The GoodWe GM1000 is a single-phase smart meter designed to accurately measure imported and exported energy in residential and small commercial installations. Its native integration with GoodWe inverters enables export limitation functions, self-consumption optimization, and real-time monitoring via the manufacturer's portals and apps.
Key Features
- Bidirectional measurement (grid ↔ installation) with consumption and surplus recording.
- Export control: supports zero export or regulated limits.
- Highly compatible with GoodWe on-grid and hybrid inverters.
- RS485 (Modbus) for robust and stable communication with the inverter.
- Quick installation in the electrical panel, compact DIN rail format.
Integration and Monitoring
- Direct RS485 communication to the inverter; parameters visible in app/portal.
- Compatible with self-consumption strategies and load management.
- Real-time readings for remote diagnostics and O&M.
Main Electrical Data
- Phases: 1P (1×230 V).
- Rated current: up to 100 A (direct measurement).
- Measurement: bidirectional active; typical accuracy class 1.
- Communication: RS485, Modbus protocol (GoodWe integration).
- Mounting: DIN rail; dedicated measurement and communication terminals.
Installation and Safety
- Connection at the main installation point to measure net flow to the grid.
- Shielded RS485 cable; observe A/B polarity and termination if required.
- Inverter configuration for zero export or limits according to regulations.
Compatibility
- Common GoodWe series: ES / EM / ET / SDT G2 (check firmware).
- Recommended use with GoodWe inverters to ensure advanced functions.
Dimensions and Weight
- Dimensions: N/A
- Weight: N/A
Applications
- Single-phase homes with self-consumption photovoltaic installations.
- Small businesses requiring export limitation or grid injection monitoring.
Note for installers: Place the GM1000 at the grid coupling point, upstream of internal loads, and verify current direction to ensure correct export/import measurement.
