What are central and string solar inverters and how do

The cost of cables is usually 33% higher with central inverters than with string with power losses that are 1% greater. As many PV strings rely on one inverter, equipment failure could mean greater downtime losses. Central inverters take up more land area as they need to be housed, and possible shading losses from this need to be considered.
