PV Network Control Unit

Suzhou Ruitai is a reliable manufacturer of PV Network Control Unit, this high-performance NCU supports reliable communication and efficient O&M in complex outdoor environments. Its advanced network topology and protection architecture help ensure uninterrupted system operation.

Combined with comprehensive solutions and after-sales support, it simplifies O&M work and significantly reduces labor costs throughout the solar power plant lifecycle.

Core Algorithm

The PV Network Control Unit serves as both a communication gateway and the execution unit for intelligent tracking algorithms. Through high-frequency sensing and precise control, it adjusts tracker positions in real time.

Millisecond-Level Micro-Weather Sensing: Integrated wind speed, wind direction, and other sensors collect environmental data every 0.5 seconds, completing the process from sensing to decision-making within milliseconds.

AI Self-Learning Algorithms: Built-in algorithms, including Super Track, combine AI, big data, micro-shading models, and bifacial irradiance models. In complex terrain or diffuse-light conditions, the system automatically calculates the optimal tracker angle to maximize energy capture.

Multi-Level Wind Protection: The system adjusts tracker positions according to wind direction, keeping PV modules parallel to the wind to reduce wind impact. It supports three wind-protection levels:

Level 1 is triggered when wind speed reaches ≥10 m/s for 60 seconds;

Level 2 at ≥12 m/s for 30 seconds;

Level 3 at ≥15 m/s for 5 seconds.

At Level 3, the tracker moves directly to a 5° safety stow position. When wind speed remains at ≤8 m/s for 300 seconds, the system automatically returns to tracking mode.

All-Scenario Solutions

Distributed Multi-Hop Relay Networking

For widely distributed solar equipment, the system provides a power line carrier (PLC) communication solution.

A data collector creates a multi-level routing table, allowing devices without a direct connection to communicate through primary devices using multi-hop relays.

This eliminates the need for additional relay equipment and helps prevent communication issues caused by long installation distances.

Predictive Intelligent Inspection

Combined with drone infrared scanning and edge-based fault diagnosis, the system helps identify aging cables and overheating risks at connection points.

AI analyzes real-time current and voltage deviations to detect potential faults early, shifting O&M from reactive repair to proactive prevention.

Tiered Emergency Response

The system follows a standardized emergency response process when NCU communication is interrupted.

In sunny conditions, it can switch to a local optimal tilt angle to maintain basic power generation.

During extreme weather, trackers can be quickly moved to a safe position through a backup communication link or on-site manual operation to reduce potential losses.

Ruitai Services and After-Sales Support

Firmware and Parameter Management

Regular technical training helps O&M teams improve their independent maintenance capability and keep equipment operating reliably over the long term.

FAQ

Q: What devices can be connected to an NCU?

A: The PV Network Control Unit can connect to a wide range of intelligent PV devices, including TCUs, solar trackers, PV communication boxes, weather stations, sensors, SCADA systems, and IoT monitoring platforms.

Q: Can the NCU operate in harsh outdoor environments?

A: Yes. Many PV power plants are installed in deserts, Gobi regions, or areas with extreme cold. Ruitai’s industrial-grade NCU features an IP65 protection rating, an operating temperature range of -40°C to 70°C, electromagnetic interference (EMI) resistance, and lightning/surge protection.

Q: Can the NCU be used for fixed-tilt PV systems?

A: Yes, though its primary value lies in scenarios requiring device communication management.

For fixed-tilt PV systems that incorporate multiple inverters, environmental monitoring equipment, or intelligent O&M systems, the NCU can also be used for data management.
