What legislation does the inverter need to comply with? Development engineers at SMA face this question with every launch into a new market.
Almost everyone is familiar with the shiny panels (or photovoltaic modules in technical terms) that can usually be seen on rooftops, yet very few know anything about their corresponding devices in the basement (they’re not always in the basement, but more on that later). These devices are called inverters and they are worth knowing about, not merely because of their distinctive names such as “Sunny Boy” but also due to their critical function in PV plant. So what is the actual purpose of an inverter and what must it be capable of?
