What is the alternative to a MicroInverter?


Central/String Inverter:

System Design: Central inverters are typically installed at a central location and connected to multiple solar panels in a series, forming a string. This setup means that the DC electricity generated by all the panels in the string is converted to AC electricity at a single point.

Cost: Central inverters generally have lower upfront costs compared to microinverters. Since they are installed centrally and serve multiple panels, they are more cost-effective for larger installations.

Efficiency: While central inverters might not offer the same level of individual panel optimization as microinverters, they are still highly efficient and suitable for installations without shading or mismatch issues.

Monitoring: Central inverters typically offer monitoring capabilities, although the granularity might not be as detailed as with microinverters. Monitoring is usually done at the string level rather than individual panel level.

Reliability: Central inverters have a proven track record of reliability and have been used in solar installations for many years. They have fewer individual components compared to microinverters, potentially reducing the likelihood of failure.

Space Requirements: Central inverters require dedicated space for installation, usually indoors or in a protected outdoor location. This might be a consideration for installations with limited space availability.

In summary, while microinverters offer advantages such as individual panel optimization and enhanced monitoring capabilities, central inverters provide a cost-effective solution suitable for installations without shading issues or space constraints. The choice between the two depends on factors such as system size, shading conditions, budget, and monitoring requirements.
