Replacing an Inverter

1. Turn OFF the StorEdge Connection Unit.
2. Turn OFF the inverter ON/OFF switch, and wait until the LCD indicates that the DC voltage is safe
(<50V), or wait five minutes before continuing to the next step.
WARNING!
If you cannot see the inverter panel, or if a malfunction is indicated on the LCD panel, wait five
minutes for the input capacitors of the inverter to discharge.
3. Turn OFF the AC switch at the distribution panel.

to the backed-up loads.
7. Disconnect the meter, battery, AC and DC wires from the StorEdge Connection Unit.
8. Remove the screws securing the inverter to the mounting bracket and remove the inverter (with the
StorEdge Connection Unit) from the mounting bracket.
NOTE
If you remove the old inverter and do not immediately install a new one, use insulation tape to isolate
each of the AC and DC wires
9. Place the new inverter on the mounting bracket; insert the screws securing the inverter to the
mounting bracket.
10. Connect all the wires to the inverter: Follow the instructions of StorEdge Inverter Connections on page
