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:

  1. 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。
  2. 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。
  3. 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。
  4. 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。
  5. 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。
  6. 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。

1)?During checking, slight signal deviations are possible.
Heat pump control
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.
