Description
Synchronized active and reactive power modulation across mega-plants.
GoodWe SEC3000 is an industrial smart energy controller managing up to 60 commercial inverters and multi-megawatt solar plants, engineered to execute high-speed active/reactive power regulation and utility grid-code compliance in real time.
Large-Scale 60-Inverter Fleet Management
Coordinates multi-megawatt commercial solar arrays across multiple high-speed RS485 channels.
Dynamic Grid-Code & Ramp-Rate Control
Executes utility-mandated active power curtailment, reactive power compensation (Q(U), cos φ), and frequency support.
Multi-Loop Industrial Networking
Multiple isolated communication loops ensure reliable telemetry transmission across sprawling industrial facilities.
Rugged Heavy-Industrial Housing (IP65)
Die-cast outdoor housing with internal thermal dissipation and surge protection for substation mounting.
More product details
Managing sprawling multi-inverter commercial installations requires fast, coordinated control loops to meet utility dispatch demands. The SEC3000 modulates power across 60 inverters synchronously.
- Multi-loop RS485 architecture coordinates dozens of inverters with sub-second response times.
- Real-time zero-export and custom power export caps enforced at the point of common coupling.
- Measures three-phase facility power via external 5 A split-core current transformers.

Turnkey substation installation with industrial SCADA bridging.
Factory-assembled in a robust IP65 outdoor enclosure, the SEC3000 provides high noise immunity and direct bridging to central SCADA and EMS platforms. Supports Modbus TCP protocol for seamless integration into factory SCADA and utility telemetry systems. Internal power supply (100–240 V AC) and overvoltage suppressors protect against electrical transients. IP65 die-cast enclosure installs cleanly on external walls or pad-mounted distribution frames (-30 to +60 °C).
