1. 项目概述 Project overview:
一家做光伏发电的公司，在确认了我司PZ96L和AMC96L的协议可以跟他们目前使用的太阳能逆变器对接后，选择购买这两款表来作为光伏交流部分的电量统计，来确保不会把光伏产生的电流输送向国网。
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.
