Direct from Factory: Certified and High-Efficiency System Modules
Engineering Reliable Autonomy in Off-Grid Agricultural Telemetry
Modern Leit 2 Solar Controllers operate via low-lux micro-crystalline solar cells coupled with high-efficiency Maximum Power Point Tracking (MPPT). Unlike legacy systems reliant on alkaline battery replacements, our dynamic circuits continuously charge integrated ultra-capacitors, guaranteeing a lifetime exceeding 10 years without maintenance overhead.
Optimizing electric power requirements, the controller fires an 11-12V DC impulse with a 12-millisecond pulse width to actuate 2-wire DC latching solenoids. This method mitigates continuous power draw, enabling long-range wireless valve command even during weeks of consecutive sub-optimal solar irradiance.
Engineered for high-humidity, agricultural chemical exposures, and flooded valve boxes, the internal electronic circuit assembly is fully encapsulated in waterproof polyurethane resin. The physical body utilizes UV-resistant polycarbonate engineering plastics, eliminating condensation failure vectors.

Adapting Leit 2 Solar Systems Across Large-Scale Infrastructure Projects
Integrating solar-driven scheduling controllers eliminates diesel fuel operational expenses (OpEx) for remote drip lines. Optimized for high-value crops where exact water control increases yield density and prevents local root hypoxia.
Enables green infrastructure along roadways, highway divider strips, and community parks without trenching across pedestrian walkways or tearing up pavement to install utility power feeds.
Operates autonomously around off-grid microwave repeater stations and wind-power towers. The low-profile structure is dust-proof and runs via integrated solar cells, minimizing utility footprints.
Where Yuxin's Solar, Aluminum, and Off-Grid Controls Excel Globally
Why Our Leit 2 Solar Controller Quotes Lead the Market
In B2B solar controller procurement, a "Cheap" quote must not suggest lower standards of quality or durability. At our smart facility in Yangzhou, we optimize structural margins through vertical integration. Since we operate dedicated lines for high-purity aluminum extrusion (extruding over 25,000 tons annually), the mounting hardware, protective boxes, and structural supports of our outdoor devices are manufactured in-house, avoiding markups from secondary vendors.
Every single Leit 2 solar controller PCB undergoes computer-assisted AOI (Automated Optical Inspection), thermal environmental stress screening (ESS), and complete functional cycle-testing. This reduces factory defects to under 80 Parts Per Million (PPM).
Operating in an integrated cluster enables Yuxin to secure high-efficiency monocrystalline cells, premium components, and pultruded polyurethane composite materials at volume. This safeguards production schedules against global commodity price spikes.
Located near the Beijing-Shanghai Expressway and Ningqi Railway, we ship products directly to Shanghai and Ningbo Ports, ensuring predictable marine transport routes, lower local freight costs, and shorter delivery lead times.
Investing in the Next Generation of Smart Agricultural Controllers
YUXIN's engineering research team is advancing solar control technology. Our forthcoming product iterations focus on three primary pillars of smart agricultural technology:
Integrating sub-GHz low-power wide-area networking directly onto the mainboard. This lets users adjust irrigation schedules remotely via mobile app from up to 10km away.
Using predictive machine learning models to dynamically scale water delivery rates based on current soil hygrometer measurements and regional microclimate forecasts.
Transitioning from standard lithium batteries to eco-friendly hybrid supercapacitors. These components function reliably in extreme ambient environments from -30°C to +70°C.

Technical and Commercial Inquiries About Our Solar Controllers & Factory Services
The Leit 2 controller is designed for reliable, maintenance-free performance in remote areas. Instead of using standard, failure-prone alkaline batteries that need annual replacement, it uses integrated solar panels and advanced capacitor modules to run for years without manual intervention. It drives low-power, 2-wire DC latching solenoid valves using brief electric pulses, which helps conserve energy and ensures reliable watering schedules even in low-sunlight conditions.
You can request a direct factory quote by contacting our sales department with your specifications. Please include your required zone count, wiring lengths, preferred sensor interfaces, and order volumes. We offer customized packaging, private labeling, and custom electrical configurations for bulk purchases, helping you meet specific technical and branding requirements.
Yes, our controllers are equipped with standard dry-contact connections designed to work with most rain, freeze, and soil moisture sensors. When a connected sensor detects soil saturation or freezing temperatures, the controller automatically pauses irrigation cycles to prevent overwatering or pipe damage, resuming normal schedules once conditions improve.
We operate 21 advanced production lines at our ISO9001-certified factory in Yangzhou. By manufacturing key components, such as anodized aluminum frames, in-house, we reduce reliance on external suppliers. Every batch undergoes automated optical inspection, environmental testing, and cycle checks to ensure reliable field performance and consistent quality.
Standard orders are processed and ready for shipment in 20 to 35 days, depending on customization requirements. Our facility is situated close to the Beijing-Shanghai Expressway, allowing direct transport to major shipping hubs, including Shanghai and Ningbo Ports, for efficient international shipping.
