摘要：隨著全球化石能源（石油，煤炭）越來越接近枯竭，污染日趨嚴重，氣候日益變暖等問題，全球多個國家和地區相繼出臺了法規政策，推動了光伏產業的發展。為了更好的分配光伏能源，廠家對發電量進行統一的計量，并根據使用量進行合理分配，使能源利用更合理。

Abstract: As the global fossil energy (oil and coal) is approaching exhaustion, pollution is becoming more and more serious, and the climate is warming, etc., many countries and regions around the world have successively issued regulations and policies, which have promoted the development of the PV industry.

In order to better distribute photovoltaic energy, the manufacturer measures the power generation uniformly and distributes it reasonably according to the amount used, so as to make the use of energy more reasonable.

1.項目概述  Project Overview

　　在比利時光伏項目中，每一個項目點會安裝一個光伏計量箱。客戶在計量箱內安裝安科瑞ADL400多功能三相電能表并通過RS485通訊方式與網關連接，上行以太網連接至服務器，將采集到的電參量信息實時反饋到管理平臺，配合用戶對光伏發電進行監測和管理。

　　In the Belgian PV project, a PV metering cabinet will be installed at each project site. The customer installs Acrel ADL400 three-phase energy meter in the metering cabinet, and connects with the gateway through RS485 communication mode, and connects the uplink Ethernet to the server. Feedback the collected information to the PV system in real time.
