What is a central inverter?
The inputs to central inverters are most often combined dc circuits from many (or all) strings in the array that feed a small number of integrated MPPTs. The likelihood of encountering a central inverter on a project increases with project size and age. Utility-scale projects above ~10 MW are the most common application today.
Why are central inverters so popular?
Some of the reasons for central-inverter dominance at larger scales are as follows: Lower capital expenditure (CAPEX): While string inverter costs have come down, central inverters are usually cheaper upfront (in dollars-per-watt). Contact your inverter manufacturer for the latest pricing estimates.
Will my project have a central inverter?
The likelihood of encountering a central inverter on a project increases with project size and age. Utility-scale projects above ~10 MW are the most common application today. Large C&I and smaller utility-scale projects from just a few years ago are likely to have central inverters as well, for reasons we’ll touch on in the next section.
Are central inverters better than string inverter?
Fewer equipment areas: Developers will inherently need fewer central inverters than string inverters for the same overall project capacity, leaving more space for the PV array and less for inverters and balance of system components. Lower perceived risk: Central inverters are more mature than string inverters.
How many kilowatts can a central inverter handle?
Pad-mounted central inverter co-located with a medium-voltage transformer. The first PV inverters were developed in the 1980s as a spinoff of drive system technologies. At the time, all models could be considered central inverters rated to handle no more than a few kilowatts.
What is inverter based Inertia?
Inverter-based inertia & improved short-circuit ratios to ensure stable power delivery during critical disturbances. Reduced harmonic values suitable for the most difficult grid conditions. Enables rapid, decentralized grid restoration, safeguarding the energy supply during outages.
