Inverter/Charger Installation
AC Wiring for a Triple-Inverter System
1.Prepare power distribution bars (supplied in
2.Mount the nine breakers on the din rail and install power distribution bars as follows:
a)Two distribution bars, L1 and L2 at the input (top) terminals of the INV1, INV2 and INV3 Grid breakers.
b)Two distribution bars, L1 and L2 at the input (top) terminals of the INV1, INV2 and INV3 Gen breakers.
c)Two distribution bars, L1 and L2 at the output (bottom) terminals of the INV1, INV2 and INV3 AC Load breakers.
3.Connect L1 and L2, AC wiring from each INV Grid breaker to the corresponding AC Input (AC1) terminal on each of the three inverters.
4.Connect L1 and L2, AC wiring from each INV Gen breaker to the corresponding AC Input (AC2) terminal on each of the three inverters.
5.Connect L1 and L2, AC wiring from each INV AC Load terminal from each of the three inverters, to the corresponding AC INV Out breaker terminal in the PDP.
6.Connect L1 and L2, AC Load wiring to the INV Out (AC Load) power distribution bar.
7.Connect L1 and L2, AC wiring from the Generator disconnect to the Gen breaker power distribution bars.
8.Connect L1 and L2, AC wiring from the Utility Grid distribution panel to the Grid breaker power distribution bars.
9.Connect neutral wiring from INV1 (supplied with PDP), INV2 (supplied in
10.Connect ground wiring from INV1 (supplied with PDP), INV2 (supplied in
Power Distribution bars in the XW Power Distribution Panel accept up to a #2/0 AWG cable (maximum). See Figure
