Application Microinverters Power conversion materials Micro-inverters are installed in each panel to generate the maximum power from each of them. AC can be generated in the micro-inverter, or in a high power system for the complete installation Power handling is much less than in string inverters, in the range of 300 watts. This implies: Higher switching frequencies are possible Core size is smaller because of the lower power, but also because of the higher frequency Mid size standard shapes are applicable, but also planar cores
