In real-world operation of solar street lights, there is an unavoidable reality: consecutive overcast days, insufficient winter sunlight, or installation site shading can all lead to insufficient battery charging, ultimately affecting nighttime illumination. For scenarios with strict lighting continuity requirements — urban secondary roads, campus main roads, border patrol routes — pure solar power carries a "blackout risk."
The Sukite 1280-AC-2.4G was designed specifically to address this pain point. The "AC-2.4G" in the model number clearly points to its two core features: AC/DC Hybrid Complementary Input and 2.4G Wireless Remote Control. When solar charging is insufficient, the controller can automatically switch to AC mains or generator input to supplement battery charge, ensuring the street light system operates stably under any weather conditions.
The specification table on the product panel clearly reveals the 1280-AC-2.4G's design logic — every parameter revolves around three keywords: high power, high reliability, and strong adaptability.
12V battery system is the most universal voltage platform in the solar street light sector, offering a mature supporting ecosystem and the lowest procurement costs. The controller's precise positioning on this platform enables plug-and-play compatibility with the vast majority of 12V LED street light fixtures on the market.
Maximum charging current of 15A gives the controller robust "energy throughput" capability. For a 12V battery system, 15A charging current corresponds to a theoretical maximum charging power of approximately 180W, supporting PV array configurations in the 150W to 200W range. This means that even in regions with moderate sunlight conditions, daily charging requirements for street lights can be met by appropriately increasing solar panel capacity.
Maximum load power of 80W forms an excellent match with the charging capability. An 80W LED luminaire adequately covers medium-power lighting needs such as urban secondary roads, campus main roads, and township highways. While ensuring brightness, the controller provides ample power headroom for the system, supporting future luminaire upgrades or expansion.
The LED output voltage range of 18V to 48V reveals the controller's core technical differentiator: it does not simply pass battery voltage directly to the LED load, but incorporates a built-in step-up constant current driver circuit. In real-world operation, a 12V battery's voltage fluctuates significantly between approximately 10.8V and 14.4V depending on charge/discharge state. The 1280-AC-2.4G's step-up constant current driver boosts and stabilizes the fluctuating battery voltage to any set value within the 18V to 48V range, delivering constant current output that ensures consistent driving conditions for the LED string regardless of battery state of charge — preserving both illumination quality and luminaire longevity.
Maximum solar open-circuit voltage of 50V provides substantial flexibility for PV array configuration. Users can flexibly choose 12V or 24V solar panels in series or parallel combinations based on actual light conditions and installation space. The 50V voltage tolerance provides a generous safety margin for the controller.
The 1280-AC-2.4G's most significant differentiating value lies in its AC/DC Hybrid Complementary power architecture.
How it works: The controller incorporates an AC-DC conversion circuit and can simultaneously connect to solar panels (DC input) and mains/generator (AC input). During operation, the controller prioritizes solar energy for battery charging, maximizing clean energy utilization. When solar charging is insufficient (consecutive overcast days, inadequate sunlight) and battery voltage drops below a set threshold, the controller automatically switches to AC input to supplement battery charge, ensuring the street light system never loses power.
AC input specifications: The controller supports 100-265V wide-range AC input (50/60Hz), compatible with mains standards in the vast majority of countries and regions worldwide. Whether it's China's 220V, Europe's 230V, or North America and Japan's 110V, direct connection is possible without additional transformers.
AC-DC conversion efficiency: The built-in H-PF-12V150W power module achieves efficiency of up to 88% with power factor ≥0.95, maintaining efficient operation even in AC power mode and avoiding energy waste.
The value delivered by this design is multifaceted:
Guaranteed lighting continuity — regardless of weather changes, the street light system always has power available, completely eliminating the pain point of "lights out during consecutive overcast days."
Reduced system configuration costs — in areas with moderate sunlight but accessible mains power, users need not over-configure solar panels and batteries to cope with extreme weather. AC backup ensures system reliability with better overall cost-effectiveness.
Flexible adaptation to different scenarios — in grid-covered remote areas, AC can be primary with solar as supplement; in areas with unstable grid power, solar can be primary with AC as emergency backup.
Another highlight of the 1280-AC-2.4G is its built-in 2.4G wireless remote control capability.
Traditional solar street light controllers typically use buttons or DIP switches for parameter settings, requiring climbing the light pole or opening the controller housing for adjustments after installation. The 2.4G wireless remote allows maintenance personnel to operate remotely from the ground, easily performing on/off control, brightness adjustment, and operating mode switching.
This feature is particularly practical for batch-deployed street light projects — maintenance personnel can complete parameter configuration and commissioning without climbing each pole individually, dramatically improving installation and O&M efficiency.
Consistent with the Sukite 1230-G series, the 1280-AC-2.4G also integrates step-up constant current LED driver functionality within the controller.
In traditional solar street light systems, a controller and a separate LED driver power supply are typically required. The 1280-AC-2.4G combines both into one device. Users need only connect solar panels, battery, LED string, and optional AC input to complete the entire street light system's electrical connection. This integrated design reduces device count, simplifies wiring structure, minimizes failure points, and saves installation space and overall costs.
With its 12V system, 15A charging, 80W load, AC/DC hybrid complementary design, and 2.4G remote control specifications, the 1280-AC-2.4G offers distinct advantages in the following application scenarios:
Urban secondary roads and campus main road lighting — 80W LED luminaires adequately cover medium-width road lighting needs. In regions with frequent consecutive overcast days, AC complementary function ensures uninterrupted illumination.
Solar street lights in areas with unstable grid power — In remote areas with grid coverage but unstable supply, the controller prioritizes solar with AC as backup, reducing electricity costs while ensuring reliability.
Border patrol routes and remote highway lighting — These scenarios have strict requirements for nighttime lighting continuity, and AC/DC hybrid complementary provides dual assurance.
Batch street light projects requiring remote management — The 2.4G remote control enables ground-level remote commissioning and parameter adjustment for batch-deployed street light projects, significantly reducing O&M costs.
The Sukite 1280-AC-2.4G MPPT solar charge controller combines "AC/DC Hybrid Complementary + High-Efficiency MPPT Charging + Step-Up Constant Current Driver + 2.4G Wireless Remote Control" in a four-in-one integrated design, delivering a truly "uninterruptible" solution for solar street light systems.
It resolves the inherent pain point of pure solar street lights "going dark" during consecutive overcast days, while reducing the need for over-configuring solar panels and batteries through AC backup — finding the optimal balance between reliability and economy. For urban roads, campus lighting, and remote highways with stringent lighting continuity requirements, this is a highly integrated control solution worthy of serious consideration.
