Our solar‑grid complementary MPPT solar street light controller is a comprehensive intelligent control unit specially designed for outdoor solar street‑light systems. It perfectly integrates solar battery charge‑discharge management function and LED lamp constant‑current driving function. Equipped with industry‑proven built‑in MPPT maximum power point tracking algorithm and battery SOC state‑of‑charge algorithm, the device can dynamically track the maximum output point of photovoltaic panels under changing sunlight conditions all day long. It keeps solar panels running at maximum‑power output status continuously, greatly improves solar‑energy utilization and conversion efficiency, reduces energy waste, and brings higher energy‑saving performance for your whole lighting project.
Multiple mainstream wireless network protocols are fully supported, including NB‑IoT, LoRaWAN as well as LoRaMesh. Customers can complete remote parameter configuration, real‑time device status monitoring, fault alarm notification and centralized intelligent management via cloud management platform. The controller reserves external sensor interfaces, which can be connected with motion sensors and human‑body induction sensors. It supports flexible on‑demand lighting mode and delayed switch‑on & switch‑off function. You can set different brightness levels and delay time according to actual road conditions, pedestrian flow and vehicle flow, to satisfy diversified requirements of municipal, rural and park lighting projects.
Let us look at its complete real‑world working logic. During daytime, the solar controller absorbs sunlight energy through matched solar panels, performs safe charging for storage batteries and stores electric power. When night falls and ambient light weakens, the street light will turn on automatically powered by the solar power stored in batteries throughout the day. Once cars or other vehicles pass by the lighting position, the connected motion sensor will be triggered rapidly. The lamp brightness will instantly rise to higher level, providing sufficient illumination to guarantee safe driving for drivers. Benefiting from the built‑in astronomical real‑time clock and calendar module, the controller can accurately judge dawn arrival according to time logic. When morning comes, it will turn off street lights automatically. The whole working cycle runs fully automatically, zero manual operation and on‑site adjustment are required.
Developed for complex outdoor working conditions, this controller owns IP67 high‑level protection grade. It provides reliable protection against dust invasion, rain splash, moisture and temperature fluctuation. It can work stably in desert, coastal, mountain‑area and other harsh outdoor environments. Multiple‑dimensional built‑in battery protection mechanism covers over‑charge protection, over‑discharge protection, over‑current protection and short‑circuit protection. These protection functions effectively avoid battery damage caused by abnormal working status, greatly extend the whole service life of storage batteries. It supports long‑distance stepless brightness adjustment. Operators can adjust lamp brightness remotely without going to site. Open and secure API interfaces support PLC gateway access and OpenAPI secondary development. System integrators can conveniently dock this controller into their existing smart city lighting management platform. Adopting high‑quality industrial‑grade electronic components, our controller delivers outstanding working reliability. We support 5‑year long‑term product warranty service to remove your after‑sales worries.
This controller has extremely wide application scope. It is widely deployed in municipal urban road lighting, countryside reconstruction lighting projects, residential community and park lighting, highway auxiliary road lighting, industrial park outdoor lighting, scenic‑spot road lighting and other smart outdoor lighting scenarios. By deploying our solar‑grid complementary controller, project owners can effectively cut grid‑power consumption, reduce later‑period manual maintenance workload and maintenance cost, realize unattended, fully‑automatic and intelligent street‑light operation, and achieve better economic and environmental‑protection benefits.
