Overview
The GoodWe Smart Meter GM1000D is a single-phase DIN-rail meter designed to work inside the GoodWe inverter ecosystem. It is best suited to homes that want cleaner visibility into grid import, export, and household load behavior without adding a separate third-party monitoring stack.
Core Features
- Single-phase smart meter with RS485 communication for GoodWe-compatible inverter and SEMS workflows
- Ships with 2 included 120A:40mA current transformers for dual-sensor measurement
- Designed for voltage, current, power, and energy measurement rather than utility billing settlement
- DIN-rail form factor that fits installer-led solar and storage switchboard work more naturally than plug-in consumer monitors
Installation
The official GoodWe source set presents GM1000D as a DIN-rail mounted indoor meter with IP20 protection. The dedicated GM1000D manual shows the two CT inputs directly on the meter body and confirms the included current transformers are part of the standard package.
Compatibility And Integration
GM1000D is built around RS485 communication and is intended to work with compatible GoodWe inverters and the SEMS monitoring platform. That makes it more attractive for GoodWe-based solar and storage projects than for buyers who want a broad standalone local-integration ecosystem.
Measurement And Selection Notes
For comparison shopping, the most important points are that GM1000D is a single-phase model, uses 2 CTs, supports current measurement up to 120A, and carries Class 1 voltage/current plus active-energy accuracy with Class 2 reactive-energy accuracy. Those details matter when comparing it against simpler single-CT meters, direct-connected DIN-rail meters, or Home Assistant-first options.
Limits
The reviewed official source set does not present GM1000D as a local API product, a Home Assistant-native product, or a cloud-optional open-integration meter. Its strongest fit is inside GoodWe-led monitoring and export-control workflows rather than broad DIY automation use.
