@@@@Combined with features of grid-connected maximum power point tracking (MPPT) capability, this paper introduced a test method for static MPPT efficiency of photovoltaic grid-connected type of inverter. According to requirements of standard, MPPT curves of photovoltaic components were calculated and these curves were simulated with I-V source. Via power analyzer etc test equipment, terminal voltage, current value and power value of grid-connected inverter were measured. MPPT efficiency was obtained by comparing with theoretical maximum power, so as to realize test of MPPT, and data processing. The analysis proved the correct-ness of the test method.
