GoodWe GM330 Three-Phase Smart Meter

The GoodWe GM330 is a three-phase smart meter designed to measure local electricity consumption and demand with 0.5% Class accuracy. It features flexible CT (current transformer) input supporting large currents, making it suitable for charge control in hybrid inverters and zero-feed applications.

The meter operates across a wide voltage range of 230–400 Vac (line-to-line), accommodates 50/60 Hz grid frequencies, and communicates via RS485 over distances up to 1000 m. With IP20 ingress protection and operating temperature range of −25 to +60 °C, it is designed for integration with GoodWe's SEMS Portal monitoring system.

Mounted on standard DIN rail with compact dimensions (72 × 85 × 72 mm) and low power consumption below 5 W, the GM330 provides cost-effective power control for single C&I inverter installations with large load consumption.
