Grid Connection
The inverter is connected to the grid through AC bus bars which are located on the left bottom of the field
wiring area of the inverter which are labeled A, B, C, and N. The minimum cable size is 1 AWG for both H4
and H6, and 300kcmil for the H2 model. The torque value for AC terminal connections is 40 lb-ft. The
maximum AC overcurrent protection is 125A for the H6 model, 150A for the H4 model, and 400A for the H2
model.
NOTE: The AC service must be a three phase wye connection and the neutral conductor must be used.
DANGER!
Electric shock can result from handling the components with high-voltage present.
Please be sure that all voltage sources are disconnected and cannot be accidentally energized.
CAUTION!
The inverter AC connections must have the proper phase rotation in order to connect to the grid and
operate. Proper rotation is A-B-C. Please check with a phase rotation meter.
If the phase rotation is incorrect an error will be displayed on the user interface and the inverter will not
connect to the grid, if this happens reverse any two phases to correct the rotation.
