The SG36KTL-M is equipped with MPPTs for 3 DC inputs to ensure that the
maximum power can be utilized even in different PV modules installation
conditions.
Inversion circuit converts DC power into AC power, which will be fed into the utility
grid via AC terminals. Protective circuits are designed to guarantee inverter safe
operation and human safety.
DC switch is integrated for safe disconnection of DC current. The inverter provides
standard interface RS485 for communication. Inverters are also provided running
records display and parameters configuration via human-computer interface– LCD
display panel.
The principle design is illustrated below:
