The function of the inverter is to convert the generated direct current into alternating current.
Centralized Control: Management and control of solar energy systems at this scale are usually centralized, with monitoring and maintenance performed by utility companies or large-scale operators. Grid Dependence: Solar energy systems tied to the grid rely on it for stability and backup power during periods of low sunlight or high demand.

In general, a distributed architecture using string inverters yields a slight cost advantage in smaller arrays, while central architectures offer the lower cost per watt for larger PV installations. While every project is different, system modeling of first costs and energy production indicates a crossover point at approximately 350 kW-AC.
Distributed architectures that use multiple three-phase string inverters throughout an array are the typical architecture in Europe, but are becoming increasingly common in the high-growth U.S. commercial market for distributed solar PV generation.
