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.

10.7 Intelligent Temperature-Control Technology

The inverter will continuously detect the IGBT temperature and adjust the fan speed
accordingly. When the module temperature is low, the inverter will decrease the fan speed to
lower the device noise and decrease the device operation consumption. As the module
temperature increases, the inverter will increase the fan speed for better heat dissipation.
