NOTE :
If the Power Control is enabled, the connection order of the lines of the grid inverter is important. A difference of 120 degree phase
between L1 to L2 and L2 to L3 between must be maintained (L1-L2-L3 and not, for example L1-L3-L2). A phase difference of 120 º between
between L1 to L2 and L2 to L3 between must be maintained (L1-L2-L3 and not, for example L1-L3-L2). A phase difference of 120 º between
between L1 to L2 and L2 to L3 between must be maintained (L1-L2-L3 and not, for example L1-L3-L2). A phase difference of 120 º between
L1 and L2, between L2-L3 should be maintained. If the network lines are not in that order, an error will be displayed on the LCD and
the inverter will not produce energy.
