Phocos ANY-GRID HYBRID INVERTER Charger PSW-H (5 KW) 48 v batteries, 220 volts output

If the pump has two hot wires and a safety ground, but no Neutral, you should be able to connect it directly to the 220 V inverter 220 V and Ground output terminals.

  • \$\begingroup\$ How shall I connect the wires? The pump has three wires, two black (each accepting 110 v, and one green (ground). While the output of the inverter has only two wires, one hot 220 v and the other (neutral?). \$\endgroup\$

  • \$\begingroup\$ The green wire is the safety ground - it will be connected to the frame of the motor and does not normally carry any current. Just connect the two black wires to the two output wires of the inverter. \$\endgroup\$ Apr 7, 2021 at 15:34
