AC Rewiring for Dual-Inverter Power Panel Installations
NOTE: The following procedure is for a dual-inverter
power panel system. If your system is only a single-
inverter power panel system, disregard the steps that
refer to components that are not present.
NOTE: Use appropriate sized wire and circuit breakers
(if needed) for all wiring added to the installation.
THHN #6 AWG wire is recommended.
1. Inside the power panel, locate and label wires 1A and 1C from inverter-1
and wires 2A and 2C from inverter-2 as labeled in Figure 2-9.
2. Inside the power panel, locate and label terminals 1B, 1D, 2B and 2D as
labeled in Figure 2-9.
3. Inside each GTI, locate and label the terminals 1B, 1D, 2B, and 2D as
labeled in Figure 2-9.
4. Remove wire 1A from terminal 1B in the power panel.
a.
Use a wire nut to add a sufficient length of wire to wire 1A to reach
terminal 1A in GTI-1.
b.
Connect the extended wire 1A to terminal 1A in GTI-1.
5. Remove wire 1C from terminal 1D in the power panel.
a.
Use a wire nut to add a sufficient length of wire to wire 1C to reach
terminal 1C in GTI-1.
b.
Connect the extended wire 1C to terminal 1C in GTI-1.
6. Remove wire 2A from terminal 2B in the power panel.
a.
Use a wire nut to add a sufficient length of wire to wire 2A to reach
terminal 2A in GTI-1.
b.
Connect the extended wire 2A to terminal 2A in GTI-2.
7. Remove wire 2C from terminal 2D in the power panel.
a.
Use a wire nut to add a sufficient length of wire to wire 2C to reach
terminal 2C in GTI-1.
b.
Connect the extended wire 2C to terminal 2C in GTI-2.
8. Add a neutral wire (NEU) to the NEUTRAL BAR in GTI-1 and connect it to
the NEUTRAL BAR in GTI-2.
9. Add a neutral wire (NEU) to the NEUTRAL BAR (NEU) in the power panel
and connect it to either GTI-1 or GTI-2.
10. Add a wire to terminal 1B in the power panel and connect it to terminal 1B
in GTI-1.
11. Add a wire to terminal 1D in the power panel and connect it to terminal
1D in GTI-1.
12. Add a wire to terminal 2B in the power panel and connect it to terminal
2B in GTI-2.
13. Add a wire to terminal 2D in the power panel and connect it to terminal
2D in GTI-2.
