2.Make sure the cable polarity is correct and voltage is less than 1100V
3.Switch on the build-in DC isolator at the bottom of the inverter.
4.Switch on the PV/Battery Array and DC isolator next to your inverter, if you can not
find this switch, skip this step.
5.Switch on the Solar AC isolator if the inverter is more than 3 meters away from your
switchboard.
6.Switch on the solar supply main switch in the switch board.
