Sungrow's inverter meets the abovementioned requirements.

10.6 MPPT

Maximum Power Point Tracking (MPPT) is a technique that the inverter uses to get the
maximum power from the PV arrays. PV arrays have a complex relationship between
solar irradiation, temperature and total resistance that produces a non-linear output
efficiency known as the I-V curve.
