Generator Connection
There are two functions with this port:
Allows generator input as power source
Allows second AC output connect. This output can be turned On or Off by setting
battery voltage.
6-1. Preparation
NOTE 1: The overvoltage category of the AC input is III. It should be connected to the
power distribution.
NOTE 2:
Before connecting to grid, please install a separate AC breaker between
inverter and grid. This will ensure the inverter can be securely disconnected during
maintenance and fully protected from over current. The recommended of AC breaker is
40A/300V.
WARNING! It's very important for system safety and efficient operation to use
appropriate cable for generator connection. To reduce risk of injury, please use the
proper recommended cable size as below.
Suggested cable requirement
Nominal Grid Voltage
120VAC per phase
Conductor cross-section (mm

6-2. Connecting to the Generator Input
Please follow below steps to implement generator input connection:
1.
Before making generator input connection, be sure to open DC protector or
disconnector first.
2.
Remove insulation sleeve 7mm for four conductors.
3.
Insert input wires according to polarities indicated on terminal block and tighten the
terminal screws. Be sure to connect PE protective conductor (
) first.
