Scope
GB/Z 116.2-2026 is the English-translated version of 光伏直驱电器控制器 第2部分：运行模式和显示要求.
GB/Z 116.2-2026 is the Chinese guidance document, identical to IEC TS 63349-2:2022, on the operation modes and graphic display of photovoltaic direct-driven appliance controllers. These controllers manage the energy flow between photovoltaic arrays, the grid, energy storage and loads such as air conditioners, water pumps and refrigerators. The document describes equipment configurations, power flow directions and operating modes, with an overview of typical configurations. It then sets requirements for a user-facing graphic display that shows the real-time operating mode, the generating and consuming equipment, and cumulative generation and consumption in an easy-to-read form. Requirements for the appliances themselves are left to appliance standards. It was issued on 4 January 2026.

Foreword
This document is a standard or guiding technical document.
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents". Drafting.
This document is Part 2 of GB/T (Z)116 "Photovoltaic Direct Drive Electrical Controllers". GB/T (Z)116 has already published the following parts.
---Part 2: Operating Mode and Display Requirements.
This document is equivalent to IEC TS63349-2:2022 "Photovoltaic direct drive electrical controllers - Part 2: Operating modes and display requirements".
The document type has been changed from an IEC technical specification to a national standardization guidance technical document of my country.
Introduction
GB/T (Z)116 sets forth general requirements for the functional, performance, and reliability of photovoltaic direct-drive electrical controllers, as well as... The operating modes and display requirements of photovoltaic direct-drive electrical controllers, and their design, development, testing, certification, and production.
This is intended to provide guidance. GB/T (Z)116 is proposed to consist of the following parts.
---Part 1: General Requirements. This section specifies the functional, performance, and reliability requirements for photovoltaic direct-drive electrical controllers.
---Part 2: Operating Modes and Display Requirements. The purpose is to help understand the operating modes of photovoltaic direct-drive electrical controllers and clarify the overall requirements.
The display requirements are specified, and a display example is provided.
1 Scope
This document specifies the operating modes and display requirements for photovoltaic direct-drive electrical controllers. The user-facing display of the photovoltaic direct-drive electrical controller is also specified.
The interface uses easy-to-understand graphics to display the real-time operating mode of the photovoltaic direct-drive electrical appliances, including the installation and control of the photovoltaic direct-drive electrical appliance system.
The system includes a list of monitoring and control equipment, power generation equipment and cumulative power generation, and power consumption equipment and cumulative electricity consumption. This can stimulate users' interest in new energy sources.
It is fun and helps users understand and use new energy more easily.
The GB/T (Z)116 series standards apply to photovoltaic direct-drive electrical controllers, which can be used in various photovoltaic direct-drive electrical systems.
Appliances, including air conditioners, water pumps, refrigerators, etc. The GB/T (Z)116 series standards only include requirements for photovoltaic direct-drive electrical controllers.
Requirements for electrical appliances are specified in electrical appliance standards. For example, SAC/TC46 specifies the performance requirements for household and similar electrical appliances. Safety.
