6.1 Connecting Terminals of Inverter
All connecting terminals are at the bottom of the inverter, and the cross
screwdriver is used to remove the terminal cover, which contains DC side
input (PV) terminal, AC side input (motor) terminal, communication terminal
and water level sensor terminal. The DC side input terminal, AC side input
and output terminal, and the grounding terminal are connected by a terminal
block; the communication terminal and water level sensor terminal are
