GoodWe: PV and hybrid inverters, site meters and residential batteries

GoodWe supplies solar and hybrid inverters, site meters, batteries and energy-management equipment for residential and commercial installations.

Summary

Best for
Projects selecting an inverter, compatible storage and site measurement as a coordinated system.
Less suited to
Assuming a battery communications link or controller protocol document describes every inverter's external interface.
Deployment
PV inverter or hybrid inverter, site meter, compatible battery and selected communications equipment.
Data in
PV and site energy measurements, battery status and model-specific monitoring or EMS interfaces.

Overview

GoodWe supplies PV inverters, hybrid inverters, batteries and associated energy-management equipment. Its company profile describes a portfolio extending from residential systems to larger commercial and utility applications. For a residential storage project, the inverter, site meter and battery form distinct parts of the energy path rather than interchangeable smart-energy accessories.

The ET G2 is a three-phase high-voltage hybrid inverter family. The GM3000 measures three-phase site flows, while Lynx D supplies stored energy through a compatible battery arrangement. Comparing those roles helps establish what is measured, what is converted and what is stored before selecting the reporting or control interface.

Offering

The ET G2 series spans nominal outputs from 6 to 15 kW and uses two or three MPPTs depending on the model. GoodWe describes parallel operation with up to four units and an integrated dry contact for external loads. These are inverter-system capabilities, distinct from the capacity of an attached battery.

The GM meter page separates single-phase GM1000 and GM1000D variants from the three-phase GM3000. Lynx D model LX D5.0-10 provides 5 kWh of usable energy per unit and a dedicated battery-management system. The manufacturer describes modular parallel expansion and compatibility with selected GoodWe residential storage inverters.

Products and platforms

  5. PV building materials

    Building-integrated photovoltaics

    PV building materials remain a product category in the current official catalogue.7

Technology

GoodWe's product ecosystem includes communications accessories and separate controllers in addition to the inverter itself. The SEC3000 download page lists a third-party EMS Modbus protocol document. That is useful evidence of a documented integration path for that controller family, but it is not a register map for every residential inverter or energy meter.

The Lynx D page describes remote diagnosis and updates through the inverter, while the GM meter page describes measurement and integration with compatible inverter and SEMS systems. This research keeps those internal system roles separate from external monitoring access. Exact serial settings, register layouts and permitted controls require the relevant model and firmware documentation before implementation.

Markets

The ET G2 targets homes needing three-phase PV conversion and storage integration, with a range of power ratings to match different demands. The number of MPPTs affects array design, while the battery selection affects stored energy and the supported system arrangement. Neither characteristic replaces a measurement of the building's actual grid exchange.

The GM3000 supplies three-phase voltage, current, power and energy information for that measurement role. Lynx D then provides modular storage capacity, with the product page describing both self-consumption and backup uses in compatible systems. A useful comparison therefore distinguishes inverter power, battery energy and site-meter capability instead of reducing the installation to a single capacity number.

Company

GoodWe's company profile states that it was founded in 2010 and listed on the Shanghai Stock Exchange in 2020 under stock code 688390. It publishes its address in Suzhou, China, and describes a product range spanning inverters, batteries and other smart-energy equipment. Those corporate facts are separate from any one regional product approval or configuration.

The product catalogue groups residential, commercial and utility equipment separately. Its regional pages and download resources should therefore be retained with an equipment specification: a familiar family name alone can cover several model ratings or market variants. This profile focuses on the documented ET G2, GM meter and Lynx D roles, leaving unreviewed interface details explicit rather than filling them from third-party assumptions.
