STM Sinewave Inverter Drive Module (Grid Sharing) + CT Input – IDM-5 Ver 2.03

Overview

The IDM-5 (Ver 2.03) is a high-performance SPWM drive board designed for the next generation of Hybrid and Grid-Sharing Inverters. Unlike standard driver boards that simply “switch” power sources, the IDM-5 is capable of intelligent power management. By utilising the included CT (Current Transformer) input, the module can monitor load requirements in real-time and efficiently share the load between your DC source (Solar/Battery) and the AC Grid (WAPDA).

Key Features

• Advanced Grid Sharing: Intelligently supplements solar power with grid power to ensure zero interruptions and optimized electricity bills.

• CT Sensor Integration: Dedicated port for a Current Transformer (CT) to provide precise current feedback and prevent grid backfeeding.

• STM32 Core Intelligence: Driven by an STM32-series microcontroller for ultra-fast SPWM calculations and stable sinewave generation.

• Micro-USB Interface: Features an onboard Micro-USB port for easy configuration, debugging, or firmware updates.

• Robust Hardware (Ver 2.03): Improved PCB layout with enhanced noise immunity and thermal stability for 24/7 operation.
