Abstract: 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 correctness of the test method.
Key words: grid-connected inverter; photovoltaic; maximum power point tracking; power analyzer
