The 200W solar–grid hybrid power system provides uninterrupted energy for river monitoring in rainy Chengdu, China. Hybrid switching ensures continuous hydrology data during floods, while reducing grid dependency and long-distance maintenance costs.
Below are procurement and engineering takeaways designed for water bureaus and project technical reviewers evaluating continuity risk, lifecycle cost, and flood-season reliability:
1️⃣ Hybrid solar plus grid fallback reduces single-energy outage risk
— Keeps monitoring online when foggy days weaken PV or floods damage cables
2️⃣ 200W PV is configured to prioritize daytime load and battery charging
— Stabilizes telemetry even during overcast periods common in Chengdu
3️⃣ 80Ah storage buffers load spikes and short-term sunlight fluctuation
— Protects data continuity during night transmission and peak upload windows
4️⃣ Automatic switching logic prevents manual intervention during storms
— Improves flood-response readiness and reduces maintenance callouts
5️⃣ Flood-season reliability is improved by water-resistant enclosure strategy
— Reduces moisture-related failures on riverbanks and wetland edges
6️⃣ Remote energy visibility reduces wetland patrol exposure
— Fewer on-site visits during high water and muddy access conditions
7️⃣ Design supports multi-sensor hydrology stations, not only CCTV
— Suitable for water level, flow rate, and water quality telemetry expansion
8️⃣ Lower long-term cable maintenance burden than grid-only deployment
— Reduces post-flood repair cycles and recurring trenching disruptions
9️⃣ Hybrid architecture supports compliance-driven government projects
— Documentation readiness improves tender evaluation efficiency
🔟 Deployed for Chengdu river supervision scenarios in 2025 operations
— Designed for ecological oversight and flood dispatch continuity targets

A hybrid system uses solar as the primary source and switches to grid backup when foggy weather or floods reduce available PV and storage, ensuring hydrology telemetry stays online in Chengdu China.
Solar-only designs can face longer low-irradiance periods during fog and continuous rain. Hybrid fallback reduces continuity risk for flood-season supervision tasks.
The controller monitors PV output and battery voltage. When PV plus storage cannot maintain stable supply for telemetry loads, grid backup activates automatically.
It can support CCTV, water level sensors, flow meters, water quality telemetry, and gateway communication equipment used in river monitoring stations.
A water-resistant anti-corrosion enclosure and elevated mounting reduce water ingress risk and protect electronics during high humidity and flood-season splashing.
Continuous telemetry helps authorities detect abnormal water level changes earlier and dispatch actions faster with fewer data blind spots.
Solar plus storage continues as available. The hybrid design reduces reliance on grid continuity and improves resilience versus grid-only deployments.
Initial cost can be higher, but lifecycle cost is often optimized by reducing trenching, cable repair after floods, and emergency maintenance visits.
Yes. Hybrid continuity design, remote OandM readiness, and documentation structure align with common tender evaluation requirements for public water projects.
Yes. PV and storage can be adjusted for higher loads or expanded sensor suites across multiple river sections.
