* In Island mode XVT114G03 produces only 2 phases 120 VAC L-N, 208 L-L which results in lower power than in grid-tied 3 phase mode. The

low value of the range is for full L-L loading while high value of the range is full L-N loading.

†Inverter limits its REbus current to adhere to its AC power rating. Total REbus current capability from multiple REbus sources may safely

exceed this value as the inverter safely limits the amount utilized.

About PWRcell Inverters

The PWRcell Inverter connects to PV Link™ optimizers and PWRcell Batteries to form the PWRcell system for grid-

interactive solar-plus-storage. Upon the loss of grid power, PWRcell Inverters disconnect from the grid and provide AC

power to support protected loads when configured to do so. This capability is referred to as islanding. For more

information, see Island Mode in Section 6.

PWRcell Inverters use the REbus™ 380VDC nanogrid to connect to DC-coupled PWRcell devices. The REbus

nanogrid automates the flow of power to enable plug-and-play setup and operation of PWRcell equipment. For more

information about REbus, visit www.generac.com. In Figure 2-3 PWRcell Inverter (E) is directly connected to PV Link

optimizers (B) and PWRcell Battery (C) on DC (REbus) lines (D). To the right of the inverter are AC lines: 120/240 VAC

or 208 VAC for grid and home loads (G) and protected loads (H).
