All solar photovoltaic ("Solar PV") power plants use large DC to AC power electronic converters, commonly known as "inverters", to convert the DC power from multiple solar PV panels to the AC electric grid. These inverter solutions are notoriously inefficient at maximizing the amount of power generated, and up to 30% of the available power may be lost. In response to this, panel level inverters (one per Solar PV panel), known as "Micro-Inverters", have been introduced to the marketplace, which dramatically reduce the power lost. However, this technology is extremely expensive and impractical for commercial and utility applications.

所有太阳能光伏（“太阳能光伏”）发电厂都使用大型直流到交流电力电子转换器（俗称“逆变器”），将多个太阳能光伏板产生的直流电转换为交流电网。 众所周知，这些逆变器解决方案在最大化发电量方面效率低下，可能会损失高达 30% 的可用电力。 为此，市场上推出了被称为“微型逆变器”的面板级逆变器（每个太阳能光伏板一个），可大大减少功率损失。 然而，该技术极其昂贵且对于商业和公用事业应用来说不切实际。
