Local heroes
Small PV systems in the grid: If small solar PV systems are to be a model of success, they must also be capable of grid integration. Christoph Winter, a photovoltaic systems technician at Fronius, explains how a grid test in Austria is solving this problem. And one thing becomes clear: Just a few simple, local control systems in the inverter can do a lot.
What can be learned from a grid test in Austria? The test in question may be unique, but the findings have more generalized implications.The unusual aspect of the test is that photovoltaics did not previously exist in the area being studied. Researchers and engineers first created the problem that they then wanted to solve. This …
