This inverter is designed with boost+ inverter topology. The DC filter prevents the
penetration of high-frequency line-bound interference. After the voltage equalization by
the capacitor, the inverter converts the direct current from solar power system into
alternating current with the same frequency and phase with the grid. The downstream LC
filter has the purpose of equaling the current. Finally the current flows to the utility grid.
In order to make maximum output power of photovoltaic array, it adopt advanced
MPPT algorithm in the DC boost side.
