GoodWe Smart Meter GMK110

A compact single-phase smart meter for GoodWe solar homes that want cleaner load visibility, export control, and a simpler inverter-native metering path than a more general-purpose third-party Modbus setup.

Why it fits

The GoodWe Smart Meter GMK110 is a narrow DIN-rail single-phase meter aimed at residential GoodWe systems that need load monitoring and export-power control rather than a standalone app-first monitoring platform.

What stands out

GoodWe's official product page and current datasheet position GMK110 as a 1P2W meter with RS485 communication, one included 120A CT, and Accuracy Class 1.0. That makes it a stronger fit for inverter-led solar workflows than for buyers who want broad local integrations or general-purpose building automation.

What to watch

The reviewed official source set points normal monitoring toward the SEMS ecosystem, so this page should be treated as cloud-tied and inverter-ecosystem dependent rather than a local-first meter with native Home Assistant or local API support.
