The household distributed photovoltaic grid connected power generation system refers to a system located near the user and generally installed on the user's roof, especially suitable for villa roofs. The generated energy is utilized locally and connected to the power grid at a voltage level of 220V/380V.

户用分布式光伏发电系统是一种新型的、具有广阔发展前景的发电和能源综合利用方式，它倡导“就近发电，就近并网，就近转换，就近使用”的原则，不仅能够有效提高同等规模光伏电站的发电量,同时还有效解决了电力在升压及损耗问题。

Household distributed photovoltaic power generation system is a new and promising method of power generation and energy comprehensive utilization. It advocates the principle of "nearby power generation, nearby grid connection, nearby conversion, and nearby use". It can not only effectively improve the power generation of photovoltaic power plants of the same scale, but also effectively solve the problems of power boost and loss.

户用分布式光伏发电系统由光伏方阵(光伏方阵由光伏组件串并联而成)、光伏逆变器、光伏支架、光伏并网箱、控制器(可选)、蓄电池组(可选)、交直流电缆等部分组成。

The household distributed photovoltaic power generation system consists of a photovoltaic array (composed of photovoltaic modules in series and parallel), a photovoltaic inverter, a photovoltaic bracket, a photovoltaic grid box, a controller (optional), a battery pack (optional), and AC/DC cables.

光伏发电系统的核心部件是光伏组件，而光伏组件又是由光伏电池串、并联并封装而成，它将太阳的光能直接转化为电能。

The core component of a photovoltaic power generation system is a photovoltaic module, which is composed of photovoltaic cells in series, parallel, and packaged. It directly converts the solar energy into electrical energy.

光伏组件产生的电为直流电，可以用逆变器将其转换成为交流电后使用，也可全部输送到公共电网。从另一个角度来看，光伏发电系统产生的电能可以即发即用，也可以用蓄电池等储能装置将电能存放起来，根据需要随时释放出来使用。

The electricity generated by photovoltaic modules is direct current, which can be converted into alternating current by inverters for use, or all of it can be transmitted to the public power grid. From another perspective, the electricity generated by photovoltaic power generation systems can be generated and used immediately, or stored by energy storage devices such as batteries, which can be released and used as needed at any time.
