For Utility scale solar projects upto 5 MW in Andhra Pradesh, what is better, Central or string inverters?

For projects on a 5 MW scale, central inverters are more suitable due to their robustness and reliability. String inverters are often more volatile, with many models in the current market not lasting more than three years. Since 2018, FIMER has been supplying the PVS980 series central inverters, which have proven to be reliable over time. The long-term availability of string inverters, especially for up to 25 years, is a significant concern.

Additionally, compliance with CEA (Central Electricity Authority) regulations is challenging with string inverters. FIMER central inverters, such as the PVS980 series, are designed to meet local grid requirements and comply with CEA regulations, making them a more reliable choice for large-scale solar projects.
