection component used to interrupt excessive current on the DC side. A DC combiner box is also a traditional PV-side component that combines strings and normally contains fuses, surge protection, and DC isolation/protection elements. A manual disconnect switch is another traditional method for isolating PV strings or DC circuits during maintenance or fault handling. These three options are directly associated with DC-side protection and isolation. Option D, AC switch, is not correct because it belongs to the AC side of the inverter output, not the PV DC side. The question is specifically about the security of the PV DC side, so AC-side switching cannot be counted as a DC-side protection method. Huawei’s newer C & I safety materials contrast these conventional protections with intelligent DC-side disconnection and rapid active protection.

The exact extract asks which Huawei technology proactively shuts down the DC system to prevent a PV DC-side fault from spreading. The correct answer is D. Smart string disconnection. Fire suppression is a reactive measure after a fire starts, not the proactive DC-side electrical isolation mechanism. Smart terminal temperature monitoring may help identify abnormal heat, but it is not the technology that shuts down faulty PV strings. MPPT insulation monitoring can detect insulation abnormalities, but the named Huawei active shutdown technology is Smart String-Level Disconnection, or SSLD. Huawei describes SSLD as identifying DC-side faults such as reverse polarity, backflow current, and short circuits, then implementing automatic string-level shutdown on a millisecond basis. This prevents fault expansion and improves active safety at PV plants. Therefore, the extract points directly to smart string disconnection. References: Huawei SSLD and utility Smart PV safety documents.

The exact extract asks which listed items are Smart PV partner incentive types. All five listed options are incentive-related mechanisms, so the correct answer is A, B, C, D, E. A basic rebate is a standard channel incentive linked to partner sales or commercial contribution. A capability rebate rewards partners for building required capabilities such as certification, technical competence, delivery readiness, or business maturity. MBO, or Management by Objectives, is normally used for target-based incentive assessment where a partner receives benefits after meeting defined business objectives. JMF and MDF are marketing-related support funds; they are used to help partners carry out market development, promotion, customer events, campaigns, and joint business growth activities. The question uses checkboxes and asks for “partner incentive types,” not for one best incentive. Since each listed term is a recognized incentive or support mechanism in partner-channel policy language, none of the options should be excluded.

The exact extract says: “Traditional inverters use the manual string shutdown solution to disconnect equipment internal fault or PV modules fault.” The correct answer is True. The point of this question is the contrast between a traditional DC-side protection method and Huawei’s smarter active-disconnection approach. In a traditional PV inverter architecture, when a string fault, module-side issue, or equipment-side fault occurs, isolation often depends on manual disconnection through DC switches, string-level fuse/combiner design, or onsite service action. That process is slower and less granular than intelligent string-level or module-level shutdown. Huawei’s newer C & I safety positioning emphasizes active DC-side fault protection, intelligent string disconnection, and faster shutdown to reduce fire and equipment-damage risks. So the statement is correct when describing the traditional approach: it depends on manual string shutdown rather than automatic intelligent isolation. Huawei’s solution is designed to improve this by enabling faster, more precise DC-side fault response. References: Huawei C & I Smart PV safety material; Huawei AFCI and active-safety materials.

The exact extract asks what Huawei rack-level/pack-level optimization design mainly solves. The correct answer is A. Reduce the impact of battery inconsistencies on the system. In large ESS deployments, battery packs and racks do not behave identically over time. Their SOC, SOH, temperature, internal resistance, and aging rates differ, and these inconsistencies reduce usable capacity and may force the whole system to follow the weakest pack or rack. Huawei’s Smart String ESS design uses pack-level optimization, rack-level management, and refined electronic control to reduce the negative effect of these inconsistencies. The purpose is not primarily to slow every cell’s chemical degradation, increase physical energy density, or expand the nominal rack capacity. Those may be indirect commercial benefits, but the technical design principle is mismatch mitigation and refined energy management. Huawei describes pack-level optimization, rack-level management, and safety design as controlling lithium-battery inconsistency and uncertainty, improving available capacity and safety.

The exact extract asks which areas are included in the Data Center Facility Pre-sales Specialist Certification. The correct answer is A, B, C because the listed certification scope covers the main solution domains required for data center facility pre-sales capability: power, modular data center, and cooling. Power capability is required because data center facility solutions depend on reliable electrical infrastructure, UPS, distribution, backup power, and energy-efficiency design. Modular DC capability is required because Huawei promotes modular and prefabricated data center approaches that simplify deployment and improve scalability. Cooling capability is also essential because thermal management is one of the largest operational and reliability factors in data centers. The question is checkbox-style and gives only three valid domain options, so all three available options must be preserved. This item belongs to partner certification policy because it validates the solution capability areas required from certified partner specialists.

The exact extract asks what technologies Huawei uses to ensure “on rooftop and under rooftop security.” The correct answer is A, B, C. Rooftop security is mainly about reducing high-voltage DC risk and fire risk in the PV array. Rapid shutdown at the component level helps bring the rooftop PV side to a safer voltage state during emergencies, maintenance, or power outages. AFCI helps detect DC arc faults and shut down the system quickly before an arc can develop into a fire hazard. Under-rooftop security refers to household or building energy storage safety, where Huawei promotes multi-layer ESS safety protection from cells through packs, racks, system, and grid level. Huawei Smart Module Controller materials describe rapid shutdown for personnel and firefighting safety, Huawei AFCI materials confirm intelligent arc detection, and Huawei ESS materials describe five-layer integrated safety design. Because each option addresses a different safety layer, all three are correct. References: Huawei Smart Module Controller product page; Huawei AFCI Technical White Paper; Huawei Smart String ESS Solution.

The exact extract asks which technique can detect and diagnose battery thermal runaway risks. The correct answer is D. Cloud BMS+intelligent internal short circuit detection. Thermal runaway is normally caused by cell-level abuse, internal short circuit, overtemperature, overcharge, or progressive battery degradation. A normal rack controller, battery pack optimizer, or string PCS contributes to system operation and protection, but the specific risk-detection and diagnosis mechanism in the answer choices is Cloud BMS combined with intelligent internal short-circuit detection. Huawei’s battery safety materials emphasize intelligent sensing, real-time detection, early warning, and Cloud BMS-based analysis to identify internal short-circuit and thermal-risk conditions before escalation. Huawei also describes real-time battery-cell detection and rapid shutdown of short-circuit battery packs to prevent thermal runaway. Therefore, the correct option is the one that explicitly combines Cloud BMS analytics with intelligent short-circuit diagnosis. References: Huawei AI BMS and Smart String ESS safety documents.

The exact extract states that the intelligent fusion diagnosis system, or IV & CV fusion, integrates IV scanning and UAV AI image recognition to implement two converged diagnosis modes: IV and UAV associated inspection, site-wide scanning, and cross-verification. The correct answer is A. True. Huawei Smart PV plant O & M increasingly depends on intelligent diagnosis because large PV plants contain thousands or millions of modules and strings. IV scanning helps detect electrical performance abnormalities such as mismatch, degradation, string faults, and underperformance. UAV AI image recognition adds visual inspection capability, detecting hot spots, dirt, broken modules, shading, physical damage, or abnormal module appearance. By fusing IV data with computer-vision inspection, the system can cross-check electrical and visual evidence, improving fault-location accuracy and reducing manual inspection workload. The statement correctly describes the convergence of IV diagnosis and UAV AI inspection in Smart PV Plant O & M. Reference: Huawei HCSA-Sales-Smart PV V2.0 Smart PV Plant Solution training extract.
