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.

戶(hù)用分布式光伏發(fā)電系統(tǒng)是一種新型的、具有廣闊發(fā)展前景的發(fā)電和能源綜合利用方式，它倡導(dǎo)“就近發(fā)電，就近并網(wǎng)，就近轉(zhuǎn)換，就近使用”的原則，不僅能夠有效提高同等規(guī)模光伏電站的發(fā)電量,同時(shí)還有效解決了電力在升壓及損耗問(wèn)題。

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.

戶(hù)用分布式光伏發(fā)電系統(tǒng)由光伏方陣(光伏方陣由光伏組件串并聯(lián)而成)、光伏逆變器、光伏支架、光伏并網(wǎng)箱、控制器(可選)、蓄電池組(可選)、交直流電纜等部分組成。

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.

光伏發(fā)電系統(tǒng)的核心部件是光伏組件，而光伏組件又是由光伏電池串、并聯(lián)并封裝而成，它將太陽(yáng)的光能直接轉(zhuǎn)化為電能。

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.

光伏組件產(chǎn)生的電為直流電，可以用逆變器將其轉(zhuǎn)換成為交流電后使用，也可全部輸送到公共電網(wǎng)。從另一個(gè)角度來(lái)看，光伏發(fā)電系統(tǒng)產(chǎn)生的電能可以即發(fā)即用，也可以用蓄電池等儲(chǔ)能裝置將電能存放起來(lái)，根據(jù)需要隨時(shí)釋放出來(lái)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.
