  Abstract:This article introduces the application of PZ96L and AMC96L in Vietnam photovoltaic inverters. Right now, grid companies usually require photovoltaic grid-connected systems to be irreversible , that is, the electricity generated by photovoltaic grid-connected systems is consumed by local loads, and excess electricity is not allowed to supply to the grid. The system can regulate power generation in order to prevent the photovoltaic grid-connected system from generating reverse power.

  1. 項目概(gài)述(shù) Project overview:

  一家(jiā)做光(guāng)伏發電的(dí)公司，在(zài)確認了我司PZ96L和AMC96L的(dí)協議可以(yǐ)跟他(tā)們目(mù)前使用(yòng)的(dí)太(tài)陽(yáng)能(néng)逆(nì)變(biàn)器對接(jiē)後(hòu)，選擇購(gòu)買這(zhè)兩(liǎng)款(kuǎn)表(biǎo)來作為光(guāng)伏交(jiāo)流部分的電量(liáng)統計，來(lái)確保不會把(bǎ)光(guāng)伏產生(shēng)的電流輸(shū)送(sòng)向國網(wǎng)。

  The photovoltaic power generation company in Vietnam, after confirming that our company’s PZ96L and AMC96L protocols can be connected to their current solar inverters, they chose to purchase these two models as the electricity statistics of the photovoltaic AC part to ensure that the electricity generated by photovoltaic will not be sent to the state grid.
