5.6 Connection Procedure
1. Connection with Municipal Electrical Grid
First disconnect with municipal Grid by breaker, make sure it will
not be connected again even due to accident. Put the terminal of L,
N, and PE into the port which is with mark. Then take the plug to
the inverter
2. Connection with Solar Array
In order to guarantee installation and operation of system
safety, external manual breaker has to be configured at DC side.
The selection of breaker should meet basic current and voltage
capacity. Meanwhile, disconnect AC current first before disconnect
DC units.
Before connect the inverter with solar Arrays, test max series
voltage of solar Arrays, whose value should not be over max input
voltage of inverter. Meanwhile the short current of solar Arrays is
better not to exceed max DC current. Please check the polarity of
solar Arrays before the connection.
The positive of solar Arrays should be connected to positive
port in the inverter and the negative of solar Arrays should be
connected to negative port in the inverter.
