The Shanghai Fengxian Tower Qinhuo PV & energy storage retrofit is a flagship Huijue site-energy integration project. Using 41 m² of unused equipment-room rooftop, the site was fitted with an 8.8 kW PV system and a 204.8 kWh high-capacity battery bank, plus a diesel genset as emergency backup, forming a multi-source intelligent microgrid. With an ATS automatic transfer switchboard and remote data terminals, PV, storage, grid power, and diesel switch automatically. The project greened a traditional telecom base station, cut grid and fuel consumption, kept the site online during grid anomalies, and added remote intelligent O&M—delivering cost reduction, supply assurance, and lower carbon in a model that can be replicated across suburban tower sites nationwide.
Rooftop PV plus high-capacity storage builds a multi-energy complementary system, transforming grid-dependent sites into renewable-powered intelligent stations.
On-site PV self-consumption cuts grid usage and diesel start-stop cycles, reducing electricity, fuel, and on-site O&M spend together.
Automatic switching among PV, storage, and diesel keeps telecom gear powered during grid swings or outages, protecting 24/7 signal continuity.
Maximizes clean solar energy and cuts CO₂ tied to grid consumption, aligning with telecom low-carbon construction policies.

PV generation is consumed on site, sharply reducing grid draw and monthly electricity bills.
Multi-source backup lets storage and diesel cover grid anomalies seamlessly, reducing outage risk.
Fewer diesel starts cut fuel purchase, transport, and scheduled maintenance costs.
PV displaces thermal-grid power, lowering lifecycle emissions and meeting green infrastructure goals.
Integrated data terminals enable remote views of generation, storage, and load, reducing on-site patrols.
Modular PV–storage design allows later capacity growth as base-station power demand rises.
