分配、優化和監測光伏系統的電能是指對太陽能光伏系統中電能的分布、優化和監控。
自消耗優化
AD-PVO 6000 GT
產品介紹
光伏優化器AD-PVO 6000監測建筑物主要連接處的光伏能源饋送。如果經客戶PC優化后的饋送導線超過限定值,最多可選擇三個獨立的負載繼電器。這三個負載繼電器可以單獨參數化,因此可以按階段或逐步切換負載。通過這些切換繼電器,可以選擇電動消耗設備(例如,供暖系統水箱中的電加熱棒、空調裝置或熱泵)。
AD-PVO 6000的主要特點:
- 現場實施能源: 該設備將能量實施在現場,而不是反饋到公共低壓電網中。
- 個人消費優化: 通過應用該設備,將光伏裝置優化為個人消費,從而減輕了對公共電網的負擔。
- 錯誤監測: AD-PCO 6000配備了錯誤消息LED和內置的錯誤消息繼電器,通過這些繼電器,可以在分布柜外部指示錯誤消息(例如,饋送永久故障)或通過聲音信號報警。
- 安裝建議: 建議將AD-PVO 6000直接安裝在能源供應商計數器之后的分布柜中,以確保測量盡可能接近饋電點。該設備對所有三個外導體電壓和中性導體進行測量。
- 電流測量: AD-PVO 6000通過三個外部分裂式電流互感器進行電流測量,這些電流互感器可以節省空間地安裝在計數器之后的三個相位上,無需分離。
- 測量電壓: 光伏優化器通過測量電壓L1接收個人消費能量,從而無需連接單獨的供電電壓。
總體而言,AD-PVO 6000旨在為個人消費優化光伏系統性能,同時提供有效的監測和錯誤報告功能。

SG-Ready | |
With the PV optimizer AD PVO 6000 heat pumps can be signaled that enough PV surplus exists. | |
Thus, the heat pump can raise their storage or flow temperature and increase the personal consumption. | |
The optimizer is compatible with many SG-Ready (Smart Grid Ready) enabled heat pumps. The SG-Ready logo can be found on your heat pump. | |
The SG-ready interface is designed in in most cases as a contact input therefore, the overload relay of the PVO can be used easily as a signal for the temperature increase of the heat pump. | |
What is to be done at a SG-signal, it must be parameterized on the heat pump. | |
Through the three internal load relays, the heat pump can switch multiple states. It can be driven so several power levels. |
