Micro solar inverter
Micro solar inverters have small individual capacities, generally below 5kW, with common power ratings mainly concentrated in the range of 0.25-2kW. They are acterized by high safety. All micro inverters operate in parallel, and after the modules are connected to the grid, the DC side voltage is only below 80V, reducing the safety risks应用框图
The individual capacity of micro solar inverters is relatively small, generally below 5kW, and common power types are mainly concentrated in 0.25-2kW. Micro inverters have high safety. All micro inverters are operated in parallel, and after connecting components to the power grid, the DC side voltage is only below 80V, reducing the safety risks of the DC side during use and maintenance.
In addition, the micro inverter is equipped with an isolation transformer inside, which can achieve electrical isolation between the photovoltaic modules and the power grid, further reducing safety hazards on the DC side.
Small power micro inverters typically use a Push Pull topology. SCT2A23 provides multiple power sources to control units, drive units, and secondary power sources through the Fly Buck topology. MCU drives MOSFETs directly through low side drive for power conversion.
