When using our 3phase 220VAC output solar inverter, we recommend inputting 305V direct voltage.1) The quantity of each group solar panel(Q1) =305VDC/the direct voltage of each solar panel2) The power of each group solar panel(P1) =The power of each solar panel * The quantity of each group solar panel(Q1)3) Total number of solar panel groups(Q2)=The power of motor *1.5/The power of each group solar panel(P1)For example:About 5.5KW water pump, input 3PH 220VAC,each solar panel :250W, 60VDC, so how the Solar panel combination is ? 1) The quantity of each group solar panel(Q1)=305V/60V=5 pcs2) The power of each group solar panel(P1)=250W*5=1250W3) Total number of solar panel groups(Q2)=5500W*1.5/1250W=7 groupsIn this case, we need 5 pcs connected in series by 7 in...
