A French research group has compared the performance ratio of 100 PV systems relying on micro-inverters with that of 100 installations relying on string/central inverters. It found the performance ratio is around 79% for both system typologies and that arrays with micro-inverters are more sensitive to environmental factors.
Microinverters and other module-level power electronics can be found on residential rooftops as well as commercial systems. Central inverters are installed in large commercial and utility-scale systems. String inverters are designed for all system sizes. Central inverters are large — in the 1-5 MW range per unit.
Centralized inverters are usually much larger and more powerful, with capacities often ranging from 100 kW to several megawatts. They are commonly used in large - scale solar power plants where thousands of PV modules need to be integrated. The main feature of the centralized inverter system is its simplicity in terms of electrical connections.
Cost-effective: Central inverters are cost-effective, especially in large solar power plants. Their cost per watt is lower than micro-inverters or string inverters. Easy maintenance: Central inverters are easy to maintain and have fewer parts to replace. They also have a longer lifespan, so they must be replaced less often.
