Deep Search Intent Expansion — Engineering & Procurement FAQ


Operations & Reliability


Q1 — Can the system maintain power through continuous storms?


A: Yes. The 80W PV + 40Ah LiFePO₄ configuration in Nanning, Guangxi was validated for ≥3-day autonomy during August–September multi-storm blackout periods.

Q2 — Will fog condensation cause power collapse on the panels?


A: No. Hydrophobic, anti-corrosion PV surfaces and MPPT control suppress fog-loss effects that are common on South China slopes.


Q3 — Can high humidity shorten the battery service life?


A: No. The LiFePO₄ battery is housed in a sealed cylinder cabin that prevents moisture ingress, sulfation, and capacity decay at 90–95%RH.


Q4 — Will insects or small animals damage wiring and connectors?


A: No. The sealed composite enclosure blocks insect ingress and protects cable terminations from corrosion and mechanical damage.


Safety & Emergency Response


Q5 — Can slope-movement alarms reach emergency teams quickly?


A: Yes. SCADA-linked mobile alerts typically reach maintenance or safety teams within about five minutes after deformation thresholds are exceeded.


Q6 — What happens if backhaul or communication links drop?


A: Offline alarms and local event logs are triggered to avoid blind spots in landslide early-warning, supporting later analysis for government agencies.


Q7 — Does the system help increase overall disaster-response speed?


A: Yes. Continuous telemetry from Nanning slopes enables earlier road closure decisions, evacuation planning, and construction-site risk control.


Cost & Deployment


Q8 — Will this off-grid solution reduce slope-site O&M workload?


A: Yes. Field results in South China show patrol workload reductions of ≥60%, especially on long, steep mountain slopes.


Q9 — Is excavation or cable trenching required for installation?


A: No. The pole-mounted design avoids trenching, which lowers civil-work cost, safety risk, and disruption to existing slope protection structures.


Q10 — Is this system suitable for government and EPC tender projects?


A: Yes. The solution is engineered for disaster-prevention projects and can be supplied with CE/EMC/IP documentation and technical dossiers for tender submission by Shenzhen Kongfar Technology.
