4.3 Detail of function ◐ MPPT(Maximum Power Point Tracking) control and operation method • The output characteristics of the PV cell change according to the surrounding temperature, humidity, and the amount of sunlight radiation. So that, PV cell operates with the MPPT control, and the PV cell starts the MPPT DC-DC converter at the PV power rated voltage.
• If a conversion gain is not set correctly when inputting or outputting numerical values from Analog data, an error will occur. At this time, it is necessary to readjust the conversion gain. • The current control gain can adjust the amount of current control by adjusting the feedback amount of line current control.
4.5 Basic operation and stop ◐ Operation 1. Check, there is no abnormality in the entire wiring. Make sure that the polarity of PV array input and battery input is correct. The system may be damaged at the time of incorrect connection. If there is no abnormality, switch on the circuit breaker on PV input side and battery input side to enable KEYPAD.
