GoodWe GM330 Three-Phase Smart Meter

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

The meter operates across a wide voltage range of 230–400 Vac (line-to-line), supports 50/60 Hz grid frequencies, and communicates via RS485 over distances of up to 1,000 m. With an IP20 ingress protection rating and an operating temperature range of −25 to +60 °C, it is designed for integration with GoodWe's SEMS Portal monitoring system.

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