At NumiTron Power Systems, we’ve developed a next-generation smart inverter system designed for high-performance power conversion, control, and communication.
Leveraging the advanced capabilities of the STM32G4 microcontroller, our inverter controller offers superior processing power, precise control, and enhanced reliability, ideal for modern solar, UPS, and distributed energy applications.
KEY FEATURES
• STM32G4 Based Control
Upgraded from STM32G0, the STM32G4 provides the processing headroom needed to support advanced features, such as inverter parallelisation and Phase Locked Loop (PLL) synchronisation.
• Parallel Inverter Support (Up to 40kVA)
Up to four inverters can now operate in parallel, enabling scalable power delivery with precise coordination and load sharing.
• Advanced Communication Interfaces
Integrated CAN and serial communication protocols allow seamless interaction across multiple inverters and systems, supporting robust distributed control.
• Dual Closed Loop PID Control
Our system uses both current and voltage feedback loops to ensure:
• Excellent line/load regulation
• Fast transient response
• Accurate and stable AC output under dynamic conditions.
• IGBT-Based Power Stage (48V System)
Designed for low switching losses and high efficiency, driven by high-resolution PWM from STM32G0/STM32G4 with ADC + DMA + timer-triggered feedback.
• Lithium Battery BMS Support
Native support for lithium battery management systems enables intelligent communication and protection of batteries.
• User Feedback & Diagnostics
Onboard LED status indicators provide real-time system feedback and diagnostics.
