The current produced by photovoltaic cells is a direct current. You need an inverter to turn it into the alternating current that matches the electricity grid. It was no longer just an inverter but a tool that enabled remote monitoring and optimization of individual solar panels (according to the direction of the sunlight, shade, and other variables).
