The SCC Series Solar LED Controller is engineered as the core control unit for modern hybrid solar street lighting systems. It integrates solar power harvesting, battery management, grid power supplementation and IoT remote monitoring into a single compact device, delivering a stable, energy-efficient and maintenance-friendly lighting solution for outdoor infrastructure projects.
Daytime Solar Charging Mode. During daylight hours, the controller connects directly to the photovoltaic panel and applies a high-efficiency Maximum Power Point Tracking (MPPT) charging algorithm. This technology continuously adjusts the operating point of the solar module, ensuring that the panel always outputs at its peak power under changing sunlight intensity and ambient temperature. The harvested energy is then delivered to the battery bank with optimized multi-stage charging curves, including bulk, absorption and float stages, which maximizes charging speed while preventing overcharging and electrolyte loss. Compared with traditional PWM controllers, the MPPT architecture can increase energy harvest by up to 30 percent, which directly extends nightly illumination duration.
Nightfall Battery Priority Power Supply. As ambient light drops below the configured threshold at dusk, the controller automatically transitions from charging mode to discharge mode and powers the LED luminaire from the battery. The built-in real-time clock and programmable lighting profiles allow users to set customized on/off schedules, dimming levels and midnight power-saving modes according to local traffic patterns. For example, the luminaire can run at full brightness during peak evening hours, dim to 30 percent after midnight, and return to full brightness before dawn. This intelligent scheduling reduces unnecessary energy consumption and prolongs battery cycle life without sacrificing road safety.
The built-in grid complementary function is the core advantage of the SCC controller. When battery capacity drops below the preset threshold caused by continuous rainy weather, the controller automatically switches the load to municipal power without light flickering. Once batteries are fully recharged by solar energy, the system restores solar priority mode, lowering grid power consumption and solving the frequent blackout problem of pure solar street lamps.
This controller supports NB-IoT, LoRaWAN and other wireless communication protocols. It uploads real-time operating data to cloud platforms, allowing managers to check equipment status, receive fault alerts and remotely adjust lighting parameters without on-site inspection. The controller can run preset lighting programs independently when offline, and open APIs support connection with smart city management platforms.
Comprehensive built-in battery protection includes overcharge protection, over-discharge protection, reverse polarity protection, short-circuit protection and temperature compensation, all of which significantly extend battery service life and reduce replacement costs. The device supports stepless brightness adjustment from 0 to 100 percent and is compatible with external passive infrared motion sensors and microwave radar sensors, enabling on-demand lighting that brightens only when pedestrians or vehicles are detected. With a robust electronic design and high-quality components, the SCC controller offers reliable long-term performance and is backed by a 5-year product warranty.
Target Applications and Customer Profile. The SCC Series controller is ideal for municipal road lighting, residential community roads, industrial park pathways, scenic area walkways, parking lots, rural village roads and new rural construction projects. It is particularly valuable for lighting integrators, engineering contractors, municipal procurement departments and solar lighting distributors who require a dependable hybrid solution that avoids the blackout risks of pure solar systems while still reducing energy bills and carbon emissions.
