Inverter type | Capacity | Technique |
Central inverter | 250 kW to 01.25 MW | It is commonly used in MW scale photovoltaic power plants in India. A single inverter controls the major portion of the plants. |
String inverter | 05 to 20 kW | It is used in smaller photovoltaic installations including rooftop systems, and some MW scale plants in India. A single inverter controls a single or limited string of modules. They offer multiple controls at a more basic level compared to central inverters, hence, reducing module mismatch losses and simplifying plant maintenance. They are typically mounted outdoors. |
Domestic inverter | 01 to 05 kW | It is typically used for domestic rooftop applications. That May be in a grid-tied or stand-alone mode. |
Micro inverter | 100 to 400 W | It uses novel technology with controls the output of each module individually converting it into AC. It is currently used in pilot small-scale installations only, but have a promising roadmap for wide applications. |
